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.
