Product details
Overview
ISL54233IRUZ-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 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 streams onto a shared headphone/data jack.
For engineers reviewing the ISL54233IRUZ-T datasheet, ISL54233IRUZ-T pinout, ISL54233IRUZ-T application, or ISL54233IRUZ-T equivalent, this device requires attention to its dual SP3T architecture, ultra-thin 12-lead UTQFN (2.2mm×1.4mm) package, low 2.8pF COM ON capacitance at 240MHz, break-before-make timing (30ns), and power-off protection enabling safe VBUS fault handling without external components.
Technical Context
The ISL54233IRUZ-T implements two independent SP3T analog switches (six total 6Ω bidirectional channels) controlled by C0/C1 logic inputs, supporting four modes: all-off (C0=C1=0), USB/DV#1 (C0=1,C1=0), USB/DV#2 (C0=0,C1=1), and USB/DV#3 (C0=C1=1). Its internal 4MΩ pull-down resistors allow floating control pins to default to logic low.
It features integrated fault protection: COM± and D± pins tolerate up to 5.5V regardless of VDD state, and power-off isolation ensures no current flows through disabled channels when VDD = 0V. The device meets USB 2.0 short-circuit requirements without external clamps or resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |

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 switch with 6Ω rON, but only 500MHz bandwidth and no -2V COM swing capability | Lacks wired-OR audio mode and fails USB 2.0 high-speed eye mask at 480Mbps due to higher jitter | Choose TS3USB30E only if bandwidth demand is ≤240MHz and audio integration is not required |
| MAX4989ETE+ | Higher 10Ω rON, 1.2GHz bandwidth, and 5.5V tolerant I/O, but requires dual supply (3.3V + 1.8V) and larger 16-pin TQFN | Supports wider voltage rails but adds complexity in single-supply portable designs | Select MAX4989ETE+ only when interfacing with 5V legacy peripherals and layout space permits larger package |

FAQ
What is the maximum data rate supported by the ISL54233IRUZ-T?
The ISL54233IRUZ-T supports USB 2.0 high-speed data rates up to 480Mbps, validated by eye pattern testing (Figures 15–16 in FN7918). Its 1.6GHz -3dB bandwidth, 210ps total jitter, and 75ps skew ensure compliance with USB 2.0 signal quality specifications when routing differential signals.
Does the ISL54233IRUZ-T require external components for USB 2.0 short-circuit protection?
No. The ISL54233IRUZ-T complies with USB 2.0 short-circuit requirements without external components. Its COM± and D± pins tolerate up to 5.5V, and internal fault protection isolates VBUS faults even when VDD is unpowered-eliminating need for external TVS diodes or series resistors.
Can the ISL54233IRUZ-T pass signals below ground?
Yes. The COM± pins accept input swings down to -2V, enabling wired-OR audio connections in the all-switches-OFF state (C0=C1=0). This allows direct coupling of audio codecs to the COM node without level-shifting circuitry, preserving analog signal fidelity.
What package type is used for the ISL54233IRUZ-T?
The ISL54233IRUZ-T uses a 12-lead ultra-thin QFN (UTQFN) package measuring 2.2mm × 1.4mm with 0.4mm pitch and an exposed thermal pad (PKG drawing L12.2.2x1.4A). This compact footprint is optimized for space-constrained portable designs.
How does the ISL54233IRUZ-T handle power-off conditions?
When VDD = 0V, the ISL54233IRUZ-T enters power-off protection mode: all switches isolate, COM± and D± pins tolerate up to 5.25V, and leakage remains below 1µA. This prevents battery drain and protects downstream circuitry during system shutdown or battery removal.
