TL331BIDBVR

Texas Instruments · Comparators · SOT-23-5

TL331BIDBVR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN- input Negative input terminal for voltage comparison; common-mode input voltage range 0V to VCC-1.5V
2 GND power_in Ground reference
3 IN+ input Positive input terminal for voltage comparison; common-mode input voltage range 0V to VCC-1.5V
4 OUT output Open-collector output that sinks maximum 20mA when IN- exceeds IN+ plus input offset voltage
5 VCC power_in Positive power supply input; operating voltage range 2V to 36V for TL331B and TL391B
