Product details
Overview
ISL76120ARTZ-TR5303 from Intersil is an automotive-grade dual 2:1 USB 2.0 multiplexer IC designed to switch between high-speed (480Mbps) and full-speed (12Mbps) USB transceivers in portable media docking systems. It features two SPDT switches configured as DPDT, operates from a single 2.7V–5.5V supply, supports rail-to-rail signal swing on FSx paths, and delivers 880MHz HSx bandwidth with -98dB off-isolation at 100kHz. It enables seamless source selection in infotainment head units connecting PMPs or iPods to a single USB host.
For engineers reviewing the ISL76120ARTZ-TR5303 datasheet, ISL76120ARTZ-TR5303 pinout, ISL76120ARTZ-TR5303 application, or ISL76120ARTZ-TR5303 equivalent, key selection criteria include AEC-Q100 qualification, 1.8V logic compatibility under 2.7V–3.6V supply, enable-controlled break-before-make switching, ultra-low 60nA operating current, and TDFN package thermal performance (θJA = 50°C/W).
Technical Context
The ISL76120ARTZ-TR5303 implements a dual-path analog switch architecture: FSx (FSD1/FSD2) channels optimized for 0–3.6V full-speed differential signaling with 550MHz -3dB bandwidth and <10Ω rON, while HSx (HSD1/HSD2) channels deliver 480Mbps high-speed compliance via low-capacitance design (6pF OFF), 880MHz bandwidth, and matched 4.5–9Ω rON across 0–400mV signal range. Both paths support bidirectional operation and rail-to-rail voltage swing.
Logic control uses IN and EN pins with defined thresholds (VINL ≤0.5V, VINH ≥1.4V) and internal 4MΩ EN pull-down. The truth table defines three states: FSx active/HSx off (IN=0, EN=1), HSx active/FSx off (IN=1, EN=1), and all-switches-off (EN=0). Break-before-make timing ensures no signal contention during mode transitions.

Pinout & Package
The ISL76120ARTZ-TR5303 is housed in a 10-lead 3mm × 3mm TDFN package with exposed thermal pad (PKG DWG # L10.3x3A), supporting high-density PCB layouts and efficient heat dissipation in space-constrained automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Power Supply Input | Single 2.7–5.5V bias rail; requires local 0.01µF–0.1µF decoupling to GND for noise suppression. |
| IN (Pin 2) | Mode Select Control | Determines active path: logic "0" enables FSx, logic "1" enables HSx (only when EN = 1). |
| COMD1 / COMD2 (Pins 3, 4) | Common USB Differential Ports | Connect to upstream USB host D+/D− lines; shared by both HSx and FSx paths. |
| GND (Pin 5) | Ground Reference | Primary return path; exposed paddle must be soldered to PCB ground plane for thermal and EMI performance. |
| FSD2 / FSD1 (Pins 6, 7) | Full-Speed Differential Inputs | Interface with full-speed USB transceiver (e.g., PMP baseband IC); rail-to-rail capable (0–3.6V). |
| HSD2 / HSD1 (Pins 8, 9) | High-Speed Differential Inputs | Interface with high-speed USB PHY; optimized for 0–400mV signals with low capacitance (6pF OFF). |
| EN (Pin 10) | Global Enable | Logic "0" forces all switches into high-impedance state; internal 4MΩ pull-down simplifies control logic. |

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 |
|---|---|---|---|
| TS3USB30E | Single 2:1 mux, 5-pin SOT-23; lacks dual-path integration and AEC-Q100 qualification. | Targeted at consumer portable devices, not automotive environments. | Use only for non-automotive, cost-sensitive, space-constrained designs where dual-path switching is unnecessary. |
| MAX14533 | Quad SPST, 16-pin TQFN; supports 480Mbps but requires external logic for DPDT behavior and has no integrated enable. | Suitable for custom USB routing in industrial test equipment, not pre-validated automotive docking. | Select when flexible channel assignment is required and AEC-Q100 compliance can be achieved via system-level validation. |
Compared with TS3USB30E and MAX14533, the ISL76120ARTZ-TR5303 provides integrated dual-path control, automotive qualification out-of-box, and simplified enable logic-reducing BOM count and validation effort for infotainment docking applications.

FAQ
What USB 2.0 data rates does the ISL76120ARTZ-TR5303 support?
The ISL76120ARTZ-TR5303 supports both full-speed (12Mbps) and high-speed (480Mbps) USB 2.0 signaling. Its FSx switches handle 0–3.6V full-speed differential signals with 550MHz bandwidth, while HSx switches pass 0–400mV high-speed signals with 880MHz bandwidth and meet USB 2.0 eye diagram specifications. The ISL76120ARTZ-TR5303 achieves this through dedicated analog path optimization-not generic switching.
How does the ISL76120ARTZ-TR5303 ensure signal integrity during USB switching?
The ISL76120ARTZ-TR5303 ensures signal integrity via low HSx OFF capacitance (6pF), -98dB off-isolation at 100kHz, and 50ps skew between HSD1/HSD2 channels. Its break-before-make timing (7ns min) prevents bus contention, and its 880MHz -3dB bandwidth preserves edge fidelity at 480Mbps. These parameters are measured and specified in the FN6711 datasheet for the ISL76120ARTZ-TR5303 under defined load conditions.
Is the ISL76120ARTZ-TR5303 qualified for automotive use?
Yes, the ISL76120ARTZ-TR5303 is AEC-Q100 Grade 2 qualified and manufactured under TS16949 quality systems. It operates across -40°C to +105°C, features >8.5kV HBM ESD rating, and is validated for automotive thermal cycling, humidity, and lifetime reliability. This qualification applies specifically to the ISL76120ARTZ-TR5303 part number per Intersil's product information page.
What logic voltage levels are compatible with the ISL76120ARTZ-TR5303 control pins?
The ISL76120ARTZ-TR5303 IN and EN pins are 1.8V logic compatible when operated with a 2.7V–3.6V supply: logic "0" is defined as ≤0.5V and logic "1" as ≥1.4V. This allows direct interfacing with 1.8V/3.3V microcontrollers without level shifters. The EN pin includes an internal 4MΩ pull-down resistor, simplifying default-off configuration for the ISL76120ARTZ-TR5303.
Does the ISL76120ARTZ-TR5303 support charge control functionality?
Yes, the ISL76120ARTZ-TR5303 supports USB charge control by enabling safe VBUS negotiation prior to data link establishment. Its all-switches-off mode (EN = 0) isolates both HSx and FSx paths, allowing charge detection circuitry to identify device type (e.g., BC1.2, DCP) before enabling data communication-preventing VBUS conflicts and ensuring compliance in PMP docking applications using the ISL76120ARTZ-TR5303.
