• 16-lead flatpack
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 military 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.

DC ELECTRICAL CHARACTERISTICS FOR THE UT54ACS109E7
( VDD = 3.0V to 5.5V; VSS = 0V6; -55°C < TC < +125°C)
Notes:
1. Functional tests are conducted in accordance with MIL-STD-883 with the following input test conditions: VIH = VIH(min) + 20%, - 0%; VIL = VIL(max) + 0%, -
50%, as specified herein, for TTL, CMOS, or Schmitt compatible inputs. Devices may be tested using any input voltage within the above specified range, but are
guaranteed to VIH(min) and VIL(max).
2. Supplied as a design limit but not guaranteed or tested.
3. Per MIL-PRF-38535, for current density ≤5.0E5 amps/cm2, the maximum product of load capacitance (per output buffer) times frequency should not exceed 3,765pF/
MHz.
4. Not more than one output may be shorted at a time for maximum duration of one second.
5. Capacitance measured for initial qualification and when design changes may affect the value. Capacitance is measured between the designated terminal and VSS at
frequency of 1MHz and a signal amplitude of 50mV rms maximum.
6. Maximum allowable relative shift equals 50mV.
7. All specifications valid for radiation dose ≤ 1E6 rads(Si) per MIL-STD-883 Method 1019 Condition B.
8. Power dissipation specified per switching output.
9. This value is guaranteed based on characterization data, but not tested.
