President, Chief Executive Officer

National Semiconductor Corporation

Wir fDhlen uns zu Qualitat und Zuverlassigkeit verpflichtet

National Semiconductor Corporation ist fUhrend bei der Her- stellung von integrierten Schaltungen hoher Qualitat und hoher Zuverliissigkeit. National Semiconductor war schon immer Vorreiter, wenn es galt, die Zahl von IC AusfAllen zu verringern und die Lebensdauern von Produkten zu verbes- sern. Vom Rohmaterial Ober Entwurf und Herstellung bis zur Auslieferung, die Qualitiit und die ZuverlAssigkeit der Pro- dukte von National Semiconductor sind unObertroffen.

Wir sind stolz auf unseren Erfolg, der Standards setzt, die fOr andere erstrebenswert sind. Auch ihre AnsprOche steig- en stiindig. Sie als unser Kunde kOnnen sich auch weiterhin auf National Semiconductor verlassen.

La Qualite et La Fiabilite:

Une Vocation Commune Chez National Semiconductor Corporation

National Semiconductor Corporation est un des leaders in- dustriels qui fabrique des circuits integres d'une tres grande qualite et d'une fiabilite exceptionelle. National a ete Ie pre- mier a vouloir faire chuter Ie nombre de circuits integres defectueux et a augmenter la duree de vie des produits.

Oepuis les matieres premieres, en passant par la concep- tion du produit sa fabrication et son expedition, partout la qualite et la fiabilite chez National sont sans equivalents.

Nous sommes fiers de notre succes et Ie standard ainsi defini devrait devenir I'objectif a attaindre par les autras so- cietes. Et nous continuons a vouloir faira progresser notra recherche de la perfection; iI an resulte que vous, qui ~Hes notre client, pouvez toujours faira confiance a National Semiconductor Corporation, an produisant des systemes d'une tres grande qualite standard.

Introduction

Since its creation in 1973, National Semiconductor's Interface design and production teams have produced technically advanced products unparalleled in the semiconductor industry.

Growing from a line of early drivers and receivers, which pioneered the introduction of the TRI-STATEQ!> function, National Semiconduc- tor's Interface product line today is the most comprehensive avail- able-with over 200 devices in a variety of product categories.

Based on its advanced design and process capabilities, National's Interface product line includes:

• The industry's most advanced RS-232 drivers and receivers.

• The industry's most advanced RS-422 drivers, receivers, and transceivers

• The industry's most advanced RS-485 transceivers

• The industry's only offering of over 16 devices incorporating pow- er up/down glitch-free protection

• The industry's first Trapezoidal™ bus transceiver

• The industry's first transceivers for the Future Bus standard

• The industry's first fault protected peripheral driver incorporating a major breakthrough in current sensing and shut down circuitry.

In addition to the detailed Interface product datasheets included in this databook, complete product selection guides can be found at the beginning of each section for quick reference.

The Interface Appendix supplies helpful application notes, terms and definitions, cross references, design and process information and package information.

These Interface devices support and complement Nationals ad- vanced VLSI APPSTM product families. These Advanced Peripheral Processing Solutions or APPS products are families of VLSI peripher- al circuits designed to serve a variety of applications. The APPS prod- ucts are especially well suited for microcomputer and microprocessor based systems such as graphic workstations, personal computers, and many others. National Semiconductor's APPS devices are fully described in a series of databooks and handbooks.

Among the APPS books are the following titles:

MASS STORAGE MEMORY SUPPORT

LOCAL AREA NETWORKS AND DATACOMMUNICATIONS GRAPHICS

All the APPS products currently provided by National Semiconductor and their appropriate APPS Databook title are listed in the Table of Contents of this Databook.

For more information on National Semiconductor's INTERFACE and APPS products contact your local National authorized sales repre- sentative or distributor.

Transmission Line Drivers/Receivers

The common purpose of transmission line drivers and re- ceivers is to transmit data quickly and reliably through a variety of environments over electrically long distances.

This task is complicated by the fact that externally intro- duced noise and ground shifts can severely degrade the data.

The connection between two elements in a system should be considered a transmission line if the transmitted signal takes longer than twice its rise or fall time to travel from the driver to the receiver.

Single-Ended Data Transmission

In data processing systems today there are two basic means of communicating between components. One meth- od is single-ended, which uses only one signal line for data transmission, and the other is differential, which uses two signal lines.

The Electronics Industry Association (EIA) has developed several standards to simplify the interface in data communi- cations systems.

RS-232

The first of these, RS-232, was introduced in 1962 and has been widely used throughout the industry. RS-232 was de- veloped for single-ended data transmission at relatively slow data rates (20 kBaud) over short distances (up to 50 ft.).

RS-423

With the need to transmit data faster and over longer dis- tances, RS-423, a newer standard for single-ended applica- tions, was established. RS-423 extends the maximum data rate to 100 kBaud (up to 30 ft.) and the maximum distance to 4000 feet (up to 1 kBaud). RS-423 also requires high impedance driver outputs with power off so as not to load the transmission line.

Differential Data Transmission

When transmitting at very high data rates, over long dis- tances and through noisy environments, single-ended trans- mission is often inadequate. In these applications, differen- tial data transmission offers superior performance. Differen- tial transmission nullifies the effects of ground shifts and noise signals which appear as common mode voltages on the transmission line.

RS-422

RS-422 was defined by the EIA for this purpose and allows data rates up to 10 MBaud (up to 40 ft.) and line lengths up to 4000 feet (up to 100 kBaud).

Drivers designed to meet this standard are well suited for party-line type applications where only one driver is con- nected to, and transmits on, a bus and up to 1 0 receivers can receive the data. While a party-line type of application has many uses, RS-422 devices cannot be used to con- struct a truly multipoint bus. A multipoint bus consists of multiple drivers and receivers connected to a single bus, and anyone of them can transmit or receive data.

RS-485

To meet the need for truly multipoint communications, the EIA established RS-485 in 1983. RS-485 meets all the re- quirements of RS-422, but in addition, this new standard allows up to 32 drivers and 32 receivers to be connected to a single bus-thus allowing a truly multipoint bus to be con- structed.
