Replacement verdict
Compatible functional replacement candidate
The ADG609BRUZ and ADG609BRU are functionally equivalent CMOS analog multiplexers sharing identical channel count, switch configuration, on-resistance, and supply requirements; the only distinction is the package finish (RoHS-compliant versus non-compliant), making the BRUZ a direct functional substitute where lead-free compliance is required.

Key electrical and mechanical differences between the two devices
| Parameter | ADG609BRUZ | ADG609BRU | Why it matters |
|---|---|---|---|
| Number of Channels | 2 (dual 4:1) | 2 (dual 4:1) | Defines the multiplexer configuration; both are dual 4-to-1 multiplexers, so channel count and switching topology are functionally equivalent. |
| On-Resistance (RON) | ~30 Ω (typ) | ~30 Ω (typ) | On-resistance affects signal attenuation and voltage drop across the switch; matching values ensure equivalent signal integrity in the target circuit. |
| Supply Voltage Range | ±5 V dual or +5 V single | ±5 V dual or +5 V single | Determines compatibility with the system power rails; identical ranges mean the parts are interchangeable without supply redesign. |
| Package / Mounting | 16-TSSOP (surface mount) | 16-TSSOP (surface mount) | Package and footprint must match for drop-in replacement on an existing PCB; both use the same 16-lead TSSOP. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Confirms the part meets the environmental requirements of the application; identical ranges ensure equivalent thermal performance. |
| RoHS / Lead-Free Status | RoHS compliant, lead-free | Non-RoHS (contains lead) | The "Z" suffix denotes lead-free/RoHS compliance; this is the key differentiator affecting regulatory compliance and solder process compatibility. |
| Switching Time (tON/tOFF) | ~65 ns / ~40 ns (typ) | ~65 ns / ~40 ns (typ) | Switching speed impacts timing in multiplexed signal paths; matching values ensure identical dynamic behavior. |
| Leakage Current (Off) | ~0.1 nA (typ) | ~0.1 nA (typ) | Low off-leakage preserves accuracy in high-impedance signal chains; equivalent leakage means equivalent precision performance. |

Frequently asked questions
What is the difference between ADG609BRUZ and ADG609BRU?
The ADG609BRUZ is the RoHS-compliant, lead-free (Pb-free) version of the ADG609BRU. Both are dual 4-channel analog multiplexers in a 16-lead TSSOP package with identical electrical specifications; the suffix "Z" denotes the RoHS-compliant packaging option per Analog Devices part numbering conventions.
Are ADG609BRUZ and ADG609BRU electrically and functionally interchangeable?
Yes. Both devices share the same dual 4:1 multiplexer architecture, on-resistance, supply range, and pinout. The only documented difference is the RoHS/lead-free compliance status indicated by the "Z" suffix, so they are functionally equivalent in circuit design.
What are the key specifications of the ADG609 multiplexer?
The ADG609 is a dual 4-channel (4:1) analog multiplexer with on-resistance typically around 60 Ω, operating from dual ±5 V or single +5 V supplies, featuring low power consumption, TTL/CMOS-compatible logic inputs, and fast switching times, housed in a 16-lead TSSOP package.
Does the "Z" suffix affect the package or pinout?
No. Both ADG609BRUZ and ADG609BRU use the same 16-lead TSSOP (RU) package with identical pin assignments. The "Z" designation refers only to RoHS compliance and does not alter package dimensions or pin functions.
Which version should be selected for new designs requiring RoHS compliance?
The ADG609BRUZ should be selected for new designs, as it is the RoHS-compliant, lead-free variant. The ADG609BRU (non-Z) is the legacy non-RoHS version and may not satisfy current environmental compliance requirements.
Can ADG609BRU be used as a drop-in replacement for ADG609BRUZ?
Electrically and functionally yes, since both share identical specifications and pinout. However, substituting the non-RoHS ADG609BRU into a design specified with the RoHS-compliant ADG609BRUZ may violate the product's environmental compliance documentation, so the substitution should be validated against the target design's compliance requirements.
