CD74HC366QDRQ1 from Texas Instruments, in a SOIC-16. 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 | OE1 | input | Active-low three-state output enable 1, NORed with OE2 to control all six gates; outputs are high-impedance when OE1 is high. |
| 2 | 1A | input | Buffer channel 1 data input; must not be left floating. |
| 3 | 1Y | output | Channel 1 three-state inverting output (1Y̅ on HC366), high-current bus driver able to drive up to 15 LSTTL loads. |
| 4 | 2A | input | Buffer channel 2 data input; must not be left floating. |
| 5 | 2Y | output | Channel 2 three-state inverting output (2Y̅ on HC366), high-current bus driver able to drive up to 15 LSTTL loads. |
| 6 | 3A | input | Buffer channel 3 data input; must not be left floating. |
| 7 | 3Y | output | Channel 3 three-state inverting output (3Y̅ on HC366), high-current bus driver able to drive up to 15 LSTTL loads. |
| 8 | GND | power_in | Ground pin. |
| 9 | 4Y | output | Channel 4 three-state inverting output (4Y̅ on HC366), high-current bus driver able to drive up to 15 LSTTL loads. |
| 10 | 4A | input | Buffer channel 4 data input; must not be left floating. |
| 11 | 5Y | output | Channel 5 three-state inverting output (5Y̅ on HC366), high-current bus driver able to drive up to 15 LSTTL loads. |
| 12 | 5A | input | Buffer channel 5 data input; must not be left floating. |
| 13 | 6Y | output | Channel 6 three-state inverting output (6Y̅ on HC366), high-current bus driver able to drive up to 15 LSTTL loads. |
| 14 | 6A | input | Buffer channel 6 data input; must not be left floating. |
| 15 | OE2 | input | Active-low three-state output enable 2, NORed with OE1 to control all six gates; outputs are high-impedance when OE2 is high. |
| 16 | VCC | power_in | Positive supply, 2 V to 6 V for HC types (absolute maximum 7 V); a 0.1-µF bypass capacitor is recommended close to the pin. |
