Product details
Overview
ISL54063IRTZ-T from Intersil is a dual SPST analog switch with normally open (NO) configuration, designed for low-distortion audio signal routing in battery-powered portable systems. It delivers 0.55 Ω typical ON-resistance at +4.5V, supports negative signal swing down to 6.5V below V+, and features integrated click-and-pop elimination circuitry for direct speaker interface in MP3 players and mobile handsets.
For engineers reviewing the ISL54063IRTZ-T datasheet, ISL54063IRTZ-T pinout, ISL54063IRTZ-T application, or ISL54063IRTZ-T equivalent, key selection criteria include sub-ohm rON matching (≤30 mΩ), guaranteed break-before-make timing, 1.8V logic compatibility, and validated performance across 1.8V–6.5V single-supply operation with audio-grade THD+N (0.02% @ 32 Ω).
Technical Context
The ISL54063IRTZ-T implements a dual-channel, bidirectional CMOS analog switch architecture with independent digital control inputs (IN1/IN2) driving two normally open switches (NO1/NO2 ↔ COM1/COM2). Its internal level-shifter enables 1.8V logic compatibility across supply voltages up to +6.5V while maintaining rail-to-rail analog signal handling - including signals extending 6.5V below V+.
Click-and-pop suppression is achieved via controlled turn-on/turn-off sequencing of internal gate drivers and charge-injection minimization (≤200 pC), verified under 1.8V–4.3V supplies. The device guarantees break-before-make switching to prevent momentary shorting between channels during state transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON-resistance (rON) | 0.55 Ω typ @ V+ = +4.5V, 100 mA - ensures minimal insertion loss & voltage drop in audio paths |
| rON matching | ≤30 mΩ max - maintains channel-to-channel signal balance in stereo applications |
| Turn-on time (tON) | 43 ns typ @ V+ = +4.3V - enables fast switching without audible artifacts in dynamic audio routing |
| Negative signal swing | Up to 6.5V below V+ - supports AC-coupled audio signals with ground-referenced biasing |
| THD+N | 0.02% @ 20Hz–20kHz, 32 Ω load - meets high-fidelity audio requirements for portable playback |
| Supply range | +1.8V to +6.5V single supply - compatible with Li-ion, Li-poly, and regulated 3.3V/5V rails |
| Logic compatibility | 1.8V CMOS input thresholds (VINH ≥ 1.4V, VINL ≤ 0.5V @ 3V supply) - interfaces directly with baseband processors and PMICs |
Pinout & Package
ISL54063IRTZ-T is packaged in a 10-lead 3mm × 3mm TDFN (Pb-free, RoHS-compliant) with exposed thermal pad. Pin 1 is marked by a dot; the package requires GND connection to the underside paddle for optimal thermal performance and EMI suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive power supply | Single supply rail (+1.8V to +6.5V); must be decoupled with 0.1 µF capacitor near pin |
| GND | Ground reference | Return path for analog and digital circuits; connects to exposed paddle for thermal management |
| IN1, IN2 | Digital control inputs | Independent logic inputs controlling NO1/COM1 and NO2/COM2; 1.8V-compatible thresholds |
| NO1, NO2 | Normally open switch terminals | Open-circuit when INx = 0; connect to COMx only when INx = 1 (logic high) |
| COM1, COM2 | Analog common nodes | Signal I/O ports shared between NOx and NCx; support bidirectional signal flow |
| N.C. | No-connect terminal | Unbonded pin; must remain unconnected per datasheet (pin 4 and pin 9 in TDFN layout) |
Key Features
| Feature | Design Value |
|---|---|
| Audio click-and-pop elimination | Integrated circuitry suppresses transient noise during switching - eliminates need for external mute control in speaker paths |
| Sub-ohm rON flatness | 0.35 Ω max variation over full signal range - preserves linearity in high-fidelity audio and precision sensor multiplexing |
| Guaranteed break-before-make | Verified timing margin prevents channel shorting - critical for safe switching between multiple audio sources |
| Low leakage current | ≤0.7 µA max ICOM(ON) @ full temperature range - minimizes DC offset drift in sensitive analog front-ends |
| ESD robustness | >6 kV HBM rating - withstands handling and system-level ESD events without latch-up or parametric shift |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSM1022IDCNT | Higher rON (1.2 Ω typ @ 3.3V), no integrated click/pop suppression, 1.2V logic compatible | Lacks audio-optimized switching; suitable for general-purpose multiplexing but not speaker-level routing | Select when cost sensitivity outweighs audio quality; verify external mute circuitry required |
| MAX4677EUA+ | 0.8 Ω rON @ 5V, ±15V signal range, no negative swing below ground, 3.3V logic only | Designed for industrial signal conditioning, not portable audio; requires dual supply for full-range operation | Prefer for wide-voltage industrial muxing where ground-referenced negative swing is unnecessary |
Compared with TSM1022IDCNT and MAX4677EUA+, the ISL54063IRTZ-T uniquely combines sub-ohm rON, 6.5V negative swing, and embedded click/pop elimination - making it the only qualified option for space-constrained, battery-powered audio routing without external compensation.

FAQ
What is the maximum allowable analog signal voltage range for ISL54063IRTZ-T when operating at +3.3V supply?
At V+ = +3.3V, the ISL54063IRTZ-T supports an analog signal range from −3.2V to +3.3V (6.5V below V+ to V+). This is confirmed in the Absolute Maximum Ratings table and Figure 14 of the FN6582 datasheet. Operation outside this range risks forward-biasing internal ESD diodes and exceeding the ±300mA continuous current limit on COM/NO pins.
Does ISL54063IRTZ-T require external decoupling capacitors, and if so, what value is recommended?
Yes, ISL54063IRTZ-T requires a 0.1 µF ceramic capacitor placed as close as possible between V+ and GND pins. This is explicitly specified in the Pin Descriptions section (Page 3) and Detailed Description (Page 10) of the FN6582 datasheet to stabilize internal level shifters and suppress high-frequency noise that could degrade switching performance or increase THD+N.
Can ISL54063IRTZ-T be used in a normally closed (NC) configuration?
No - ISL54063IRTZ-T is a committed normally open (NO) dual SPST switch. Its internal topology connects NOx to COMx only when INx = logic high. For NC functionality, the pin-compatible ISL54064IRTZ-T must be used, as stated in the Product Overview (Page 1) and Truth Table (Page 3) of FN6582.
What is the guaranteed break-before-make interval for ISL54063IRTZ-T, and how is it implemented?
The ISL54063IRTZ-T guarantees break-before-make timing through internal gate-driver sequencing - verified in characterization but not specified as a minimum nanosecond value. Per the Detailed Description (Page 9), this architecture prevents simultaneous conduction between channels during logic transitions, eliminating risk of short-circuit current in multi-source audio routing.
Is ISL54063IRTZ-T compatible with 1.2V logic inputs?
No - ISL54063IRTZ-T requires minimum logic high input voltage (VINH) of 1.4V at 3V supply (Page 5), scaling to 1.0V at 1.8V supply (Page 7). A 1.2V logic high falls below the guaranteed recognition threshold across all operating conditions and may result in undefined switching behavior or increased supply current.
