LM393ADT

STMicroelectronics · Comparators · SO-8

LM393ADT from STMicroelectronics, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT1 output Comparator 1 open-collector output; VOL = 80 mV typ at Isink = 4 mA; sink current 6 mA typ / 18 mA max (VCC = 5 V, Vid = 1 V, Vo = 1.5 V); high-level output leakage IOH = 0.1 nA typ at VCC = Vo = 30 V.
2 IN1- input Comparator 1 inverting (−) input; common-mode range 0 V to (VCC+) − 1.5 V; input bias current 20 nA typ / 250 nA max; input offset current ±3 nA typ / ±50 nA max.
3 IN1+ input Comparator 1 non-inverting (+) input; common-mode range 0 V to (VCC+) − 1.5 V; input bias current 20 nA typ / 250 nA max; input offset voltage ±1 mV typ / ±5 mV max.
4 VCC- power_in Negative supply rail or ground; 0 V in single-supply operation; dual-supply range down to −18 V; differential supply (VCC+) − (VCC−) must be 2 V to 36 V.
5 IN2+ input Comparator 2 non-inverting (+) input; common-mode range 0 V to (VCC+) − 1.5 V; input bias current 20 nA typ / 250 nA max; input offset voltage ±1 mV typ / ±5 mV max.
6 IN2- input Comparator 2 inverting (−) input; common-mode range 0 V to (VCC+) − 1.5 V; input bias current 20 nA typ / 250 nA max; input offset current ±3 nA typ / ±50 nA max.
7 OUT2 output Comparator 2 open-collector output; VOL = 80 mV typ at Isink = 4 mA; sink current 6 mA typ / 18 mA max (VCC = 5 V, Vid = 1 V, Vo = 1.5 V); high-level output leakage IOH = 0.1 nA typ at VCC = Vo = 30 V.
8 VCC+ power_in Positive supply rail; single-supply range 2 V to 36 V, dual-supply up to +18 V; total ICC = 0.45 mA typ / 1 mA max at VCC = 5 V, no load.
