Quad 2-Input AND Gate
High-Speed Silicon-Gate CMOS
The IN74AC08 is identical in pinout to the LS/ALS08,
HC/HCT08. The device inputs are compatible with standard CMOS
outputs; with pullup resistors, they are compatible with LS/ALS
outputs.

This device contains protection circuitry to guard against damage due to high static voltages or electric
fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated
voltages to this high-impedance circuit. For proper operation, V

OUT
should be constrained to the range
