DS1238
NOTES:
1. All voltages referenced to ground.
2. Measured with V CCO , CEO , PF, ST , RST, RST , and NMI pin open.
3. I CCO1 is the maximum average load which the DS1238 can supply at V CC -.3V through the V CCO pin
during normal 5-volt operation.
4. I CCO2 is the maximum average load which the DS1238 can supply through the V CCO pin during data
retention battery supply operation, with a maximum drop of 0.8 volts for commercial, 1.0V for
industrial.
5. With t R = 5 μ s.
6. V CCO is approximately V BAT -0.5V at 1 μ A load.
7. t REC is the minimum time required before CEI / CEO memory access is allowed.
8. t CE maximum must be met to insure data integrity on power loss.
9. All outputs except RST which is 25 μ A max.
10. All outputs except RST , RVT , and NMI which is 25 μ A min.
11. The ST pin will sink +50 μ A in normal operation. The OSCIN pin will sink ± 5 μ A in normal
operation. The OSCSEL pin will sink ± 10 μ A in normal operation.
12. I BAT is measured with V BAT =3.0V.
13. ST should be active low before the watchdog is disabled (i.e., before the ST input is tristated).
