Product details
Overview
ISL54200IRZ from Intersil is a dual 2:1 USB 2.0 analog multiplexer IC designed for portable battery-powered devices requiring dynamic switching between USB high-speed (480Mbps) and full-speed (12Mbps) transceivers. It integrates two SPDT switches configured as a DPDT, with 4.5Ω HSx switches optimized for high-bandwidth signal integrity and 7Ω FSx switches supporting rail-to-rail 0V–3.6V operation. It operates from a single 2.7V–5.5V supply and features 1.8V logic compatibility at 2.7V–3.6V supply.
For engineers reviewing the ISL54200IRZ datasheet, ISL54200IRZ pinout, ISL54200IRZ application, or ISL54200IRZ equivalent, key selection considerations include its dual-path USB 2.0 signal routing capability, break-before-make timing (7ns), -98dB off-isolation at 100kHz, and support for both TDFN and µTQFN packages in portable media designs.
Technical Context
The ISL54200IRZ implements two independent switch paths: HSx (HSD1/HSD2) optimized for 480Mbps differential signaling with 880MHz -3dB bandwidth and 6pF OFF capacitance, and FSx (FSD1/FSD2) tuned for 12Mbps full-speed compliance with 550MHz bandwidth and 9pF OFF capacitance. Each path supports bidirectional rail-to-rail analog signal swing.
Control logic uses an enable (EN) pin to globally open all switches and an IN pin to select between HSx (IN ≥1.4V) and FSx (IN ≤0.5V) paths under 2.7V–3.6V supply. The device guarantees 50ps skew and 210ps total jitter on HSx paths, meeting USB 2.0 high-speed eye mask requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB 2.0 multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS3USB221ERUAR | Single 2:1 mux (not dual); 6Ω rON; 850MHz bandwidth; 10-pin UQFN (2.1×1.6mm) | Supports only one differential pair; requires two devices for full ISL54200IRZ functionality | Choose when board space is critical and only one USB path needs switching |

FAQ
What is the maximum signal voltage range supported by the ISL54200IRZ HSx switches?
The ISL54200IRZ HSx switches (HSD1/HSD2) support a maximum analog signal range of -1.5V to VDD. When operated at VDD = 3.3V, this allows differential signals from -1.5V to 3.3V, covering the USB 2.0 high-speed nominal 0–400mV common-mode window with margin. Exceeding these limits risks damage or degraded performance. The ISL54200IRZ datasheet specifies clamping behavior for out-of-range signals but recommends staying within these bounds for reliable USB 2.0 compliance.
Does the ISL54200IRZ require external pull-up or pull-down resistors on its IN and EN pins?
The ISL54200IRZ has an internal 4MΩ pull-down resistor on the EN pin, so no external pull-down is required-EN can be left floating to default to logic low. However, the IN pin has no internal termination and must be actively driven high or low; leaving it floating may cause undefined switching behavior. The ISL54200IRZ truth table confirms IN is "don't care" only when EN = 0, but stable logic states are mandatory when EN = 1 to ensure correct HSx/FSx path selection.
Can the ISL54200IRZ be used with a 5V supply while maintaining USB 2.0 signal integrity?
Yes, the ISL54200IRZ supports VDD from 2.7V to 5.5V, and its FSx switches maintain rail-to-rail operation up to VDD = 5.5V. However, for USB 2.0 high-speed (480Mbps) signaling, the HSx path is optimized for 0–400mV differential swing-using 5V VDD does not alter this small-signal range. The ISL54200IRZ's 880MHz bandwidth and 6pF OFF capacitance ensure signal integrity remains intact at 5V supply, provided proper PCB layout (controlled impedance, short traces) is followed per the datasheet guidelines.
How does the ISL54200IRZ handle USB hot-plug events during mode switching?
The ISL54200IRZ facilitates safe USB hot-plug handling via its dedicated EN pin: driving EN low places all switches in high-impedance state, effectively disconnecting both HSx and FSx paths from the common USB connector (COMD1/COMD2). This "all-off" mode prevents bus contention during transitions and allows the host to cleanly enumerate the newly selected transceiver. The ISL54200IRZ's -98dB off-isolation at 100kHz further suppresses leakage that could trigger false connect/disconnect detection during switching.
Is the thermal pad (PD) on the ISL54200IRZ package electrically connected internally?
No, the thermal pad (PD) on the ISL54200IRZ TDFN package is not electrically connected to any internal circuit node-it serves solely as a thermal conduction path. The datasheet explicitly states PD should be tied to GND or left floating; grounding it improves thermal performance (θJC = 16.5°C/W) and reduces EMI, but it is not required for electrical functionality. Leaving PD unconnected does not affect ISL54200IRZ operation, though thermal derating must be applied per θJA = 55°C/W if not soldered to a GND plane.
