1 / 16 page MC3487 QUADRUPLE DIFFERENTIAL LINE DRIVER SLLS098C − MAY 1980 − REVISED FEBRUARY 2004 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Meets or Exceeds Requirements of ANSI TIA/EIA-422-B and ITU Recommendation V.11 D 3-State, TTL-Compatible Outputs D Fast Transition Times D High-Impedance Inputs D Single 5-V Supply D Power-Up and Power-Down Protection description/ordering information 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.
