L6374FP013TR STMicroelectronics

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 SO-20 Push-pull outputs with three state control and true zero current between Vs and ground Current limiting on each output effective in the Description fullground to V output voltage range The L6374 is especially designed to be used as a Output voltage clamp to Vs and to ground line driver in industrial control systems based on Overtemperature and undervoltage protections the 24 V signal levels (IEC 61131, 24VDC). Diagnostic for overtemperature, undervoltage Table 1.
