Product details
Overview
ISL43210IHZ-T from Intersil is a low-voltage, single-supply, single-pole double-throw (SPDT) analog switch optimized for battery-powered portable equipment. It operates from +2.7V to +12V, delivers 19Ω ON-resistance at 5V, 28ns turn-on time, <1Ω rON matching, and 3nA max leakage - enabling precision signal routing in space-constrained ASIC-limited systems like cellular handsets and medical ultrasound front-ends.
For engineers reviewing the ISL43210IHZ-T datasheet, ISL43210IHZ-T pinout, ISL43210IHZ-T application, or ISL43210IHZ-T equivalent, this page provides verified electrical specs, SOT-23-6 pin mapping, real-world use cases in high-frequency multiplexing and low-leakage sample-and-hold circuits, and two validated alternative parts with documented functional and parametric differences.
Technical Context
The ISL43210IHZ-T implements a CMOS-based bidirectional SPDT switch with break-before-make timing (10ns typical), internal level-shifting logic compatible with TTL/CMOS inputs, and ESD protection diodes on all analog pins. Its architecture supports rail-to-rail analog signal switching up to V+ while maintaining sub-5µW quiescent power across the full supply range.
Switch performance is supply-voltage dependent: rON drops from 32Ω at 3.3V to 11Ω at 12V; tON/tOFF improve from 40ns/20ns to 25ns/17ns over the same range. Off-isolation remains ≥76dB at 1MHz, and crosstalk is –105dB at 12V, confirming suitability for high-fidelity analog signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.7V to +12V - enables direct integration into 3.3V, 5V, and 12V systems without level shifters |
| ON-Resistance (rON) | 19Ω typ @ 5V - ensures minimal signal attenuation and gain error in precision ADC/DAC interfaces |
| rON Matching | <1Ω max @ 5V - critical for matched-channel applications like differential signal routing or gain-switching networks |
| Turn-On/Off Time | 28ns / 20ns typ @ 5V - supports high-speed multiplexing up to ~15MHz without significant settling delay |
| Leakage Current | 3nA max @ 25°C - preserves accuracy in ultra-low-current sample-and-hold or integrator reset circuits |
| Charge Injection | 5pC max @ 12V - minimizes voltage glitch on high-impedance nodes during switching transitions |
| Off Isolation | 76dB @ 1MHz - suppresses crosstalk between active and inactive channels in multi-signal systems |
Pinout & Package
ISL43210IHZ-T is housed in a Pb-free, RoHS-compliant 6-lead SOT-23 package (JEDEC MO-178AB, Intersil P6.064), measuring 2.80 × 2.60 × 1.30 mm with 0.95 mm lead pitch. The compact footprint supports high-density PCB layouts in handheld and medical devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Digital control input | TTL/CMOS-compatible logic signal (0.8V low / 2.4V high) that selects NO or NC path; no external pull-up required |
| V+ (Pin 2) | Positive supply rail | Single power source for analog switch core and internal level shifter; supports 2.7–12V operation |
| GND (Pin 3) | Ground reference | Common return for supply, logic, and analog signals; must be connected before applying any input voltages |
| NC (Pin 4) | Normally closed analog terminal | Connected to COM when IN = 0; breaks before make occurs during state transition to prevent short-through |
| COM (Pin 5) | Analog common node | Input/output port shared by both switch paths; handles bidirectional signals within 0V to V+ range |
| NO (Pin 6) | Normally open analog terminal | Connected to COM when IN = 1; maintains >76dB isolation from COM when off |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make switching | 10ns minimum delay prevents momentary short between NC and NO paths during logic transitions |
| Low charge injection (5pC max) | Reduces voltage transient on high-Z nodes, enabling clean switching in integrator reset and sample-and-hold circuits |
| Wide supply compatibility (2.7–12V) | Eliminates need for separate bias rails in mixed-voltage systems - e.g., 3.3V MCU controlling 12V sensor interface |
| 2000V HBM ESD protection | Meets industrial handling requirements without external protection components on analog I/O lines |
| Sub-5µW quiescent power | Extends battery life in always-on portable instrumentation where standby current is critical |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUT+T | Higher rON (45Ω @ 5V), slower tON/tOFF (65ns/45ns), but lower charge injection (1.5pC) | Better suited for ultra-low-glitch sample-and-hold; less ideal for high-frequency multiplexing due to bandwidth limitation | Select MAX4617EUT+T when charge injection dominates design concern over speed or on-resistance |
| ADG849YKSZ-REEL7 | Lower rON (0.5Ω @ 5V), faster switching (12ns/8ns), but narrower supply range (1.8–5.5V) | Optimized for low-voltage portable systems only; incompatible with 12V sensor interfaces or industrial 5V backplanes | Select ADG849YKSZ-REEL7 for 3.3V/5V battery-powered designs requiring minimal rON and highest speed |
Compared with ISL43210IHZ-T, MAX4617EUT+T trades speed and on-resistance for lower charge injection, while ADG849YKSZ-REEL7 delivers superior rON and speed but sacrifices 12V compatibility - making ISL43210IHZ-T the balanced choice for wide-supply, medium-speed, low-leakage analog routing.

FAQ
What is the maximum analog signal voltage range supported by the ISL43210IHZ-T?
The ISL43210IHZ-T supports analog signals from 0V to V+, where V+ ranges from +2.7V to +12V. At 5V supply, the full analog range is 0–5V; at 12V supply, it extends to 0–12V. Exceeding V+ or going below GND forward-biases internal ESD diodes, so clamping or series resistors are recommended if overvoltage risk exists. This rail-to-rail capability makes ISL43210IHZ-T suitable for direct interfacing with sensors and DACs across multiple supply domains.
Does the ISL43210IHZ-T require external pull-up or pull-down resistors on its digital control input?
No, the ISL43210IHZ-T does not require external pull-up or pull-down resistors on the IN pin. Its digital input is TTL/CMOS compatible with guaranteed thresholds of ≤0.8V for logic low and ≥2.4V for logic high across the full 3.3V–12V supply range. Input current remains below ±1µA, so standard microcontroller GPIO outputs drive ISL43210IHZ-T directly without additional components - simplifying layout and reducing BOM count.
How does the ON-resistance of the ISL43210IHZ-T vary with supply voltage and signal voltage?
ISL43210IHZ-T rON decreases with higher supply voltage: 32Ω typ at 3.3V, 19Ω typ at 5V, and 11Ω typ at 12V. It also varies slightly with analog signal voltage - e.g., at 5V supply, rON is 19Ω at 3.5V signal but increases to ~23Ω near 0V or V+. This variation is characterized as rON flatness (≤8Ω max), ensuring consistent gain in amplifier networks and minimal distortion in audio paths when using ISL43210IHZ-T.
Is the ISL43210IHZ-T pin-compatible with other SOT-23-6 analog switches like the TS5A23157?
No, the ISL43210IHZ-T is not pin-compatible with the TS5A23157. While both use SOT-23-6 packages, their pinouts differ: ISL43210IHZ-T assigns IN to Pin 1, V+ to Pin 2, GND to Pin 3, NC to Pin 4, COM to Pin 5, and NO to Pin 6; TS5A23157 places GND at Pin 1 and IN at Pin 6. Swapping them without PCB revision would cause incorrect logic control and potential supply misconnection - always verify pin mapping before substitution.
What is the thermal resistance (θJA) of the ISL43210IHZ-T in its SOT-23-6 package?
The ISL43210IHZ-T has a typical junction-to-ambient thermal resistance (θJA) of 230°C/W when mounted on a low effective thermal conductivity test board in free air. This value assumes minimal copper pour and no thermal vias. In production PCBs with 1-in² 2-oz copper pad connected to Pin 2 (V+) and Pin 3 (GND), θJA can improve to ~120°C/W, allowing continuous operation at full 30mA current rating without exceeding the +150°C max junction temperature - critical for ISL43210IHZ-T reliability in sealed medical enclosures.
