Shape about 12mm * 12mm, operating voltage 2v-5v.
timing can be set to a minimum to a maximum of 2 seconds 1.000 hours, as indicated below description.
|
| 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. |

Chip Features:
| The use of low-power CMOS technology, lead-free and environmentally friendly. |
| Direct Push can output low LED (please add current limiting resistor), the output high may push transistor (please add current limiting resistor). |
| Available resistance adjusting timing, there are 8 * N (N = 0.1.2.3) times the timing selection,time can be adjusted from 2s-1000h. |
| Optional trigger timing and triggering termination ground electric timer. |
| Standby output high, falling edge trigger, post-trigger output low, after the delay recovery high. |
