Oscillator load: Standard TTL loads (see table I). Output waveform: Symmetrical square wave. Output voltage: Logic 1: 2.4 V dc, minimum at 400 µA source. Logic 0: 0.5 V dc, maximum with 16 mA sink. Rise and fall times: See table I. Duty cycle: See table I. Supply voltage: 5.0 V dc ±10 percent. Input current: At designated supply voltage (see table I). Output frequency: Frequency as designated at time of acquisition (see table I). Initial accuracy at reference temperature (up to 30 days after shipment): See table I. Initial frequency-temperature accuracy (one-half temperature cycle): Verification applicable. 1/ 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/ 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 frequencytemperature accuracy (one-half temperature cycle)’ shall apply except that frequency measurements shall be referenced to the frequency measured at +23°C ±1°C (fref) instead of to the nominal frequency (fnom). 2 MIL-PRF-55310/19D TABLE I.
