SN74LVC1T45DBVRE4

Translators, Level Shifters Overview

The SN74LVC1T45DBVRE4 is a single-bit dual-supply bus transceiver from the Texas Instruments SN74LVC1T45 series. It operates within a supply voltage range of 1.65 V to 5.5 V on both ports, enabling bidirectional voltage level translation between various low-voltage nodes. The device features a propagation delay of 17.7 ns and supports data rates up to 420 Mbps. It utilizes a SOT-23-6 surface-mount package and functions across an operating temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Configurable dual-rail design allowing independent power supply settings for each port across the full voltage range
• Ioff support enables partial power-down mode by disabling outputs to prevent damaging current backflow
• Direction control input referenced to VCCA facilitates asynchronous communication between two data buses

Translators, Level Shifters Applications

• Bidirectional voltage level translation between different logic families
• Asynchronous communication interfaces between microcontrollers and peripherals
• Portable equipment requiring low-power operation and flexible voltage domains

Translators, Level Shifters Procurement Notes

Verify the RE4 suffix indicates specific tape-and-reel packaging configurations distinct from standard variants. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the component matches the exact SOT-23-6 footprint and pinout requirements of the target PCB layout.

Translators, Level Shifters Selection Notes

Select this component when a single-channel bidirectional translator is required for mixed-voltage systems. The LVC family offers compatibility with CMOS and TTL inputs while maintaining low quiescent current. Verify that the maximum data rate requirements align with the specific voltage conversion ratios in the application design.

Translators, Level Shifters Part Context

This part belongs to the SN74LVC1T45 family of single-bit bus transceivers. It shares functional characteristics with other members like the SN74LVC1T45DBVR but differs in packaging or reel specifications. The device serves as a bridge for interfacing digital components operating at different supply voltages within embedded systems.

Translators, Level Shifters Replacement Considerations

The SN74LVC1T45DBVR is a verified substitute offering identical electrical performance and functionality. Both parts share the same SOT-23-6 package and logical operations. Ensure the replacement variant meets the specific packaging quantity requirements of the manufacturing process.
