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.
