74F675ASPC

Overview

The Fairchild Semiconductor 74F675ASPC is a 16-bit serial-in/serial-out shift register with a parallel-output storage register, part of the F/FAST series. It operates on TTL logic levels and features true output polarity. The device is housed in a 24-lead Plastic Dual-In-Line Package (PDIP) with a 0.300-inch slim profile. It supports right-direction shifting and includes hold mode functionality. The component is designed for through-hole mounting and functions within a standard voltage range.

Feature Summary

• Integrates a 16-bit serial-in/serial-out shift register with a separate 16-bit parallel-output storage register
• Supports right-direction data shifting with true output polarity
• Includes hold mode capability to maintain stored data states

Applications

• Data buffering in digital communication systems
• Serial-to-parallel conversion interfaces
• General-purpose shift register applications in TTL-based logic circuits

Procurement Notes

Verify RoHS compliance status as the component is listed as non-compliant in available records. Confirm package dimensions match the 24-lead PDIP specification. Check manufacturer documentation for obsolescence status, as this part may be discontinued. Ensure sourcing channels provide authentic Fairchild Semiconductor products to avoid counterfeit components.

Selection Notes

Select this component when a 16-bit shift register with parallel output storage is required in a DIP package. Consider the F/FAST series speed characteristics for TTL applications. Verify that the 24-pin footprint fits the target PCB layout. Evaluate if the hold mode feature meets system data retention requirements.

Part Context

This device belongs to the Fairchild 74F series, known for high-speed CMOS-compatible logic. The 74F675A variant specifically provides serial input capabilities with parallel output storage. It is distinct from similar parts like the 74F676 by its specific input/output configuration and storage register integration.

Replacement Considerations

Check for direct substitutes such as the 74F675APC or 74F675ASC from the same manufacturer family. Verify pin compatibility and electrical specifications before substitution. Note that some variants may have different packaging or compliance statuses.
