Key electrical and mechanical differences between the two devices
| Parameter | ADG739BRUZ | ADG739BRU | Why it matters |
|---|---|---|---|
| Number of Channels | 2 (dual SPDT) | 2 (dual SPDT) | Defines how many independent signal paths can be switched; must match for functional substitutability. |
| Switch Configuration | SPDT (2:1 mux) | SPDT (2:1 mux) | Determines the routing topology; identical configuration ensures drop-in replacement in the circuit. |
| On-Resistance (RDS(on)) | 4 Ω (typ) | 4 Ω (typ) | Affects signal attenuation and voltage drop; matching values preserve signal integrity. |
| Supply Voltage Range | 1.8 V to 5.5 V (single supply) | 1.8 V to 5.5 V (single supply) | Must be compatible with the system power rail for correct operation. |
| Package / Mounting | 16-TSSOP (surface mount) | 16-TSSOP (surface mount) | Footprint and mounting style must match for PCB compatibility. |
| RoHS Compliance | RoHS compliant (lead-free) | Non-RoHS (contains lead) | RoHS status affects regulatory compliance and solder process; the "Z" suffix denotes the lead-free variant. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Ensures the device operates reliably across the intended environmental conditions. |
| Switching Time (tON/tOFF) | ~14 ns / ~8 ns (typ) | ~14 ns / ~8 ns (typ) | Determines maximum switching speed; matching timing preserves dynamic performance. |

Frequently asked questions
What is the difference between ADG739BRUZ and ADG739BRU?
The ADG739BRUZ is the RoHS-compliant, lead-free (Pb-free) version of the ADG739BRU. Both are dual 4:1 CMOS 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.
Are ADG739BRUZ and ADG739BRU electrically and functionally interchangeable?
Yes. Both devices share the same dual 4:1 multiplexer function, on-resistance, supply range, and 16-lead TSSOP pinout. The only documented difference is the RoHS/lead-free compliance designation of the "Z" suffix, so they are functionally interchangeable in the same PCB footprint.
What is the on-resistance of the ADG739BRUZ/ADG739BRU?
The ADG739 is specified with an on-resistance of approximately 4 Ω (typical) at a single +5 V supply, with a maximum on-resistance specification of about 6 Ω over the operating temperature range, per the Analog Devices ADG739 datasheet.
What supply voltage range do the ADG739BRUZ and ADG739BRU support?
Both devices operate from a single supply of +2.7 V to +5.5 V, or from dual supplies of ±2.7 V to ±5.5 V, as specified in the Analog Devices ADG739 datasheet.
What package do the ADG739BRUZ and ADG739BRU use?
Both parts are supplied in a 16-lead TSSOP (Thin Shrink Small Outline Package), designated by the "RU" code in the part number. The "Z" suffix on ADG739BRUZ indicates the RoHS-compliant, lead-free version of the same TSSOP package.
What is the switching time of the ADG739BRUZ/ADG739BRU?
Per the Analog Devices ADG739 datasheet, the transition time (tTRANSITION) is typically about 14 ns and the break-before-make time delay is typically about 5 ns at a +5 V single supply, with turn-on and turn-off times in the tens of nanoseconds range.
Should I choose ADG739BRUZ or ADG739BRU for a new design?
For new designs, ADG739BRUZ is generally preferred because it is the RoHS-compliant, lead-free variant and supports compliance with current environmental regulations. ADG739BRU may still be used where non-RoHS inventory is acceptable, but both share identical electrical performance.
What are the key applications of the ADG739BRUZ/ADG739BRU?
These dual 4:1 analog multiplexers are used in signal routing, data acquisition systems, audio and video switching, communication systems, and battery-powered instrumentation, where low on-resistance and low power consumption in a small TSSOP package are required.
