† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

Description

The MC3487 offers four independent differential line drivers designed to meet the specifications of ANSI EIA/TIA-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 of MC3487 is provided to ensure a high-impedance state at the differential outputs during power-up and power-down transition times provided the output enable is low. The outputs are capable of source or sink currents of 48 mA.

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.

The MC3487 is characterized for operation from 0°C to 70°C.
