74ACT652SPC

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74ACT652SPC is an 8-bit registered bus transceiver housed in a 24-pin SOIC package. It integrates D-type flip-flops with control circuitry to allow multiplexed transmission of data directly from the input bus or from internal registers. The device features independent output enable pins for each direction and supports bidirectional data flow. Data is clocked into the registers when the appropriate clock pin reaches the HIGH logic level, providing flexible interface capabilities for digital systems requiring both immediate and stored data transfer.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Multiplexed real-time and stored data transmission via integrated D-type flip-flops
• Independent control of output enable for each data direction
• Bidirectional bus transceiver architecture with dedicated register storage

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed data buffering between microprocessors and peripheral devices
• Memory interface circuits requiring registered data latching
• Bidirectional communication buses in embedded systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'SPC' against official Fairchild/ON Semiconductor documentation to confirm the exact package variant and tape-and-reel specifications. Ensure compatibility with existing PCB footprints by cross-referencing the SOIC-24 dimensions. Confirm RoHS compliance status if required for your manufacturing process, as legacy part numbers may have varying environmental certifications depending on the production batch.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require simultaneous direct bus passing and registered data storage within a single IC. It is suitable for applications needing independent direction control without external gating logic. Consider the ACT series speed and drive characteristics relative to your system voltage levels. Verify that the 24-pin SOIC package fits your assembly constraints before finalizing the design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ACT logic family, which offers high-speed performance comparable to LS-TTL but operates at lower voltages. The 652 designation specifically identifies it as a registered bus transceiver. Fairchild Semiconductor has been integrated into ON Semiconductor, so current datasheets and ordering information should be referenced through ON Semi's official channels to ensure accurate product lifecycle and support status.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for equivalents such as the 74FCT652 for faster CMOS technology or the 74LCX652 for low-voltage applications. Ensure that any substitute maintains the same 8-bit width, registered functionality, and bidirectional control scheme. Verify pinout compatibility to avoid redesigning the printed circuit board.
