HD26LS31
Quadruple Differential Line Drivers With 3 State Outputs
ADE-205-576 (Z)
1st. Edition
Dec. 2000
Description
The HD26LS31 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 40 mA.
