CAHCT1G32QDBVRQ1

Texas Instruments · Gates · SOT-23-5

CAHCT1G32QDBVRQ1 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 A input Input A of the 2-input positive-OR gate, a TTL-compatible input that must be held at VCC or GND if unused.
2 B input Input B of the 2-input positive-OR gate, a TTL-compatible input that must be held at VCC or GND if unused.
3 GND power_in Ground pin.
4 Y output Output Y of the OR gate (Y = A + B), with ±8 mA drive at 4.5 V to 5.5 V supply.
5 VCC power_in Power pin, supply voltage 4.5 V to 5.5 V recommended (absolute maximum 7 V).
