Product details
Overview
ISL43410IUZ from Intersil is a low-voltage, single-supply, DPDT high-performance analog switch configured for bidirectional rail-to-rail signal routing in precision multiplexer and switching applications. It operates from +2V to +12V, delivers 115Ω ON-resistance at +5V, 60ns turn-on time, and features an inhibit pin for simultaneous channel disable. It is used in battery-powered medical ultrasound front-ends and portable communications equipment.
For engineers reviewing the ISL43410IUZ datasheet, ISL43410IUZ pinout, ISL43410IUZ application, or ISL43410IUZ equivalent, key selection criteria include supply voltage flexibility (2–12V), guaranteed break-before-make timing, low charge injection (≤0.5pC at 3V), and compatibility with TTL/CMOS logic across all supported supply rails.
Technical Context
The ISL43410IUZ implements a CMOS-based double-pole/double-throw (DPDT) switch architecture with integrated level shifters that translate digital control inputs (INH, ADD) into full-rail gate drive signals for analog pass transistors. Its internal logic ensures guaranteed break-before-make operation with ≤16ns delay across temperature.
It uses Si-gate CMOS process technology (193-transistor die) and relies on V+ and GND only-no dual or negative supplies. All analog pins feature ESD protection diodes to V+ and GND, requiring input signal clamping within those rails to avoid forward conduction and leakage increase.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | DPDT (2-pole × 2-throw); enables 2:1 multiplexing or signal path redundancy without external logic. |
| Supply Range | +2V to +12V single supply; supports Li-ion (3.3V), USB (5V), and industrial (12V) rails without level-shifting circuitry. |
| rON @ 5V | 115Ω typical; ensures minimal signal attenuation and gain error in precision ADC/DAC interface paths. |
| tON/tOFF @ 5V | 60ns / 30ns; enables high-speed channel switching in real-time sampling systems and ATE. |
| Charge Injection | 0.3pC typical (25°C, 5V); reduces settling error and droop in sample-and-hold and integrator reset circuits. |
| Off-Leakage Current | 5nA max at +85°C; preserves accuracy in high-impedance sensor interfaces and low-power standby modes. |
| Logic Compatibility | TTL/CMOS thresholds (0.8V/2.4V) validated from 3V to 11V supply; eliminates need for external translators with standard microcontrollers. |
Pinout & Package
ISL43410IUZ is packaged in a 10-lead MSOP (M10.118, JEDEC MO-187BA compliant), Pb-free, RoHS-compliant surface-mount package measuring 3.0mm × 3.0mm × 1.0mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 NO1 | Analog output (normally open, Pole 1) | Connects to COM1 only when ADD = 0; used for primary signal path selection in 2:1 mux configurations. |
| 2 COM1 | Analog common terminal (Pole 1) | Input/output node shared between NC1 and NO1; must be routed with controlled impedance for high-frequency integrity. |
| 3 NC1 | Analog output (normally closed, Pole 1) | Connected to COM1 when ADD = 0 is inactive; provides default path for fail-safe or biasing continuity. |
| 4 INH | Digital inhibit control input | Active-high; pulls all switches open when driven ≥2.4V; enables system-level power gating and fault isolation. |
| 5 GND | Analog/digital ground reference | Single ground plane required; decoupling capacitor (0.1µF) must be placed adjacent to Pin 5 for noise suppression. |
| 6 V+ | Positive supply input | Supplies both analog switch core and internal level shifters; requires local 1µF bulk + 0.1µF ceramic decoupling. |
| 7 COM2 | Analog common terminal (Pole 2) | Independent second pole; allows simultaneous switching of differential or dual-channel signals (e.g., stereo audio). |
| 8 NO2 | Analog output (normally open, Pole 2) | Complements COM2 under same ADD logic; maintains channel matching for balanced signal routing. |
| 9 NC2 | Analog output (normally closed, Pole 2) | Provides redundant or alternate path for COM2; matches NC1 timing and leakage for symmetrical design. |
| 10 ADD | Digital address select input | Controls NOx/NCx connection state (0 = NCx active, 1 = NOx active); compatible with 3.3V/5V GPIOs without pull-ups. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Ensures no signal shorting during pole transition; eliminates cross-conduction risk in sensitive measurement circuits. |
| rON matching <2Ω | Maintains amplitude consistency across channels in differential or multi-path signal conditioning networks. |
| Low charge injection (≤0.5pC) | Minimizes voltage step errors in sample-and-hold stages, enabling sub-12-bit accuracy without recalibration. |
| Single-supply +2V to +12V operation | Eliminates need for charge pumps or dual supplies in portable and industrial designs, reducing BOM count and layout area. |
| Pb-free MSOP package (M10.118) | Enables high-density placement in space-constrained handheld devices while meeting global environmental compliance requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4677EUA+ | 10-lead µMAX package; 125Ω rON @ 5V; no inhibit pin; 100ns tON; 10nA leakage at +85°C. | Lacks INH functionality; unsuitable for system-level fault shutdown; higher rON limits use in precision 12-bit DAC interfaces. | Select when board space permits µMAX footprint and inhibit control is handled externally. |
| ADG732BRUZ | 32-channel SPST; 4.5Ω rON @ 5V; 3.3V-only supply; no DPDT topology; requires external logic for pole pairing. | Not functionally equivalent: SPST architecture increases PCB routing complexity and component count for DPDT-equivalent behavior. | Choose only if high channel count and ultra-low rON outweigh topology mismatch and added control overhead. |
Compared with MAX4677EUA+ and ADG732BRUZ, the ISL43410IUZ uniquely integrates DPDT topology with inhibit control and wide supply range-enabling direct replacement in medical, telecom, and ATE designs where channel coordination, fault safety, and voltage flexibility are mandatory.

FAQ
What is the maximum allowable analog signal voltage range for the ISL43410IUZ?
The ISL43410IUZ supports rail-to-rail analog signals from 0V to V+, where V+ ranges from +2V to +12V. For example, with a +5V supply, the analog input/output range is 0V to +5V. Exceeding V+ or going below GND forward-biases internal ESD diodes and increases leakage-so signals must stay strictly within this window. This specification is confirmed in the Absolute Maximum Ratings and Electrical Specifications sections of the FN6044 datasheet.
Does the ISL43410IUZ require external pull-up or pull-down resistors on its digital control pins?
No, the ISL43410IUZ does not require external pull-up or pull-down resistors on INH or ADD pins. Its digital inputs have defined TTL/CMOS-compatible thresholds (0.8V low, 2.4V high at 5V supply) and draw only ±0.5µA input current. Driving these pins directly from microcontroller GPIOs-without resistors-is fully supported and recommended to minimize board area and ensure fast edge rates for optimal tON/tOFF performance.
Can the ISL43410IUZ operate reliably at +3V supply, and how does performance change versus +5V?
Yes, the ISL43410IUZ is fully specified at +3V supply. At +3V, rON increases to 190Ω (vs. 115Ω at +5V), tON rises to 144ns (vs. 60ns), and charge injection increases to 0.5pC (vs. 0.3pC). These shifts are documented in the +3V Electrical Specifications table (Page 4) and Typical Performance Curves (Figures 9–11, 15–16). The device remains functional and guaranteed across –40°C to +85°C at 3V.
What is the purpose of the INH (inhibit) pin on the ISL43410IUZ, and how should it be used?
The INH pin on the ISL43410IUZ is an active-high digital control that simultaneously opens all analog signal paths (COM1/COM2 disconnect from NO1/NC1 and NO2/NC2) regardless of ADD state. It should be tied to GND for normal operation and driven to V+ (≥2.4V) to force full channel disable-critical for system-level fault response, power sequencing, or safe startup/shutdown. This function is explicitly detailed in the Truth Table and Pin Descriptions (Page 2).
Is the ISL43410IUZ pin-compatible with other variants in the ISL43410 family, such as ISL43410IRZ?
No, the ISL43410IUZ (10-lead MSOP) is not pin-compatible with ISL43410IRZ (16-lead 3×3 QFN). Their pin counts, layouts, and terminal assignments differ significantly-e.g., ISL43410IRZ has three NC pins and separate exposed pad grounding, while ISL43410IUZ has no NC pins and uses all 10 leads for signal/control. Board redesign is required for substitution; this distinction is clearly shown in the Pinouts section (Page 2) and Ordering Information table (Page 2).
