SN74AVC2T45DCTT

Translators, Level Shifters Overview

The SN74AVC2T45DCTT is a dual-bit, non-inverting bus transceiver from the Texas Instruments 74AVC series. It operates with independent VCCA and VCCB supply rails ranging from 1.2V to 3.6V, enabling bidirectional voltage level translation between diverse logic nodes. The device features a propagation delay of 5.4 ns and supports data rates up to 500Mbps at 1.8V to 3.3V. It utilizes an SM-8 (MSOP) surface-mount package and functions within a temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Dual power rail design allows flexible voltage translation between 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V systems
• I/O pins provide 4.6V overvoltage tolerance for robust interface protection
• Supports local power-down mode via Ioff functionality to prevent excessive leakage current
• Direction control input manages data flow direction between A and B ports

Translators, Level Shifters Applications

• Smartphones and portable consumer electronics
• Server infrastructure and desktop computers
• Laptop systems requiring low-voltage interconnects
• General-purpose portable devices with mixed voltage domains

Translators, Level Shifters Procurement Notes

Verify the specific suffix DCTT corresponds to the MSOP-8 package and tape-and-reel or cut-tape availability. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering quantity matches the manufacturer's standard packaging configurations to avoid handling discrepancies.

Translators, Level Shifters Selection Notes

Select this component when interfacing between 1.2V and 3.6V logic families requiring high-speed bidirectional transfer. The AVCH/AVC series offers faster performance than LVC alternatives. Verify that the 4.6V I/O tolerance meets the maximum voltage levels of the connected buses. Consider the SM-8 footprint constraints during PCB layout planning.

Translators, Level Shifters Part Context

This part belongs to the Texas Instruments 74AVC family of voltage-level translators. It serves as a bridge for asynchronous communication between two data buses operating at different supply voltages. The device simplifies system design by eliminating external level-shifting components while maintaining signal integrity across varying voltage domains.

Translators, Level Shifters Replacement Considerations

SN74AVC2T45DCTR is the reel-packaged equivalent. SN74AVC2T45YZPR offers the same function in a DSBGA-8 package. SN74AVCH2T45DCTT provides similar performance in an SM-8 package.
