CD74HC366QDRQ1

Texas Instruments · Buffers, Drivers, Receivers, Transceivers · SOIC-16

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.
