CD74HC08E

Texas Instruments · Gates · PDIP-14

CD74HC08E from Texas Instruments, in a PDIP-14. 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 1A input Input channel 1, input A of the first 2-input AND gate, a high-impedance standard CMOS input whose edges must be fast to avoid excess current and oscillation.
2 1B input Input channel 1, input B of the first 2-input AND gate, a high-impedance standard CMOS input whose edges must be fast to avoid excess current and oscillation.
3 1Y output Output channel 1, output Y of the first AND gate, a balanced CMOS push-pull output implementing Y = A AND B.
4 2A input Input channel 2, input A of the second 2-input AND gate, a high-impedance standard CMOS input whose edges must be fast to avoid excess current and oscillation.
5 2B input Input channel 2, input B of the second 2-input AND gate, a high-impedance standard CMOS input whose edges must be fast to avoid excess current and oscillation.
6 2Y output Output channel 2, output Y of the second AND gate, a balanced CMOS push-pull output implementing Y = A AND B.
7 GND power_in Ground reference for the device, which must not be exceeded by the continuous current limit of ±50 mA through VCC or GND.
8 3Y output Output channel 3, output Y of the third AND gate, a balanced CMOS push-pull output implementing Y = A AND B.
9 3A input Input channel 3, input A of the third 2-input AND gate, a high-impedance standard CMOS input whose edges must be fast to avoid excess current and oscillation.
10 3B input Input channel 3, input B of the third 2-input AND gate, a high-impedance standard CMOS input whose edges must be fast to avoid excess current and oscillation.
11 4Y output Output channel 4, output Y of the fourth AND gate, a balanced CMOS push-pull output implementing Y = A AND B.
12 4A input Input channel 4, input A of the fourth 2-input AND gate, a high-impedance standard CMOS input whose edges must be fast to avoid excess current and oscillation.
13 4B input Input channel 4, input B of the fourth 2-input AND gate, a high-impedance standard CMOS input whose edges must be fast to avoid excess current and oscillation.
14 VCC power_in Positive supply, specified from 2 V to 6 V in the Recommended Operating Conditions, with a 0.1-μF bypass capacitor recommended.
