Texas Instruments · Comparators · SOT-23-5

TL331KDBVR 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 Inverting (negative) comparator input. Common-mode range extends from 0 V to VCC - 1.5 V; input bias current typ 25 nA. Differential input range up to +/-36 V.
2 GND power_in Device ground / negative supply (VCC-). Tied to system ground for single-supply operation, or to a negative rail for dual-supply operation.
3 IN+ input Non-inverting (positive) comparator input. Common-mode range extends from 0 V to VCC - 1.5 V; input bias current typ 25 nA. Differential input range up to +/-36 V.
4 OUT output Open collector/drain comparator output. Requires an external pull-up resistor to logic supply (up to 36 V). Sinks up to 6 mA (typ) with VOL <= 400 mV at IOL = 4 mA; supports wired-AND.
5 VCC power_in Positive supply input, 2 V to 36 V. Supply current independent of supply voltage, typ 0.4 mA (max 0.7 mA at VCC = 5 V).
