AD8074ARU

Overview

The AD8074ARU is a high-speed triple video buffer from Analog Devices, housed in a 16-lead TSSOP package. It operates on dual supplies ranging from ±4.5 V to ±5.5 V with quiescent current under 30 mA. The device features a small-signal bandwidth of 600 MHz and a slew rate of 1600 V/µs at unity gain. It provides excellent video specifications including 0.01% differential gain error and 90 dB off-isolation. A fast output disable feature allows outputs to enter a high-impedance state for multiplexing applications.

Feature Summary

• Triple-channel architecture optimized for buffering RGB video sources with low differential gain and phase error.
• High-speed fully buffered inputs and outputs ensuring signal integrity across wide frequency ranges.
• Fast output disable function enables high-impedance states for building larger input arrays while minimizing channel loading.

Applications

• RGB Buffer in LCD and Plasma Displays
• RGB Driver circuits
• Video Routers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging options such as tube or reel configurations. Ensure the selected variant matches the required temperature range and RoHS compliance status for your specific design implementation.

Selection Notes

Select the AD8074ARU for designs requiring unity gain buffering with high bandwidth. Consider the AD8075 variant if a fixed gain of +2 is necessary for driving secondary monitors or specific termination schemes. Evaluate power supply constraints and PCB layout requirements for high-speed signal routing.

Part Context

This component belongs to the AD8074/AD8075 family of high-speed video buffers designed by Analog Devices. These devices are engineered for demanding video applications where maintaining signal fidelity and minimizing distortion are critical. The family offers both unity gain and gain-of-two configurations within the same pinout-compatible package structure.

Replacement Considerations

Public confirmed substitute part numbers: AD8074ARUZ, AD8074ARUZ-REEL, AD8074ARUZ-REEL7.

FAQ

How does the output disable feature function?

The OE (Output Enable) pin controls the state of all three outputs. When OE is logic high, the outputs enter a high-impedance state, reducing power consumption and allowing multiple devices to be bus-connected without interference.

What is the maximum operating supply voltage?

The absolute maximum supply voltage is 12.0 V. The recommended operating range is typically ±4.5 V to ±5.5 V.
