LM393DRG

HANSCHIP semiconductor · Comparators · SOP-8

LM393DRG from HANSCHIP semiconductor, in a SOP-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 1OUT output Comparator 1 open-collector output. Requires an external pull-up resistor to VCC (typ. 1 kΩ-100 kΩ). Sinks up to ~16 mA when the output is low.
2 1IN- input Comparator 1 inverting input. When V(1IN-) > V(1IN+), the open-collector output pulls low.
3 1IN+ input Comparator 1 non-inverting input. Common-mode input range extends from GND to VCC−1.5 V.
4 GND power_in Negative supply / ground reference. Tied to system ground in single-supply operation, or to V- in split-supply operation.
5 2IN+ input Comparator 2 non-inverting input. Common-mode input range extends from GND to VCC−1.5 V.
6 2IN- input Comparator 2 inverting input. When V(2IN-) > V(2IN+), the open-collector output pulls low.
7 2OUT output Comparator 2 open-collector output. Requires an external pull-up resistor to VCC. Sinks up to ~16 mA when low.
8 VCC power_in Positive supply pin. Single-supply range 2 V to 36 V, or split-supply ±1 V to ±18 V. Decouple with a 0.1 µF ceramic capacitor to GND.
