The SN74ACT573NSRE4 by Texas Instruments is a 8-bit latch with a separate clock. It is primarily designed and used in applications that need to store binary information on the go. The SN74ACT573NSRE4 can be used to store important digital data and retain it even when the power is turned down. These latches are also used to propel logic in communication systems, medical equipment, and other electronic applications.

Specifications

The SN74ACT573NSRE4 has a wide power supply range from 2.7 volts to 5.5 volts and a low power consumption. The SN74ACT573NSRE4 is also quite fast with a typical clock cycle time of 8 nanoseconds maximum. It has an operating temperature range from -55 degrees Celsius to 125 degrees Celsius and is available in an SOIC package.

Features

The SN74ACT573NSRE4 has several features which make it the go-to choice for many applications, the three most important of which are:

• TTL Compatible Inputs: The SN74ACT573NSRE4 is designed to accommodate standard TTL compatible inputs, allowing it to be used in a variety of applications.
• Power-up/down Latching: The SN74ACT573NSRE4 is designed to be power-up/down latch compatible, meaning it will still retain information even when the system is cycled on and off.
• Latency Control: The SN74ACT573NSRE4 provides latency control to reduce clock-to-output delay.

Working Principle

The SN74ACT573NSRE4 is a type of 8-bit latch with a separate clock port. It works by first taking in data input at the appropriate Logic level, i.e. a 0 or 1. When the latch is enabled, the data sent to the input will be sent to the output.

The output will maintain its current state, even when the input is changed, until the latch is disabled. The SN74ACT573NSRE4 latch is designed to be reset when the power is switched on and off, which is beneficial in applications where stability is necessary.

The SN74ACT573NSRE4 also features a separate clock pin which is used to control the latching operation. By synchronizing the latching operation to the clock edge, the overall power consumption of the system is minimized as well as reducing the risk of clock/data skew.

Applications

The SN74ACT573NSRE4 is primarily used in applications that require the storage of digital data or for controlling the flow of logic in communication systems. These applications can include medical equipment, storage systems, and other electronic systems.

The SN74ACT573NSRE4 is also used in battery backed-up systems where critical data must be retained even when power is switched off. As the SN74ACT573NSRE4 is a low power consumptive latch, it is also able to conserve precious power resources in these systems.

Conclusion

The SN74ACT573NSRE4 is a 8-bit latch with a separate clock that is primarily designed and used in applications that need to store binary information on the go. It has a wide power supply range and low power consumption, making it perfect for battery backed-up systems. The SN74ACT573NSRE4 is also used to propel logic in communication systems, medical equipment, and other electronic applications.
