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.
