LM393N

Texas Instruments · Comparators · PDIP-8

LM393N from Texas Instruments, in a PDIP-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 OUTA output Output of comparator channel A; the output logic levels are compatible with TTL, DTL, ECL, MOS and CMOS logic systems, with low saturation voltage of 250 mV at 4 mA.
2 -INA input Inverting input of comparator channel A; the common-mode input range includes ground, and the low input voltage must not go below -0.3 V.
3 +INA input Noninverting input of comparator channel A; the common-mode input range includes ground, and the low input voltage must not go below -0.3 V.
4 GND power_in Ground (0 V) reference pin for the device.
5 +INB input Noninverting input of comparator channel B; the common-mode input range includes ground, and the low input voltage must not go below -0.3 V.
6 -INB input Inverting input of comparator channel B; the common-mode input range includes ground, and the low input voltage must not go below -0.3 V.
7 OUTB output Output of comparator channel B; the output logic levels are compatible with TTL, DTL, ECL, MOS and CMOS logic systems, with low saturation voltage of 250 mV at 4 mA.
8 V+ power_in Positive power supply; 2.0 V to 36 V single supply or ±1.0 V to ±18 V dual supply per the recommended operating conditions.
