{http://pan.baidu.com/share/link?shareid=44472&uk=4147086434}Shape is about 12mm*12mm, working voltage 2v-5v, timing time can be set from small 2 seconds to 1000 hours, see the description below:
Function and design description:
1. The circuit is connected and set the time resistor and supply voltage as required;
2. The output is high level before power-on without triggering;
3. Trigger terminal "falling edge" trigger is valid, the output becomes low immediately after the trigger and the circuit starts timing;
4. After the set timing time, the output will be restored to high level, waiting for the next "falling edge" trigger;
5. The chip is a non-repeating trigger type, meaning that if the chip output continues to trigger during the low level period after the trigger, the trigger will be invalid;
6. The "falling edge" trigger refers to the moment of change from high level to low level;
7. Generally high level refers to the VCC voltage, low level refers to 0-0.3v or GND, as long as the level requirements can be met;
8. Trigger can be connected to the ground touch switch or microcontroller IO port or other digital circuits to produce a "falling edge" can be triggered effectively;
9. Can be designed as a power-up trigger, only the trigger terminal shorted to ground, power-up is triggered, time to the output is restored to a high level, waiting for the next
The output will be restored to high level after the time expires, waiting for the next falling edge to be triggered again.
Chip features:
1. Low power consumption by CMOS process, lead- and environmentally friendly.
2. Output low level can be pushed directly to the LED (please add current-limiting resistor), output high level can be pushed transistor (please add current-limiting resistor).
3. Resistors can be used to adjust the timing time, there are 8 * N (N = 0.1.2.3) times the timing options, the time can be adjusted from 2s-1000h.
4. Trigger timing and trigger terminal connected to the ground power timing can be selected.
5. Standby output high level, falling edge triggering, low level output after triggering, high level restored after delay.
