RS393XM

Jiangsu RUNIC Tech · Comparators · MSOP-8

RS393XM from Jiangsu RUNIC Tech, in a MSOP-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; it needs an external pull-up resistor to reach a logic-high level, and its output saturation voltage is typically 150 mV.
2 -INA input Channel A inverting input; the common-mode voltage range is (V-)-0.1 V to (V+)+0.1 V over -40°C to 125°C, and input signals beyond 0.3 V outside the supply rails should be current-limited to ±10 mA or less.
3 +INA input Channel A noninverting input; the common-mode voltage range is (V-)-0.1 V to (V+)+0.1 V over -40°C to 125°C, and input signals beyond 0.3 V outside the supply rails should be current-limited to ±10 mA or less.
4 V- power_in Negative (lowest) power supply; for single-supply use the device operates from 1.8 V to 5.5 V between V+ and V-, or from ±0.9 V to ±2.75 V in dual-supply configuration.
5 +INB input Channel B noninverting input; the common-mode voltage range is (V-)-0.1 V to (V+)+0.1 V over -40°C to 125°C, and input signals beyond 0.3 V outside the supply rails should be current-limited to ±10 mA or less.
6 -INB input Channel B inverting input; the common-mode voltage range is (V-)-0.1 V to (V+)+0.1 V over -40°C to 125°C, and input signals beyond 0.3 V outside the supply rails should be current-limited to ±10 mA or less.
7 OUTB output Channel B open-drain output; it needs an external pull-up resistor to reach a logic-high level, and its output saturation voltage is typically 150 mV.
8 V+ power_in Positive (highest) power supply; the device operates from 1.8 V to 5.5 V single-supply, with absolute maximum supply voltage of 7 V.
