The UT54ACS157 and the UT54ACTS157 are monolithic data
selectors/multiplexers. A 4-bit word is selected from one of two
sources and is routed to the four outputs. A separate strobe
input, G, is provided.
The devices are characterized over full military temperature
range of -55°C to +125°C.

2. Supplied as a design limit but not guaranteed or tested.
3. Per MIL-PRF-38535, for current density
≤

, 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 V

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).
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.
