HD29412
Dual Differential Line Drivers With 3 State Outputs The HD29412 features dual differential line drivers with three state outputs designed to satisfy the requirements of EIA–422. Each driver has an output control is low, the associated outputs are in a high impedance state. This permits many deviced to be connected together on the same transmission line for party line applications.
