Overview

DM74LS279 Quad S-R Latch August 1986 Revised March 2000 DM74LS279 Quad S-R Latch General Description The DM74LS279 consists of four individual and independent Set-Reset Latches with active low inputs.
Two of the four latches have an additional 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 transition of the R and S inputs from LOW-toHIGH 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.
