74AC648SPC

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74AC648SPC is an octal registered bus transceiver belonging to the AC series. It features eight D-type flip-flops with three-state outputs, designed for high-speed data transfer in bus-oriented applications. The device operates within a supply voltage range of 2V to 6V and utilizes a 24-pin Plastic Dual In-Line Package (PDIP). It provides true output polarity and includes direction control functionality.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal D-type flip-flop architecture with separate inputs for each stage
• Three-state outputs suitable for direct connection to system buses
• Direction control input manages data flow between ports

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented memory systems
• Registered interface circuits
• High-speed data buffering

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the package type matches the required 24-pin DIP configuration. Confirm the AC logic family specifications align with the target voltage levels. Ensure the manufacturer designation corresponds to Fairchild Semiconductor or its successor entity. Check RoHS compliance status if environmental regulations apply to the specific production batch.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal registered transceiver with three-state capability is required. The AC series offers higher speed than standard LS logic while maintaining CMOS power efficiency. Verify that the 2V to 6V operating range fits the system design constraints. Consider the PDIP package for through-hole mounting requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AC logic family, which represents advanced CMOS technology. It serves as a registered version of the non-registered 74AC646 bus transceiver. The device is functionally similar to other octal registers but adds bidirectional bus driving capabilities controlled by a direction pin.
