LM393AM

HGSEMI · Comparators · SOP-8

LM393AM from HGSEMI, in a SOP-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 OUT1 output Comparator 1 open-collector output; can be wired-AND with other open-collector outputs, low-level output voltage 150 mV typ at IOL=4mA.
2 IN1- input Comparator 1 inverting input; common-mode range 0 to Vcc-1.5V at 25°C and must not go negative by more than 0.3V.
3 IN1+ input Comparator 1 non-inverting input; common-mode range 0 to Vcc-1.5V at 25°C and may go to 30V without damage.
4 GND power_in Ground; input common-mode range includes GND, and split supplies are also possible.
5 IN2+ input Comparator 2 non-inverting input; common-mode range 0 to Vcc-1.5V at 25°C and may go to 30V without damage.
6 IN2- input Comparator 2 inverting input; common-mode range 0 to Vcc-1.5V at 25°C and must not go negative by more than 0.3V.
7 OUT2 output Comparator 2 open-collector output; can be wired-AND with other open-collector outputs, low-level output voltage 150 mV typ at IOL=4mA.
8 VCC power_in Positive supply; operates over a wide single-supply range with datasheet specs at 5V to 30V and supply current 0.8 mA typ at 5V.
