MC74HC595AFL2

Shift Registers Overview

The MC74HC595AFL2 is an 8-bit serial-input, serial or parallel-output shift register with latched 3-state outputs manufactured by onsemi. It comprises an 8-bit shift register and an 8-bit D-type latch. The device operates within a voltage range of 2.0 V to 6.0 V and features low input current of 1.0 μA. It provides high noise immunity characteristic of CMOS devices and interfaces directly with SPI serial data ports on CMOS MPUs and MCUs. The component is housed in a 16-lead SSOP package.

Shift Registers Feature Summary

• Integrates an 8-bit shift register and an 8-bit D-type latch with independent clock inputs for flexible data handling.
• Features asynchronous reset capability for the shift register to control data state.
• Provides 3-state parallel outputs that can directly interface with CMOS, NMOS, and TTL loads.

Shift Registers Applications

• Serial-to-parallel data conversion in microprocessor systems
• SPI interface expansion for CMOS MPUs and MCUs
• Display driver circuits requiring latched parallel outputs

Shift Registers Procurement Notes

Verify the specific suffix FL2 against the official onsemi datasheet to confirm the package type and tape/reel specifications. Ensure the order quantity matches the manufacturer's minimum packaging requirements. Confirm RoHS compliance status as defined in the latest product documentation before finalizing procurement.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with latched outputs is required for SPI-based systems. It is suitable for designs needing direct interfacing with standard logic families. Verify that the operating voltage range of 2.0 V to 6.0 V aligns with the system power supply. Consider the SSOP package constraints for PCB layout.

Shift Registers Part Context

This part belongs to the MC74HC595A family of silicon-gate CMOS logic devices. It represents an improvement over the standard HC595 with lower quiescent power and improved propagation delays. The family is designed for high-speed digital applications requiring reliable serial data shifting and parallel storage capabilities.

Shift Registers Replacement Considerations

Check for compatible parts such as MC74HC595ADR2G or MC74HC595AMNTWG from onsemi. Verify pin compatibility and electrical parameters before substitution. Other manufacturers' 74HC595 equivalents may be used if they meet the same voltage and speed requirements.
