DESCRIPTION
The UT54ACS138 and the UT54ACTS138 3-line to 8-line de-
coders/demultiplexers are designed to be used in high-perfor-
mance memory-decoding or data-routing applications requiring
very short propagation delay times.
The conditions at the binary select inputs and the three enable
inputs select one of eight output lines. Two active-low and one
active-high enable inputs reduce the need for external gates of
inverters when expanding. A 24-line decoder can be implement-
ed without external inverters and a 32-line decoder requires only
one inverter. An enable input can be used as a data input for
demultiplexing applications.
The devices are characterized over full military temperature
range of -55 C to +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
3,765 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 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.
