SN74ABT373DWG4

The SN74ABT373DWG4 is a type of logic latch based on CMOS technology. Its main advantages are low-power consumption and a wide operating voltage range for stability and reliability. It provides a higher level of performance than the traditional D-type latch, making it suitable for use in a variety of applications.

Overview

The SN74ABT373DWG4 is a dual-input latch designed for use in logic applications. It is formed of two identical standard logic devices connected in series. It requires two control inputs, the Clock (CK) and the Enable (EN) and two data inputs, the Data input (DI) and the Complementary Data Input (CDI). The output of the SN74ABT373DWG4 is an active-low open collector latch configuration, which is ideal for driving LED\'s, relays, and other load elements.

Applications

The SN74ABT373DWG4 is suitable for use in a wide range of applications, including memory expansion and control circuits, data and address buses, and multiplexer/demultiplexer circuits. With proper design and layout, it can also be used in designing central processing units (CPUs), microcontrollers, field-programmable gate arrays (FPGAs), and Application Specific Integrated Circuits (ASICs).

Working Principle

The SN74ABT373DWG4 has two active-low inputs, the Clock (CK) and the Enable (EN). When CK is asserted, the DI and CDI inputs are inverted, and the output is latched at the corresponding logic state. When EN is held low, the output of the device is disabled. When CK transitions from Logic 1 to Logic 0, the output is forced to the corresponding logic state and EN is ignored. When CK is held high, the device is in reset mode, and the latch is disabled.

The SN74ABT373DWG4 is a reversible circuit, which means that data can be both forwarded as well as be changed without the need for an additional external IC. Additionally, the capabilities of the latch are enhanced by the active-low configuration of both control signals, which allows for powering the device higher than the supply voltage without any additional external components.

Conclusion

The SN74ABT373DWG4 is an ideal solution for applications requiring low-power, wide operating voltage range, and a higher performance release than traditional D-type latches. It features two active-low inputs, two data inputs, and an active-low open-collector output, making it suitable for use in a variety of applications. Additionally, it is reversible and requires only two external components to operate, allowing for easy and economical PCB designs.The specific data is subject to PDF, and the above content is for reference
