The devices consist of two individual two-line to four-line decoders in a single package. The active-low enable input can be used as a data line in demultiplexing applications. The devices are characterized over full military temperature range of -55C to +125C.

Stresses outside the listed absolute maximum ratings may cause permanent damage to the device. This is a stress rating only, functional operation of the device at these or any other conditions beyond limits indicated in the operational sections is not recommended. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

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. 5 AC ELECTRICAL CHARACTERISTICS 2 (VDD = 5.0V 10%; VSS = 0V 1, -55C < TC < +125C); Unless otherwise noted, Tc is per the temperature range ordered.
