Replacement verdict
Compatible functional replacement candidate
The AD8184AR and AD8180ARZ-R7 are both high-speed analog multiplexers from Analog Devices sharing the same SOIC-14 footprint and ±5 V supply architecture, making the AD8180ARZ-R7 a viable functional replacement candidate for the AD8184AR in many switching applications. Designers should confirm channel configuration and bandwidth headroom against their specific signal-path requirements before committing to the substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AD8184AR | AD8180ARZ-R7 | Why it matters |
|---|---|---|---|
| Function / Configuration | 4:1 analog multiplexer (video mux) | 2:1 analog multiplexer (video mux) | The channel count determines how many inputs can be routed to a single output, so a 4:1 and 2:1 part are not directly substitutable in a signal-routing design. |
| Number of Channels (Inputs) | 4 inputs to 1 output | 2 inputs to 1 output | The number of switchable inputs defines the multiplexing capability and the board-level routing architecture. |
| -3 dB Bandwidth | 700 MHz | 750 MHz | Bandwidth sets the maximum signal frequency the mux can pass with acceptable attenuation, critical for video and high-speed signal chains. |
| Slew Rate | 750 V/µs | 500 V/µs | Slew rate affects large-signal transient response and settling, influencing distortion and pulse fidelity in fast switching applications. |
| Supply Voltage Range | ±5 V (dual supply) | ±5 V (dual supply) | Supply requirements must match the system rails; both parts operate on ±5 V, so power-supply compatibility is maintained. |
| Package | 14-lead SOIC | 8-lead SOIC | Package footprint and pin count affect PCB layout and drop-in compatibility; different packages require board redesign. |
| Channel-to-Channel Switching Time | ~25 ns | ~20 ns | Switching time determines how quickly the mux can change channels, which matters for time-multiplexed and fast-scanning systems. |
| On Resistance | ~10 Ω | ~10 Ω | On resistance affects signal attenuation and loading; similar values indicate comparable signal integrity when driving downstream stages. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | The temperature range must cover the application environment; matching ranges confirm equivalent environmental robustness. |

Frequently asked questions
What are the primary functional differences between the AD8184AR and AD8180ARZ-R7?
The AD8184AR is a 4:1 analog multiplexer, while the AD8180ARZ-R7 is a 2:1 analog multiplexer. Both are high-speed, low-power devices from Analog Devices, but they differ in channel count and package options. The AD8184AR is supplied in a 14-lead SOIC package, whereas the AD8180ARZ-R7 is supplied in an 8-lead SOIC package and is provided in tape-and-reel format (R7 suffix).
Are the AD8184AR and AD8180ARZ-R7 pin-compatible?
No. The AD8184AR uses a 14-lead SOIC package, and the AD8180ARZ-R7 uses an 8-lead SOIC package. The pin counts and pin functions differ, so they are not drop-in replacements for each other on the same PCB footprint.
What are the key AC specifications of these multiplexers?
Both the AD8184 and AD8180 are high-speed analog multiplexers with a -3 dB bandwidth of 700 MHz (typical) and a slew rate of 750 V/µs. These specifications are common to the AD8180/AD8184 family as documented in the Analog Devices datasheet.
What supply voltage and power consumption do the AD8184AR and AD8180ARZ-R7 require?
Both devices operate from dual ±5 V supplies (or a single +5 V supply in some configurations) and typically consume approximately 4.5 mA of supply current per device, making them suitable for low-power video and signal-routing applications.
What is the difference between the "AR" and "ARZ-R7" suffixes?
The "AR" suffix on the AD8184AR denotes a 14-lead SOIC package in tube form. The "ARZ-R7" suffix on the AD8180ARZ-R7 denotes an 8-lead SOIC package (Z indicates RoHS-compliant) supplied in tape-and-reel packaging with a 7-inch reel. The Z suffix confirms RoHS compliance for the AD8180ARZ-R7.
Can the AD8180ARZ-R7 be used to replace the AD8184AR in an existing 4:1 multiplexer design?
No. The AD8180ARZ-R7 is a 2:1 multiplexer and cannot provide the four input channels required by a 4:1 multiplexer design. A functional replacement for the AD8184AR would require a 4:1 multiplexer with a compatible 14-lead SOIC pinout, not the 2:1 AD8180ARZ-R7.
What are the typical applications for the AD8184AR and AD8180ARZ-R7?
Both devices are intended for high-speed signal routing in video, imaging, and communication systems. The AD8184AR (4:1) is suited to selecting among four video or signal sources, while the AD8180ARZ-R7 (2:1) is suited to two-source selection, such as RGB or composite video switching in compact 8-lead layouts.
