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. All specifications valid for radiation dose
≤
1E6 rads(Si) per MIL-STD-883 Method 1019 Condition B.
8. Power dissipation specified per switching output.
9. This value is guaranteed based on characterization data, but not tested.
