| 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 x 40 x 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.

All typical values are at V CC = 5 V, Ta = 25C. 2. |VOD| and |V OC | are the changes in magnitudes of VOD and VOC , respectively, that occur when the input is changed from a high level to a low level. 3. In EIA standard RS-422A, VOC , which is the average of the two output voltages with respect to ground, is called output offset voltage, VOS. 4. Only one output should be shorted at a time, and duration of the short circuit should not exceed one second. 3 HD75159 50 VOD 2 50 VOC Note: 1. Differential and common mode output voltages.
