LM2903BIPWR

Texas Instruments · Comparators · TSSOP-8

LM2903BIPWR 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 Comparator 1 open-drain output sinking up to 25mA when 1IN- exceeds 1IN+ plus input offset voltage.
2 1IN- input Comparator 1 inverting input; common-mode voltage range 0V to VCC-2V; maximum differential input voltage ±38V.
3 1IN+ input Comparator 1 non-inverting input; common-mode voltage range 0V to VCC-2V; maximum differential input voltage ±38V.
4 GND power_in Ground and negative supply reference connection.
5 2IN+ input Comparator 2 non-inverting input; common-mode voltage range 0V to VCC-2V; maximum differential input voltage ±38V.
6 2IN- input Comparator 2 inverting input; common-mode voltage range 0V to VCC-2V; maximum differential input voltage ±38V.
7 2OUT output Comparator 2 open-drain output sinking up to 25mA when 2IN- exceeds 2IN+ plus input offset voltage.
8 VCC power_in Positive supply voltage; operating range 2V to 36V; total supply current 0.6-0.8mA at 5V-36V.
