Pin-selectable Interval Timer IC S-35730 Series

The interval timer IC allows for intermittent system operation by inputting a signal to the system at fixed periods of time.
The S-35730 outputs the interval signal (clock pulse).
One interval signal (clock pulse frequency) can be selected from "32.768 kHz", "32 Hz", "1.024 kHz", and "1 Hz" according to the SET0 pin and the SET1 pin settings.

Parts List

  • U(Ux), S and G at the end of the product name of ABLIC Inc. were used to indicate different material specifications as “environmental code”,
    however, these have now been unified into “lead-free and halogen-free” and are identical in terms of environmental quality.
  • Note: Lead-free plating other than 100% Sn is applied to some limited old products, therefore, please contact our sales representatives for details.
  • These descriptions may be different from the actual product name and parameter.
    Please confirm the product name and specifications with the data sheet again.
