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 utilize 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 to ensure the
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 optimum performance when used with the MC3486 quadruple line receiver. It is
supplied in a 16-pin dual-in-line package and operates from a single 5-V supply.
