Q2
The UT54ACS74 and the UT54ACTS74 contain two indepen-
dent D-type positive triggered flip-flops. A low level at the
Preset or Clear inputs sets or resets the outputs regardless of the
levels of the other inputs. When Preset and Clear are inactive
(high), data at the D input meeting the setup time requirement
is transferred to the outputs on the positive-going edge of the
CLR1
clock pulse. Following the hold time interval, data at the D
D1
input may be changed without affecting the levels at the oDuatptauStsh. eet4U.coCmLK1
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 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.

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
3,765 pF/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 a 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).
8. Power does not include power contribution of any TTL output sink current.
9. Power dissipation specified per switching output.
10. This value is guaranteed based on characterization data, but not tested.
