$3.95

Genuine vintage National Semiconductor MM74HC08N / MC74HC08N high-speed CMOS logic integrated circuit in a 14-pin through-hole DIP package. Multiple matching ICs may be shown in the product photographs because more than one piece is available. THIS LISTING AND PRICE ARE FOR ONE (1) IC; quantity purchased determines the number of individual ICs supplied.

This device contains four independent 2-input AND gates and belongs to the widely used 74HC logic family. The MM74HC08 operates from approximately 2V to 6V and was designed to provide logic speeds comparable to LS-TTL while retaining the low power consumption and high noise immunity associated with CMOS technology. The 74HC08 family was widely used in digital control, timing, clock-gating, counters, instrumentation, industrial electronics, vintage computers, test equipment, and digital-control sections of communications and consumer equipment.

The exact National Semiconductor MM74HC08N DIP version is OBSOLETE / DISCONTINUED. Modern 74HC08-family devices remain available from other manufacturers, but original National Semiconductor DIP devices are increasingly useful for repairing older equipment, maintaining period-correct construction, or replacing an original device with the same vintage manufacturer and package style.

HISTORICAL BACKGROUND:

The MM74HC08 comes from the development era of high-speed CMOS logic, when semiconductor manufacturers were producing CMOS logic capable of approaching TTL switching speeds while dramatically reducing power consumption. National Semiconductor offered the MM74HC08N in the traditional 14-lead plastic dual-in-line package, making it common in through-hole digital equipment of the period.

Current RF Boneyard stock includes original National Semiconductor devices with production/lot markings including P9430AD, P9252, and P9424SD. These markings are preserved for identification and provenance; RF Boneyard does not claim a specific manufacturing date from these factory codes unless independently verified.

The 74HC08 function became widely used across computers, counters, digital clocks, instrumentation, industrial control systems, test equipment, communications hardware, and other equipment requiring straightforward digital AND-gate logic.
