General Description

The MM74HC08 AND gates utilize advanced silicon­gate CMOS technology to achieve operating speeds
similar to LS-TTL gates with the low power consumption
of standard CMOS integrated circuits. The HC08 has
buffered outputs, providing high noise immunity and the
ability to drive 10 LS-TTL loads. The 74HC logic family is
functionally as well as pin-out compatible with the stan­dard 74LS logic family. All inputs are protected from
damage due to static discharge by internal diode clamps
to V

and ground.

Absolute Maximum Ratings

(1)

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
