Overview
DS3487 Quad TRI-STATE Line Driver May 1998 DS3487 Quad TRI-STATE ® Line Driver General Description National’s quad RS-422 driver features four independent drivers which comply with EIA Standards for the electrical characteristics of balanced voltage digital interface circuits.
The outputs are TRI-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.
Features n n n n n n n Four independent drivers TRI-STATE ® outputs Fast propagation times (typ 10 ns) TTL compatible 5V supply Output rise and fall times less than 15 ns Pin compatible with DS8924 and MC3487 Block and Connection Diagrams Dual-In-Line Package DS005780-1 DS005780-2 Top View Order Number DS3487M or DS3487N See NS Package Number M16A or N16E Truth Table Input H L X Control Input H H L Non-Inverting Output H L Z Inverting Output L H Z L = Low logic state H = High logic state X = Irrelevant Z = TRI-STATE(high impedance) TRI-STATE ® is a registered trademark of National Semiconductor Corporation.
