TL331IDBVRQ1

Texas Instruments · Comparators · SOT-23-5

TL331IDBVRQ1 from Texas Instruments, in a SOT-23-5. 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 IN- input Negative input of the comparator; input voltage range is -0.3 V to 36 V (38 V for B versions) and the common-mode range extends from ground to VCC - 1.5 V.
2 GND power_in Ground.
3 IN+ input Positive input of the comparator; input voltage range is -0.3 V to 36 V (38 V for B versions) and the common-mode range extends from ground to VCC - 1.5 V.
4 OUT output Open-collector/drain output that sinks current when IN- is higher than IN+, with output current up to 20 mA and output voltage up to 36 V (38 V for B versions).
5 VCC power_in Power supply input, operating from 2 V to 36 V.
