SN74AVC16244DGGR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC16244DGGR is a 16-bit buffer and driver with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 1.4 V to 3.6 V, specifically designed for 1.65 V to 3.6 V applications. The device features overvoltage-tolerant inputs and outputs, supporting mixed-voltage-mode data communications. It includes an Ioff circuit that supports partial-power-down mode operation to prevent damaging current backflow. The package is a 48-pin TSSOP (DGG) with a tape and reel configuration.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the DOC circuit benefit signal integrity?

The DOC circuit dynamically lowers output impedance during transitions to drive loads effectively, then raises it to reduce noise, maintaining speed while improving signal quality.

What is the purpose of the Ioff circuit?

The Ioff circuit disables outputs when the device is powered down, preventing damaging current backflow through the device in partial-power-down applications.
