LM2903BQDGKRQ1

Texas Instruments · Comparators · VSSOP-8

LM2903BQDGKRQ1 from Texas Instruments, in a VSSOP-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 1OUT output Output of comparator 1; open-drain NPN output capable of sinking up to 25mA.
2 1IN- input Inverting input of comparator 1; accepts input voltage from -0.1V to (VCC-2V).
3 1IN+ input Non-inverting input of comparator 1; accepts input voltage from -0.1V to (VCC-2V).
4 GND power_in Ground; common reference for power supply and signal return.
5 2IN+ input Non-inverting input of comparator 2; accepts input voltage from -0.1V to (VCC-2V).
6 2IN- input Inverting input of comparator 2; accepts input voltage from -0.1V to (VCC-2V).
7 2OUT output Output of comparator 2; open-drain NPN output capable of sinking up to 25mA.
8 VCC power_in Positive supply voltage; operating range 2V to 36V.
