Product Information
- Shape about 12mm * 12mm, operating voltage 2v-5v,timing can be set to a minimum to a maximum of 2 seconds 1,000 hours.
- The circuit is connected as required and the time resistance and power supply voltage are set;Before the power not trigger output is high;Trigger terminal "falling" trigger effective immediately after the trigger output terminal goes low at the same time start the timer circuit.
- Set the timer time to recover after the output terminal is high, wait for the next "falling" trigger;The chip is not repeated triggered, meaning that continue to trigger in the period after the trigger chip output low if the trigger is invalid.
- The trigger end of "falling" Trigger refers to the instantaneous change from high level to a low level; General refers to VCC high voltage, low means 0-0.3v or GND,provided that they meet the level requirements can be.
- Trigger terminal can be connected to touch switch or microcontroller IO port or other digital circuits have a "falling" can effectively trigger;The trigger can be designed to power, only to trigger a short circuit to ground, power is triggered,the time to recover after the output to a high level, waiting for the next Falling edge trigger again.
