SN74AVC16646D

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC16646D is a 16-bit registered bus transceiver manufactured by Texas Instruments. It operates with dual power supplies, supporting VCCA from 1.08V to 3.6V and VCCB from 1.08V to 3.6V. The device features 3-state outputs and supports data rates up to 380Mb/s. It includes an output enable pin and direction control for bidirectional data transfer between buses of different voltage levels. The component is housed in a 56-pin TSSOP package and is designed for low-voltage applications requiring level translation.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports bidirectional data transfer between buses operating at different voltage levels

• Voltage translation in industrial control systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the exact suffix 'D' corresponds to the TSSOP-56 package variant when ordering. Confirm that the required voltage levels for both VCCA and VCCB fall within the specified 1.08V to 3.6V range for your specific application design. Ensure compatibility with the 380Mb/s data rate requirement if used in high-speed signaling environments.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when dual-supply level translation is required for 16-bit wide buses. It is suitable for applications needing registered data transfer with low power consumption. Compare against non-registered variants if latching functionality is not needed. Consider package availability and thermal performance for dense PCB layouts.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AVC16646 family of registered bus transceivers. It is part of Texas Instruments' AVC series, which focuses on low-voltage, high-speed level shifting solutions. The family offers various pin counts and package options to suit different bandwidth and interface requirements in modern electronic systems.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74AVC16646DGGR as a tape-and-reel alternative in the same family. Verify pinout compatibility before substituting with other 16-bit level shifters. Ensure the replacement supports the same dual-supply voltage ranges and data rate specifications.
