Logic - Latches are digital devices that are used to store information or state. SN74HC373DWR is a type of latch which utilizes the well-known HC CMOS technology to enable numerous application fields and provide an understanding of its working principle. This article will discuss its application field and working principle.

SN74HC373DWR is an octal D-type flip-flop device with latch-enable (LE) inputs. It is a 16-pin package device and has an active-low enable (low-asserted). It is constructed with two Flip-Flop circuits and can be used to store two octal numbers, making it suitable for applications like scan chains, serial-to-parallel data conversion, data buffering and storage register. 

The Flip-Flop circuits found in SN74HC373DWR can be considered as two 4-bit registers. Each Flip-Flop circuit is composed of four D-type latches, making it eight latches in total. Each latch is typically composed of two NAND gates and is used to store a single bit of information. The inputs of each latch are arranged as four data inputs (D1 to D4), one clock input (C) and one latch-enable input (LE). When LE input is high, data can be stored in the latch and will be maintained, even after the clock input returns to the high state.

The SN74HC373DWR is capable of providing an asynchronous reset, which can be used to reset the state of the latch without the need of having an additional latch-enable input. SN74HC373DWR is compatible with many TTL logic gates and hence it can be used in various circuits that use logic gates as building blocks, with minimal redesign. All the pins mentioned above can be individually configurable in terms of logic levels.

SN74HC373DWR has a very low active-low power supply voltage (VCC) of 2.0V and the frequency at which it operates can go up to 40MHz. It has a low maximum input current IOL and a very low capacitance CIN, making it an ideal device to be used in circuits with high speed quinary operation or where a fast response is required. Some of the key features of SN74HC373DWR also include output short-circuit protection, XOR/XNOR inverting and non-inverting logic functions, high output drive current provision, and ESD protection.

SN74HC373DWR can find applications in many different fields such as embedded system design and control, computer, industrial and communication electronic products. It can also be used in high-performance data processing systems in which its fast operation and medium power dissipation can be an advantage. SN74HC373DWR is available in a standard 400-mil SOIC-14 plastic package, making it suitable for use in a variety of applications.

To conclude, SN74HC373DWR is a versatile device belonging to the Logic - Latch family that can provide solutions for various applications by using its logic circuits and asynchronous reset feature. Its application field and working principle have been discussed in detail in this article.
