74F673ASPC

Overview

The onsemi 74F673ASPC is a 16-bit Serial-In, Serial/Parallel-Out shift register housed in a 24-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide. It integrates a 16-bit serial I/O shift register and a 16-bit parallel-out storage register with a common serial data I/O pin. The device operates within a supply voltage range of +4.5V to +5.5V and supports an ambient temperature range of 0°C to +70°C. Key electrical characteristics include a maximum clock frequency of 85 MHz at the specified operating conditions.

Feature Summary

• Features a single pin that functions as either a serial input or a 3-STATE serial output.
• Includes a separate clock mechanism to transfer shift register contents to the storage register for parallel outputting.
• Supports recirculating serial shifting and recirculating parallel transfer modes.
• Provides an asynchronous master reset input to force storage register outputs LOW.

Applications

• Serial-to-parallel data conversion
• Recirculating shift register operations
• Parallel loading from storage register to shift register

Procurement Notes

Verify the specific package variant N24C corresponds to the 0.300 inch wide PDIP form factor. Confirm RoHS compliance status through official documentation. Check for end-of-life or obsolescence notices as this component originates from legacy Fairchild Semiconductor manufacturing lines now managed by onsemi. Ensure supply chain authenticity given the historical nature of the part number.

Selection Notes

Select this component when a 16-bit serial-in, parallel-out configuration is required with a slim DIP footprint. It is suitable for applications needing a common serial I/O pin and recirculation capabilities. Consider the 0°C to +70°C operating temperature range and 4.5V to 5.5V supply voltage constraints. Evaluate if the 24-pin PDIP package fits the mechanical design requirements compared to SOIC alternatives.

Part Context

This device belongs to the 74F series logic family, known for high-speed performance. The 74F673A variant specifically provides 16-bit shift register functionality. The 'SPC' suffix indicates the specific plastic dual-in-line package style. This part represents a legacy standard logic component originally manufactured by Fairchild Semiconductor.

Replacement Considerations

The 74F673ASC is available in a 24-Lead Small Outline Integrated Circuit (SOIC) package. The 74F673APC is offered in a 24-Lead Plastic Dual-In-Line Package with a 0.600 inch width. Verify pinout compatibility and package dimensions before substituting these variants.
