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 2pF capacitance.
Frequency-voltage tolerance: ±4 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).
±10 ppm per year, maximum
±1.5 ppm per 30 days.
±3 ppm per 90 days.
Frequency-environmental tolerance: Not applicable.
Nonoperating: Test condition G.
Operating: Not required.
Ambient pressure:
Nonoperating: In accordance with MIL-PRF-55310.
Operating: Method 105 of MIL-STD-202, test condition C.
Reflow soldering: Reflow soldering of the unit at +230°C ±10°C for 15 seconds shall not degrade the performance.
