The SN74HC373PWRE4 is a part of the Logic-Latches family and is a high speed and low power, octal transparent D-type latch which can be used for D to Q data transfer. This part has 8 outputs and operates from 2V to 6V of power supply. It is composed of eight D-type latches with "gated" clock inputs (CP) and an asynchronous master reset (MR) for all eight latches, as shown in the diagram below.

The SN74HC373PWRE4 has two operating modes, the latching mode and the transparent mode. In the latching mode, the output Q of the latch is enabled when the Clock input CP is LOW and disabled when CP is HIGH. The transparent mode is defined by the Data Enable input DE, which enables the output of the latch when LOW. At the same time, it is disabled when DE is HIGH, allowing the data on the inputs to flow to the outputs without being latched. The clock input is disabled in the transparent mode, allowing the data to be transferred without the need for clocking.

The SN74HC373PWRE4 is commonly used for D to Q data transfer applications such as synchronous counters with parallel or multiplexed outputs, data capture, memory update, and other applications requiring octal latches. It provides a mechanism to store up to 8 binary values and allows for versatility in interface, as the latches can easily be reset or data flowed from the input to the output.

This part also has typical uses for multiplexers and demultiplexers, as well as for replacing flip flops, registers or shift registers. It can be used in various digital and analog systems, which require that digital data persist in memory, and then is either changed using a clock or direct input, or needs to be transferred from one point to another. With the SN74HC373PWRE4, the data is transferred and stored without the need of an external clock if a direct enable line is used. This can significantly reduce system complexity, allowing for more efficient and cost effective designs.

In conclusion, the SN74HC373PWRE4 part is a powerful and versatile device that has many applications within the Logic-Latches family. It provides a simple, cost effective way to store and transfer digital data from one point to another and its maximum operating voltage of 6V make it an ideal choice for many applications. The part\'s simple two-mode operation, the transparent and the latching mode, provides versatility in terms of interface and operation, making it a great choice for many different projects.
