The UT54ACS109 and the UT54ACTS109 are dual J-K posi-
tive triggered flip-flops. 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 military temperature
range of -55 C to +125 C.

Note:
1. The output levels in this configuration are not guaranteed to meet the mini-
mum levels for V
OH
if the lows at preset and clear are near V
IL
maximum. In
addition, this configuration is nonstable; that is, it will not persist when either
preset or clear returns to its inactive (high) level.
Note:
1. Logic symbol in accordance with ANSI/IEEE standard 91-1984 and
