SN74AXC4T245PWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AXC4T245PWR is a 4-bit dual-supply bus transceiver from Texas Instruments' AXC logic family. It features configurable voltage translation and three-state outputs, supporting data rates up to 380 Mb/s when both supply voltages are at least 1.8 V. The device operates with independent VCCA and VCCB rails ranging from 0.65 V to 3.6 V. It utilizes a TSSOP-24 package and supports an extended industrial temperature range of -40°C to +125°C.

• Voltage level translation between different logic families
• Bidirectional data buses in embedded systems
• Industrial control interfaces requiring mixed voltage nodes

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix PWR indicates the TSSOP-24 tape-and-reel packaging configuration. Confirm that the AXC series designation aligns with the required performance specifications for your design. Ensure compatibility with existing board layouts and thermal management requirements before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing devices operating at distinct voltage levels within the 0.65 V to 3.6 V range. The AXC series offers higher speed capabilities compared to standard AVC counterparts. Consider the TSSOP-24 package dimensions for PCB footprint constraints and verify that the required data rate does not exceed the limits defined by the applied supply voltages.
