MULTIFUNCTION DELAY TRIGGER TIMING CHIP

• The circuit according to claim connected and set a good time resistance and supply voltage;
• 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.

Package Includes:

• • 1 X Multifunction Delay trigger timing chip
