SN74AVC16244GQLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC16244GQLR 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 optimized for 1.65 V to 3.6 V applications. The device features overvoltage-tolerant inputs and outputs, enabling mixed-voltage-mode data communications without external level shifters. It incorporates Dynamic Output Control (DOC) circuitry to dynamically adjust output impedance, reducing noise during signal transitions while maintaining high drive capability equivalent to standard outputs at ±24 mA. The component supports partial-power-down mode via Ioff circuitry to prevent damaging backflow currents.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Overvoltage-tolerant inputs and outputs facilitate direct communication between systems operating at different voltage levels.
• Dynamic Output Control (DOC) circuitry adjusts output impedance during transitions to minimize electromagnetic interference and noise.
• Ioff circuitry enables partial-power-down mode operation by disabling outputs to prevent current backflow when the device is unpowered.
• ESD protection ratings exceed JESD 22 standards, ensuring robustness against human-body and machine-model electrostatic discharge events.
