HD75159 Dual Differential Line Drivers With 3 State Outputs ADE-205-589 (Z) 1st. Edition Dec. 2000 Description The HD75159 features dual differential line drivers with three state outputs, which satisfy the requirements of EIA(standard) RS-422A. Each driver has an output control. When the output control is low, the associated outputs are in a high impedance state. This permits many devices to be connected together on the same transmission line for party line applications.

The above date were taken by the ∆V BE method, mounting on a glass epoxy board (40 × 40 × 1.6 mm) of 10 % wiring density. 2. The absolute maximum ratings are values which must not individually be exceeded, and furthermore, no two of which may be realized at the same time.
