CAHCT1G08QDBVRQ1 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 AND gate (Y = A × B), TTL-compatible CMOS input with VIH min 2.00 V and VIL max 0.8 V; must not be left floating. |
| 2 | B | input | Input B of the 2-input positive AND gate (Y = A × B), TTL-compatible CMOS input with VIH min 2.00 V and VIL max 0.8 V; must not be left floating. |
| 3 | GND | power_in | Ground pin. |
| 4 | Y | output | Output Y of the AND gate, balanced CMOS push-pull output with ±8 mA drive at 5 V. |
| 5 | VCC | power_in | Positive supply pin, recommended operating range 4.5 V to 5.5 V (absolute maximum 7 V), with a 0.1 µF bypass capacitor recommended close to the pin. |
