Package

The NA555DR is packaged in a 8-pin SOIC (Small Outline Integrated Circuit) format. This surface-mount package design is suitable for compact electronic applications.

Pinout

The NA555DR is a dual timer integrated circuit with a total of 8 pins. Here’s a concise breakdown of each pin's function:
1. Pin 1 (GND): Ground connection.
2. Pin 2 (TRIG): Trigger input; a negative pulse on this pin starts the timing interval.
3. Pin 3 (OUT): Output; delivers the timing signal.
4. Pin 4 (RESET): Reset input; an active low signal resets the timer.
5. Pin 5 (CTRL): Control voltage; used to modify the timing interval.
6. Pin 6 (THRS): Threshold; voltage at which the timer resets.
7. Pin 7 (DISCH): Discharge; connects to the timing capacitor and discharges it when the timer resets.
8. Pin 8 (VCC): Power supply; connects to the positive voltage (typically between 4.5V and 15V).
The NA555DR can operate in monostable or astable modes, making it versatile for timing and pulse generation applications.
