Product details
Overview
ISL54059IRTZ-T from Intersil is a dual SPDT analog switch optimized for low-voltage, battery-powered audio/video signal routing. It operates from a single +1.8V to +6.5V supply, delivers sub-ohm ON-resistance (0.52Ω @ 4.5V), supports negative signal swing down to 6.5V below V+, and achieves fast switching (tON = 43ns @ 4.3V) in a 10-lead 3×3mm TDFN package.
For engineers reviewing the ISL54059IRTZ-T datasheet, ISL54059IRTZ-T pinout, ISL54059IRTZ-T application, or ISL54059IRTZ-T equivalent, key selection criteria include guaranteed break-before-make timing, rON matching ≤10mΩ, THD+N ≤0.02% at 32Ω, and compatibility with 1.8V logic control under +3V supply conditions.
Technical Context
The ISL54059IRTZ-T implements a committed dual SPDT architecture with independent IN1/IN2 digital controls, enabling precise dual 2-to-1 multiplexing. Its internal level shifters translate 1.8V-compatible logic inputs (VINH ≥1.4V, VINL ≤0.5V) into full-rail CMOS gate drive signals across the entire 1.8–6.5V supply range.
It features integrated ESD protection (>6kV HBM), negative-swing capability via specialized substrate biasing, and guaranteed break-before-make operation (tD ≤30ns) to prevent signal shorting during channel transitions - critical for audio path integrity and portable equipment reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +6.5V single supply - enables direct integration into Li-ion and multi-cell battery systems without level-shifting. |
| ON-Resistance (rON) | 0.52Ω @ V+ = 4.5V - ensures minimal insertion loss (<0.01dB) in 50Ω/32Ω audio paths. |
| rON Matching | ≤10mΩ between channels - maintains amplitude balance in stereo or differential signal routing. |
| Turn-On/Off Time | 43ns / 23ns @ V+ = 4.3V - supports high-speed data switching up to ~10MHz without edge distortion. |
| Negative Signal Swing | Up to 6.5V below V+ - allows rail-to-rail analog signal handling including AC-coupled audio with DC bias offsets. |
| THD+N | 0.02% @ 20Hz–20kHz, 32Ω load - preserves fidelity in portable media player headphone outputs. |
| ESD Rating | >6kV HBM - meets IEC 61000-4-2 Level 4 for handheld device front-end robustness. |
Pinout & Package
ISL54059IRTZ-T is packaged in a 10-lead 3×3mm Thin Dual Flat No-Lead (TDFN) with exposed thermal pad (PKG DWG L10.3x3A). Pin 1 is marked by a dot; pin 5 is GND and pin 10 is V+. The exposed paddle must be soldered to PCB ground for thermal and EMI performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2 | Digital control input | 1.8V logic-compatible; accepts 0.5V/1.4V thresholds up to +3V supply - eliminates need for external level shifters. |
| COM1, COM2 | Analog common terminal | Bi-directional signal path; supports ±300mA continuous current - suitable for line-level and headphone drive. |
| NO1, NO2 | Normally open analog switch terminal | Connects to COM when corresponding IN = logic high - forms one leg of 2:1 MUX per channel. |
| NC1, NC2 | Normally closed analog switch terminal | Connects to COM when corresponding IN = logic low - provides default signal path during power-up or fault. |
| V+ | Positive supply rail | +1.8V to +6.5V; requires local 0.1µF decoupling to GND - critical for stable rON and THD performance. |
| GND | Ground reference | Return path for analog and digital domains; tied to exposed thermal pad - reduces thermal resistance (θJA = 52°C/W). |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Prevents momentary shorting between NC and NO paths during switching - essential for avoiding audio pop/click in consumer devices. |
| rON flatness ≤0.33Ω | Ensures consistent gain and phase response across full analog signal range (e.g., –1.5V to +5V @ V+ = 5V). |
| Low charge injection (170pC) | Minimizes voltage glitch on high-impedance nodes (e.g., ADC inputs or filter capacitors) during switching. |
| OFF isolation ≥60dB @ 100kHz | Suppresses crosstalk between active and inactive channels - critical for multi-source audio routing. |
| 1.8V logic compatibility | Operates with standard 1.8V GPIO without pull-ups or translators - reduces BOM count in modern SoC-based designs. |

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 (0.8Ω @ 3.3V), no negative swing support, 1.2V logic compatible | Requires external level shifter for 1.8V control; unsuitable for signals extending below GND | Preferred where ultra-low leakage (<1nA) and smaller 1.6×1.6mm QFN are prioritized over negative swing |
| ADG732BRUZ-REEL7 | Higher rON (3.5Ω @ 3V), 16-channel, SPI interface, no break-before-make guarantee | Software-configurable but slower (tON = 12ns typical, but no BBM spec); larger 24-lead TSSOP | Selected when channel count >2 and serial control are required, accepting higher rON and layout footprint |
Compared with TMUX1574RTER and ADG732BRUZ-REEL7, the ISL54059IRTZ-T uniquely combines sub-ohm rON, guaranteed break-before-make, and 6.5V negative swing in a compact 3×3mm TDFN - making it optimal for high-fidelity, space-constrained portable audio routing where signal integrity and supply simplicity are critical.

FAQ
What is the maximum allowable analog signal voltage range for ISL54059IRTZ-T when operating at V+ = 5V?
When V+ = 5V, the ISL54059IRTZ-T supports an analog signal range from –1.5V to +5V - i.e., up to 6.5V below the positive supply rail. This negative swing capability enables direct interfacing with AC-coupled audio signals and sensor outputs requiring DC bias offsets, without external level-shifting circuitry.
Does ISL54059IRTZ-T require external decoupling capacitors, and if so, what value is recommended?
Yes, ISL54059IRTZ-T requires a 0.1µF ceramic capacitor placed as close as possible between the V+ and GND pins. This decoupling is essential to stabilize the internal CMOS switch biasing, minimize supply-induced rON variation, and suppress high-frequency noise that could degrade THD+N or switching transient behavior.
Is ISL54059IRTZ-T pin-compatible with other members of the ISL540xx family, such as ISL54058 or ISL54060?
No, ISL54059IRTZ-T is not pin-compatible with ISL54058 or ISL54060. While all three share the same 10-lead TDFN package outline, their pin functions differ significantly - e.g., ISL54058 uses different control logic mapping and lacks guaranteed break-before-make, and ISL54060 is a single SPDT variant with distinct pin assignments. PCB layout must be verified against the ISL54059-specific top-view diagram.
What is the guaranteed break-before-make time for ISL54059IRTZ-T, and why is it important in audio applications?
The ISL54059IRTZ-T guarantees break-before-make timing with tD ≤30ns across its full operating temperature range (–40°C to +85°C). This prevents momentary shorting between NC and NO paths during channel switching - eliminating audible pop/click artifacts in headphone and speaker outputs, which is critical for user experience in consumer audio devices.
Can ISL54059IRTZ-T operate reliably with a 1.8V logic control signal while powered from a 4.3V supply?
Yes, ISL54059IRTZ-T supports 1.8V logic-compatible inputs across its full supply range. With V+ = 4.3V, the specified VINH threshold is ≥1.6V and VINL is ≤0.5V - meaning a clean 1.8V GPIO output fully satisfies both conditions without translation, reducing system complexity and power consumption in SoC-based portable designs.
