LM2903VQPWR

Texas Instruments · Comparators · TSSOP-8

LM2903VQPWR 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 tri_state Output of comparator 1 with open-drain configuration that sinks up to 20mA when the inverting input (1IN-) exceeds the non-inverting input (1IN+).
2 1IN− input Inverting input of comparator 1 accepting voltages from 0V to VCC-2V with maximum input bias current of 250nA.
3 1IN+ input Non-inverting input of comparator 1 accepting voltages from 0V to VCC-2V with maximum input bias current of 250nA.
4 GND power_in Ground reference at 0V potential.
5 2IN+ input Non-inverting input of comparator 2 accepting voltages from 0V to VCC-2V with maximum input bias current of 250nA.
6 2IN- input Inverting input of comparator 2 accepting voltages from 0V to VCC-2V with maximum input bias current of 250nA.
7 2OUT tri_state Output of comparator 2 with open-drain configuration that sinks up to 20mA when the inverting input (2IN-) exceeds the non-inverting input (2IN+).
8 VCC power_in Positive power supply for the device with operating voltage range from 2V to 32V and maximum total supply current of 2.5mA.
