TLV3491AIDBVR

Texas Instruments · Comparators · SOT-23-5

TLV3491AIDBVR 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 OUT output Push-pull comparator output. Drives rail-to-rail with typical output current capability suitable for direct logic interfacing.
2 V- power_in Negative supply / ground. Connect to system ground for single-supply operation (2.5V to 5.5V total supply).
3 IN+ input Non-inverting comparator input. Rail-to-rail input range extends 200mV beyond both supply rails.
4 IN- input Inverting comparator input. Rail-to-rail input range extends 200mV beyond both supply rails.
5 V+ power_in Positive supply pin. Operating range 2.5V to 5.5V (single supply) or ±1.25V to ±2.75V (dual supply). Quiescent current typically 1.2µA.
