LM393BIDR

Texas Instruments · Comparators · SOIC-8

LM393BIDR from Texas Instruments, in a SOIC-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 a positive supply (typically 2 kΩ to 10 kΩ). Output sinks up to 16 mA when active low.
2 1IN- input Comparator 1 inverting input. Common-mode voltage range extends from V- to (V+ - 2 V). Input bias current typically 15 nA.
3 1IN+ input Comparator 1 non-inverting input. Common-mode voltage range extends from V- to (V+ - 2 V). Input bias current typically 15 nA.
4 GND power_in Negative supply / ground pin (V-). Connect to system ground in single-supply operation, or to the negative rail in split-supply operation.
5 2IN+ input Comparator 2 non-inverting input. Common-mode voltage range extends from V- to (V+ - 2 V). Input bias current typically 15 nA.
6 2IN- input Comparator 2 inverting input. Common-mode voltage range extends from V- to (V+ - 2 V). Input bias current typically 15 nA.
7 2OUT output Comparator 2 open-collector output. Requires an external pull-up resistor to a positive supply (typically 2 kΩ to 10 kΩ). Output sinks up to 16 mA when active low.
8 VCC power_in Positive supply pin (V+). Accepts 2.7 V to 36 V single-supply, or ±1.35 V to ±18 V split-supply operation. Bypass with 0.1 µF ceramic to GND close to the pin.
