SN74AVC16T245DGGR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC16T245DGGR is a 16-bit dual-supply bus transceiver with configurable voltage-level shifting and tri-state outputs. It operates with VCCA and VCCB ranging from 1.2V to 3.6V, enabling bidirectional translation between any low-voltage nodes including 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. The device supports maximum data rates up to 380Mbps when level-shifting between 1.8V and 3.3V. It features overvoltage-tolerant I/Os rated at 4.6V, ensuring compatibility in mixed-voltage applications.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable dual-rail design allows independent operation of ports across the full 1.2V to 3.6V power-supply range for universal low-voltage translation.
• Ioff circuitry supports partial-power-down mode by disabling outputs to prevent damaging backflow current during power-off states.
• VCC isolation feature ensures both ports enter a high-impedance state if either supply input is grounded, preventing false logic levels.

• Personal electronics
• Industrial systems
• Enterprise infrastructure
• Telecommunications equipment

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the DGGR suffix indicates a reel package configuration upon ordering. Confirm that the specific revision level matches the design requirements. Ensure ESD protection measures are adequate for the manufacturing environment given the component's sensitivity ratings. Validate that the TSSOP-48 footprint aligns with the PCB layout specifications before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing buses requiring asynchronous communication between different voltage domains within the 1.2V to 3.6V range. It is suitable for designs needing high-speed data transfer up to 380Mbps. Consider the VCC isolation and Ioff features if the system requires safe partial-power-down capabilities or protection against ground faults on supply rails.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74AVC16T245 series of 16-bit bus transceivers manufactured by Texas Instruments. It is part of the AVC logic family designed for advanced low-voltage applications. The DGGR variant specifically denotes the TSSOP-48 package type with reel packaging, distinguishing it from tube-packaged versions like the DGG suffix.
