Dual Differential Line Drivers / ReceiversWith 3 State Outputs

The HD29051 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
Driver
• Built in current restriction when short circuit
• Power up / down protection.
• High output current IOH = –40 mA
                                  IOL = 40 mA

Receiver
• Input hysteresis (Typ. 50 mV)
• In phase input voltage ±200 mV of input sensitivity in the range –7 to +12 V.
