Overview
The SN74AVCH1T45DBVRE4 is a single-bit dual-supply bus transceiver from the Texas Instruments AVCH series, housed in a SOT-23-6 package. It supports voltage levels ranging from 1.2 V to 3.6 V on both ports A and B, enabling flexible level translation between different logic families. The device features configurable voltage translation capabilities with 3-state outputs and operates within an industrial temperature range of -40°C to +85°C.
Feature Summary
- Configurable voltage translation allows seamless interfacing between diverse logic families operating at different supply voltages.
- Dual-supply architecture provides independent power rails for Port A and Port B to accommodate varying system requirements.
- Bidirectional data flow capability ensures efficient signal transmission in both directions across the single channel.
Applications
- Interfacing low-voltage microcontrollers with higher-voltage peripheral devices
- Level shifting in portable battery-operated electronic equipment
- Signal translation in embedded systems requiring mixed-voltage logic integration
Procurement Notes
Verify the specific suffix 'E4' indicates lead-free compliance and RoHS standards when sourcing. Confirm the SOT-23-6 package availability matches your PCB footprint requirements. Ensure the operating temperature range aligns with your environmental conditions. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.
Selection Notes
Select this component when a single-channel bidirectional translator is needed for low-voltage applications. The AVCH series offers optimized performance for 1.2V to 3.6V systems compared to standard AVC variants. Consider the SOT-23-6 package size for space-constrained designs. Verify that the required data rate and propagation delay meet your system timing constraints before finalizing the selection.
Part Context
This part belongs to the SN74AVCH1T45 family of single-bit bus transceivers. It shares functional similarities with the SN74AVC1T45 but includes enhanced features for configurable voltage translation. The DBVR variant denotes the specific tape-and-reel packaging format suitable for automated surface-mount assembly processes.
Replacement Considerations
SN74AVCH1T45DBVT serves as a pin-compatible alternative in the same package. SN74AVC1T45DBVRG4 is a related variant within the broader AVC family offering similar functionality.
