DM54LS279 - Quad S-R Latches

Download the DM54LS279 datasheet PDF. This datasheet also covers the DM54LS279J variant, as both devices belong to the same quad s-r latches family and are provided as variant models within a single manufacturer datasheet.

General Description

The ’LS279 consists of four individual and independent SetReset Latches with active low inputs Two of the four latches have an additonal S input ANDed with the primary S input A low on any S input while the R input is high will be stored in the latch and appear on the corresponding Q output as a hig
