SN74AXC2T45QDCURQ1

Translators, Level Shifters Overview

The SN74AXC2T45QDCURQ1 is an automotive-grade, two-bit noninverting translating bus transceiver featuring configurable dual-rail power supplies. It supports asynchronous communication between data buses with supply voltages ranging from 0.65V to 3.6V on both VCCA and VCCB ports. The device achieves up to 380Mbps data rates when translating between 1.8V and 3.3V levels. It includes glitch-free power sequencing, VCC isolation for high-impedance states below 100mV, and Ioff support for partial-power-down modes. Operating temperatures span from -40°C to +125°C within an 8-pin VSSOP package.

Translators, Level Shifters Feature Summary

• Fully configurable dual-rail design allows independent operation of each port across a wide voltage range.
• Glitch-free power supply sequencing ensures robust performance during power-on or power-off events.
• VCC isolation feature disables outputs and enters high-impedance state if either supply drops below 100mV.
• Ioff protection circuitry prevents excessive current draw during partial-power-down applications.

Translators, Level Shifters Applications

• Enterprise and communications systems
• Industrial control equipment
• Personal electronics devices
• Wireless infrastructure components
• Building automation networks

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix matches the required package type and tape-and-reel specifications. Confirm that the AEC-Q100 qualification status aligns with automotive reliability requirements. Ensure the DCU package variant corresponds to the intended PCB footprint and thermal management strategy. Cross-reference the datasheet revision date to confirm compatibility with existing design documentation.

Translators, Level Shifters Selection Notes

Select this component for designs requiring bidirectional level shifting between disparate low-voltage logic families. The dual-supply architecture accommodates complex power domains without fixed translation ratios. Evaluate propagation delay variations across different voltage combinations to ensure timing margins are met. Consider the Ioff capability if the system requires safe disconnection during standby modes.

Translators, Level Shifters Part Context

This part belongs to the SN74AXC2T45-Q1 family of translating transceivers designed for automotive environments. It shares functional similarities with other LVC and AVC series devices but offers extended voltage flexibility down to 0.65V. The Q1 suffix denotes automotive qualification, distinguishing it from standard commercial variants while maintaining pin compatibility within the same logical family.

Translators, Level Shifters FAQ

How does the VCC isolation feature function?

If either VCCA or VCCB input falls below 100mV, all I/O outputs are disabled and enter a high-impedance state to prevent unintended signal transmission.

What is the maximum data rate supported?

The device supports up to 380Mbps when translating signals between 1.8V and 3.3V supply levels.
