54LS279/DM54LS279/DM74LS279 Quad S-R Latches
■The 'LS279 consists of four individual and independent Set-Reset 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 high. A low on the R input while the S input is high will clear the Q output to a low. Simultaneous transistion of the R and S inputs from low to high will cause the Q output to be indeterminate. Both inputs are voltage level triggered and are not affected by transition time of the input data.
●Features
■Alternate military aerospace device (54L S279) is available. Contact a National Semiconductor Sales Office/Distributor for specifications.
