DESCRIPTION
The UT54ACS109E is a dual J-K positive triggered flip-flop.
A low level at the preset or clear inputs sets or resets the outputs
regardless of the other input levels. When preset and clear are
inactive (high), data at the J and K input meeting the setup time
requirements are transferred to the outputs on the positive-going
edge of the clock pulse. Following the hold time interval, data
at the J and K input can be changed without affecting the levels
at the outputs. The flip-flops can perform as toggle flip-flops
by grounding K and tying J high. They also can perform as D
flip-flops if J and K are tied together.
The devices are characterized over full HiRel temperature range
of -55
°C to +125°C.
FUNCTION TABLE
Note:
1. The output levels in this configuration are not guaranteed to meet the mini-
mum levels for VOH if the lows at preset and clear are near VIL maximum.
In addition, this configuration is nonstable; that is, it will not persist when
either preset or clear returns to its inactive (high) level.
