Equivalent

The NA556N is a dual version of the popular 555 timer IC. Equivalent products include the NE556, SA556, SE556, and LM556. These ICs typically offer similar functionalities and pin configurations, allowing them to be used interchangeably in circuits designed for timing, pulse generation, and oscillation applications. Always check the datasheets for specific electrical characteristics to ensure compatibility.

Features

The NA556N typically refers to a dual precision timer IC, similar to the well-known NE555 timer. It includes two independent, high-stability timers in a single package, which can be used for generating precise time delays or oscillation. Key features often include:
1. Dual Timer: Contains two separate 555 timer circuits in one package, which can be used independently or together for applications needing multiple timekeeping functions.
2. Operating Voltage: Wide range, usually from 4.5V to 15V, accommodating various circuits.
3. Timing Capacitor: Utilizes external resistors and capacitors for timing adjustments, offering flexibility.
4. Astable Mode: Functions as an oscillator for generating continuous square waves.
5. Monostable Mode: Acts as a one-shot pulse generator, producing a single pulse when triggered.
6. Stability: High temperature and supply voltage stability for reliable performance.
7. Output: Capable of sourcing or sinking current, useful for driving loads.
These features make the NA556N suitable for applications like pulse generation, LED flashers, and tone generation.

Pinout

The NA556N is a dual version of the 555 timer IC. It contains two independent 555 timers in a single 14-pin package. Each timer can be configured for monostable or astable operation. Here's the pin configuration and function:
1. GND (Pin 7 for Timer 1, Pin 14 for Timer 2): Ground reference point.
2. Trigger (Pin 6 for Timer 1, Pin 8 for Timer 2): Trigger input to start the timing interval.
3. Output (Pin 5 for Timer 1, Pin 9 for Timer 2): Output pin delivering the timer's output signal.
4. Reset (Pin 4 for Timer 1, Pin 10 for Timer 2): Resets the timer when set to low.
5. Control Voltage (Pin 3 for Timer 1, Pin 11 for Timer 2): Alters the threshold voltage; often left unconnected.
6. Threshold (Pin 2 for Timer 1, Pin 12 for Timer 2): Comparator input to end the timing interval.
7. Discharge (Pin 1 for Timer 1, Pin 13 for Timer 2): Discharge pin for timing capacitor.
8. VCC (Pin 14): Positive supply voltage ranging typically from 4.5V to 15V.
This IC is used in various applications like pulse generation, timers, and oscillators.
