Product details
Overview
ISL54233IRUZ-T7A from Renesas Electronics is a wideband differential 3:1 multiplexer IC designed for high-speed signal routing in portable media devices. It supports USB 2.0 high-speed (480Mbps) and full-speed (12Mbps) data, digital video, and UART signals across three differential input pairs (1D±/2D±/3D±), with rail-to-rail switching, -2V COM pin tolerance, and 1.6GHz -3dB bandwidth. It operates from a single 2.7V–4.6V supply and is used in MP4 players, smartphones, and tablets to consolidate multiple data sources onto a shared headphone/data jack.
For engineers reviewing the ISL54233IRUZ-T7A datasheet, ISL54233IRUZ-T7A pinout, ISL54233IRUZ-T7A application, or ISL54233IRUZ-T7A equivalent, key selection considerations include its 12-lead UTQFN (2.2mm×1.4mm) package, dual SP3T architecture, all-switches-OFF mode, power-off protection, and compliance with USB 2.0 short-circuit requirements without external components.
Technical Context
The ISL54233IRUZ-T7A implements two independent SP3T analog switches (six total 6Ω bidirectional channels) configured as a differential 3:1 mux. Its CMOS design enables low ON-capacitance (2.8pF at 240MHz) and high bandwidth (1.6GHz), preserving signal integrity for 480Mbps USB eye patterns and minimizing skew (75ps) and jitter (210ps).
Control logic uses C0/C1 pins with internal 4MΩ pull-downs; logic thresholds are defined at VDD = 2.7V–3.6V (VIL ≤ 0.5V, VIH ≥ 1.4V). The device supports wired-OR audio mode when both controls are low, and provides fault tolerance: COM/IO pins withstand up to 5.5V while VDD = 0V, enabling robust power-off protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 12 | 3D+, 3D− | Differential input pair for third data source (e.g., USB 3/DV channel); bidirectional, 6Ω rON. |
| 2, 3 | 2D−, 2D+ | Differential input pair for second data source (e.g., USB 2/DV channel); matches 1D±/3D± performance. |
| 4, 5 | 1D−, 1D+ | Differential input pair for first data source (e.g., USB 1/DV channel); primary path for default selection. |
| 6 | GND | Ground reference for analog and digital circuitry; must be low-impedance for noise control. |

| 11 | VDD | Single power supply input (2.7–4.6V); requires local 0.01µF RF decoupling capacitor. |
| PAD | Thermal Pad | Exposed metal pad on underside; must be soldered to PCB ground plane for thermal dissipation and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| USB 2.0 Short-Circuit Compliance | Meets USB 2.0 specification without external protection components, reducing BOM count and layout area. |
| All Switches OFF Mode | C0 = C1 = low disables all six channels simultaneously, enabling safe audio codec sharing on COM pins. |
| Rail-to-Rail Signal Swing | Supports full-speed USB (12Mbps) and UART signals across entire supply range (−1V to VDD), eliminating level shifters. |
| Power-Off Protection | Isolates COM/IO pins from D± channels when VDD = 0V, preventing back-drive damage during hot-plug events. |
| Overvoltage Tolerance | COM± and all D± pins rated to 5.5V - survives VBUS shorts and transient faults without latch-up or degradation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS3USB30E | Single-supply 3:1 USB 2.0 mux (2.5V–4.3V), 6Ω rON, 1.2GHz BW, 14-pin TSSOP - larger footprint, no −2V COM swing. | Lacks wired-OR audio support and overvoltage tolerance; requires external ESD protection for USB compliance. | Choose for cost-sensitive designs where board space and audio integration are secondary priorities. |
| MAX4989ETE+ | 3:1 differential mux with integrated USB 2.0 ESD protection (±15kV HBM), 5.5Ω rON, 1.4GHz BW, 16-pin TQFN - higher pin count, no power-off isolation. | Includes robust ESD clamps but lacks all-switches-OFF mode and COM-level fault isolation during VDD=0. | Prefer when system-level ESD robustness is critical and power sequencing is tightly controlled. |
Compared with TS3USB30E and MAX4989ETE+, the ISL54233IRUZ-T7A uniquely combines −2V COM swing for wired-OR audio, true power-off isolation, and USB 2.0 short-circuit compliance in a 2.2mm×1.4mm UTQFN - making it optimal for space-constrained, multi-function portable designs requiring mixed-signal consolidation.

Does the ISL54233IRUZ-T7A support power-off protection when VDD = 0V?
Yes, the ISL54233IRUZ-T7A provides true power-off protection: when VDD = 0V and C0/C1 are floating, all switches remain OFF, isolating COM± from D± channels. Input/output pins tolerate up to 5.25V under this condition, preventing back-drive damage during hot-plug events - a key feature confirmed in Absolute Maximum Ratings and Detailed Description sections of FN7918.
Can the ISL54233IRUZ-T7A be used for audio signal mixing in wired-OR configuration?
Yes, the ISL54233IRUZ-T7A supports wired-OR audio mixing in All Switches OFF mode (C0 = C1 = low).
