74ACT652SC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACT652SC is an octal bus transceiver and register IC housed in a 24-lead SOIC package. It integrates independent D-type flip-flops for the A and B buses, enabling multiplexed transmission of real-time data or stored register content. The device operates within a supply voltage range of 4.5V to 5.5V and supports temperatures from -40°C to +85°C. Key electrical specifications include a maximum clock frequency of 50 MHz, propagation delays ranging from 2.0 ns to 10.5 ns depending on the signal path, and output drive capabilities sourcing or sinking 24 mA.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Independent registers for A and B buses allow simultaneous storage and retrieval of data without interference between channels.
• Multiplexed real-time and stored data transmission enables flexible bus management by selecting between direct input signals and internal register outputs.
• TTL-compatible inputs ensure compatibility with standard logic families while maintaining high-speed performance characteristics.

Buffers, Drivers, Receivers, Transceivers Applications

• Bus interface circuits requiring bidirectional data transfer with optional latching capability
• Memory systems utilizing multiplexed address and data lines
• Digital control systems managing multiple peripheral devices via shared bus architectures

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm packaging type, as the base part number may be available in tape and reel formats when appending the letter X. Confirm that the component meets RoHS compliance requirements if restricted substances are mandated for your assembly process. Ensure the selected package variant matches your PCB footprint design constraints prior to procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring both immediate data transparency and temporary storage on dual buses. The ACT series offers faster switching speeds compared to standard HC/HCT logic. Consider the 24 mA output drive strength for driving moderate capacitive loads directly. Evaluate the 24-pin package options against available board space and thermal dissipation needs.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the FACT (Fast Advanced CMOS Technology) family, designed for high-speed digital applications. It combines the speed of advanced CMOS technology with TTL-compatible input levels. The 74ACT652 specifically addresses applications needing robust bus isolation and data retention capabilities within a compact integrated circuit form factor.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes may include other octal bus transceivers with register functionality from the same logic family. Verify pinout compatibility and electrical characteristics such as propagation delay and output current before substitution. Cross-reference with manufacturer-specific equivalents that maintain the same 24-lead SOIC package dimensions.
