HD29050 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.

All voltage values except for differential input voltage are with respect to network ground terminal. 2. Differential input voltage is measured at the noninverting input with respect to the corresponding inverting input. 3. Only receiver 4. Only driver 5. Z state 6. The absolute maximum ratings are values which must not individually be exceeded, and furthermore, no two of which may be realized at t [ ... ]
