The 74ALVTH16373GRE4 is a general-purpose register latch, which is classified as part of the family of logic latches. A latch is a digital circuit that contains an input and output, and an internal memory. In this case, the 74ALVTH16373GRE4 specifically is an 8-bit latch, meaning it has 8 inputs and 8 outputs, and its internal memory can hold 8 bits at any given time.

Featuring high-speed operation and a wide operating voltage range of 2.7V to 5.5V, the 74ALVTH16373GRE4 is designed to be used in a variety of different applications. These include computer systems, auto leveling, fans, motor control, light control systems, and more where applications requiring large amounts of data, quickly and accurately need to be triggered. In all these applications, the 74ALVTH16373GRE4 works by using a small amount of power and transferring the data quickly and with minimal latency.

To understand the working principle of the 74ALVTH16373GRE4 latch, it’s important to understand some of its key components. In addition to the 8 inputs and 8 outputs, the part also has two enable inputs (A1A2) and two active-low enable outputs (B1B2). The enable inputs control the flow of data within the latch, allowing the user to either enable or disable the data transfer. To enable the transfer, A1A2 must both be asserted (high). When the enable input is asserted, data is transferred from the 8 inputs to their respective 8 outputs.

In addition to the enable inputs, the 74ALVTH16373GRE4 contains two clock inputs (CK and nCK). The CK and nCK inputs work in tandem, allowing data to move from the inputs to the outputs, and vice versa. By applying a low-to-high transition on the CK input, the data on the inputs is latched into the memory, so it can be accessed later.

The 74ALVTH16373GRE4 also contains latched enable outputs. These outputs provide a signal to indicate whether or not data is being transferred in real-time. When data is being sent, the active-low enable output will be low. This helps prevent false triggering of the latch, ensuring that data is transferred properly.

Lastly, the 74ALVTH16373GRE4 has two reset inputs (R/S1R/S2). The reset inputs allow the latch to be reset, meaning any data that has been stored can be wiped away. This is useful in situations where the same data needs to be sent multiple times, without any variation.

Overall, the 74ALVTH16373GRE4 is an extremely useful part for applications where data needs to be transferred quickly, precisely, and reliably. Its feature set makes it suitable for a wide range of different applications, with the ability to operate at high speeds and provide accurate data transfer.
