The NA556D is a primarily used for timing and oscillator applications, primarily as a programmable timer and oscillator modifier. Designed for use primarily in industrial applications, it is known for its accurate and stable performance. This allows for precise control over the desired application\'s temporal interval behaviors.

The NA556D is a monolithic dual timer comprised of two independent interning circuits, both of which feature two CMOS (Complementary Metal Oxide Semiconductor) timer/oscillators. The first stage of the timer is comprised of a variable resistor and capacitor, with the second stage being a bistable flip-flop.

The variable resistor in the first stage determines the charging time of the capacitor, allowing the user to specify a precise time interval for the timer. The second stage production of the NA556D enables users to reset the time interval without reaching a power cycle, thereby making the timer easier to use.

Overall, the two timer/oscillators offer 16 different waveforms, which can be programed using standard inputs. Each waveform is measured in relation to the other in order to obtain precision and accuracy. This also helps to extend the life of the unit as wear and tear is limited due to constant usage.

A unique feature of the NA556D is a stop/start function that allows the user to momentarily pause the timer/oscillator without having to reset the entire system. This helps to reduce the time it takes to restart the system, and is useful when implementing complex oscillator sequences in time critical applications.

The NA556D application field covers a range of industries and functions. This includes medical instruments, scientific equipment, process timers and several motor control circuits. The timer is also used as part of power saving and consumer electronics designs such as computer monitors, televisions and gaming consoles.

The main advantages of using the NA556D for timing and oscillator applications is its ability to accurately and precisely control the timing interval of given applications. The stop/start feature also offers flexibility in a wide range of applications and the various waveforms offer the user greater control over the desired timing interval.
