LM393XK

Jiangsu RUNIC Tech · Comparators · SOIC-8

LM393XK from Jiangsu RUNIC Tech, in a SOIC-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 Open-drain output of channel A, with signal output limited to (V-)-0.3 V to (V+)+0.3 V and ±55 mA per the absolute maximum ratings.
2 -INA input Inverting input of channel A, with input pin voltage limited to (V-)-0.3 V to (V+)+0.3 V and input current limited to ±10 mA.
3 +INA input Noninverting input of channel A, with input pin voltage limited to (V-)-0.3 V to (V+)+0.3 V and input current limited to ±10 mA.
4 V- power_in Negative (lowest) power supply pin; single-supply operation is specified from 3 V to 36 V between V+ and V-.
5 +INB input Noninverting input of channel B, with input pin voltage limited to (V-)-0.3 V to (V+)+0.3 V and input current limited to ±10 mA.
6 -INB input Inverting input of channel B, with input pin voltage limited to (V-)-0.3 V to (V+)+0.3 V and input current limited to ±10 mA.
7 OUTB output Open-drain output of channel B, with signal output limited to (V-)-0.3 V to (V+)+0.3 V and ±55 mA per the absolute maximum ratings.
8 V+ power_in Positive (highest) power supply pin; the supply voltage (V+)-(V-) is rated up to 36 V absolute maximum.
