Logic - Latches

Latches are a type of logic device that use a memory element to retain a digital state even when power events occur. This feature of latching provides an unlimited supply of logic memory, resulting in a fast and reliable solution to basic logic problems. The SN74AC573PW is one such logic device made by Texas Instruments and is designed to be used in a variety of multiple control and data acquisition systems.

SN74AC573PW Overview

The SN74AC573PW is an 8-bit parallel output register capable of operating from 2.3V to 5.5V on a single supply. It consists of a D-latch comprised of 8 stages, each with 3-state output enabling. They have an open drain output configuration and include redundant CLK, preset, clear and output enable lines. The operation of the latch is extended across multiple power domains. It is available in 16-pin packages.

SN74AC573PW Application Field

The SN74AC573PW is ideal for application in a wide range of systems that require data storage, multiple control logic and fast data transfer. In communication systems, the latch can be utilized in the data path to store and retrieve data at a high speed, while at the same time providing TTL level output. In video display systems, the latch can be used as a memory buffer to facilitate rapid transfers of video data. In data acquisition systems, the latch can be used to store and rapidly recall data, providing a much higher performance than conventional memory. Additionally, the latch can be used in low power control and logic circuits, eliminating the need to use additional power sources.

SN74AC573PW Working Principle

The latch has a single input line, CLK, and an inverted CLK line. It holds a value of ‘1’ when CLK is high, and ‘0’ when CLK is low, regardless of the state of the clear line (CLR). When the output enable line (OE) is high, the outputs are in the high impedance state, but when OE is low, the outputs will reflect the state of the latched data. The latch also has a preset input line (PRE). When this line is high, all outputs will be set to ‘1’ regardless of the latch’s current state. The latch also has an asynchronous clear option which clears the latch when the CLK line is low and the clear line (CLR) is high. When the CLK line is high the latch retains its current state. The latch is available with a 5V tolerant, open drain configuration for automotive applications.

Conclusion

The SN74AC573PW from Texas Instruments is a versatile 8-bit parallel output register, ideal for applications in multiple control, low power control and data acquisition systems. The latch is designed to be tolerant of up to 5V and has an open drain configuration. It has a single input line and supports both system and asynchronous clear. Its operations make it suitable for fast, reliable operations within various types of control and data acquisition systems.
