U6805B
Hex-Driver with Thermal Monitoring
Description
The hex-driver IC includes 6 non-inverted and current
limited output stages with an open collector. Common
thermal shutdown protects outputs against critical
junction temperature.
Each output can sink 20 mA, parallel output operation is
possible. The digital inputs have Schmitt-trigger function
with pull-up current sources to 5 V.
