Texas Instruments SN74S08N Quad 2-Input AND Gate Schottky TTL IC DIP-14 Vintage – 1 Piece
$4.95
Genuine vintage Texas Instruments SN74S08N Schottky TTL logic integrated circuit in a 14-pin through-hole DIP package. THIS LISTING AND PRICE ARE FOR ONE (1) IC.
The SN74S08N contains four independent 2-input positive-AND gates and belongs to the classic Texas Instruments 74S Schottky TTL logic family. It is designed for 5V digital logic applications and was used in digital control circuits, timing logic, counters, computers, instrumentation, industrial electronics, communications equipment, test equipment, and other systems requiring fast TTL AND-gate operation.
IMPORTANT LIFECYCLE INFORMATION: The exact Texas Instruments SN74S08N is NOT obsolete. The SN74S08 family remains ACTIVE. This RF Boneyard example is vintage old stock, but the underlying SN74S08N part number itself remains active and should not be classified as obsolete or discontinued.
HISTORICAL BACKGROUND:
The 74S series was one of the classic Schottky TTL logic families widely used during the growth of digital electronics in the 1970s and 1980s. Compared with standard TTL, Schottky TTL offered faster switching performance, making parts such as the SN74S08 useful in higher-speed digital logic, counters, control circuits, computer boards, and instrumentation.
The photographed device carries the Texas Instruments marking M7523. RF Boneyard preserves this marking as part of the component’s identification and provenance. No exact manufacturing date is being assigned to the M7523 code because a verified Texas Instruments date-code interpretation has not been established for this specific device.
The SN74S08N should not be confused with the SN74LS08N Low-Power Schottky version. Although both devices provide four 2-input AND gates and use a 14-pin DIP package, their electrical characteristics, switching speed, power consumption, loading, and timing requirements differ. Buyers should verify the required logic family before substitution.
