TABLE I. Dash numbers and operating characteristics.
1/ Maximum input current for no load condition. Actual configuration of TTL loads must be added to determine
power supply requirements.
2/ A TTL unit load is defined as: 1.6 mA sink, 0.04 mA source, and 2 pF capacitance.
Frequency-temperature tolerance (one-half temperature cycle, referenced to frequency measured at +23
C 1C,
immediately prior to starting of the test): See table I. Measurements taken at ten equally spaced increments
over the specified operating temperature range. 1/
Frequency-voltage tolerance:
2 ppm maximum for a 10 percent change in supply voltage. Measurements taken
at reference temperature and operating temperature range end points.
Frequency aging: Measurements shall be taken at +70
C 0.2C at intervals of not more than every 72 hours for
30 days minimum (see table I).
5 ppm per year, maximum 10 ppm per year, maximum
0.7 ppm per 30 days. 1.5 ppm per 30 days
1.5 ppm per 90 days 3 ppm per 90 days
Terminal strength:
Method 211 of MIL-STD-202 , test condition C.
Applied force: 2 pounds each terminal for 10 seconds.
Bends: Five at 45 degrees each.
Frequency-environmental tolerance: Not applicable.
1/ For the purpose of transitioning this device to MIL-PRF-55310 , ‘Frequency stability versus temperature’ has
been renamed ‘Frequency-temperature tolerance’. The verification requirements of ‘initial frequency-
temperature accuracy (one-half temperature cycle)’ shall apply except that frequency measurements shall
be referenced to the frequency measured at +23
C 1C (f
ref
) instead of to the nominal frequency (f
nom
).
