Description:
The shape is about 12mm*12mm, the working voltage is 2v-5v, and the timing can be set from a minimum of 2 seconds to a maximum of 1000 hours

Features:
1. The circuit is connected as required and the time resistance and power supply voltage are set. 
2. The output terminal is high before the power is not triggered . 
3. The trigger "falling edge" trigger is valid, and the output is triggered. The terminal immediately goes low and the circuit starts to count; 
4. After the set timing time reaches the output , the output returns to the high level, waiting for the next "falling edge" trigger; 
5. The chip is not repeated trigger type, meaning The trigger is invalid when the chip continues to trigger during the low output period after the trigger. 
6. The "falling edge" trigger of the trigger terminal refers to the moment of change from high level to low level; 
7. The general high level refers to the VCC voltage. Low level means 0-0.3v or GND, as long as it meets the level requirement; 
8. The trigger end can effectively trigger the grounding touch switch or the IO port of the MCU or other digital circuits to generate a "falling edge"; 
9. It can be designed as a power-on trigger. It only needs to short-circuit the trigger terminal to the ground. It will be triggered when the power is turned on. After the time is up, the output will return to the high level and wait for the next 
falling edge to trigger again.

Specifications:
1. Low power consumption in CMOS process, lead-free environmental protection. 
2. Output low level can directly push the LED (please add current limiting resistor), output high level can push the triode (please add current limiting resistor). 
3. Available resistor timing, 8*N (N=0.1.2.3) times timing selection, time can be adjusted from 2s-1000h. 
4. Select the trigger timing and trigger grounding power-on timing. 
5. Standby output high level, falling edge trigger, output low level after trigger, return high level after delay.
