SN74ABT573ADW

Logic latches are digital circuit components that store and maintain logic levels even when a device’s power is off. They are usually shown as a rectangle with two inputs and two outputs, labelled "D", "Q", "E" and "~Q". The SN74ABT573ADW is a type of single-pole double-throw (SPDT) latch, which uses one of two outputs to select one of two inputs, depending on the state of the Enable input.

The SN74ABT573ADW is a low-power, low-voltage CMOS Logic latch. It has two data inputs (“D” and “E”) and two outputs (“Q” and “~Q”). Both inputs (“D” and “E”) are level-triggered, meaning the signal must be held constant until the next input change, or until a device power cycle. When the latch is in its active state, “Q” will always be the complement of “~Q”; one will be high and the other will be low, so the latch functions in an “always active” mode.

The SN74ABT573ADW latch is designed for use in digital circuits and microcontrollers where access to data is needed on an intermittent basis, or where quick changes in the data are needed. It is a popular choice for certain simple control systems, such as infrared remotes, and is commonly used in communication devices, such as telephone systems, modems and digital video recorders. It can also be used in the primary stages of logic gates, as well as in any system that requires a device to store information.

The SN74ABT573ADW is a low-power, low-voltage CMOS Logic Device. It requires a supply voltage of 2.7 to 5.5 volts, and a very low power consumption of less than 20µA (in active mode), so it can be used in applications that have low space and power constraints. It also has exceptional noise immunity and ESD protection, making it suitable for use in troublesome and complex environments.

The SN74ABT573ADW latch works in two stages. The first stage is the setup stage, when the Enable input (“E”) is low, and the “D” input can be this and the other. When the Enable input is high, the outputs will switch, depending on the “D” input value. If the “D” input is high, the “Q” output will be high, and the “~Q” output will be low. If the “D” input is low, the “Q” output will be low and the “~Q” output will be high. Once the Enable input is changed to a low state, the latch will hold the previous output, and the information on the “D” input will be ignored until the Enable input is changed to a high state.

The SN74ABT573ADW latch is a simple and versatile logic device with a wide range of uses in digital logic designs. Its low power consumption and reliable operations make it a great choice for applications that require a quick and stable data storage solution. Its simple but effective triggering scheme ensures that the output will remain consistent and reliable, even in the most challenging of environments.
