ON Semiconductor MC74HC573AN Octal 3-State Non-Inverting Latch

The MC74HC573AN is a high-performance, octal 3-state non-inverting latch manufactured by ON Semiconductor, designed to integrate seamlessly into a wide range of digital applications. This device features eight latches with three-state outputs for bus organized system applications. The MC74HC573AN is fabricated with silicon gate CMOS technology which ensures that it has the high noise immunity and low power consumption characteristic of CMOS integrated circuits, along with the ability to drive 15 LSTTL loads.

The octal latch operates as a transparent latch when the Latch Enable (LE) input is high, and data on the D inputs are latched. When LE is low, the latched outputs remain stable and unaffected by changes on the data inputs. Furthermore, the Output Enable (OE) input can be used to place the eight outputs into either a normal logic state (high or low logic levels) or the high-impedance state. In the latter mode, the outputs neither load the bus nor drive it, effectively isolating the bus. This makes the MC74HC573AN ideal for bus-oriented applications.

The MC74HC573AN is capable of operating with a wide power supply range from 2V to 6V, providing a versatile power management scheme. This flexibility makes it suitable for interfacing with both standard and non-standard logic families. The device also provides significant protection against static discharge, ensuring reliability and longevity in operation.

Encased in a standard 20-pin DIP package, the MC74HC573AN is easy to integrate into various types of electronic assemblies. Its pin configuration is industry-standard, which ensures compatibility with a broad range of PCB layouts and designs. ON Semiconductor's commitment to quality means that the MC74HC573AN is designed for optimal performance in digital logic systems and is a reliable choice for designers looking to implement latches in their circuits.

In summary, the MC74HC573AN from ON Semiconductor is a versatile, high-performance octal latch that is essential for designers who require a reliable solution for managing data flow in digital systems. Its CMOS technology, wide operating voltage range, and bus-friendly interface make it an ideal choice for a multitude of digital applications.
