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.

Notes: 1. All typical values are at VCC = 5 V, Ta = 25°C.
2. ∆ |VOD| and ∆ |VOC| 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.
