What are the key features of ADG3247BRUZ?
- 8 independent 1:1 bus switches in a single 38-pin TSSOP, reducing component count for multi-line bus isolation applications
- 2.3 V to 3.6 V supply range with sub-1 Ω typical on-resistance enables low-distortion signal routing on 3.3 V CMOS data buses
- Active-low enable control with 50 pF rated load capacitance supports high-speed data switching up to hundreds of MHz on PCIe and DDR routing
What is ADG3247BRUZ used for?
The ADG3247BRUZ is used in server motherboards, test equipment, and networking switch cards for isolating or multiplexing 8-bit data buses between processors and memory or peripheral controllers. Its low on-resistance and 3.3 V CMOS compatibility make it suitable for DDR address bus switching, PCIe riser card routing, and JTAG isolation in multi-board systems. The 38-pin TSSOP package allows compact placement in dense bus routing regions of high-layer-count PCBs.

Frequently Asked Questions
How many switch channels does the ADG3247BRUZ integrate and what bus widths can it handle?
The ADG3247BRUZ integrates 8 independent 1:1 bus switches, making it directly suitable for routing an 8-bit parallel data bus with a single enable control. For 16-bit or 32-bit buses, two or four devices can be placed in parallel sharing a common active-low enable, keeping the PCB layout symmetric and routing clean on multi-layer boards with 50 pF load lines.
What supply voltage range does the ADG3247BRUZ support, and is it compatible with 2.5 V logic?
The ADG3247BRUZ operates from 2.3 V to 3.6 V, making it compatible with 2.5 V and 3.3 V CMOS logic families. However, it is not rated for 1.8 V or 5 V operation; designs using those rails require a different ADG family variant. At 2.5 V supply, on-resistance rises slightly but typically remains below 5 Ω, which is acceptable for most low-frequency bus isolation tasks with 50 pF bus capacitance.
For a server backplane design, what makes the ADG3247BRUZ a practical bus isolation choice?
The ADG3247BRUZ provides 8 channels of bi-directional bus switching with active-low enable in a 38-pin TSSOP (0.65 mm pitch), allowing dense parallel placement along a 64-bit or 32-bit bus. Its low charge injection and sub-nanosecond switching transient keep signal integrity acceptable on backplane traces running at tens of MHz with 50 pF distributed load, while the 2.3 V to 3.6 V range covers common LVTTL and 3.3 V CMOS bus standards used in server I/O expansion slots.
Does the ADG3247BRUZ support RoHS compliance, and what should procurement teams note about end-of-life status?
The ADG3247BRUZ (BRUZ suffix) is not Pb-free and carries a JESD-609 code of e3, indicating tin-lead solder terminations. For RoHS-compliant designs, engineers should use the B-grade or alternative package variants that carry a Pb-free finish. With a YTEOL (years to end-of-life) of 10 years from the last production date, procurement teams should factor in a last-time-buy window and consider stocking 3–5 years of production volume before obsolescence to avoid respin costs.
