SN74LVC2T45DCTT

Translators, Level Shifters Overview

The SN74LVC2T45DCTT is a dual-bit, dual-supply bus transceiver from Texas Instruments' LVC logic series. It facilitates asynchronous communication between two data buses with configurable voltage-level shifting. The device operates with independent power rails: VCCA and VCCB both support voltages ranging from 1.65V to 5.5V. It features three-state outputs and bidirectional data transfer controlled by a Direction (DIR) input. Key electrical parameters include a maximum propagation delay of 17.7 ns, a maximum supply voltage of 5.5V, and a minimum of 1.65V. The component supports a maximum data rate of 420Mbps when converting between 3.3V and 5V nodes.

Translators, Level Shifters Feature Summary

• Configurable dual-rail design allowing independent operation of ports across the full 1.65V to 5.5V range
• Bidirectional data transfer capability enabled by a single Direction control input for asynchronous bus communication
• Supports partial power-down mode via Ioff circuitry to prevent backflow current during low-power states
• High electrostatic discharge protection performance exceeding JESD 22 requirements for robust system reliability

Translators, Level Shifters Applications

• Personal electronics interface connections
• Industrial control systems requiring mixed-voltage signal translation
• Enterprise infrastructure equipment
• Telecommunications network devices

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'TT' corresponds to the SM-8 package variant as documented in official Texas Instruments datasheets. Confirm RoHS compliance status and ensure the ordering information matches the required tape-and-reel or cut-tape packaging format. Cross-reference the manufacturer part number against the latest product selection guide to validate availability and manufacturing lifecycle status before finalizing procurement.

Translators, Level Shifters Selection Notes

Select this component when designing systems requiring bidirectional level shifting between voltage domains within the 1.65V to 5.5V range. Ensure the application demands a dual-channel configuration suitable for parallel data buses. Verify that the operating temperature range of -40°C to +85°C aligns with the environmental conditions. Consider the SM-8 package dimensions for PCB layout constraints and confirm that the 3-state output characteristics meet the bus termination requirements.
