3 Description

The MC3487 offers four independent differential line

drivers designed to meet the specifications of ANSI

TIA/EIA-422-B and ITU Recommendation V.11. Each

driver has a TTL compatible input buffered to reduce

current and minimize loading.

The driver outputs uses 3-state circuitry to provide

high-impedance states at any pair of differential

outputs when the appropriate output enable is at a

low logic level. Internal circuitry is provided a high-

impedance state at the differential outputs during

power-up and power-down transition times, provided

the output enable is low.

The MC3487 is designed for best performance when

used with the MC3486 quadruple line receiver. The

device is available in a 16-pin dual-in-line package

and operates from a single 5V supply.
