MM74HC594MX

Shift Registers Overview

The MM74HC594MX is an 8-bit serial-in, parallel-out shift register with output registers manufactured by onsemi. It utilizes advanced silicon-gate CMOS technology and operates within a supply voltage range of 2V to 6V. The device features separate clocks for the shift and storage registers, along with direct overriding clears. It supports cascading via a serial output pin and guarantees a shift frequency up to 30 MHz at 4.5V. The component is housed in a 16-lead SOIC package (M16A) and is designed for surface mount installation.

Shift Registers Feature Summary

• Contains an 8-bit serial-in, parallel-out shift register feeding an 8-bit D-type storage register
• Features separate positive-edge triggered clocks and direct overriding clears for both registers
• Provides high noise immunity and low power consumption typical of standard CMOS integrated circuits
• Capable of driving 15 LS-TTL loads while maintaining compatibility with the 74LS logic family

Shift Registers Applications

• Data acquisition systems requiring serial-to-parallel conversion
• LED display drivers utilizing cascaded shift register configurations
• Industrial control interfaces for expanding I/O capabilities
• Communication equipment managing data buffering and transfer

Shift Registers Procurement Notes

Verify the specific ordering suffix 'X' confirms the tape and reel packaging format required for automated assembly processes. Confirm that the manufacturer designation aligns with current corporate structures following industry acquisitions. Ensure compliance with RoHS directives and verify the operating temperature range meets the specific environmental requirements of the target application design.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with independent storage latching is required. The MM74HC594MX offers speed and function compatibility with the 74LS logic family, facilitating direct upgrades from older designs. Consider the wide operating voltage range and static discharge protection features for robust performance in noisy environments or varying power conditions.

Shift Registers Part Context

This part belongs to the MM74HC series of high-speed CMOS logic devices produced by onsemi. The MM74HC594 specifically addresses applications needing serial data expansion with parallel output availability. It represents a standard solution for digital logic interfacing where data serialization and storage are critical functions within larger electronic systems.

Shift Registers Replacement Considerations

Compatible substitutes include the MM74HC594M and MM74HC594N variants, which share identical logical functionality but differ in physical packaging formats such as SOIC or PDIP.
