AD8074ARU-REEL7

Overview

The AD8074ARU-REEL7 is a high-speed triple video buffer with unity gain (G = +1), housed in a 16-lead TSSOP package. It operates on dual supplies ranging from ±4.5 V to ±5.5 V, consuming less than 30 mA when active. The device features a –3 dB bandwidth of up to 600 MHz for small signals and 500 MHz for large signals. Slew rates reach 1600 V/µs at G = +1. It includes a fast output disable feature that isolates outputs to a high-impedance state.

Feature Summary

• Triple-channel architecture providing independent buffering for RGB video signals
• High-speed fully buffered inputs and outputs optimized for video applications
• Fast output disable function allowing high-impedance isolation for matrix switching
• Low differential gain and phase error suitable for NTSC or PAL composite signals

Applications

• RGB buffering for LCD and plasma displays
• Video routers and multiplexers
• Driving second monitors via gain-of-two configurations

Procurement Notes

Verify the specific ordering suffix RU-16 corresponds to the 16-lead Thin Shrink Small Outline Package. Confirm RoHS compliance status if required by your assembly process. Ensure supply voltages remain within the specified ±4.5 V to ±5.5 V range during operation. Check datasheet for absolute maximum ratings regarding power dissipation and thermal derating curves.

Selection Notes

Select this component for applications requiring high bandwidth and low distortion in video signal paths. The AD8074 provides unity gain, whereas the AD8075 offers gain of two; choose based on termination requirements. Consider the fast settling time and high slew rate for high-resolution graphics. Evaluate PCB layout needs for ground planes and bypassing to maintain performance.
