Product details
Overview
ISL43210IH-T from Intersil is a low-voltage, single-supply, bidirectional SPDT analog switch optimized for battery-powered portable systems. It operates from +2.7V to +12V, delivers 19Ω ON-resistance at 5V, 28ns turn-on time, and 3nA max leakage - enabling precision signal routing in space-constrained ASIC-limited designs like cellular handsets and medical imaging front-ends.
For engineers reviewing the ISL43210IH-T datasheet, ISL43210IH-T pinout, ISL43210IH-T application, or ISL43210IH-T equivalent, this page provides verified electrical specs, SOT-23 package mapping, break-before-make timing validation, and two confirmed alternative parts for 2:1 analog multiplexing in 3.3V/5V/12V systems with <1Ω rON matching and sub-5pC charge injection.
Technical Context
The ISL43210IH-T uses CMOS transmission-gate architecture with integrated level-shifting logic to support TTL/CMOS-compatible control inputs across its full 2.7V–12V supply range. Its internal ESD diodes clamp analog pins to V+ and GND, requiring proper supply sequencing but enabling robust overvoltage tolerance up to ±0.3V beyond rails.
It implements guaranteed break-before-make switching with 10ns typical delay (tD) and achieves >76dB off-isolation at 1MHz. Bandwidth exceeds 300MHz in 50Ω systems, supported by low COM ON capacitance (28pF) and flat rON vs. voltage performance - critical for high-fidelity audio, ultrasound, and CT scanner signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2.7V to +12V single supply - supports direct integration into 3.3V, 5V, and 12V battery-powered systems without level shifters. |
| rON (5V) | 19Ω typical - enables low insertion loss in precision DAC/ADC interfaces and op-amp gain-switching networks. |
| tON/tOFF | 28ns / 20ns at 5V - ensures minimal propagation delay in high-speed multiplexing for test equipment and digital filters. |
| Charge Injection | 3pC typical - reduces voltage glitch in sample-and-hold circuits and integrator reset applications. |
| Leakage Current | 3nA max at 25°C - preserves signal integrity in low-current sensor front-ends and medical bio-potential monitoring. |
| Off Isolation | 76dB at 1MHz - suppresses crosstalk between channels in multi-signal medical imaging systems (e.g., PET, MRI). |
| ESD Rating | 2000V HBM - meets industrial handling requirements without external protection in handheld device PCB layouts. |
Pinout & Package
ISL43210IH-T is housed in a Pb-free, RoHS-compliant 6-lead SOT-23 package (JEDEC MO178AB, Intersil P6.064), measuring 2.80mm × 2.60mm × 1.30mm with 0.95mm lead pitch. The compact footprint supports high-density portable PCBs while maintaining thermal resistance θJA = 230°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Digital Control Input | TTL/CMOS-compatible logic input; 0.8V low / 2.4V high threshold ensures reliable switching across 3.3V–12V supplies. |
| V+ (Pin 2) | Positive Supply Rail | Single power input for analog switch core and internal level shifter; supports 2.7V–12V operation with 15V absolute max rating. |
| GND (Pin 3) | Ground Reference | Common return for analog signals and digital logic; must be established before applying input signals to avoid ESD diode conduction. |
| NC (Pin 4) | Normally Closed Analog Terminal | Connects to COM when IN = 0; maintains continuity during power-down if V+ remains active - used for default signal path selection. |
| COM (Pin 5) | Analog Common Terminal | Central bidirectional node; routes signal to NC (IN=0) or NO (IN=1); supports ±0.3V beyond rails via internal clamping diodes. |
| NO (Pin 6) | Normally Open Analog Terminal | Connects to COM only when IN = 1; isolated from COM at logic low - enables 2:1 multiplexer configuration with guaranteed break-before-make. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed Break-Before-Make | 10ns typical tD prevents signal shorting during state transitions - essential for protecting sensitive downstream circuitry in medical and test gear. |
| rON Matching | <1Ω between NC and NO paths at 5V - ensures matched gain and phase response in differential or dual-path signal conditioning. |
| Low Power Consumption | <5µW quiescent dissipation - extends battery life in always-on portable devices such as pagers and handheld radios. |
| Wide Supply Compatibility | Fully specified at 3.3V, 5V, and 12V with 10% tolerance - eliminates need for separate BOM variants across multiple platform voltages. |
| High-Frequency Performance | 300MHz bandwidth with flat gain response - supports video switching, ultrasound beamforming, and high-speed data acquisition. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUT+T | Higher rON (45Ω @ 5V), slower tON (65ns), same SOT-23-6 package and 2.7V–12V supply. | Lower bandwidth (100MHz) and higher charge injection (15pC) limit use in ultrasound or precision sample-and-hold. | Select when cost sensitivity outweighs speed/leakage requirements; verify layout compatibility with identical pinout. |
| ADG821BRMZ-REEL7 | Lower supply range (1.8V–5.5V), lower rON (0.5Ω @ 3V), but no 12V operation or 2kV ESD rating. | Not suitable for 12V industrial or medical systems requiring wide dynamic range or high-voltage signal routing. | Prefer for ultra-low-voltage portable designs where 12V compatibility and ESD robustness are not required. |
Compared with MAX4617EUT+T and ADG821BRMZ-REEL7, the ISL43210IH-T uniquely balances 12V operation, 28ns speed, 3nA leakage, and 2kV ESD in a standard SOT-23-6 - making it the only option validated for mixed-voltage medical imaging and ruggedized handheld communications equipment.

FAQ
What is the maximum supply voltage rating for the ISL43210IH-T?
The ISL43210IH-T has an absolute maximum V+ to GND rating of 15V, with recommended operating range from +2.7V to +12V. This 15V headroom accommodates 10% tolerance on 12V rails and transient noise spikes without damage - a key advantage over switches rated only to 13V.
Does the ISL43210IH-T support break-before-make switching, and is it guaranteed?
Yes, the ISL43210IH-T implements guaranteed break-before-make switching with a typical delay (tD) of 10ns. This is explicitly characterized and ensured across temperature (-40°C to +85°C) and supply voltage (2.7V–12V), preventing momentary shorting between NC and NO paths during transitions.
What is the typical charge injection value of the ISL43210IH-T, and why does it matter?
The ISL43210IH-T exhibits 3pC typical charge injection at 25°C. This low value minimizes voltage glitches on high-impedance nodes - critical in sample-and-hold circuits, integrator reset paths, and precision DAC output buffering where even nanovolt-level errors degrade measurement accuracy.
Can the ISL43210IH-T operate from a 3.3V supply, and how do key parameters change?
Yes, the ISL43210IH-T is fully specified at 3.3V: rON rises to 32Ω (typ), tON/tOFF increase to 40ns/20ns, and charge injection drops to 1pC. All digital thresholds (0.8V/2.4V) remain compatible, enabling seamless use across 3.3V, 5V, and 12V platforms without redesign.
Is the ISL43210IH-T RoHS compliant, and what packaging details apply?
Yes, the ISL43210IH-T is RoHS compliant and Pb-free, using 100% matte tin plate e3 termination finish. It is supplied in tape-and-reel format per P6.064 drawing, in a 6-lead SOT-23 package with JEDEC MO178AB and EIAJ SC-74 compliance - ensuring compatibility with standard automated assembly processes.
