Product details
Overview
AD8074ARU-REEL7 from Analog Devices is a triple-channel, unity-gain (+1) high-speed video buffer IC optimized for RGB signal conditioning in display interfaces. It delivers 500 MHz large-signal bandwidth (2 Vp-p, RL = 150 Ω), 1600 V/µs slew rate, 4 ns settling time to 0.1%, <30 mA quiescent current, and 0.01% differential gain error - enabling precise analog video buffering in LCD/plasma displays and video routers.
For engineers reviewing the AD8074ARU-REEL7 datasheet, AD8074ARU-REEL7 pinout, AD8074ARU-REEL7 application, or AD8074ARU-REEL7 equivalent, key selection criteria include its G = +1 fixed gain architecture, TSSOP-16 package with OE-controlled high-Z disable, all-hostile crosstalk ≤ –80 dB at 10 MHz, and ±4.5 V to ±5.5 V dual-supply operation with rail-to-rail output swing capability.
Technical Context
The AD8074ARU-REEL7 implements three independent fully buffered channels, each with NPN transconductance input stages and emitter-follower output buffers. Its internal voltage feedback network configures it as a unity-gain follower, distinct from the AD8075's G = +2 architecture with isolated feedback termination.
It features TTL-compatible OE control enabling simultaneous high-impedance disable of all three outputs, reducing off-channel loading in multiplexed or bus-shared video architectures. The device maintains >–80 dB all-hostile crosstalk up to 10 MHz and 90 dB OFF isolation at 10 MHz, achieved via careful die layout and AGND/DGND separation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-Signal BW (–3 dB) | 600 MHz @ 200 mVp-p, 5 pF load - supports ultra-high-resolution pixel clock harmonics without attenuation. |
| Large-Signal BW (–3 dB) | 500 MHz @ 2 Vp-p, 150 Ω load - preserves full amplitude integrity for broadcast-level video signals. |
| Slew Rate | 1600 V/µs - enables clean 2 V step response with <4 ns settling, critical for fast video transitions. |
| Differential Gain/Phase Error | 0.01% / 0.01° @ 3.58 MHz - meets NTSC/PAL composite video fidelity requirements. |
| All-Hostile Crosstalk | –80 dB @ 10 MHz - prevents visible color bleed between RGB channels in high-density routing. |
| OFF Isolation | 90 dB @ 10 MHz - ensures minimal signal leakage when disabled, essential for video multiplexer applications. |
| Supply Current | 21.5–30 mA (all ON), 3–5.5 mA (all OFF) - enables low-power standby modes in multi-buffer systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple video buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8075ARUZ-REEL7 | G = +2 fixed gain; higher 1350 V/µs slew rate; different feedback network topology. | Used where signal amplitude halving occurs (e.g., series-terminated 75 Ω video lines), requiring gain compensation. | Select AD8075ARUZ-REEL7 only when system-level signal loss mandates +2 gain; AD8074ARU-REEL7 is preferred for direct buffering without amplification. |
| THS3201DGNR | Single-channel, 1.8 GHz BW, 6000 V/µs slew rate; no integrated OE; SOIC-8 package. | Requires three discrete devices and external logic for tri-state control; higher power (12 mA/channel). | Choose THS3201DGNR only for non-standard gain, bandwidth beyond 500 MHz, or legacy SOIC footprint compatibility. |
Compared with AD8075ARUZ-REEL7, AD8074ARU-REEL7 provides lower noise (19.5 nV/√Hz vs. 22 nV/√Hz) and tighter DC specs (±0.15% gain error vs. ±0.65%), while THS3201DGNR offers higher bandwidth but lacks integrated disable and triple-channel integration - increasing BOM count and layout complexity.

FAQ
What is the operating supply voltage range for the AD8074ARU-REEL7?
The AD8074ARU-REEL7 operates from dual supplies of ±4.5 V to ±5.5 V. It supports single-supply operation at 10 V with AGND tied near midsupply, though dual ±5 V is the specified condition for all published AC/DC performance metrics. The absolute maximum supply rating is ±12 V, but operation outside ±5.5 V risks parametric degradation.
Does the AD8074ARU-REEL7 support DC-coupled video signal paths?
Yes, the AD8074ARU-REEL7 supports DC-coupled operation with input voltage range of ±2.8 V (relative to AGND) and output swing extending to within 2.3 V of either rail under 150 Ω load. This enables accurate transmission of sync pulses and black-level references without AC coupling capacitors in RGB systems.
How does the OE pin function on the AD8074ARU-REEL7?
The OE pin on the AD8074ARU-REEL7 is an active-low TTL-compatible enable input. When OE is logic LOW (≤0.8 V), all three outputs drive their respective inputs. When OE is logic HIGH (≥2.0 V), all outputs enter high-impedance state with >3.5 MΩ disabled output resistance, reducing total supply current to 3–5.5 mA.
What is the recommended PCB layout practice for minimizing crosstalk in AD8074ARU-REEL7 designs?
To minimize crosstalk, the AD8074ARU-REEL7 requires strict separation of AGND and DGND planes, full ground plane coverage beneath the device, individual 0.1 µF ceramic bypass caps at each VCC/VEE pin with minimal trace length, and controlled-impedance routing for all video traces. Layout Figure 5 in the datasheet shows validated implementation with 75 Ω impedance lines and AGND shielding between channels.
Can the AD8074ARU-REEL7 drive 75 Ω coaxial cables directly?
Yes - the AD8074ARU-REEL7 is optimized for 75 Ω video loads. Its low output impedance (<0.5 Ω enabled) allows direct series termination with 75 Ω resistors at the output, matching standard video line impedance and eliminating reflections. Internal gain flatness and phase response are characterized into 150 Ω (dual-terminated) and 1 kΩ loads per datasheet Table I.
