SN74HCT652DWE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HCT652DWE4 is an octal bus transceiver and register with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V. The device features independent output enable inputs (OEAB and OEBA) and selection control inputs (SAB and SBA) for managing data flow between two buses. It supports both real-time transmission and stored data modes, allowing direct multiplexing of data or storage in internal D-type flip-flops. The component provides low input current and compatibility with TTL voltage levels.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the package type matches design requirements, typically SOIC-24 for this series. Ensure voltage levels align with system specifications, strictly adhering to the 4.5 V to 5.5 V operating range. Cross-reference datasheets for pinout consistency and electrical characteristics before integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal bidirectional data transfer with optional latching capability. It is suitable for applications needing independent control over data direction and storage states. Consider the propagation delay and output drive strength relative to load requirements. Ensure power supply stability within the specified HCT voltage range to maintain signal integrity and timing performance.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74HCT652 family of registered bus transceivers. It shares functional similarities with other octal transceivers but offers integrated storage via D-type flip-flops. The HCT logic family ensures compatibility with standard TTL inputs while operating at higher speeds than older LS series devices. Variants may differ in packaging or environmental compliance, such as the E4 suffix indicating specific manufacturing attributes.
