Quadruple Differential Line Driver

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.
