TS3021AILT

STMicroelectronics · Comparators · SOT-23-5

TS3021AILT from STMicroelectronics, 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 digital output. Swings rail-to-rail between VCC+ and VCC-. Drives CMOS/TTL logic levels; typical propagation delay ~38 ns.
2 VCC- power_in Negative supply rail. Tie to GND for single-supply operation, or to a negative rail for split-supply operation. VCC+ − VCC- must be between 2.2 V and 5.5 V.
3 IN+ input Non-inverting analog comparator input. Rail-to-rail input common-mode range (extends 200 mV beyond each supply rail). When V(IN+) > V(IN-), OUT is driven high.
4 IN- input Inverting analog comparator input. Rail-to-rail input common-mode range. When V(IN-) > V(IN+), OUT is driven low.
5 VCC+ power_in Positive supply rail, 2.2 V to 5.5 V referenced to VCC-. Decouple with a 100 nF ceramic capacitor to VCC- placed close to the device.
