The NE556DT Programmable Timers and Oscillators is a versatile and reliable, integrated circuit timer. It is designed for applications requiring a maximum of 1 MHz frequency in more complex circuits. It has a wide range of applications including clock, timing, counting and oscillating.

A basic NE556DT circuit consists of 16 pins. Pins 1, 2 and 3 are the power supply pins, while pins 5 and 6 are the output pins. The remaining pins are used to control the timing functions within the unit. The NE556DT contains two conventional 555 timer circuits, each having their own internal resistor and capacitor networks, which allows one timer to be used as the timing source and the other as the reset signal source.

The NE556DT has many programmable features, including an adjustable pre-set count, adjustable rise and fall times, and adjustable threshold voltage. It also features an active low over-current limiter, which restricts the output current at certain levels. This over-current limiter protects the NE556DT from electrical surges from external sources.

The NE556DT is highly reliable and accurate. It is designed to withstand high temperatures, up to 150°C, and has excellent noise immunity. It is also characterized for low power consumption, making it suitable for battery-operated devices.

In an application, the NE556DT can be used as a programmable timer, frequency generator, oscillator, or counter. As a programmable timer, the NE556DT can generate a signal, either with or without an external trigger signal. It is typically used as an on/off timer, to switch something on at a given time, or switch it off after a certain pre-set time.

As a frequency generator, the NE556DT can generate a signal with a frequency range of 25 kHz to 1 MHz. It can also be used as an oscillator, to provide a stable signal source for signal processing or signal processing applications.

As a counter, the NE556DT can be used to count the number of times an event has occurred, or the number of pulses on an input signal. The programmable output can be used to generate a specific signal type or a signal with a specific frequency. It can also be used as a timer for timing activities such as events or for operation for predetermined periods of time.

The NE556DT Programmable Timers and Oscillators is an ideal solution for high frequency and accuracy generation applications, such as clock and timing or counter applications, or as an oscillator in signal processing or signal conditioning applications.
