LM293QT

STMicroelectronics · Comparators · DFN-8(2x2)

LM293QT from STMicroelectronics, in a DFN-8(2x2). 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 Out1 output Output of first comparator; accepts sink current up to 20 mA with low output saturation voltage 80 mV typical at Isink = 4 mA, TTL/MOS/CMOS compatible.
2 In1- input Inverting input of first comparator; input bias current 20 nA typical, common-mode voltage range 0 to (VCC+) - 1.5 V.
3 In1+ input Non-inverting input of first comparator; input bias current 20 nA typical, common-mode voltage range 0 to (VCC+) - 1.5 V.
4 Vcc- power_in Negative power supply; voltage range -0.3 V to Vcc+ + 0.3 V; combined with Vcc+ provides 2 to 36 V supply voltage.
5 In2+ input Non-inverting input of second comparator; input bias current 20 nA typical, common-mode voltage range 0 to (VCC+) - 1.5 V.
6 In2- input Inverting input of second comparator; input bias current 20 nA typical, common-mode voltage range 0 to (VCC+) - 1.5 V.
7 Out2 output Output of second comparator; accepts sink current up to 20 mA with low output saturation voltage 80 mV typical at Isink = 4 mA, TTL/MOS/CMOS compatible.
8 Vcc+ power_in Positive power supply; voltage range ±18 V or 36 V single supply; combined with Vcc- provides 2 to 36 V supply voltage.
