Product details
Overview
ISL43110IH-T from Intersil is a low-voltage, single-supply, normally open (NO) SPST analog switch optimized for precision signal routing in battery-powered and high-speed systems. It operates from +2.4V to +12V, delivers 7Ω rON at 12V, 45ns tON at 5V, and 1nA max leakage - enabling use in portable medical ultrasound front-ends and low-voltage ADC multiplexing.
For engineers reviewing the ISL43110IH-T datasheet, ISL43110IH-T pinout, ISL43110IH-T application, or ISL43110IH-T equivalent, key selection criteria include its SOT-23-5 package footprint, TTL/CMOS-compatible control logic, 10pC max charge injection, and guaranteed performance across 3.3V/5V/12V supplies without level-shifting circuitry.
Technical Context
The ISL43110IH-T integrates CMOS transmission-gate architecture with on-chip level shifters that translate TTL/CMOS input logic (0.8V/2.4V thresholds) into full-rail analog gate drive, ensuring consistent switching across 2.4–12V supply range. Its substrate is tied to GND, and ESD protection diodes are placed between each analog pin and both V+ and GND.
Unlike bipolar-supply switches, it requires strict supply sequencing: V+ must be applied before any analog or digital signals to avoid forward-biasing internal clamping diodes. The device exhibits flat frequency response up to 20MHz in 50Ω systems and >200MHz -3dB bandwidth, with off-isolation exceeding 90dB at 100kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| rON (max) | 10Ω at 12V supply - enables minimal signal attenuation in precision sensor signal paths |
| rON flatness | 1.5Ω over signal range - ensures linear gain in programmable-gain amplifier networks |
| tON/tOFF (max) | 80ns/50ns at 5V - supports >10 MSPS multiplexed data acquisition |
| Charge injection | 10pC max - limits voltage glitch in sample-and-hold circuits to <1mV with 10nF hold capacitor |
| Off-leakage current | 10nA max at +85°C - preserves battery life in always-on portable monitoring devices |
| Supply range | +2.4V to +12V single supply - eliminates need for dual-rail generation in mixed-signal embedded systems |
| ESD rating | 2kV per MIL-STD-883 Method 3015 - meets industrial handling requirements without external protection |
Pinout & Package
ISL43110IH-T is housed in a Pb-free, RoHS-compliant 5-lead SOT-23 package (JEDEC MO-178AA, Intersil P5.064), measuring 2.80 × 2.90 × 1.30 mm. Its compact footprint supports high-density PCB layouts in space-constrained handheld instruments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Digital control input | TTL/CMOS-compatible logic pin; 0.8V/2.4V thresholds ensure direct interfacing with microcontrollers and FPGAs |
| 2 - NO | Analog switch output (normally open) | Open-circuit when IN = 0; connects to COM only when IN = 1 - ideal for enable-controlled signal paths |
| 3 - GND | Ground reference | Substrate and logic/analog ground return; must be low-impedance for leakage and noise control |
| 4 - COM | Analog switch common terminal | Signal source or sink node; supports bidirectional analog signal flow with rail-to-rail voltage range |
| 5 - V+ | Positive power supply | Single supply input (2.4–12V); powers internal logic, level shifters, and analog switch transistors |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUT+T | 5V-only operation; 35Ω rON (min 3.3V); no 12V spec; SOT-23-6 package | Suitable for fixed 3.3V/5V systems only; higher rON increases insertion loss in precision signal paths | Choose when supply is strictly ≤5V and cost sensitivity outweighs rON and leakage requirements |
| ADG801BRMZ-REEL7 | Single-supply 1.8–5.5V; 0.3Ω rON at 5V; 25pC charge injection; MSOP-8 package | Better rON and lower voltage operation, but larger footprint and higher charge injection than ISL43110IH-T | Prefer for ultra-low rON needs below 5V; avoid where 10pC charge injection is critical for sampling accuracy |
Compared with MAX4617EUT+T and ADG801BRMZ-REEL7, the ISL43110IH-T uniquely balances wide supply range (2.4–12V), sub-10Ω rON, and ultra-low 10pC charge injection in the smallest SOT-23-5 form factor - making it optimal for portable, multi-rail, precision-switching applications where board area and signal integrity are co-constrained.

FAQ
What is the maximum supply voltage rating for the ISL43110IH-T?
The ISL43110IH-T has an absolute maximum V+ to GND rating of 15V, with recommended operating range from +2.4V to +12V. Operation at 12V is fully characterized - including 7Ω rON, 37ns tON, and 1nA leakage - providing margin for 10% supply tolerance and transient spikes. Exceeding 15V risks permanent damage to internal ESD diodes and CMOS structures.
Does the ISL43110IH-T support rail-to-rail analog signal switching?
Yes, the ISL43110IH-T supports rail-to-rail analog signal switching: its analog signal range (VANALOG) is specified from 0V to V+, meaning signals from GND up to the positive supply rail can pass through the switch without clipping. This capability is validated at 3.3V, 5V, and 12V supplies and is essential for preserving dynamic range in sensor interfaces and DAC output stages.
What is the logic polarity relationship between IN and the switch state in the ISL43110IH-T?
The ISL43110IH-T is a normally open (NO) switch: when IN = 0 (≤0.8V), the switch is OFF (open between COM and NO); when IN = 1 (≥2.4V at 3.3V/5V, ≥4V at 12V), the switch turns ON (COM connected to NO). This true-level logic behavior is confirmed in the truth table on page 2 of FN6028 Rev 4.00 and applies across the full -40°C to +85°C temperature range.
Can the ISL43110IH-T be used with a 3.3V supply while driving 5V-tolerant logic inputs?
Yes - the ISL43110IH-T's digital input is TTL/CMOS compatible with VIH = 2.4V min at 3.3V supply, which aligns with standard 3.3V logic families (e.g., 74LVC, ARM GPIO). Its output does not drive logic; it controls an analog path. For interfacing with 5V logic, a series 1kΩ resistor on IN (per Figure 6) protects against overvoltage while maintaining sub-µA input current and negligible voltage drop during normal operation.
How does charge injection affect system performance when using the ISL43110IH-T in sample-and-hold circuits?
With 10pC max charge injection, the ISL43110IH-T introduces ≤1mV glitch on a 10nF hold capacitor - directly impacting 12-bit ADC accuracy (0.025% FS). This value is measured under worst-case conditions (CL = 1nF, RG = 0Ω) and remains stable across supply voltages. System-level mitigation includes using smaller hold capacitors or adding a reset switch with matched charge injection, as detailed in Figure 2 of FN6028.
