AC TEST CONDITIONS

Output Load:

100 pF + 1TTL Gate

Input Pulse Levels:

0.0 to 3.0 Volts

Timing Measurement Reference Levels:

Input: 1.5V

Output: 1.5V

Input Pulse Rise and Fall Times: 5 ns

NOTES:

1. Voltage referenced to ground.

2. Typical values are at 25

°C and nominal supplies.

3. Outputs are open.

5. Data retention time is at 25

°C.

power is first applied by the user.

7. Real Time Clock Modules can be successfully processed through conventional wave-soldering

techniques as long as temperature exposure to the lithium energy source contained within does not

exceed +85

°C.

Post-solder cleaning with water washing techniques is acceptable, provided that

ultrasonic vibration is not used to prevent damage to the crystal.
