LM2903QPWRG4Q1

Texas Instruments · Comparators · TSSOP-8

LM2903QPWRG4Q1 from Texas Instruments, in a TSSOP-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; the datasheet notes outputs are TTL, MOS and CMOS compatible and may be connected to other open-collector outputs.
2 1IN- input Negative (inverting) input of comparator 1; for the LM2903-Q1 the input voltage range (either input) is -0.3 V to 36 V.
3 1IN+ input Positive (non-inverting) input of comparator 1; the common-mode input voltage range includes ground.
4 GND power_in Ground reference pin; all voltages except differential voltages are referenced to GND.
5 2IN+ input Positive (non-inverting) input of comparator 2; the common-mode input voltage range includes ground.
6 2IN- input Negative (inverting) input of comparator 2; for the LM2903-Q1 the input voltage range (either input) is -0.3 V to 36 V.
7 2OUT output Output of comparator 2; the datasheet notes outputs are TTL, MOS and CMOS compatible and may be connected to other open-collector outputs.
8 VCC power_in Positive supply pin; for the LM2903-Q1 the absolute maximum supply voltage is 36 V (32 V for the LM2903E-Q1) with respect to GND.
