| MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC34C87/D MC34C87 Product Preview Quad EIA-422-A Line Driver CMOS 16 P SUFFIX PLASTIC DIP CASE 648 1 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 two 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 TTL/CMOS Input Compatible Typical Propagation Delay: 6 ns Typical Output Skew: 1 ns Meets VO = 6.0 V (and VO = - 0.25 V), VCC = 0 V, IO < 100 A Requirement * Operation from Single 5 V Supply * High Impedance Mode for Outputs Connected to System Buses * * * * * * 16 1 D SUFFIX SOG PACKAGE CASE 751B ORDERING INFORMATION MC34C87P MC34C87D Plastic DIP SOG Package BLOCK DIAGRAM C/D CONTROL 12 INPUT D 15 INPUT C 9 INPUT B 7 INPUT A 1 4 8 GND 16 VCC 14 13 10 11 6 5 2 3 OUTPUT OUTPUT OUTPUT OUTPUT OUTPUT OUTPUT OUTPUT OUTPUT D2 D1 C2 C1 B2 B1 A2 A1 This document contains information on a product under development.

For proper operation it is recommended that Vin and Vout be constrained to the range VSS (Vin or Vout) VDD. Reliability of operation is enhanced if unused inputs are tied to and appropriate logic voltage level (e.g., either VSS or VDD).
