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.
