Order this document by MC3487/D Motorolais Quad EIA–422 Driver features four independent driver chains which comply with EIA Standards for the Electrical Characteristics of Balanced Voltage Digital Interface Circuits. The outputs are three–state structures which are forced to a high impedance state when the appropriate output control pin reaches a logic zero condition. All input pins are PNP buffered to minimize input loading for either logic one or logic zero inputs. In addition, internal circuitry assures a high impedance output state during the transition between power up and power down. A summary of MC3487 features include: • Four Independent Driver Chains • • • • • • • QUAD EIA–422 LINE DRIVER WITH THREE–STATE OUTPUTS SEMICONDUCTOR TECHNICAL DATA Three–State Outputs D SUFFIX PLASTIC PACKAGE CASE 751B (SO–16) PNP High Impedance Inputs (PIA Compatible) Fast Propagation Times (Typical 15 ns) TTL Compatible Single 5.0 V Supply Voltage Output Rise and Fall Times Less Than 20 ns DS 3487 Provides Second Source P SUFFIX PLASTIC PACKAGE CASE 648 Driver Block Diagram PIN CONNECTIONS Non–Inverting Input 16 15 14 13 12 11 10 9 Input A 1 2 3 A/B Control 4 5 Outputs B 6 Input B 7 Gnd 8 Outputs Outputs A Inverting Output Control VCC Input D Outputs D C/D Control Outputs C Input C TRUTH TABLE Input Control Input Non–Inverting Output Inverting Output H L X H H L H L Z L H Z ORDERING INFORMATION Device L H X Z = = = = Low Logic State High Logic State Irrelevant Third–State (High Impedance) MC3487P MC3487D Operating Temperature Range TA = 0 to +70°C Package Plastic DIP SO–16 Motorola, Inc. 1995 MOTOROLA ANALOG IC DEVICE DATA 1 MC3487 MAXIMUM RATINGS Rating Symbol Value Unit VCC 8.0 Vdc Input Voltage VI 5.5 Vdc Operating Ambient Temperature Range TA 0 to +70 °C Operating Junction Temperature Range TJ 150 °C Tstg –65 to +150 °C Power Supply Voltage Storage Temperature Range ELECTRICAL CHARACTERISTICS (Unless otherwise noted, specifications apply 4.75 V Typical values measured at VCC = 5.0 V, and TA = 25°C.)
