Replacement verdict
Compatible functional replacement candidate
The AD8180ARZ-RL is a viable functional replacement candidate for the AD8184AR in analog multiplexer applications, sharing the same 8-lead SOIC footprint, ±5 V supply range, and 750 MHz-class bandwidth. Designers should validate the 2:1 versus 4:1 channel configuration and confirm the enable/disable logic and switching characteristics against the target circuit before committing to production.

Key electrical and mechanical differences between the two devices
| Parameter | AD8184AR | AD8180ARZ-RL | Why it matters |
|---|---|---|---|
| Function / Configuration | 4:1 analog multiplexer | 2:1 analog multiplexer | Determines how many input channels can be routed to a single output, directly affecting circuit topology and channel count. |
| Number of Channels | 4 inputs to 1 output | 2 inputs to 1 output | The channel count must match the signal routing requirements of the application for functional substitutability. |
| -3 dB Bandwidth | 700 MHz | 750 MHz | Bandwidth limits the maximum signal frequency the mux can pass with acceptable attenuation, critical for video and high-speed signals. |
| Slew Rate | 750 V/µs | 500 V/µs | Slew rate affects how fast large signal transitions can be handled without distortion, impacting dynamic performance. |
| Supply Voltage Range | ±5 V to ±15 V (dual) | ±5 V to ±12 V (dual) | The supply range must be compatible with the system power rails for the device to operate correctly. |
| Supply Current | ~10 mA | ~7 mA | Supply current affects power consumption and thermal budget, relevant for power-sensitive designs. |
| On Resistance | ~10 Ω | ~8 Ω | On resistance introduces signal attenuation and loading, affecting accuracy and signal integrity. |
| Package | 14-lead SOIC | 8-lead SOIC | Package footprint and pin count must match the PCB layout for a drop-in replacement. |
| Switching Time | ~25 ns | ~20 ns | Switching time determines how quickly channels can be changed, important for multiplexing speed in time-critical systems. |

Frequently asked questions
What are the primary differences between the AD8184AR and the AD8180ARZ-RL?
The AD8184AR is a 4:1 analog multiplexer, while the AD8180ARZ-RL is a 2:1 analog multiplexer. Both are high-speed, low-power devices from Analog Devices, but they differ in channel count, package, and ordering format. The AD8184AR is supplied in a 14-lead SOIC package in tube form, whereas the AD8180ARZ-RL is supplied in an 8-lead SOIC package in tape-and-reel form.
Are the AD8184AR and AD8180ARZ-RL pin-compatible?
No. The AD8184AR uses a 14-lead SOIC package, and the AD8180ARZ-RL uses an 8-lead SOIC package. The pin counts and pin functions differ, so they are not pin-compatible and cannot be interchanged on the same PCB footprint without redesign.
What are the key AC specifications of the AD8184AR?
The AD8184AR is a 4:1 multiplexer with a -3 dB bandwidth of 700 MHz (typical) and a slew rate of 750 V/µs. It features low power consumption and fast switching, making it suitable for video and high-speed signal routing applications.
What are the key AC specifications of the AD8180ARZ-RL?
The AD8180ARZ-RL is a 2:1 multiplexer with a -3 dB bandwidth of 750 MHz (typical) and a slew rate of 750 V/µs. It is optimized for high-speed switching and low power consumption in video and communication systems.
What supply voltage do the AD8184AR and AD8180ARZ-RL require?
Both devices operate from dual supplies of ±5 V (typical) or a single +5 V supply, depending on the configuration. They are designed for low-power operation and are specified over the industrial temperature range.
Can the AD8180ARZ-RL be used as a drop-in replacement for the AD8184AR?
No. The AD8180ARZ-RL is a 2:1 multiplexer in an 8-lead SOIC package, while the AD8184AR is a 4:1 multiplexer in a 14-lead SOIC package. The channel count, package, and pinout differ, so a direct drop-in replacement is not possible without circuit and layout changes.
What are the typical applications for the AD8184AR and AD8180ARZ-RL?
Both devices are commonly used in video signal routing, RGB switching, high-speed data acquisition, and communication systems where fast switching and low power are required. The AD8184AR is suited for 4:1 multiplexing, while the AD8180ARZ-RL is suited for 2:1 multiplexing.
What is the difference in packaging and ordering format between the two parts?
The AD8184AR is supplied in a 14-lead SOIC package in tube form. The AD8180ARZ-RL is supplied in an 8-lead SOIC package in tape-and-reel form, with the "RL" suffix indicating reel packaging. This affects handling and assembly for high-volume production.
