描述 Description

The HD26C31 features quadruple differential line drivers which satisfy the requirements of EIA standard

RS-422A. This device is designed to provide differential signals with high current capability on bus lines.

The circuit provides enable input to control all four drivers. The output circuit has active pull up and pull

down and is capable of sinking or sourcing 20 mA.
