DS1642
11 of 13
AC TEST CONDITIONS
Output Load: 100pF + 1TTL Gate
Input Pulse Levels: 0.0 to 3.0V
Timing Measurement Reference Levels:
Input: 1.5V
Output: 1.5V
Input Pulse Rise and Fall Times: 5ns
NOTES:
1) Voltages are referenced to ground.
2) Typical values are at 25
C and nominal supplies.
3) Outputs are open.
4) Data retention time is at 25
C.
5) Each DS1642 has a built-in switch that disconnects the lithium source until VCC is first applied by the
user. The expected tDR is defined as a cumulative time in the absence of VCC starting from the time
power is first applied by the user.
6) 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.
