ON Semiconductor MC74HC573ADTG Octal 3-State Non-Inverting Latch

The MC74HC573ADTG is a high-performance, octal 3-state non-inverting latch designed by ON Semiconductor, a leader in energy-efficient innovations. This integrated circuit is part of the high-speed CMOS family and is fabricated with silicon gate CMOS technology. It offers a robust and reliable solution for a wide range of digital applications that require latching capabilities to maintain data integrity.

Featuring a latch enable (LE) and output enable (OE) control, the MC74HC573ADTG allows data on its eight input pins (D0 to D7) to be captured and held on the output pins (Q0 to Q7) when LE is held high and OE is held low. The outputs can be placed in a high-impedance state, which is essential for interfacing with bus-oriented systems, by setting OE high, regardless of the status of LE.

This device is characterized for operation from -55°C to +125°C, making it suitable for extreme environments and ensuring reliable performance across a wide temperature range. Its pin configuration is thoughtfully designed in a 20-lead TSSOP package, providing a compact footprint for space-constrained applications.

The MC74HC573ADTG latch is designed to directly interface with the TTL family and other speed CMOS logic, supporting a wide range of supply voltages from 2V to 6V. Its low power consumption and high noise immunity are hallmarks of CMOS technology, making it an efficient choice for power-sensitive applications.

With its fast propagation delays and minimal power dissipation during quiescent conditions, the MC74HC573ADTG is a versatile component for implementing memory registers, buffer registers, and control registers. Its robust latch function ensures that data is maintained stably, providing designers with a reliable tool for data storage and transfer tasks in complex digital systems.

Overall, the ON Semiconductor MC74HC573ADTG octal 3-state non-inverting latch represents a blend of performance, efficiency, and reliability, making it a preferred choice for electronic engineers and designers looking to enhance their digital designs.
