RS393XK-Q1

Jiangsu RUNIC Tech · Comparators · SOIC-8

RS393XK-Q1 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 Channel A open-drain output, which needs an external pull-up resistor to the logic supply and has a short-circuit duration limit of 10 s to V- or V+.
2 -INA input Inverting input of channel A; input pin voltage is rated (V-)-0.3 V to (V+)+0.3 V, and input signals swinging more than 0.3 V beyond the rails should be limited to ±10 mA.
3 +INA input Noninverting input of channel A; input common-mode range is (V-)-0.1 V to (V+)+0.1 V over the full temperature range, with the same ±10 mA current limit beyond the rails.
4 V- power_in Negative (lowest) power supply pin; single-supply operation is referenced to this pin, with the total supply (V+) - (V-) rated 1.8 V to 5.5 V.
5 +INB input Noninverting input of channel B; input common-mode range is (V-)-0.1 V to (V+)+0.1 V over the full temperature range, with the same ±10 mA current limit beyond the rails.
6 -INB input Inverting input of channel B; input pin voltage is rated (V-)-0.3 V to (V+)+0.3 V, and input signals swinging more than 0.3 V beyond the rails should be limited to ±10 mA.
7 OUTB output Channel B open-drain output, which needs an external pull-up resistor to the logic supply and has a short-circuit duration limit of 10 s to V- or V+.
8 V+ power_in Positive (highest) power supply pin; the supply is rated 1.8 V to 5.5 V single-supply, with absolute maximum supply voltage of 7 V.
