PUSHBUTTON TIMING DIAGRAMS Figure 4

DS1809

If during any pushbutton activity the STR input is activated, pushbutton operation will be suspended until

the storage of EEPROM has been completed. Once complete, pushbutton inputs, if still active, will

resume from the point of suspension. Command initiated storage operations will require a minimum of

4 ms to complete the storage operation. This 4ms is measured from the rise of STR input (see Figure 5).

For applications not requiring or using the nonvolatile memory feature of the DS1809, it is recommended

that the STR input be connected to GND.
