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-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 +70C 0.2C at intervals of not more than every 72 hours for a
minimum of 30 days (see table I).

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.
Nonoperating: Test condition D.
Operating: Not required.
Ambient pressure:
Nonoperating: In accordance with MIL-PRF-55310.
Operating: Method 105 of MIL-STD-202, test condition C.
