LM393MM

HGSEMI · Comparators · MSOP-8

LM393MM from HGSEMI, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1OUT output Channel 1 open-drain output; output saturation voltage typically 0.1V at IOL=4mA.
2 1IN- input Channel 1 inverting input; common-mode range -0.3V to VCC, differential input up to ±18V absolute maximum.
3 1IN+ input Channel 1 non-inverting input; common-mode range -0.3V to VCC, differential input up to ±18V absolute maximum.
4 VEE power_in Negative supply, ground in single-supply operation; dual-supply operation is up to ±16V.
5 2IN+ input Channel 2 non-inverting input; common-mode range -0.3V to VCC, differential input up to ±18V absolute maximum.
6 2IN- input Channel 2 inverting input; common-mode range -0.3V to VCC, differential input up to ±18V absolute maximum.
7 2OUT output Channel 2 open-drain output; output saturation voltage typically 0.1V at IOL=4mA.
8 VCC power_in Positive supply, 2V to 32V single-supply operation (36V absolute maximum).
