DS1553
070198 15/19
AC TEST CONDITIONS
Output Load:
Input Pulse Levels:
Timing Measurement Reference Levels:
Input: 1.5V
Output: 1.5V
Input Pulse Rise and Fall Times:
100 pF + 1TTL Gate
0.0 to 3.0 Volts
5 ns
NOTES:
1. Voltage referenced to ground.
2. Typical values are at 25
°
C and nominal supplies.
3. Outputs are open.
4. Battery switch over occurs at the lower of either the battery voltage or V
PF
.
5. The IRQ/FT and RST outputs are open drain.
6. Data retention time is at 25
°
C.
7. Each DS1553 has a built–in switch that disconnects the lithium source until V
CC
is first applied by the user. The
expected t
DR
is defined for DIP modules as a cumulative time in the absence of V
CC
starting from the time power
is first applied by the user.
8. Real–Time Clock Modules (DIP) can be successfully processed through conventional wave–soldering tech-
niques 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.
In addition, for the PowerCap:
a. Dallas Semiconductor recommends that PowerCap Module bases experience one pass through solder reflow
oriented with the label side up (“live – bug”).
b. Hand Soldering and touch–up: Do not touch or apply the soldering iron to leads for more than 3 (three) seconds.
To solder, apply flux to the pad, heat the lead frame pad and apply solder. To remove the part, apply flux, heat
the lead frame pad until the solder reflow and use a solder wick to remove solder.
