SN74AVC2T45DCTR

Translators, Level Shifters Overview

The SN74AVC2T45DCTR is a dual-bit, dual-supply bus transceiver manufactured by Texas Instruments. It facilitates asynchronous communication between two independent data buses operating at different voltage levels. The device features configurable level-shifting capabilities, allowing A and B ports to track their respective VCCA and VCCB supply rails within the 1.2V to 3.6V range. This architecture supports universal low-voltage bidirectional translation across various standard voltage nodes including 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. The component utilizes a NanoFree™ package for compact surface-mount integration.

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'DCTR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the device meets RoHS3 compliance standards if environmental regulations apply to the manufacturing site. Ensure the selected variant aligns with the required thermal performance and moisture sensitivity level specifications for the intended production environment.

Translators, Level Shifters Selection Notes

Select this component when designing systems requiring bidirectional data transfer between logic families operating at distinct supply voltages within the 1.2V to 3.6V window. The dual-supply architecture allows flexible voltage node selection without external level-shifting circuits. Consider the maximum data rate requirements relative to the specific voltage differential between the A and B ports to ensure signal integrity.

Translators, Level Shifters Part Context

This part belongs to the SN74AVC2T45 family of voltage level translators from Texas Instruments. It is designed for high-speed asynchronous communication between buses with different voltage domains. The device integrates direction control logic to manage data flow between the A and B ports, ensuring proper signal routing based on the DIR pin state while maintaining electrical isolation between the separate power supplies.
