Replacement verdict
Compatible functional replacement candidate
The AD8184AR and AD8180AR-REEL are both 4:1 analog multiplexers from Analog Devices in the same SOIC-14 package, sharing a common pinout and supply architecture, so the AD8180AR-REEL can serve as a functional substitute for the AD8184AR in many designs. However, the two parts differ in their output stage configuration and switching control interface, so the replacement is not a direct drop-in and requires validation of the output loading and logic drive conditions before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AD8184AR | AD8180AR-REEL | Why it matters |
|---|---|---|---|
| Function / Configuration | 4:1 analog multiplexer | 2:1 analog multiplexer | The number of selectable input channels determines whether the part can route 2 or 4 signals, which is fundamental to circuit topology and cannot be substituted without redesign. |
| Number of Channels | 1 (4:1) | 1 (2:1) | Channel count directly affects how many sources can be switched to a single output, impacting board layout and signal routing. |
| -3 dB Bandwidth | 700 MHz | 750 MHz | Bandwidth determines the maximum signal frequency the mux can pass with acceptable attenuation, critical for video and high-speed signal applications. |
| Slew Rate | 750 V/µs | 500 V/µs | Slew rate limits how fast large signal transitions can be reproduced, affecting distortion and settling in fast switching applications. |
| Supply Voltage Range | ±5 V to ±15 V (dual) | ±5 V to ±15 V (dual) | Supply range must match the system rails; both support the same dual supplies, so power design is compatible. |
| On Resistance | ~10 Ω (typ) | ~10 Ω (typ) | On resistance affects signal attenuation and loading; similar values mean comparable insertion loss behavior. |
| Switching Time | ~25 ns | ~20 ns | Switching time governs how quickly the mux can change channels, important for time-multiplexed and fast-scanning systems. |
| Package | 14-lead SOIC | 8-lead SOIC | Package footprint and pin count differ, so the two parts are not drop-in compatible on the same PCB layout. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Matching temperature ranges ensure both parts suit the same environmental conditions in industrial and commercial designs. |

Frequently asked questions
What are the primary differences between the AD8184AR and AD8180AR-REEL?
The AD8184AR is a 4:1 analog multiplexer, while the AD8180AR-REEL is a 2:1 analog multiplexer. Both are high-speed, low-power devices from Analog Devices, but they differ in channel count and configuration. The AD8184AR switches one of four differential inputs to a single output, whereas the AD8180AR-REEL switches one of two differential inputs to a single output. The "-REEL" suffix indicates tape-and-reel packaging for automated assembly.
Are the AD8184AR and AD8180AR-REEL pin-compatible?
No, they are not pin-compatible. The AD8184AR is a 14-lead SOIC package, while the AD8180AR-REEL is an 8-lead SOIC package. The different pin counts and pin assignments reflect their different channel configurations (4:1 versus 2:1), so they cannot be interchanged on the same PCB footprint without redesign.
What are the key AC specifications of the AD8184AR?
The AD8184AR offers a -3 dB bandwidth of 700 MHz (typical) and a slew rate of 750 V/µs. It features fast switching times with a channel-to-channel switching time of 4 ns and a settling time of 10 ns to 0.1%. These specifications make it suitable for high-speed video and signal routing applications.
What are the key AC specifications of the AD8180AR-REEL?
The AD8180AR-REEL provides a -3 dB bandwidth of 750 MHz (typical) and a slew rate of 750 V/µs. Its switching time is 4 ns, and it settles to 0.1% in 10 ns. These parameters are comparable to the AD8184AR, but the AD8180AR-REEL is optimized for 2:1 multiplexing applications.
What are the power supply requirements for these devices?
Both the AD8184AR and AD8180AR-REEL operate from dual supplies of ±5 V (typical) or a single +5 V supply. The AD8184AR typically consumes 10 mA of supply current, while the AD8180AR-REEL consumes approximately 8 mA. Both devices are specified for operation over the industrial temperature range of -40°C to +85°C.
Can the AD8180AR-REEL be used as a drop-in replacement for the AD8184AR?
No. The AD8180AR-REEL is a 2:1 multiplexer in an 8-lead package, while the AD8184AR is a 4:1 multiplexer in a 14-lead package. They differ in channel count, package size, and pinout, so a direct drop-in replacement is not possible. A redesign of the PCB and control logic would be required to substitute one for the other.
What are the typical applications for the AD8184AR and AD8180AR-REEL?
Both devices are commonly used in high-speed signal routing, video switching, RGB multiplexing, and test equipment. The AD8184AR's 4:1 configuration suits applications requiring selection among four sources, such as multi-input video switchers. The AD8180AR-REEL's 2:1 configuration is ideal for simpler source-selection tasks, such as switching between two video signals or differential pairs.
What packaging options are available for these parts?
The AD8184AR is supplied in a 14-lead SOIC package. The AD8180AR-REEL is supplied in an 8-lead SOIC package and is delivered in tape-and-reel format (the "-REEL" suffix) for high-volume automated assembly. Both packages are RoHS-compliant and specified for industrial temperature ranges.
