SN74AVC16T245DGG

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC16T245DGG is a 16-bit dual-supply bus transceiver with configurable voltage-level shifting and tri-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 1.2 V to 3.6 V for both VCCA and VCCB rails. The device supports asynchronous bidirectional data transmission between buses based on the DIR input logic level. It features overvoltage-tolerant I/Os up to 4.6 V, enabling mixed-voltage communication. The component is housed in a 48-pin TSSOP package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable dual-rail design allows independent power supply settings for each port across the full 1.2 V to 3.6 V range.
• VCC isolation feature ensures high-impedance state for both ports if either supply rail is at ground potential.
• Ioff circuitry supports partial-power-down mode by disabling outputs to prevent damaging current backflow.
• Overvoltage-tolerant inputs and outputs facilitate safe mixed-voltage-mode data communications.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DGG' corresponds to the 48-pin TSSOP package configuration. Confirm that the required operating temperature range aligns with the specified -40°C to +85°C limits. Ensure compatibility with the intended voltage levels for VCCA and VCCB before integration into the final system design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing data buses requiring asynchronous bidirectional translation between different low-voltage nodes. It is suitable for applications needing configurable power supplies for separate A and B ports. Consider its ESD protection ratings and latch-up performance for robust operation in sensitive environments.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74AVC16T245 family of 16-bit dual-supply bus transceivers. It shares functional characteristics with other variants in the series but differs in packaging options such as TVSOP or BGA Microstar Junior. The DGG suffix specifically denotes the TSSOP physical form factor used in this instance.

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.

What is the purpose of the Ioff circuitry?

It disables the outputs during partial-power-down mode to prevent damaging current backflow through the device.
