Overview
ISL54220IUZ-TS2568 from Intersil is a single-supply, dual 2:1 USB 2.0 high-speed multiplexer IC configured as a DPDT analog switch. It supports 480Mbps high-speed and 12Mbps full-speed USB signaling, features 6Ω ON-resistance at 3.3V, 742MHz −3dB bandwidth, and operates from 2.7V to 5.5V for portable media device USB port switching.
For engineers reviewing the ISL54220IUZ-TS2568 datasheet, ISL54220IUZ-TS2568 pinout, ISL54220IUZ-TS2568 application, or ISL54220IUZ-TS2568 equivalent, key selection criteria include USB 2.0 signal integrity preservation, rail-to-rail 0–400mV HS/0–3.3V FS analog range compatibility, 1.8V logic support, OE-controlled switch disable, and overvoltage tolerance up to 5.5V on D+/D− pins.
Technical Context
The ISL54220IUZ-TS2568 integrates four bi-directional high-speed switches (HSD1±, HSD2±) forming two independent SPDT channels in a DPDT configuration. Its submicron CMOS process delivers 4.2pF ON-capacitance at 240MHz and <50ps output skew - critical for maintaining USB 2.0 eye diagram integrity with minimal edge distortion.
It implements dedicated fault protection enabling D+/D− pins to withstand 5.5V overvoltage while VDD = 0V (isolated) or VDD = 2.7–5.5V (pass-through on active channel), satisfying USB 2.0 short-circuit requirements without external components. Logic inputs are 1.8V-compatible when powered from 2.7–3.6V supplies.

Pinout & Package
ISL54220IUZ-TS2568 is packaged in a 10-lead MSOP (Mini Small Outline Package) with exposed thermal pad (PD), measuring 3.0mm × 4.9mm × 1.1mm. Pin 1 is marked with dot; PD must be tied to GND for optimal thermal performance and ESD robustness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 10) | Power supply input | Accepts 2.7–5.5V DC; requires local 0.01µF–0.1µF decoupling capacitor to GND for noise suppression. |
| SEL (Pin 1) | Channel select control | Logic "0" enables HSD1± path; logic "1" enables HSD2± path; only active when OE = "0". |
| HSD1+ (Pin 2), HSD1− (Pin 8) | High-speed Channel 1 differential inputs | Connect to first USB transceiver's D+/D− outputs; bidirectional, rail-to-rail capable (0–400mV HS / 0–3.3V FS). |
| HSD2+ (Pin 3), HSD2− (Pin 7) | High-speed Channel 2 differential inputs | Connect to second USB transceiver's D+/D− outputs; identical electrical specs to HSD1±. |
| D+ (Pin 4), D− (Pin 6) | Common USB connector outputs | Drive standard USB Type-A/B receptacle; tolerate 5.5V fault voltage even when VDD = 0V. |
| GND (Pin 5) | Ground reference | Primary return path for analog and digital currents; connects to thermal pad (PD) for thermal dissipation. |
| OE (Pin 9) | Output enable | Logic "1" forces all switches into high-impedance OFF state - essential for glitch-free channel switching and USB enumeration reset. |
Key Features
| Feature | Design Value |
|---|---|
| USB 2.0 compliance without external components | Fault protection on D+/D− pins handles 5.5V VBUS shorts during power-off or power-on states - eliminates need for discrete overvoltage clamps. |
| Rail-to-rail analog signal swing | Supports full 0–400mV high-speed and 0–3.3V full-speed USB differential ranges - preserves signal fidelity across entire operating voltage window. |
| Break-before-make switching | 10ns minimum delay prevents momentary shorting between HSD1 and HSD2 paths - avoids bus contention and enumeration failures. |
| Low dynamic skew | <50ps output skew between D+ and D− paths - maintains differential timing margin required for 480Mbps eye compliance. |
| Ultra-low ON-capacitance | 4.2pF at 240MHz - minimizes signal reflection and jitter accumulation in high-frequency USB traces. |
