Logic - Latches

The SN74ACT373PWRG4 is an octal transparent latch integrated circuit (IC). It is a device which stores binary information and is used to control access to and from a system\'s memory or other protection and authorization data. The SN74ACT373PWRG4 is a type of logic latch and is most commonly used to store and retrieve data in a state for a period of time. It is also commonly used for memory protection.

Application Field

The SN74ACT373PWRG4 is used in many different application fields, including telecommunications, metering, industrial control and automation, automotive and home appliances. In telecommunications, it is used as an analog-to-digital converter, while in metering it serves as a buffer in an energy meter. In industrial control and automation, the device is used to control access to data. In automotive and home applications, it is used as a digital thermometer for temperature control. Additionally, this device can be used for soil moisture measurement, as a remote display in agricultural systems, and for analog signal conditioning in a wide range of applications.

Working Principle

The SN74ACT373PWRG4 employs a latch-type structure, which can hold a signal, address, or digital input until a reset command is applied. The signal is stored inside a master latch, while the output is controlled by an enable signal. The enable signal is used to control access to the master latch and the signal stored in it. When the enable signal is applied, the integrated circuit (IC) will store the signal or address in the master latch. Once the enable signal is removed, the signal or address is locked in the master latch and is available at the device\'s output. The master latch can be cleared by applying a reset signal.

The SN74ACT373PWRG4 is mostly used in medium-speed logic circuits and provides a low propagation delay and high performance. It also has a quiescent supply current of less than 500µA, making it an efficient device. The device operates within a wide temperature range of -40 to +85 degrees Celsius and a power supply voltage range of 3.6 to 5.5 volts.

The SN74ACT373PWRG4 is a highly reliable device with an integrated power-down feature that allows it to protect against short-circuits and to reduce power consumption when not in use. This device is also packed inside a space-saving, small DIP package, making it easy to integrate into any system.

In summary, the SN74ACT373PWRG4 is a versatile logic latch IC which is used in many different application fields. It is mostly used to store and retrieve data in a state for a period of time. Its low propagation delay and quiescent supply current make it an ideal device for medium-speed logic applications, while its integrated power-down feature provides an additional level of protection and power savings when the device is not in use.
