More Information

The ’279 offers 4 basic S-R flip-flop latches in one 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. When R is pulsed low, the Q output will be reset low. Normally, the S-R inputs should not be taken low simultaneously. The Q output will be unpredictable in this condition.
