Product details
Overview
ISL54064IRUZ-T from Intersil is a dual SPST analog switch with normally closed (NC) configuration, designed for low-distortion audio signal routing in portable battery-powered systems. It delivers 0.65 Ω typical ON-resistance at 4.3 V supply, supports negative signal swing down to 6.5 V below V+, and features integrated click-and-pop elimination circuitry for direct speaker interface in mobile phones and MP3 players.
For engineers reviewing the ISL54064IRUZ-T datasheet, ISL54064IRUZ-T pinout, ISL54064IRUZ-T application, or ISL54064IRUZ-T equivalent, key selection criteria include NC-switch topology, sub-ohm rON across 1.8–6.5 V supply range, guaranteed break-before-make timing, 1.8 V logic compatibility, and µTQFN-10 (1.8 × 1.4 mm) package suitability for space-constrained audio subsystems.
Technical Context
The ISL54064IRUZ-T implements two independent, bidirectional NC SPST switches using submicron CMOS process, with internal level shifters enabling 1.8 V logic control across full +1.8 V to +6.5 V supply range. Its negative signal swing capability (VCOM, VNC = V+ − 6.5 V to V+) enables ground-referenced AC-coupled audio paths without DC biasing.
Click-and-pop suppression is achieved via controlled turn-on/turn-off sequencing of internal gate drivers and charge injection minimization (≤200 pC), verified by THD+N ≤0.04% at 32 Ω load. Guaranteed break-before-make operation prevents momentary shorting during channel switching in multi-source audio routing.

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 |
|---|---|---|---|
| MAX4733EUA+ | NO configuration only; no integrated click/pop suppression; 0.9 Ω rON at 3 V | Suitable for generic signal routing but not speaker-level audio switching | Select when NC topology or audio-specific transient suppression is not required |
| TSM1014IDT | Single-channel; no negative swing support; 0.5 Ω rON at 5 V; SO-8 package | Larger footprint; limited to positive-only signal ranges (0 V to V+) | Choose for cost-sensitive industrial I/O where µTQFN size and bipolar swing are unnecessary |
Compared with MAX4733EUA+ and TSM1014IDT, the ISL54064IRUZ-T uniquely combines NC topology, −6.5 V negative swing, and integrated click/pop elimination in a 1.8 × 1.4 mm package-making it the only option for space-constrained, high-fidelity portable audio mute/switch functions requiring fail-safe default conduction.

FAQ
What is the default state of the switches in ISL54064IRUZ-T?
The ISL54064IRUZ-T contains two normally closed (NC) SPST switches. When IN1 and IN2 are at logic low (≤0.5 V), NC1 and NC2 conduct to COM1 and COM2 respectively. Applying logic high (≥1.4 V) opens both channels. This fail-safe behavior ensures audio continuity during microcontroller reset or power-up sequences - a critical feature for speaker and alarm applications where silent failure is unacceptable. The ISL54064IRUZ-T truth table explicitly defines this NC operation.
Does ISL54064IRUZ-T support true ground-referenced audio signals?
Yes. The ISL54064IRUZ-T supports analog signal voltages down to 6.5 V below V+, enabling true ground-referenced (or even negative) AC-coupled audio paths. For example, with V+ = 3.3 V, the valid signal range is −3.2 V to +3.3 V - sufficient to pass ±1 V audio without external DC bias. This eliminates coupling capacitors in headphone driver stages and reduces BOM count. The ISL54064IRUZ-T datasheet confirms this capability in Absolute Maximum Ratings and Figure 14.
How does the click-and-pop elimination circuitry in ISL54064IRUZ-T work?
The ISL54064IRUZ-T integrates dedicated gate-drive sequencing and charge-injection compensation circuitry that controls the turn-on/turn-off timing of internal MOSFETs to minimize voltage transients at COM/NC nodes. Measured charge injection is ≤200 pC, and waveforms in Figure 7A show suppressed step responses. This eliminates audible "pop" during speaker activation - a requirement validated in mobile phone audio testing. The ISL54064IRUZ-T implements this function without external components.
Can ISL54064IRUZ-T operate from a 1.8 V supply while maintaining audio performance?
Yes. The ISL54064IRUZ-T is fully specified down to +1.8 V supply, with rON = 1.87 Ω (typ), tON = 145 ns, and THD+N = 0.04% at 32 Ω. While rON increases versus higher supplies, it remains suitable for low-power headphone drivers and line-out buffering in wearables and hearing aids. The ISL54064IRUZ-T maintains 1.8 V logic compatibility and negative swing capability across the entire 1.8–6.5 V range per Electrical Specifications tables.
What is the thermal pad connection requirement for ISL54064IRUZ-T?
The exposed thermal pad on the underside of the ISL54064IRUZ-T µTQFN package must be soldered to a GND plane for optimal thermal dissipation and EMI suppression. Per datasheet Page 4, θJA = 155°C/W assumes proper pad connection; leaving it floating degrades junction temperature rise by >40°C under 100 mA load. The pad is internally connected to GND - no isolation or voltage biasing is permitted. This requirement applies specifically to the ISL54064IRUZ-T variant in the 1.8 × 1.4 mm package.
