Jiangsu RUNIC Tech · Comparators · TSSOP-14

RS339XQ from Jiangsu RUNIC Tech, in a TSSOP-14. 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 OUTB output Channel B open-drain comparator output, which needs an external pull-up resistor to a logic voltage (VOH up to 5.6 V).
2 OUTA output Channel A open-drain comparator output, which needs an external pull-up resistor to a logic voltage (VOH up to 5.6 V).
3 V+ power_in Positive (highest) power supply; single-supply operation is specified from 1.8 V to 5.5 V.
4 -INA input Inverting input of channel A; absolute maximum input range is (V-)-0.3 V to (V+)+0.3 V.
5 +INA input Noninverting input of channel A; common-mode range is (V-)-0.1 V to (V+)+0.1 V over -40 °C to 125 °C.
6 -INB input Inverting input of channel B; absolute maximum input range is (V-)-0.3 V to (V+)+0.3 V.
7 +INB input Noninverting input of channel B; common-mode range is (V-)-0.1 V to (V+)+0.1 V over -40 °C to 125 °C.
8 -INC input Inverting input of channel C; absolute maximum input range is (V-)-0.3 V to (V+)+0.3 V.
9 +INC input Noninverting input of channel C; common-mode range is (V-)-0.1 V to (V+)+0.1 V over -40 °C to 125 °C.
10 -IND input Inverting input of channel D; absolute maximum input range is (V-)-0.3 V to (V+)+0.3 V.
11 +IND input Noninverting input of channel D; common-mode range is (V-)-0.1 V to (V+)+0.1 V over -40 °C to 125 °C.
12 V- power_in Negative (lowest) power supply; the datasheet specifies single supply 1.8 V to 5.5 V or dual supply ±0.9 V to ±2.75 V.
13 OUTD output Channel D open-drain comparator output, which needs an external pull-up resistor to a logic voltage (VOH up to 5.6 V).
14 OUTC output Channel C open-drain comparator output, which needs an external pull-up resistor to a logic voltage (VOH up to 5.6 V).
