The DS1004Z-3+ is a monolithic programmable delay line which is widely used in Clock/Timing - Delay Lines applications. It is a delay line integrated circuit with a minimum delay of 1 ms. It consists of flip-flops whose clock outputs (Q) are connected together in chain fashion. This delay line can take a wide range of clock signals in, such as, simple clock signals, square waves and other waveforms, determine an average cycle time, then generate a delayed output whose delay time is proportional to the clock cycle time. This advantage makes it highly practical for use in a variety of applications, including timers, automatic test equipment and timing logic. The DS1004Z-3+ can also be used as a variable time-base oscillator in many timing-dependent circuits.

The DS1004Z-3+ utilizes two-level latch architecture. An external clock signal is applied to the CLOCK IN pin from where it is directed to the input of an asynchronous D flip-flop. At the D input of the D flip-flop, the level of the clock signal is activated for a certain delay time of 1 ms. During this time, the D input turns on and activates the D flip-flop, which in turn sends the clock signal to the output of the chip. The output of that chip is then directed to the next D flip-flop, again with a certain delay of 1 ms. This process of continuously activating the D flip-flop and sending the clock output to the next stage of the chain is repeated until the required delay is obtained. The resulting output is taken from the last stage of the chain.

The DS1004Z-3+ is a monolithic programmable delay line which consists of a series of clocked latches that creates an adjustable delay of 1 ms or greater. Each latch receives an input signal which is followed by a certain delay. The design of the circuit also makes it suitable for use in multiple applications as it is highly reliable and consumes less power.

The DS1004Z-3+ is often used for automating test equipment, such as dumbing down, ramping up and re-triggering, or even for the design of timing-detecting circuits. It is also capable of delaying external signals by specific intervals through its set of delay lines and provides accurate real-time synchronization. With a minimum delay of 1 ms, this device can be adjusted to most timing related requirements. Furthermore, it is possible to increase the delay by cascading several units – by adding additional delay lines in parallel.

The main advantages of the DS1004Z-3+ are its simplicity and wide range of possible applications. It requires minimal external components and generates accurate delays in both steady-state and dynamic conditions. This device can be used in a variety of timing related applications such as pulse-width testing, time-base counter, pulse-shaping and synchronization. Furthermore, the device exhibits good performance in high temperature as well as low noise environments – this makes it more reliable than many other timing related components. Additionally, its low power dissipation allows it to be used in small applications and its wide input range facilitates the design of timing sensitive circuits.

The DS1004Z-3+ provides an adjustable delay of 1 ms or more, allowing it to be used for a variety of timing related applications. Its two level latch architecture allows for an extremely low power consumption and the ability to adjust the delay time accurately and quickly. Furthermore, it is suitable for use in both low and high noise environments, as well as extreme temperatures. With its minimal external components, the DS1004Z-3+ is an ideal programmable delay line for any electronic project.
