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). |
