Product details
Overview
ISL54233IRTZ-T 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 analog swing, -2V COM pin tolerance, and 1.6GHz -3dB bandwidth. It operates from a single 2.7V–4.6V supply and is used in smartphone headphone jack consolidation.
For engineers reviewing the ISL54233IRTZ-T datasheet, ISL54233IRTZ-T pinout, ISL54233IRTZ-T application, or ISL54233IRTZ-T equivalent, key selection criteria include differential channel count (3× SPDT), ON-resistance matching (≤0.55Ω), low ON-capacitance (2.8pF @240MHz), fault-tolerant COM pins (−2V to 5.5V), and TQFN-12 package compatibility with high-frequency PCB layout requirements.
Technical Context
The ISL54233IRTZ-T implements dual SP3T (single-pole, triple-throw) switch architecture with six bidirectional 6Ω data switches, enabling selection among three differential signal sources onto shared COM± outputs. Its CMOS process delivers sub-1ns skew (75ps typ) and 210ps total jitter at 480Mbps, meeting USB 2.0 eye mask compliance with minimal edge distortion.
Logic control uses two CMOS-compatible inputs (C0/C1) with internal 4MΩ pull-downs, supporting tri-state/floating logic and overvoltage-tolerant operation up to 5.25V independent of VDD. The device features all-switches-OFF mode (C0=C1=0), power-off protection (VBUS isolation at VDD=0V), and COM-pin overvoltage tolerance to 5.5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7V to 4.6V single supply - enables direct battery/LDO connection in portable systems without level-shifting. |
| -3dB Bandwidth | 1.6GHz - preserves signal integrity for USB 2.0 high-speed (480Mbps) and digital video transmission. |
| ON-Resistance (rON) | 6Ω typ @2.7V - ensures minimal insertion loss and voltage drop across differential paths. |
| rON Matching | ≤0.55Ω max - maintains amplitude balance between differential pairs critical for common-mode rejection. |
| COM Pin Range | −2V to 5.5V - supports wired-OR audio integration and withstands USB VBUS shorts during fault conditions. |
| OFF Isolation | −32dB @240MHz - suppresses crosstalk between inactive channels in multi-source routing. |
| Switching Time | 125ns typ - enables fast mode transitions without disrupting real-time data streams. |
Pinout & Package
ISL54233IRTZ-T is packaged in a 12-lead 3mm×3mm thin quad flat no-lead (TQFN) with exposed thermal pad. The package is RoHS-compliant, moisture-sensitive level (MSL) 3, and optimized for high-frequency layout with controlled-impedance trace routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 12 | Differential Input (3D+, 2D-, 2D+, 3D−) | Three independent differential input pairs; each pair routed through dedicated 6Ω switch to COM±. |
| 4, 5 | Differential Input (1D−, 1D+) | First USB/DV source path; compatible with 0–400mV USB HS signaling and rail-to-rail UART. |
| 7, 8 | Common Output (COM+, COM−) | Shared differential output node; accepts −2V to VDD swing and tolerates 5.5V faults. |
| 9, 10 | Digital Control (C1, C0) | Two-bit binary select; internally pulled down (4MΩ); logic-high ≥1.4V, float = logic-low. |
| 6 | GND | Signal and power ground reference; connects to PCB ground plane and thermal pad. |
| 11 | VDD | Single power supply input (2.7–4.6V); requires local 0.01µF RF decoupling capacitor. |
| PAD | Thermal Pad | Exposed copper pad on underside; must be soldered to solid GND plane for thermal and EMI performance. |
Key Features
| Feature | Design Value |
|---|---|
| USB 2.0 Short-Circuit Compliance | No external components needed to meet USB 2.0 short-circuit requirements - reduces BOM cost and board area. |
| Rail-to-Rail Signal Swing | Supports full-speed USB (12Mbps) and UART signals across entire supply range - eliminates need for biasing networks. |
| Power-Off Protection | Isolates COM pins from D± when VDD = 0V - prevents back-powering and protects downstream transceivers. |
| Low ON Capacitance | 2.8pF @240MHz - minimizes high-frequency loading and preserves signal rise/fall times. |
| Overvoltage-Tolerant Logic Inputs | C0/C1 accept up to 5.25V regardless of VDD - simplifies interface with higher-voltage controllers or level-shift-free GPIO. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS3USB30EIRGER | Single-supply 3:1 USB 2.0 switch; 6Ω rON, 1.2GHz bandwidth, 10-pin UQFN - lower bandwidth and fewer pins than ISL54233IRTZ-T. | Targeted at basic USB-only routing; lacks COM-pin negative swing (−2V) and digital video support. | Choose for cost-sensitive USB-only designs where 1.2GHz bandwidth suffices and audio/video consolidation is not required. |
| MAX4989ETE+ | 3:1 differential mux with 1.8GHz bandwidth, 5.5Ω rON, 16-pin TQFN - larger footprint and higher supply current (12µA vs 6.5µA). | Includes integrated ESD protection (±15kV HBM); rated for industrial temp (−40°C to +125°C) but no COM-pin −2V capability. | Prefer for harsh environments requiring extended temperature range and robust ESD, accepting larger size and higher quiescent current. |
Compared with TS3USB30EIRGER and MAX4989ETE+, the ISL54233IRTZ-T uniquely combines −2V COM swing for wired-OR audio, 1.6GHz bandwidth for digital video, ultra-low 6.5µA supply current in all modes, and 3mm×3mm TQFN packaging - making it optimal for space-constrained portable media consolidation.

FAQ
What is the maximum signal frequency supported by the ISL54233IRTZ-T?
The ISL54233IRTZ-T supports a −3dB bandwidth of 1.6GHz, verified per Figure 19 in the FN7918 datasheet. This enables reliable transmission of USB 2.0 high-speed (480Mbps) data and digital video signals with minimal phase and edge distortion. Performance is characterized at 25°C with 50Ω termination and 0.01µF VDD decoupling.
Does the ISL54233IRTZ-T support negative voltage swings on its COM pins?
Yes, the ISL54233IRTZ-T COM+ and COM− pins tolerate signals from −2V to 5.5V, as specified in the Absolute Maximum Ratings table (Page 4). This allows wired-OR connection of audio codecs in the ALL SWITCHES OFF state (C0=C1=0), a key feature for headphone jack consolidation in portable media players.
What package type is used for the ISL54233IRTZ-T?
The ISL54233IRTZ-T uses a 12-lead 3mm×3mm thin quad flat no-lead (TQFN) package, identified as L12.3x3A in the Ordering Information table (Page 3). It includes an exposed thermal pad that must be soldered to a PCB ground plane for thermal management and signal integrity.
How does the ISL54233IRTZ-T handle power-off protection?
When VDD = 0V, the ISL54233IRTZ-T isolates COM pins from all D± inputs (1D±/2D±/3D±), limiting COMx leakage to ≤1µA (Page 5, Power OFF COMx Current). This prevents back-powering of upstream transceivers during battery removal or shutdown - a core safety feature confirmed in the Fault Protection section (Page 8).
Can the ISL54233IRTZ-T be used for USB 2.0 full-speed (12Mbps) applications?
Yes, the ISL54233IRTZ-T fully supports USB 2.0 full-speed (12Mbps) operation, as explicitly stated in the Features list (Page 1) and validated by the 12Mbps eye pattern in Figure 17. Its rail-to-rail signal swing and low ON-resistance (6Ω typ) ensure minimal distortion for UART and full-speed USB signals without external biasing.
