Order this document by AM26LS31/D The Motorola AM26LS31 is a quad differential line driver intended for digital data transmission over balanced lines. It meets all the requirements of EIA–422 Standard and Federal Standard 1020. The AM26LS31 provides an enable/disable function common to all four drivers as opposed to the split enables on the MC3487 EIA–422 driver. The high impedance output state is assured during power down. • Full EIA–422 Standard Compliance • • • • • • • Single + 5.0 V Supply Meets Full VO = 6.0 V, VCC = 0 V, IO QUAD EIA–422 LINE DRIVER WITH THREE–STATE OUTPUTS SEMICONDUCTOR TECHNICAL DATA t 100 µA Requirement Output Short Circuit Protection Complementary Outputs for Balanced Line Operation High Output Drive Capability Advanced LS Processing D SUFFIX PLASTIC PACKAGE CASE 751B (SO–16) PNP Inputs for MOS Compatibility PC SUFFIX PLASTIC PACKAGE CASE 648 Representative Block Diagrams PIN CONNECTIONS Non–Inverting Input Outputs Inverting 1 16 VCC 2 15 Input D 3 14 4 13 5 12 6 11 Input B 7 10 Gnd 8 9 Input A Outputs A Outputs D Enable Enable Output Controls Enable Outputs B Enable Outputs C Input C TRUTH TABLE Input Control lnputs (E/E) Non–Inverting Output Inverting Output H L X H/L H/L L/H H L Z L H Z L = Low Logic State H = High Logic State X = Irrelevant Z = Third–State (High Impedance) * Note that the surface mount MC26LS31D device uses the same die as in the plastic DIP * AM26LS31DC device, but with an MC prefix to prevent confusion with the package suffix.
