Specifications:
Shape about 12mm * 12mm operating voltage 2v-5v
timing can be set to a minimum to a maximum of 2 seconds 1000 hours as indicated below description
Function and Design
1. The circuit according to claim connected and set a good time resistance and supply voltage;
2. Before the power not trigger output is high;
3. Trigger terminal falling trigger effective immediately
after the trigger output terminal goes low at the same time start the timer circuit;
4. Set the timer time to recover after the output terminal is high wait for the next falling trigger;
5. 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;
6. The trigger end of falling Trigger refers to the instantaneous change from high level to a low level;
7. General refers to VCC high voltage low means 0-0.3v or GND
provided that they meet the level requirements can be;
8. trigger terminal can be connected to touch switch or microcontroller IO port or
other digital circuits have a falling can effectively trigger;
9. 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.
Chip Features:
1. The use of low-power CMOS technology lead-free and environmentally friendly.
2. Direct Push can output low LED
(please add current limiting resistor) the output high may push transistor (please add current limiting resistor).
3. Available resistance adjusting timing there are 8 * N (N = 0.1.2.3) times the timing selection
time can be adjusted from 2s-1000h.
4. Optional trigger timing and triggering termination ground electric timer.
5. standby output high falling edge trigger post-trigger output low after the delay recovery high.
Package Included:
* Multifunction Delay Trigger Timing Chip Mudule Timer IC Timing 2s - 1000h
