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.

•

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
