Product details
Overview
ISL54062IRTZ-T from Intersil is a dual SPDT analog switch optimized for audio signal routing in battery-powered portable devices. It delivers sub-ohm ON-resistance (0.57 Ω at 4.3 V), negative signal swing down to 6.5 V below V+, and integrated click-and-pop elimination circuitry - enabling clean audio switching in MP3 players and mobile phones.
For engineers reviewing the ISL54062IRTZ-T datasheet, ISL54062IRTZ-T pinout, ISL54062IRTZ-T application, or ISL54062IRTZ-T equivalent, key selection criteria include guaranteed break-before-make timing, rON matching ≤30 mΩ, THD+N of 0.02% at 32 Ω, single-supply operation from +1.8 V to +6.5 V, and compatibility with 1.8 V logic inputs up to +3 V supply.
Technical Context
The ISL54062IRTZ-T implements a committed dual SPDT architecture with independent IN1/IN2 control, supporting two normally open (NO1/NO2) and two normally closed (NC1/NC2) paths per channel. Its internal level shifters translate 1.8 V logic inputs into full-rail CMOS gate drive across the 1.8–6.5 V supply range.
Click-and-pop suppression uses complementary shunt switches tied to NOx/NCx pins, activated opposite the main switch state and discharging transients through ~140 Ω to GND. The device guarantees break-before-make delay ≤30 ns over temperature and maintains rON flatness ≤0.5 Ω at 2.7 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON-resistance (rON) | 0.57 Ω at V+ = 4.3 V - enables low insertion loss in audio paths with minimal voltage drop under 100 mA load |
| rON matching | ≤30 mΩ between channels - ensures balanced signal routing in stereo or differential applications |
| Turn-on/off time | tON = 43 ns / tOFF = 23 ns at 4.3 V - supports fast multiplexing without audible artifacts in real-time audio switching |
| Negative signal swing | Up to 6.5 V below V+ - allows AC-coupled audio signals with DC bias to pass unclipped (e.g., –1.5 V to +5 V at V+ = 5 V) |
| THD+N | 0.02% at 20 Hz–20 kHz, 32 Ω load - preserves high-fidelity audio integrity with negligible harmonic distortion |
| Supply range | +1.8 V to +6.5 V - supports direct integration with Li-ion, Li-poly, and regulated 3.3 V/5 V rails without level translation |
| Digital input compatibility | 1.8 V logic-compatible up to +3 V supply - eliminates need for external level shifters when driven by low-voltage microcontrollers |
Pinout & Package
ISL54062IRTZ-T is packaged in a Pb-free 10-lead 3×3 mm TDFN (L10.3x3A) with exposed thermal pad. Pin 1 is marked by a dot; top-view pinout matches datasheet Figure 1 (TDFN).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive power supply rail | Accepts +1.8 V to +6.5 V; requires local 0.1 µF decoupling to GND for stable switching performance |
| GND | Ground reference | Return path for analog and digital currents; must be low-impedance connection to minimize noise coupling |
| IN1, IN2 | Digital control inputs | CMOS-compatible logic inputs; threshold defined as VINL ≤ 0.5 V / VINH ≥ 1.6 V at 4.3 V supply |
| COM1, COM2 | Analog common terminals | Switch output nodes; support bidirectional signal flow and handle ±300 mA continuous current |
| NO1, NO2 | Normally open analog inputs | Connected to COMx when corresponding INx = 1; feature integrated shunt path for click/pop suppression |
| NC1, NC2 | Normally closed analog inputs | Connected to COMx when corresponding INx = 0; also include active shunt path during NOx conduction |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Ensures no momentary short between NCx and NOx during switching - critical for preventing audio pops and cross-channel coupling |
| Integrated click-and-pop elimination | Active shunt impedance (~140 Ω) on NOx/NCx pins discharges DC transients before reaching speaker load, eliminating audible artifacts |
| rON flatness ≤ 0.5 Ω | Maintains consistent gain and linearity across full analog signal range (e.g., –3.8 V to +2.7 V at V+ = 2.7 V), minimizing distortion |
| ESD robustness | HBM rating >6 kV - protects against handling damage in portable assembly environments without external protection diodes |
| Low leakage | ICOM(ON) ≤ 0.7 µA over temperature - prevents DC offset buildup at high-impedance preamp inputs or capacitive sensor interfaces |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMUX1574RTER | Higher rON (1.3 Ω typical at 3.3 V), no integrated click/pop circuitry, supports 1.08–4.5 V supply | Lacks audio-specific transient suppression; requires external RC network for pop mitigation in speaker paths | Preferred where ultra-low power (<10 nA IQ) outweighs audio performance requirements |
| ADG884BRMZ-REEL7 | Lower rON (0.45 Ω at 5 V) but no negative swing capability; max analog range limited to GND–V+ | Cannot pass signals below ground - unsuitable for AC-coupled audio with DC bias unless external level-shifting is added | Selected when system operates strictly within 0–V+ signal range and maximum rON flatness is critical |
Compared with TMUX1574RTER and ADG884BRMZ-REEL7, the ISL54062IRTZ-T uniquely combines sub-ohm rON, 6.5 V negative swing, and embedded click/pop suppression - making it the only option among the three qualified for direct AC-coupled audio switching without auxiliary components.

FAQ
What is the maximum negative signal swing supported by the ISL54062IRTZ-T?
The ISL54062IRTZ-T supports analog signals extending up to 6.5 V below the positive supply rail (V+). For example, with V+ = 5 V, the valid signal range is –1.5 V to +5 V. This capability enables direct interfacing with AC-coupled audio sources without external level-shifting circuitry, preserving signal integrity in battery-powered devices.
Does the ISL54062IRTZ-T require external components for click-and-pop elimination?
No, the ISL54062IRTZ-T integrates dedicated click-and-pop suppression circuitry that activates complementary shunt switches on NOx/NCx pins. When one path is closed, the other is actively discharged to GND through ~140 Ω, eliminating audible transients without external capacitors or resistors - a key differentiator versus generic analog switches.
Is the ISL54062IRTZ-T pin-compatible with other members of the ISL5406x family?
Yes, the ISL54062IRTZ-T shares identical pinout and footprint with ISL54062IRUZ-T (µTQFN) and ISL54062IRTZ (same TDFN, non-tape-and-reel). All variants use the same 10-lead TDFN package (L10.3x3A) and maintain identical electrical behavior, allowing drop-in replacement across packaging options without PCB redesign.
What is the guaranteed break-before-make time for the ISL54062IRTZ-T?
The ISL54062IRTZ-T guarantees a break-before-make time delay (tD) of ≤30 ns across the full operating temperature range (–40°C to +85°C) and supply voltages. This specification ensures no overlap between NCx and NOx conduction states, preventing short-circuits and signal corruption during switching transitions in sensitive audio or measurement paths.
Can the ISL54062IRTZ-T operate from a 1.8 V supply while maintaining audio-grade performance?
Yes, the ISL54062IRTZ-T is fully specified down to +1.8 V supply, delivering rON = 1.87 Ω (typ), tON = 145 ns, and THD+N = 0.04% at 32 Ω. While rON increases versus higher supplies, its 1.8 V logic compatibility and low 20 nA quiescent current make it ideal for ultra-low-power portable audio systems powered directly from single-cell Li-ion batteries.
