Overview
The SN74LS279ANS, produced by Texas Instruments, is a quadruple S-R latch integrated circuit. This component offers four basic S-R flip-flop latches packaged in a 16-pin, 300-mil package. Under conventional operation, the S-R inputs are normally held high. When the S input is pulsed low, the Q output will be set high, and when the R input is pulsed low, the Q output will be reset low. It is important to note that the S-R inputs should not be taken low simultaneously, as this condition can result in unpredictable Q output behavior.
