Product details
Overview
ISL43L410IUZ-T from Intersil is a bidirectional, double-pole/double-throw (DPDT) analog switch optimized for low-voltage, battery-powered systems. It operates from a single +1.65V to +3.6V supply, delivers 0.25Ω ON-resistance at 3V, achieves 12ns turn-on/5ns turn-off times, and features an inhibit pin for simultaneous signal path shutdown-enabling high-fidelity audio/video routing in space-constrained mobile phones and portable medical devices.
For engineers reviewing the ISL43L410IUZ-T datasheet, ISL43L410IUZ-T pinout, ISL43L410IUZ-T application, or ISL43L410IUZ-T equivalent, this page provides verified technical context, package-specific pin mapping, differential multiplexer design guidance, and validated alternative options for low-RON, sub-20ns switching in 1.8V logic-compatible systems.
Technical Context
The ISL43L410IUZ-T implements a committed DPDT topology with two normally open (NO) and two normally closed (NC) switch pairs per pole, guaranteeing break-before-make operation. Its sub-0.3Ω RON at 3V and 0.03Ω RON matching ensure minimal channel-to-channel gain error in differential 2:1 mux configurations.
Internal level shifters translate 1.8V CMOS logic inputs (VINH ≥ 1.4V, VINL ≤ 0.5V) into full-rail gate drive under single-supply conditions. ESD robustness (>9kV HBM) and <60nA max leakage support reliable operation in handheld equipment exposed to handling stress and variable ambient temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.65V to +3.6V single supply - enables direct integration with Li-ion battery rails and 1.8V/3.3V system logic without level translation. |
| ON Resistance (RON) | 0.25Ω typical at V+ = 3.0V - reduces insertion loss and thermal drift in precision analog signal paths. |
| RON Matching | 0.03Ω max between channels - maintains amplitude balance in differential or stereo signal routing. |
| Switching Speeds | tON = 12ns / tOFF = 5ns at V+ = 2.7V - supports high-speed data acquisition and RF front-end switching up to 120MHz bandwidth. |
| Logic Compatibility | 1.8V CMOS input thresholds (VINH ≥ 1.4V, VINL ≤ 0.5V at 3V supply) - eliminates need for external logic translators in modern low-voltage SoC interfaces. |
| ESD Rating | >9kV HBM - meets IEC 61000-4-2 Level 4 requirements for handheld consumer electronics without additional protection circuitry. |
| Leakage Current | <60nA max over temperature - preserves signal integrity in high-impedance sensor interfaces and battery-monitoring circuits. |
Pinout & Package
ISL43L410IUZ-T is packaged in a 10-lead MSOP (Mini Small Outline Plastic) with 0.5mm pitch, 3.0mm × 3.0mm body, and exposed thermal pad (M10.118 drawing). The package supports fine-pitch PCB layout and enhanced thermal dissipation (θJA = 190°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive power supply input | Supplies internal CMOS switches and level shifters; must be applied before analog signals to prevent ESD diode conduction. |
| GND | Ground reference | Return path for analog signal currents and digital logic; requires low-inductance connection to minimize ground bounce. |
| INH | Inhibit control input | Active-high logic pin: drives all switches open when high (≥1.4V), enabling system-level power gating of analog signal paths. |
| ADD | Address select input | Controls pole selection: ADD = 0 selects NC paths, ADD = 1 selects NO paths - defines DPDT switching state per pole. |
| COM1, COM2 | Analog common terminals | Input/output nodes shared across both throws; bidirectional operation allows signal flow in either direction with matched RON. |
| NO1, NO2 | Normally open switch outputs | Connect to COMx only when ADD = 1; used for default-off signal routing in fail-safe applications. |
| NC1, NC2 | Normally closed switch outputs | Connect to COMx only when ADD = 0; provides default-on path for bias or standby signal continuity. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RON flatness | 0.03Ω variation across full signal range - ensures linear gain response in audio line drivers and sensor signal chains. |
| Guaranteed break-before-make | Minimum 2ns delay between NC disconnect and NO connect - prevents momentary short-circuit in power-sensitive analog muxes. |
| Low charge injection | 95pC typical at 3V - minimizes voltage glitches on high-impedance nodes during switching, critical for precision ADC front-ends. |
| Pb-free RoHS compliance | Pb-free plus anneal process with 100% matte tin terminations - compatible with SnPb and Pb-free reflow profiles per IPC/JEDEC J-STD-020. |
| Low power consumption | <0.2µW quiescent power - extends battery life in always-on monitoring functions without compromising switching performance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMUX1574RTER | Higher RON (0.5Ω @ 3.3V), no inhibit pin, 12-bit precision grade | Targeted at precision data acquisition rather than high-speed portable muxing | Choose TMUX1574RTER when absolute linearity and low THD dominate over speed and system-level shutdown capability. |
| ADG732BRUZ | 32-channel SPST architecture (not DPDT), 4Ω RON, 1.8V logic compatible | Designed for large-scale channel expansion, not differential pair routing | Choose ADG732BRUZ when scalable single-pole switching is required across >8 channels, accepting higher RON and larger footprint. |
Compared with TMUX1574RTER and ADG732BRUZ, the ISL43L410IUZ-T uniquely combines DPDT topology, sub-0.3Ω RON, integrated inhibit control, and 12ns switching in a 3×3mm MSOP-making it optimal for compact, high-fidelity differential signal routing where channel count is fixed at two poles.

FAQ
What is the maximum supply voltage rating for the ISL43L410IUZ-T?
The ISL43L410IUZ-T has an absolute maximum V+ rating of 4.7V, with recommended operating range from +1.65V to +3.6V. Exceeding 4.7V risks permanent damage due to internal ESD diode forward conduction. Operation at 3.6V is fully characterized, and the 4.7V margin accommodates transient overshoot in battery-fed systems. Always apply V+ before analog signals to avoid latch-up.
Does the ISL43L410IUZ-T support true differential signaling in a 2-to-1 mux configuration?
Yes-the ISL43L410IUZ-T's committed DPDT structure with matched COM1/COM2, NO1/NO2, and NC1/NC2 pairs enables true differential 2:1 multiplexing. RON matching of 0.03Ω and flatness of 0.03Ω ensure balanced insertion loss and phase response across both legs, preserving common-mode rejection in ADC driver stages and audio codecs.
How does the INH pin function in the ISL43L410IUZ-T, and what logic levels activate it?
The INH pin is an active-high inhibit control: driving INH ≥1.4V (with V+ = 3V) opens all four switch paths simultaneously, regardless of ADD state. At V+ = 3V, logic "1" is defined as ≥1.4V and logic "0" as ≤0.5V. This feature enables system-level power gating-e.g., disabling audio paths during sleep mode without altering ADD control signals.
Can the ISL43L410IUZ-T operate reliably at 1.65V supply, and how do key parameters change?
Yes-the ISL43L410IUZ-T is fully specified down to 1.65V. At 1.8V supply, RON increases to 0.4Ω (typ), tON/tOFF degrade to 22ns/9ns, and logic thresholds shift to VINH ≥1.0V/VINL ≤0.4V. These trade-offs are documented in the 1.8V electrical specifications table and remain suitable for low-power IoT sensor hubs where speed is secondary to energy efficiency.
What package variants are available for the ISL43L410IUZ-T, and is the MSOP pinout identical to the DFN version?
The ISL43L410IUZ-T is the Pb-free, tape-and-reel variant of the 10-lead MSOP package (M10.118 drawing). While both MSOP and DFN versions share identical pin numbering and functional pinout (V+, NO1, COM1, ADD, NC1, NO2, COM2, INH, NC2, GND), their physical layouts differ: MSOP uses gull-wing leads; DFN uses bottom-exposed pads. PCB footprints are not interchangeable.
