SN74LVTH2952DBRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH2952DBRG4 is an octal bus transceiver and register manufactured by Texas Instruments. It operates at a supply voltage of 2.7 V to 3.6 V and supports mixed-mode signal operation with 5-V tolerant inputs and outputs. The device contains two 8-bit back-to-back registers for bidirectional data storage, controlled by clock (CLK), clock-enable (CLKEN), and output-enable (OE) signals. It features active bus-hold circuitry on data inputs, eliminating the need for external pullup or pulldown resistors. The component provides Ioff and power-up 3-state support for hot-insertion applications.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation with 5-V input and output voltages while operating at 3.3-V VCC
• Contains two 8-bit back-to-back registers that store data flowing in both directions between two bidirectional buses
• Features active bus-hold circuitry on data inputs to maintain valid logic levels without external resistors
• Provides Ioff and power-up 3-state capabilities to prevent damaging current backflow during hot insertion

Buffers, Drivers, Receivers, Transceivers Applications

• Hot-insertion applications requiring bus isolation
• Bidirectional data storage and transfer between 3.3-V and 5-V system environments
• Octal bus transceivers and registers in mixed-mode signal systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'RG4' against the manufacturer's official documentation to confirm compliance with RoHS standards and lead-free specifications. Ensure the package type matches the required PCB footprint, as this part number corresponds to the TSSOP-24 configuration. Cross-reference the full part number with the latest TI datasheet to validate availability and confirm it aligns with your design's temperature range and electrical requirements.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require bidirectional data flow between buses operating at different voltage levels, specifically 3.3 V and 5 V. The integrated bus-hold feature simplifies board layout by removing the need for external pullup or pulldown resistors. Consider this device for applications involving hot-swapping or hot-insertion due to its built-in power-up 3-state and Ioff protection mechanisms.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the LVTH logic family from Texas Instruments, designed for low-voltage operations. It functions as an octal bus transceiver with registered outputs, allowing data latching on clock transitions. The DB package variant indicates a small-outline package configuration suitable for surface-mount assembly. It is part of a broader series of bus transceivers intended for high-density digital interfaces.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Consult the manufacturer's official replacement guide for verified substitute part numbers. Ensure any alternative maintains compatibility with 3.3-V to 5-V mixed-signal environments and offers equivalent pinout and functional characteristics.
