DS3487 www.ti.com SNLS355C – MAY 1998 – REVISED APRIL 2013 DS3487 Quad TRI-STATE Line Driver Check for Samples: DS3487 FEATURES DESCRIPTION • • • • • • • The DS3487 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. 1 2 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 Figure 1.
