Dual Differential Line Drivers / ReceiversWith 3 State Outputs
The HD29050 features differential line drivers /
receivers with three state output designed to meet
the spec of EIA RS – 422A and 423A. Each device
has two drivers / receivers in a 16 pin package.
The device becomes in enable state when active
high for a driver and active low for a receiver.
Features

Notes: 1. Not more than one output should be shorted at a time, and duration of the short circuit should
not exceed one second.
2. In this table, only the threshold voltage is expressed in algebra.
3. All typical values are at V CC = 5 V, Ta = 25°C.
