L6374_08 Datasheet, PDF (1/19 Pages) STMicroelectronics – Industrial quad line driver

L6374
Industrial quad line driver
Features
■ Four independent line drivers with 100 mA up
to 35 V outputs
■ Input signals between - 7 V and + 35 V, with
pre-setting threshold
■ Push-pull outputs with three state control and
true zero current between Vs and ground
■ Current limiting on each output effective in the
full "ground to Vs" output voltage range
■ Output voltage clamp to Vs and to ground
■ Overtemperature and undervoltage protections
■ Diagnostic for overtemperature, undervoltage
and overcurrent
■ Pre-setting delay for overcurrent diagnostic
■ High speed operation: up to 300 kHz with 35 V
