SN74LVCH8T245DBQR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCH8T245DBQR is an 8-bit dual-supply bus transceiver from Texas Instruments, designed for configurable voltage translation between different logic families. It operates with VCCA ranging from 1.65V to 3.6V and VCCB from 1.65V to 5.5V, supporting bidirectional data flow. The device features three-state outputs and a common control pin for direction selection. Packaged in a 24-pin SSOP format, it functions within an industrial temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable voltage translation capability allows seamless interfacing between diverse logic voltage domains without external level-shifting components.
• Bidirectional data transfer architecture supports flexible system design by enabling data flow control via a single direction pin.
• Three-state output configuration facilitates connection to multiple buses or shared signal lines while minimizing power consumption during idle states.

Buffers, Drivers, Receivers, Transceivers Applications

• Mobile applications requiring low-voltage operation and high integration density
• Consumer electronics utilizing mixed-voltage logic interfaces
• Industrial instrumentation connecting sensors and controllers across different supply rails

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix DBQR against the manufacturer's official datasheet to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with RoHS directives and moisture sensitivity levels required for your assembly process. Cross-reference ordering information directly with Texas Instruments documentation to avoid discrepancies in lead times or packaging quantities.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require reliable translation between 1.8V, 2.5V, 3.3V, and 5V logic levels. Consider the SSOP package constraints regarding thermal dissipation and PCB space. Evaluate the propagation delay characteristics against your system's timing requirements to ensure signal integrity at intended operating frequencies.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVCH8T245 family of translating transceivers. It shares functional similarities with other LVC series devices but is optimized for low-voltage applications. The DBQR suffix specifically denotes the 24-SSOP package variant, distinguishing it from TSSOP or QFN alternatives within the same logical family.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include SN74LVCH8T245DWR and SN74LVCH8T245PWR, provided the package type change is acceptable for your layout. Verify pinout compatibility before swapping packages to prevent circuit damage.
