74F673APC

Overview

The Fairchild Semiconductor 74F673APC is a 16-bit Serial In Parallel Out (SIPO) shift register belonging to the F/FAST logic series. It features true outputs and operates in a right-shift direction. The device utilizes TTL logic levels and is housed in a 24-pin Plastic Dual In-line Package (PDIP). Key functional attributes include registered parallel outputs, read/write control capabilities, and a common serial I/O pin configuration.

Feature Summary

• Provides 16-bit serial-to-parallel data conversion with registered outputs
• Supports right-direction shifting with true output polarity
• Features read/write control for flexible data management
• Utilizes a common serial input/output pin architecture

Applications

• Parallel data expansion from serial sources
• Digital signal routing in TTL-based systems
• Data storage and buffering applications

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm package integrity and pin alignment against the 24-pin DIP specification. Ensure compatibility with existing TTL logic voltage levels and interface requirements before integration into circuit designs.

Selection Notes

Select this component when a 16-bit SIPO shift register with registered outputs is required. It is suitable for applications needing right-shift functionality and common serial I/O. Verify that the plastic DIP packaging meets mechanical constraints and that TTL input thresholds align with system logic levels.

Part Context

This part belongs to the 74F/FAST logic family, known for high-speed performance within standard TTL specifications. The 74F673 variant specifically addresses 16-bit serial-to-parallel conversion needs. It serves as a digital logic building block for data handling and transfer operations in electronic systems.

Replacement Considerations

Check for direct equivalents within the 74F673 family from other manufacturers. Verify pinout compatibility and electrical characteristics such as propagation delay and supply voltage range before substituting.
