Hewlett-Packard HP 1820-0141 74H08N Quad 2-Input AND Gate High-Speed TTL IC DIP-14 Vintage NOS – 1 Piece
$14.95
Genuine vintage Hewlett-Packard OEM-marked 74H08N high-speed TTL logic integrated circuit carrying HP service part number 1820-0141. THIS LISTING AND PRICE ARE FOR ONE (1) IC.
The device contains four independent 2-input AND gates in a standard 14-pin through-hole DIP package. The 74H08 belongs to the original high-speed 74H TTL logic family developed for faster digital switching than standard 7400-series TTL. These devices were used in computer logic, digital control circuits, counters, timing systems, laboratory instruments, data-processing equipment, industrial electronics, and other professional digital systems.
IMPORTANT LIFECYCLE INFORMATION: The HP 1820-0141 / original 74H08-class device is OBSOLETE / DISCONTINUED legacy technology. Original-period replacements are now primarily found as NOS, surplus, or salvaged vintage inventory. This makes properly identified old-stock examples particularly useful for restoration of equipment where an original 74H-series device or HP service-numbered component is required.
The photographed IC is marked 74H08N, 7821, and 1820-0141. The 7821 production marking is retained as part of the component identification and provenance. RF Boneyard does not assign an exact manufacturing date to this code without verified manufacturer-specific documentation.
HISTORICAL BACKGROUND:
HP part number 1820-0141 has substantial history in early Hewlett-Packard digital equipment. Period HP service documentation identifies 1820-0141 as a TTL quad 2-input AND-gate service component and cross-references the number to the Motorola MC3001P, an early high-speed TTL quad AND gate.
HP documented 1820-0141 devices in equipment including the HP 2100A computer system and associated digital assemblies. The same HP service number also appears in documentation for HP 9830-series computing equipment and HP disc-drive interface hardware. These applications place the 1820-0141 family firmly in the era when Hewlett-Packard built sophisticated computers, calculators, laboratory instruments, and peripheral systems using discrete TTL logic.
Original HP-numbered logic components are useful today because restorers often encounter an HP service number on schematics or parts lists rather than a modern commercial IC designation. Keeping the 1820-0141 number together with the visible 74H08N marking makes this component easier to identify when servicing period-correct Hewlett-Packard equipment.
