SN74AVC2T45DCUR

Translators, Level Shifters Overview

The SN74AVC2T45DCUR is a dual-bit, non-inverting bus transceiver from the Texas Instruments SN74AVC2T45 series. It utilizes two independent configurable power rails (VCCA and VCCB) to facilitate bidirectional voltage level translation between logic domains operating at different voltages, such as 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. The device supports asynchronous communication with a propagation delay of 5.4 ns and operates within a supply voltage range of 1.2 V to 3.6 V for both ports. It features 3-state outputs and is housed in an 8-pin VSSOP package.

Translators, Level Shifters Feature Summary

• Dual independent power rail design enables flexible voltage level translation across multiple standard logic levels.
• Configurable direction control allows data transfer between A and B buses based on DIR pin logic state.
• I/O pins provide 4.6V overvoltage tolerance for robust operation in mixed-voltage systems.
• Supports local power-down mode via Ioff circuitry to prevent excessive leakage current during standby.

Translators, Level Shifters Applications

• Smartphones
• Servers
• Desktop computers and laptops

Translators, Level Shifters Procurement Notes

Verify the specific suffix DCUR corresponds to the VSSOP-8 package and tape-and-reel orientation required for your assembly line. Confirm RoHS compliance status and manufacturing origin through the official datasheet or Texas Instruments documentation before finalizing procurement specifications.

Translators, Level Shifters Selection Notes

Select this component when interfacing between low-voltage logic families requiring bidirectional translation with minimal propagation delay. Ensure the target application operates within the -40°C to +85°C temperature range and that the I/O voltage requirements do not exceed the specified 4.6V overvoltage tolerance limits.
