15 of 17
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) Voltage referenced to ground.
2) Typical values are at +25°C and nominal supplies.
3) Outputs are open.
4) Battery switchover occurs at the lower of either the battery voltage or VPF.
5) Data retention time is at +25°C.
6) Each DS1742 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.
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.
