ON Semiconductor MC74AC573DWR2 Octal Latch

The MC74AC573DWR2 is a high-performance, octal transparent latch designed by ON Semiconductor, which is renowned for its expertise in power and signal management, logic, discrete, and custom devices. This integrated circuit (IC) is part of the advanced high-speed CMOS family and is fabricated with silicon gate CMOS technology to achieve operating speeds similar to LSTTL with the low power consumption of standard CMOS integrated circuits.

This octal latch has eight latches with three-state outputs for bus organized systems applications. It is capable of storing eight bits of data and comes in a wide-body SOIC-20 package, which provides a compact footprint while still being easy to handle in manufacturing and assembly processes.

The MC74AC573DWR2 is characterized for operation from -40°C to 85°C, making it suitable for industrial temperature ranges and ensuring reliable performance under varying environmental conditions. With a supply voltage ranging from 2V to 6V, it provides designers with flexibility in various applications and systems.

The device features a common latch enable (LE) input and a common output enable (OE) input. When LE is HIGH, data on the Dn inputs enter the latches. In this condition, the latches are transparent, i.e., a latch output will change each time its corresponding D-input changes. When LE is taken LOW, the latches store the information that was present on the D-inputs a setup time preceding the HIGH-to-LOW transition of LE. The OE input, when LOW, enables the outputs, allowing data from the latches to be presented on the output. When OE is HIGH, the outputs are in a high impedance state, which is ideal for interfacing with bus lines in a bus-organized system.

With its robust latch function, the MC74AC573DWR2 is an essential component for temporary storage of data, acting as a buffer for data that needs to be held stable during other operations. It is a versatile choice for a wide range of applications, including computers, telecommunications, instrumentation, and control systems where the additional capability of output control is desired.

ON Semiconductor's commitment to quality ensures that the MC74AC573DWR2 provides reliable and consistent performance for the most demanding electronic applications.
