About This Item:

  • Low Power CMOS Process: Utilizes CMOS technology for low power consumption and is lead-free, environmentally friendly.
  • Output Drive Capability: Low-level output can directly drive LEDs (add a current-limiting resistor). High-level output can drive transistors (add a current-limiting resistor).
  • Adjustable Timing: Timing duration is set via a resistor, with 8*N (N=0,1,2,3) timing multiplier options. Timing range adjustable from 2 seconds up to 1000 hours.
  • Trigger Modes: Supports both trigger timer mode and power-on timer mode by connecting the trigger pin to ground.
  • Output Logic: Standby output is high level. Triggered by a falling edge. Upon trigger, output switches to low level and returns to high level after the delay time ends.

Dimensions: 12mm*12mm

Operating Voltage: 2V - 5V

Function and Design Description:

  1. Connect the circuit correctly and set the timing resistor and supply voltage.
  2. Before triggering (power-on state):Output Pin: High level
  3. Trigger Pin: Triggered by a "falling edge". After triggering:Output Pin: Immediately switches to low level.The timing cycle begins.
  4. When the set timing duration ends:Output Pin: Returns to high level, waiting for the next "falling edge" trigger.
  5. Non-Retriggerable: The chip is non-retriggerable. This means any trigger signals received while the output is low (during the timing cycle) are ignored.
  6. Falling Edge Definition: A "falling edge" trigger is defined as the instantaneous change of the trigger pin voltage from high level to low level.
  7. Logic Levels: Generally, high level refers to VCC voltage, and low level refers to 0-0.3V or GND. Triggering is valid as long as these level requirements are met.
  8. Trigger Sources: The trigger pin can be activated by connecting a tactile switch to ground, a microcontroller I/O pin, or other digital circuits capable of generating a "falling edge".
  9. Power-On Trigger Option: Can be configured for power-on triggering by shorting the trigger pin to ground. Upon power-up, the chip triggers immediately, and the output returns to high level after the set time. It can then be triggered again by a falling edge.

Pin Description (from bottom to top in the diagram):

  • PIN1: Power Supply Negative (GND)
  • PIN2: Trigger
  • PIN3: Output
  • PIN4: Power Supply Positive (VCC)

Timing Multiplier Settings:

  • Shorting P1 (short the two small pads): Timing duration = (Resistor table time) x 8
  • Shorting P2 (short the two small pads): Timing duration = (Resistor table time) x 64
  • Shorting both P1 and P2: Timing duration = (Resistor table time) x 512
