TLV3502AQDCNRQ1

Texas Instruments · Comparators · SOT-23-8

TLV3502AQDCNRQ1 from Texas Instruments, in a SOT-23-8. 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 A input Non-inverting input of comparator channel A; the common-mode range extends beyond the rails, from (V−) − 0.2 V to (V+) + 0.2 V.
2 -IN A input Inverting input of comparator channel A; the common-mode range extends beyond the rails, from (V−) − 0.2 V to (V+) + 0.2 V.
3 +IN B input Non-inverting input of comparator channel B; the common-mode range extends beyond the rails, from (V−) − 0.2 V to (V+) + 0.2 V.
4 -IN B input Inverting input of comparator channel B; the common-mode range extends beyond the rails, from (V−) − 0.2 V to (V+) + 0.2 V.
5 V- power_in Negative (lowest) power supply pin; the device is specified for a 2.7 V to 5.5 V supply.
6 OUT B output Push-pull CMOS output of comparator channel B, rail-to-rail, able to drive CMOS or TTL logic directly.
7 OUT A output Push-pull CMOS output of comparator channel A, rail-to-rail, able to drive CMOS or TTL logic directly.
8 V+ power_in Positive (highest) power supply pin; absolute maximum supply voltage is 5.5 V.
