MM54HC51/MM74HC51 Dual AND-OR-Invert Gate
MM54HC58/MM74HC58 Dual AND-OR Gate
General Description
These gates utilize advanced silicon-gate CMOS technology
to achieve operating speeds similar to LS-TTL gates with
the low power consumption of standard CMOS integrated
circuits. All gates have buffered outputs, providing high
noise immunity and the ability to drive 10 LS-TTL loads. The
54HC/74HC logic family is functionally as well as pin-out
compatible with the standard 54LS/74LS logic family. All
inputs are protected from damage due to static discharge by
internal diode clamps to VCC and ground.
