NOTES:
1. All voltages are referenced to ground.
DS1818
2. Measured with VCC ≥ 2.7V.
3. A 1 kΩ external pull-up resistor may be required in some applications for proper operation of the
microprocessor reset control circuit.
4. Measured with RST output open.
5. Measured with 2.7V ≤ VCC ≤ 3.3V.
6. tR = 5 µs.
7. VOH and IOH are a function of the value of RP and the associated output load conditions.
8. The tF value is for reference in defining values for tRPD and should not be considered a requirement for
proper operation or use of the device.
