MC74HC597ADR2G

Shift Registers Overview

The MC74HC597ADR2G is an 8-bit serial or parallel-input/serial-output shift register with an input latch, manufactured by onsemi. It utilizes high-performance silicon-gate CMOS technology and operates within a supply voltage range of 2.0 V to 6.0 V. The device features a SOIC-16 package and supports an operating temperature range from -55°C to +125°C. It provides output drive capability for 10 LSTTL loads and includes asynchronous active-low reset functionality.

Shift Registers Feature Summary

• Integrates an 8-bit input latch that feeds parallel data to an 8-bit shift register, allowing simultaneous parallel loading and serial shifting operations.
• Outputs are directly compatible with CMOS, NMOS, and TTL logic families, ensuring broad interface versatility.
• Features low input current consumption and high noise immunity characteristic of standard CMOS devices.
• Includes an asynchronous active-low reset input that clears the shift register without affecting the data stored in the input latch.

Shift Registers Applications

• Parallel-to-serial data conversion in communication systems
• Serial-to-parallel data expansion for I/O port extension
• Display driver circuits requiring multiplexed output control
• Digital signal processing interfaces needing data buffering

Shift Registers Procurement Notes

Verify the specific ordering suffix 'R2G' corresponds to the SOIC-16 tape and reel packaging configuration as defined in the manufacturer's ordering information. Confirm RoHS compliance status through official material composition documents. Ensure the procurement channel sources genuine components matching the MC74HC597A/D datasheet specifications to guarantee electrical performance and reliability standards.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with a dedicated input latch is required for mixed-voltage logic environments. The HC series compatibility allows operation across a wide voltage range suitable for various digital systems. Consider the SOIC-16 package dimensions for PCB layout constraints. Verify that the required clock frequencies and propagation delays align with the AC electrical characteristics specified for the target operating voltage.

Shift Registers Part Context

This device belongs to the MC74HC597A family of high-speed CMOS logic integrated circuits. It shares pinout compatibility with LS597 devices while offering improved speed and lower power consumption typical of HC technology. The product line includes variations in packaging such as TSSOP-16 and QFN16, all maintaining identical functional pinouts and electrical characteristics for design flexibility.

Shift Registers Replacement Considerations

The MC74HC597ADG is a direct replacement variant available in a rail-packaged SOIC-16 format. Other manufacturers producing JEDEC-compliant 8-bit shift registers with latches may serve as alternatives if pinout and electrical parameters match exactly. Verify logic levels and package dimensions before substituting.
