HD75159
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.
