HD29412

HD29412 Dual Differential Line Drivers With 3 State Output ADE-205-581 (Z) 1st. Edition Dec. 2000 Description 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.
