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
swing
Description
The L6374 is especially designed to be used as a
line driver in industrial control systems based on
the 24 V signal levels (IEC 61131, 24VDC).
