ON Semiconductor MC74HC589ADR2 Product Overview

The MC74HC589ADR2 is a high-performance integrated circuit designed and manufactured by ON Semiconductor, a leading name in the semiconductor industry. This device is a part of the high-speed CMOS family and is particularly known for its 8-bit serial or parallel-input/serial-output shift register with 3-state output capabilities.

The MC74HC589ADR2 is designed to interface with the high-speed requirements of system expansion in microprocessor and microcomputer-based systems. It is capable of working with clock frequencies up to 25 MHz, which makes it suitable for fast data processing applications. Its low power consumption and high noise immunity are derived from the MOS technology that makes this device reliable and efficient for a wide range of applications.

This shift register features two modes of operation: serial (shift right) and parallel. In serial mode, data is entered serially and shifted right with each clock pulse, which is ideal for applications requiring serial data input or output, such as data acquisition systems or communication interfaces. In parallel mode, the device allows for 8-bit data to be loaded simultaneously, which is useful for interfacing with parallel buses in microprocessors and digital systems.

The MC74HC589ADR2 comes in a compact SOP-16 package, making it easy to integrate into a variety of electronic circuits. The device operates over a broad voltage range from 2V to 6V, providing the flexibility to be used in both TTL and CMOS environments. Its 3-state outputs allow for direct connection to a bus-organized system, preventing bus contention issues by placing the output in a high-impedance state when not in use.

ON Semiconductor's commitment to quality ensures that the MC74HC589ADR2 meets stringent standards for performance and durability. This shift register is ideal for applications that require reliable data transfer, such as data loggers, digital signal processing, and control systems, making it a versatile component for both commercial and industrial markets.

With its combination of speed, power efficiency, and robustness, the MC74HC589ADR2 from ON Semiconductor is an excellent choice for designers looking to enhance their digital systems with a reliable and high-performing shift register.
