NOTES:
1. All voltages are referenced to ground.
2. Measured with V
CCO
, CEO and WEO open.
3. I
CCO
is the maximum average load that the DS1234 can supply to the memories.
4. Measured with a load as shown in Figure 2.
5. I
CC01
is the maximum average load current that the DS1234 can supply to the memories in the battery back-
up mode.
6. CEO and WEO, outputs can only sustain leakage current in the battery backup mode.
7. I
BAT
is the total load current that the DS1234 uses from the battery input pin with V
