Features
1. Description
The triple driver IC includes three non-inverted and current-limited output stages with
an open collector. Common thermal shutdown protects the outputs against critical
junction temperatures. Each output can sink a current of 20 mA, parallel output opera-
tion is possible. The digital inputs have Schmitt-trigger function with pull-up resistors
to 5 V.
