SN74LVTH652DWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH652DWR is an octal bus transceiver and register designed for low-voltage 3.3-V VCC operation with TTL interface capability to 5-V systems. It integrates bus-transceiver circuits, D-type flip-flops, and control circuitry for multiplexed data transmission from the bus or internal registers. The device features independent output-enable inputs (OEAB, OEBA) and select-control inputs (SAB, SBA) to manage real-time versus stored data transfer. It supports hot-insertion via Ioff and power-up 3-state functionality, ensuring outputs remain high-impedance during power transitions. Active bus-hold circuitry maintains valid logic levels on floating inputs without external resistors.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Integrates octal bus transceivers with D-type flip-flops for multiplexed data transmission between buses A and B.
• Supports mixed-mode signal operation by providing a TTL interface to 5-V system environments while operating at 3.3 V.
• Features active bus-hold circuitry to maintain valid logic levels on unused or floating data inputs.
• Includes Ioff and power-up 3-state support to prevent damaging current backflow and driver conflicts during hot insertion.

Buffers, Drivers, Receivers, Transceivers Applications

• Multiplexed transmission of data directly from data buses or internal storage registers
• Mixed-mode signal operation connecting 3.3-V devices to 5-V system environments
• Hot-insertion applications requiring controlled power-up states

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant against the datasheet ordering information, as suffixes denote different physical packages such as SOIC, TSSOP, or SSOP. Confirm that the 'R' suffix indicates tape-and-reel packaging if applicable to your assembly process. Ensure the component meets RoHS compliance requirements for your manufacturing standards. Cross-reference the manufacturer part number with official distributor catalogs to validate authenticity and current production status before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring simultaneous bus interfacing and data latching in a single package. It is suitable for applications needing independent control over data direction and storage selection. Consider its compatibility with 3.3-V logic families and its ability to interface with 5-V inputs. Evaluate the need for active bus-hold features to simplify input conditioning. Ensure the operating temperature range aligns with the intended environmental conditions of the final application.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments LVTH logic family, which is optimized for low-voltage operations. It combines the functionality of a standard octal bus transceiver with integrated D-type flip-flops, allowing for flexible data management. The DW suffix specifically identifies the Small Outline Integrated Circuit (SOIC) package type, distinguishing it from other form factors like TSSOP or SSOP within the same functional family.
