Product details
Overview
ISL54055IRUZ-T from Intersil is a normally closed (NC), ultra-low ON-resistance, single-pole single-throw (SPST) analog switch optimized for battery-powered portable systems. It operates from a single +1.8V to +5.5V supply, delivers 0.34Ω rON at 5V, 12ns tON/tOFF, and supports 1.8V logic compatibility - enabling high-fidelity audio/video signal routing in space-constrained mobile phones and medical handhelds.
For engineers reviewing the ISL54055IRUZ-T datasheet, ISL54055IRUZ-T pinout, ISL54055IRUZ-T application, or ISL54055IRUZ-T equivalent, key selection criteria include its NC logic polarity, µTDFN-6 package footprint, 6kV HBM ESD rating, and dual-signal-pin architecture enabling SPST or distribution-mode operation without external components.
Technical Context
The ISL54055IRUZ-T implements a bi-directional, single-control SPST switch with two identical NC signal terminals (pins 1 and 3) simultaneously connected to common (pin 4) when logic input (pin 6) is low. Its sub-1Ω rON across 1.8–5.5V supply range and <15ns switching times are achieved via submicron CMOS process with integrated level-shifting logic.
Unlike standard SPST switches, it supports two distinct configurations: standalone SPST (one signal pin used, other floated) or parallel-connected SPST (both pins tied), reducing effective rON by 50% at 5V. Its analog signal range spans 0V to V+, with ESD protection diodes clamping inputs to V+ and GND.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| rON (5V) | 0.34Ω typical - enables minimal voltage drop and power loss in high-current analog paths |
| tON/tOFF (5V) | 12ns typical - supports fast-switching applications like multi-source audio routing |
| Supply Range | +1.8V to +5.5V - compatible with Li-ion, coin-cell, and regulated 3.3V/5V rails |
| Logic Polarity | Active-low (NC) - output connects when IN ≤ 0.5V, disconnects when IN ≥ 1.4V |
| ESD Rating | >6kV HBM - robust handling in portable device assembly and end-user environments |
| Signal Bandwidth | 72MHz (-3dB, dual-input mode) - preserves integrity of baseband audio and video signals |
| Leakage Current | ±150nA max (full temp range) - critical for precision sensor front-ends and low-power standby modes |
Pinout & Package
ISL54055IRUZ-T uses a 6-lead ultra-thin dual flat no-lead (µTDFN) package measuring 1.2mm × 1.0mm × 0.5mm (PKG DWG L6.1.2x1.0A), optimized for PCB area reduction in ultra-portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3 | NC (Normally Closed Signal Pins) | Both pins connect/disconnect simultaneously to COM under IN control; can be paralleled to halve rON |
| 4 | COM (Common Terminal) | Analog signal path hub - connects to either NC pin based on logic state |
| 6 | IN (Digital Control Input) | Active-low logic interface - TTL/1.8V compatible; drives internal level shifter |
| 2 | GND | Ground reference for analog and digital domains; must be low-impedance for signal integrity |
| 5 | V+ | Single positive supply rail - powers analog switches and logic; sets analog signal ceiling (0V to V+) |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low rON flatness | 0.13Ω max over full analog range at 4.5V - ensures consistent gain and linearity in audio paths |
| Dual NC architecture | Two synchronized signal paths enable redundancy or parallel rON reduction without layout changes |
| 1.8V logic compatibility | Operates with 0.5V/1.4V thresholds at 2.7–3.6V supply - eliminates level shifters in 1.8V I/O systems |
| Low charge injection | 71pC typical (5V) - minimizes glitch-induced errors in precision ADC/DAC multiplexing |
| Pb-free & RoHS compliant | NiPdAu e4 termination - supports lead-free reflow and meets global environmental compliance mandates |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL54050 | Recommended replacement per FN6461; same µTDFN-6 package, but improved rON flatness and lower leakage | Targeted for new designs where long-term supply continuity and enhanced precision are required | Select ISL54050 for production ramp; ISL54055IRUZ-T remains viable for legacy repair or cost-sensitive builds |
| TMUX1574RUE | TI part with 0.5Ω rON (5V), active-high logic, and 1.65–5.5V supply - not NC polarity matched | Suitable for generic SPST routing but requires logic inversion or firmware adaptation | Use only if NC behavior is not mandatory; verify timing and leakage specs against system requirements |
Compared with ISL54055IRUZ-T, ISL54050 offers superior long-term availability and tighter rON flatness, while TMUX1574RUE provides broader voltage support but demands design-level logic adaptation due to opposite control polarity.

FAQ
What is the logic polarity configuration of the ISL54055IRUZ-T?
The ISL54055IRUZ-T is a normally closed (NC) analog switch: the signal paths between pins 1/3 and pin 4 are conductive when the IN pin (pin 6) is logic low (≤0.5V), and open when IN is logic high (≥1.4V). This behavior is explicitly defined in the truth table and pin descriptions of the FN6461 datasheet for ISL54055IRUZ-T.
Does the ISL54055IRUZ-T support rail-to-rail analog signal operation?
Yes, the ISL54055IRUZ-T supports a full analog signal range from 0V to V+, as confirmed in the "Operating Conditions" and "Electrical Specifications" sections of the FN6461 datasheet. This allows undistorted passage of signals spanning the entire supply domain - essential for audio, sensor, and video applications using ISL54055IRUZ-T.
Can both NC pins (1 and 3) of the ISL54055IRUZ-T be used simultaneously?
Yes - pins 1 and 3 are internally synchronized NC terminals that connect/disconnect together to COM (pin 4). When externally tied, their parallel connection reduces effective rON by ~50% (e.g., from 0.34Ω to 0.17Ω at 5V), as documented in the "Detailed Description" section of the ISL54055IRUZ-T datasheet.
What is the thermal resistance and maximum junction temperature for the ISL54055IRUZ-T?
The ISL54055IRUZ-T in its µTDFN-6 package has a typical θJA of 175°C/W and a maximum junction temperature of +150°C, per the "Thermal Information" table on page 3 of the FN6461 datasheet. These values apply specifically to the ISL54055IRUZ-T variant in the L6.1.2x1.0A package.
Is the ISL54055IRUZ-T pin-compatible with the ISL54054IRUZ-T?
Yes - both ISL54055IRUZ-T and ISL54054IRUZ-T share identical µTDFN-6 pinouts (L6.1.2x1.0A), including pin 1 (NC/NO), pin 3 (NC/NO), pin 4 (COM), pin 6 (IN), pin 2 (GND), and pin 5 (V+). However, their logic polarity differs: ISL54054IRUZ-T is NO (active-high), while ISL54055IRUZ-T is NC (active-low).
