DESCRIPTION

The UT54ACS279 and the UT54ACTS279 contain four basic S-R flip-flop latches. 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. If the S-R inputs are taken low simultaneously, the Q output is unpredictable.

The devices are characterized over full military temperature range of -55°C to +125°C.
