Présentation
Description
The IC operates over a wide voltage range, typically from 4.5V to 15V, and can source or sink up to 200mA of current, making it suitable for driving LEDs, relays, or other small loads. It features low power consumption and high stability against temperature variations and supply voltage changes.
The NE556DB comes in a small-outline SOIC-14 package, making it suitable for compact or space-constrained designs. Its robust performance and versatility make it ideal for use in consumer electronics, automotive, and industrial applications. Additionally, the NE556DB is often favored for educational projects and prototyping due to its ease of use and readily available support resources.

Pinout
1. Pin 1 (GND): Ground reference voltage, low-level (0V).
2. Pin 2 (TRIG A): Trigger input for Timer A; a falling edge triggers the timer.
3. Pin 3 (OUT A): Output for Timer A; delivers the timer's pulse.
4. Pin 4 (RESET A): Resets Timer A when a low voltage is applied.
5. Pin 5 (CTRL A): Control voltage for Timer A; adjusts threshold and trigger levels.
6. Pin 6 (THRES A): Threshold input for Timer A; ends the timing interval.
7. Pin 7 (DISCH A): Discharge output for Timer A; discharges the timing capacitor.
8. Pin 8 (VCC): Supply voltage for the integrated circuit.
9. Pin 9 (DISCH B): Discharge output for Timer B.
10. Pin 10 (THRES B): Threshold input for Timer B.
11. Pin 11 (CTRL B): Control voltage for Timer B.
12. Pin 12 (RESET B): Resets Timer B.
13. Pin 13 (OUT B): Output for Timer B.
14. Pin 14 (TRIG B): Trigger input for Timer B.
The NE556DB combines two 555 timers, allowing for dual timing functions within one chip.
