74ACT652SC

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74ACT652SC is an octal registered bus transceiver housed in a 24-pin SOIC package. It integrates D-type flip-flops with control circuitry to enable multiplexed transmission of data directly from the input bus or from internal registers. The device supports bidirectional data flow between two ports, featuring independent output enable controls for each direction. It operates within a voltage range of 4.5V to 5.5V and provides outputs capable of sourcing and sinking 24 mA.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Multiplexed real-time and stored data transmission via integrated D-type flip-flops
• Independent registers for A and B buses allowing separate data storage
• Independent output enable pins (OEAB, OEBA) for directional control

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented applications requiring registered data transfer
• Systems needing multiplexed transmission of real-time and stored data
• Bidirectional interface circuits with independent direction control

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm pinout compatibility and electrical characteristics. Ensure the component meets current environmental standards such as RoHS if required by your design specifications. Cross-reference the datasheet revision date to confirm the accuracy of timing parameters and operating conditions before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal registered bus transceiver with independent direction control is required. It is suitable for designs utilizing the 74ACT logic family that need both immediate bus passing and registered data storage capabilities. Consider the 24mA drive strength and 24-pin SOIC packaging constraints during board layout and thermal management planning.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ACT series of high-speed CMOS logic devices manufactured by Fairchild Semiconductor. The ACT series combines the speed of AC logic with TTL-compatible inputs. The 74ACT652SC specifically addresses applications requiring bidirectional data transfer with optional registration, distinguishing it from non-registered transceivers like the 74ACT245.
