74F675ASCX

Overview

The 74F675ASCX is a 16-bit serial-in, serial/parallel-out shift register manufactured by Fairchild Semiconductor. It operates within a voltage range of 4.5V to 5.5V and supports clock frequencies up to 85MHz. The device features tri-state outputs and is housed in a 24-pin Small Outline Integrated Circuit (SOIC) package.

Feature Summary

• Provides 16-bit data shifting capability with serial input and parallel output options
• Features tri-state outputs for bus-driven applications
• Supports high-speed operation with a maximum frequency of 85MHz

Applications

• Data storage and transfer in digital systems
• Parallel-to-serial conversion circuits
• High-speed logic interface modules

Procurement Notes

Verify the manufacturer designation, as this component is listed under both Fairchild Semiconductor and onsemi due to corporate acquisition history. Confirm the specific suffix 'X' indicates tape and reel packaging if required for automated assembly processes. Ensure compatibility with 5V logic levels before integration.

Selection Notes

Select this component when a 16-bit shift register with tri-state outputs is required. The SOIC-24 package suits surface-mount designs. Verify that the operating voltage range of 4.5V to 5.5V aligns with the system power supply. Consider the 85MHz speed limit for timing-critical applications.

Part Context

This part belongs to the 74F series of high-speed logic devices. The 74F675 variant specifically offers serial-in parallel-out functionality. The 'ASCX' designation typically denotes the automotive or extended temperature grade and tape-and-reel packaging format within the Fairchild/onsemi product line.

Replacement Considerations

Check for direct equivalents such as the 74F675A without the suffix if lead-free status differs. Verify pinout compatibility with other 16-bit shift registers in the 74F family before substitution.
