Logic latches are used as a means of storing digital information. The type 74ABT841PW,112 is a dual 4-bit latch that stores digital information just like a regular latch but has two separate 4-bit registers. This type of device is used in computer memory and input/output devices, such as keyboards, printers, and displays.

A dual 4-bit latch like 74ABT841PW,112 is commonly used to store two 4-bit data words in parallel. This type of device functions similarly to two individual four-bit latches connected together, with the same control signals being sent to both. This allows for fast data storage, with one clock for both registers.

The 74ABT841PW,112 comprises of two 4-bit latches that use differential data inputs rather than the single-ended input of a standard latches. These latches have both active-high- and active-low-level enable control inputs. By using differential data inputs, the 74ABT841PW,112 can achieve higher speeds and better signal-to-noise ratios.

The 74ABT841PW,112 also includes built-in Schmitt triggers on all of its inputs. Schmitt triggers are functions that align and sharpen digital signals that may be distorted by previous stages of logic, ensuring reliable data transfer and storage. These triggers improve the noise immunity of the device and allow it to operate at higher frequencies.

The device features a maximum operating frequency of 20MHz, an access time of 4ns and a propagation delay of 4ns. It also includes an output enable control signal, which allows the user to disable the outputs if they are not needed. This feature reduces power consumption, which is particularly useful in battery-powered applications.

The 74ABT841PW,112 is suitable for use in a wide range of applications, such as data storage in computers as well as signal buffering for keyboard and displays. It also has a wide temperature range, making it ideal for operation from -40 to +85 °C in industrial and consumer applications. It comes in the exceptionally small 8-pin plastic TSOP package, ideal for space-constrained designs.

In summary, the 74ABT841PW,112 dual 4-bit latch is an ideal choice for applications that require two four-bit words of data to be stored in a parallel manner. The latch is suitable for a wide range of consumer and industrial applications due to its wide temperature range, fast access time and propagation delay, and its ability to handle digital signals with built-in Schmitt triggers. It also features an output enable control signal to reduce power consumption, making it even more attractive for battery-driven applications.
