Quad EIA·422·A Line Receiver

CMOS

The MC34C86 is a quad differential line receiver designed for digital data transmission over balanced lines. The MC34C86 meets all the requirements of standard EIA-422-A while retaining the low-power characteristics of CMOS.

The MC34C86 has an input sensitivity of 200 mVoverthe common mode input voltage range of ± 7 V. In addition, each receiver chain has internal hysteresis circuitry to improve noise margin and discourage output instability for slowly changing input waveforms.

The MC34C86 is pin compatible with the MC3486.

All pins are protected against damage due to electrostatic discharges.

• Typical Power Supply Current: 6 mA

• 2000-V ESD Protection on the Inputs and Outputs

• Typical Propagation Delay: 18 ns

• Typical Input Hysteresis: 75 mV

• Meets the Requirements of Standard EIA-422-A

• Operation from Single 5-V Supply

• High-Impedance Mode for Outputs Connected to System Buses

• TTUCMOS Compatible Outputs

Quad EIA·422·A Line Driver

CMOS

The MC34C87 is a quad differential line driver designed for digital data transmission over balanced lines. The MC34C87 meets all the requirements of standard EIA-422-A while retaining the low-power characteristics of CMOS.

The MC34C87 accepts TTL or CMOS input levels and translates these to EIA-422-A output level. This part uses special output circuitry that enables the individual drivers to power down without loading down the bus. The MC34C87 also includes special circuitry which will set the outputs to a high impedance mode during power up or down, preventing spurious glitches. Each enable pin controls 2 drivers.

The MC34C87 is pin compatible with the MC3487.

All pins are protected against damage due to electrostatic discharges.

• Maximum Power Supply Current: 3 mA

• 2000-V ESD Protection on the Inputs and the Outputs

• TTUCMOS Input Compatible

• Typical Propagation Delay: 6 ns
