SN74AVC4T245DT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC4T245DT is a 4-bit dual-supply bus transceiver with configurable voltage translation and 3-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 1.2V to 3.6V for both VCCA and VCCB ports. The device supports asynchronous communication between two data buses with a maximum data rate of 380Mbps when translating from 1.8V to 3.3V. It features I/Os that are 4.6V tolerant and includes an Ioff circuit for partial power-down mode operation. The component is housed in a 16-pin SOIC-Narrow package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Fully configurable dual-rail design allows each port to operate over the full 1.2V to 3.6V power-supply range
• I/Os are 4.6V tolerant providing flexibility for interfacing different voltage nodes
• Ioff supports partial power-down mode operation preventing damaging current backflow
• Control inputs VIH/VIL levels are referenced to VCCA voltage

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DT' corresponds to the SOIC-16 package configuration as documented in the manufacturer's datasheet. Confirm that the component meets RoHS compliance requirements for your target market. Ensure that the supply chain source provides valid traceability documentation consistent with Texas Instruments production standards.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when bidirectional level translation is required between logic families operating at different voltages within the 1.2V to 3.6V range. The device is suitable for designs requiring high-speed data transfer up to 380Mbps. Consider the 16-pin SOIC package dimensions for PCB layout constraints. Verify that the control input referencing to VCCA aligns with the system's power sequencing strategy.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AVC4T245 family of low-voltage bus transceivers. The family shares identical electrical characteristics and functional descriptions but differs in physical packaging options such as TVSOP, TSSOP, WQFN, UQFN, and SOT. The 'DT' suffix specifically identifies the Narrow SOIC package variant among these available form factors.
