Genuine vintage Texas Instruments SN74LS08N Low-Power Schottky TTL logic integrated circuit in a 14-pin through-hole DIP package. THIS LISTING AND PRICE ARE FOR ONE (1) IC.

The SN74LS08N contains four independent 2-input positive-AND gates. It is part of Texas Instruments’ classic 74LS bipolar logic family and operates from a 4.75V to 5.25V supply. The device was designed for digital logic, gating, timing, control, counters, computers, instrumentation, industrial electronics, test equipment, communications equipment, and other systems requiring reliable TTL AND-gate functions. Texas Instruments specifies the SN74LS08 family as a four-channel, two-input bipolar AND gate and continues to offer the 14-pin PDIP package. ([Texas Instruments][1])

IMPORTANT LIFECYCLE INFORMATION: The SN74LS08N is NOT obsolete. Texas Instruments currently classifies the SN74LS08 product family as ACTIVE, and DigiKey lists the exact SN74LS08N 14-PDIP device as Active. This particular RF Boneyard example is genuine vintage production stock, but the underlying part number remains an actively supported logic device. ([Texas Instruments][1])

HISTORICAL BACKGROUND:

The 74LS series was one of the major Low-Power Schottky TTL logic families used during the expansion of digital electronics in the 1970s and 1980s. Period electronics advertising already listed the 74LS08 for sale in 1975, demonstrating how early this logic family had entered widespread commercial distribution. Texas Instruments’ later TTL data books continued to document the SN74LS08 alongside the standard 7408 and faster SN74S08 versions. ([World Radio History][2])

The photographed Texas Instruments device carries the marking G7641. This marking is consistent with a mid-1970s production/date-code format and is likely associated with 1976 production, potentially week 41, although RF Boneyard does not guarantee the exact internal Texas Instruments factory-code interpretation. Its period markings and older TI package style make this particular device useful not only as functional repair stock but also for restorers seeking an era-appropriate semiconductor for vintage digital equipment.

Unlike the faster SN74S08 Schottky device also found in this intake group, the SN74LS08N belongs specifically to the LS Low-Power Schottky family. Although both perform the same basic quad 2-input AND-gate logic function, their electrical and timing characteristics differ and they should not automatically be treated as identical replacements without checking the original circuit requirements.
