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 3,765pF/

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 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) per MIL-STD-883 Method 1019.

8. Power dissipation specified per switching output.

9. Guaranteed by characterization, but not tested.
