• Wide power supply operating range from 3.0V to 5.5V
• Available QML Q or V processes
• 14-lead flatpack
• UT54ACS86E - SMD 5962-96538
DESCRIPTION
The UT54ACS86E is a performance and voltage enhanced ver-
sion of the UT54ACS86 quadruple, two-input Exclusive OR
gate. The circuits perform the Boolean functions Y = A
⊕
B or
Y = AB + AB in positive logic.
An application is as a true/complement element. If one of the
inputs is low, the other input will be reproduced in true form at
the output. If one of the inputs is high, the signal on the other
input will be reproduced inverted at the output.
The device is characterized over full military temperature range
of -55°C to +125°C.

IL
= V
IL
(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 V

IL
(max).
2. Supplied as a design limit but not guaranteed or tested.
3. Per MIL-PRF-38535, for current density
≤5.0E5
amps/cm

, 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 V
SS
at
frequency of 1MHz and a signal amplitude of 50mV rms maximum.
6. Maximum allowable relative shift equals 50mV.
7. For devices procured with a total ionizing dose tolerance guarantee, the post-irradiation performance is guaranteed at 25°C per MIL-STD-883 method 1019 condition
A up to the maximum TID level procured.
8. Power dissipation specified per switching output.
9. Guaranteed by characterization, but not tested.
