SN74AVC16T245DGVR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC16T245DGVR is a 16-bit dual-supply noninverting bus transceiver with configurable voltage-level shifting and tri-state outputs. It operates with VCCA and VCCB ranging from 1.2V to 3.6V, supporting universal bidirectional translation between 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V nodes. The device features overvoltage-tolerant I/Os up to 4.6V, Ioff support for partial-power-down modes, and VCC isolation to prevent false logic levels when power rails are grounded.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable dual-rail design allows independent operation of ports across the full 1.2V to 3.6V supply range.
• Ioff circuitry disables outputs to prevent damaging current backflow during partial-power-down conditions.
• VCC isolation feature ensures both ports enter a high-impedance state if either supply input is at ground potential.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package suffix 'DGVR' corresponds to the TVSOP-48 form factor and reel packaging configuration required for your assembly line. Confirm that the component meets RoHS compliance standards and check for any recent Product Change Notifications (PCN) regarding material or manufacturing site updates before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing mixed-voltage buses requiring asynchronous communication between distinct power domains. Ensure the application utilizes separate VCCA and VCCB supplies within the 1.2V to 3.6V range. Verify that the DIR and OE control signals are referenced correctly to VCCA to manage data direction and output enable states effectively.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AVC16T245 family of 16-bit dual-supply bus transceivers. The 'DGVR' suffix indicates a TVSOP-48 package with reel packaging. It is designed for low-voltage portable applications where flexible voltage translation between multiple standard logic levels is necessary without external level-shifting components.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74AVC16T245DGG is a pin-compatible alternative in a TSSOP-48 package. SN74AVC16T245GQL is available in a BGA Microstar Junior package. Verify thermal resistance and physical footprint differences when substituting these variants.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the VCC isolation feature function?

If either VCCA or VCCB input is at GND, both ports automatically enter a high-impedance state to prevent false logic levels on the buses.

What is the purpose of the Ioff circuitry?

The Ioff circuitry supports partial-power-down mode by disabling the outputs, which prevents damaging current backflow through the device when it is powered down.
