About this part

The Xinluda XD74LS279 is a quad set-reset (S-R) latch belonging to the industry-standard 74LS279 family of low-power Schottky TTL logic. It packs four independent S-R latches into a single 16-pin device, providing a simple and reliable building block for de-bouncing switches, level latching, and basic memory/storage functions in digital systems. Two of the four latches feature dual active-low Set inputs, giving designers added flexibility for combining control signals, while the remaining two latches use a single Set input.

As a member of the well-established 74LS (Low-power Schottky) TTL series, the XD74LS279 offers the familiar speed/power balance, robust noise margins, and broad design compatibility that have made the 74LS279 a long-running standard across consumer, industrial, and educational electronics.
