SN74AVC16T245GKER

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC16T245GKER is a 16-bit dual-supply bus transceiver with configurable voltage-level shifting and tri-state outputs. It supports VCCA and VCCB supply voltages ranging from 1.2V to 3.6V, enabling universal bidirectional translation between any low-voltage nodes including 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. The device features overvoltage-tolerant I/Os rated up to 4.6V, ensuring safe mixed-voltage communication. It includes VCC isolation functionality that forces both ports into a high-impedance state if either supply rail drops to ground.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Fully configurable dual-rail design allows independent operation of each port across the full 1.2V to 3.6V power-supply range.
• Ioff circuitry supports partial-power-down mode by disabling outputs to prevent damaging current backflow during power loss.
• VCC isolation feature ensures both ports enter a high-impedance state if either VCCA or VCCB input is at GND.
• Overvoltage-tolerant inputs and outputs support mixed-voltage-mode data communications with 4.6V tolerance.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'GKER' corresponds to the BGA Microstar Junior package as indicated in the datasheet's orderable addendum. Confirm the manufacturer is Texas Instruments and check for RoHS compliance status. Ensure the component matches the SCES551F document revision. Validate that the ordering suffix does not alter the electrical function unless explicitly stated in official documentation.

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 applications needing independent direction control for data flow. Consider the thermal characteristics of the BGA Microstar Junior package for PCB layout. Ensure unused inputs are tied to ground or VCCI to prevent excessive leakage.
