Product details
Overview
ISL5120IH-T from Intersil is a low-voltage, single-supply, dual SPST analog switch with two normally open (NO) channels, designed for precision signal routing in battery-powered systems. It delivers 19Ω ON-resistance at 5V, 28ns turn-on time, <5µW power consumption, and operates across +2.7V to +12V supply range - enabling high-fidelity audio/video switching and portable instrumentation.
For engineers reviewing the ISL5120IH-T datasheet, ISL5120IH-T pinout, ISL5120IH-T application, or ISL5120IH-T equivalent, this page provides verified technical context, package-validated pin functions, real-world use-value metrics, and two confirmed alternative parts for design continuity in handheld, medical, and test equipment.
Technical Context
The ISL5120IH-T implements dual independent CMOS transmission gates with TTL/CMOS-compatible digital control inputs and rail-to-rail analog signal handling. Its internal level shifter ensures reliable switching across 3.3V, 5V, and 12V supplies without external biasing.
Each channel features matched 19Ω rON (5V), ≤1Ω rON matching between channels, 5pC max charge injection, and guaranteed break-before-make operation only in ISL5122/ISL5123 - not applicable to ISL5120IH-T, which uses NO/NO topology.
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 systems without level shifters |
| rON (5V) | 19Ω typical - enables low insertion loss in audio paths and minimal gain error in precision ADC/DAC interfaces |
| tON / tOFF | 28ns / 20ns at 5V - suitable for high-speed multiplexing up to ~15MHz analog bandwidth |
| Leakage Current | 10nA max at 25°C - preserves signal integrity in sample-and-hold and integrator reset circuits |
| Charge Injection | 5pC max - minimizes voltage glitch on high-impedance nodes like op-amp inputs or capacitor-based filters |
| Off Isolation | 76dB at 1MHz - suppresses crosstalk between active and inactive channels in multi-signal routing |
| ESD Rating | 2000V per MIL-STD-883 Method 3015.7 - withstands handling in standard assembly environments |
Pinout & Package
ISL5120IH-T is housed in an 8-lead SOT-23 package (Pb-free, RoHS compliant), with thermal resistance θJA = 215°C/W. Pin numbering follows standard SOT-23 top-view orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN1) | Digital control input for Switch 1 | TTL/CMOS-compatible; logic high ≥2.4V enables NO1 path; no internal pull-up/down |
| 2 (NO1) | Normally open analog terminal, Channel 1 | Connects to COM1 only when IN1 = high; 8pF OFF capacitance minimizes feedthrough |
| 3 (COM1) | Analog common node, Channel 1 | Bidirectional signal path; supports rail-to-rail analog voltages from GND to V+ |
| 4 (GND) | Ground reference | Return path for supply and logic; must be low-impedance to maintain leakage and noise specs |
| 5 (V+) | Positive supply input | Single power rail for analog and digital sections; absolute max 15V; powers internal level shifter |
| 6 (COM2) | Analog common node, Channel 2 | Independent of COM1; enables dual-channel signal routing without shared impedance |
| 7 (NO2) | Normally open analog terminal, Channel 2 | Connects to COM2 only when IN2 = high; identical rON and timing to NO1 |
| 8 (IN2) | Digital control input for Switch 2 | Independent logic control; allows asynchronous switching of two signal paths |
Key Features
| Feature | Design Value |
|---|---|
| Dual NO configuration | Enables parallel signal routing or redundant path selection without NC/NO interaction |
| 19Ω rON at 5V | Reduces signal attenuation in 50Ω–1kΩ audio and sensor interfaces; improves SNR vs higher-rON switches |
| 28ns tON / 20ns tOFF | Supports >10MSPS multiplexing in data acquisition systems with minimal aperture jitter |
| 5pC max charge injection | Prevents step errors in precision integrators and maintains DC accuracy in op-amp gain-switching networks |
| 10nA leakage (25°C) | Preserves long time-constant behavior in sample-and-hold circuits and low-power sensor front-ends |
| SOT-23 footprint | Minimizes PCB area in space-constrained portable designs; compatible with automated reflow (MSL Level 2) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUT+T | 8-pin SOT-23, 35Ω rON at 5V, 45ns tON, 100nA leakage (25°C), no 12V rating | Limited to 5.5V systems; higher rON increases insertion loss in audio paths | Choose for cost-sensitive 3.3V/5V-only designs where 19Ω rON is not required |
| ADG821BRMZ-REEL7 | 8-pin MSOP, 0.5Ω rON at 5V, 12ns tON, but 100pA leakage, 5.5V max supply | Superior rON and speed, but incompatible with 12V industrial rails and larger package | Choose for ultra-low-loss, high-speed 5V applications where board space permits MSOP |
Compared with MAX4617EUT+T and ADG821BRMZ-REEL7, the ISL5120IH-T uniquely balances 19Ω rON, 28ns speed, 12V operation, and SOT-23 size - making it optimal for portable equipment requiring wide supply flexibility and low power.

FAQ
What is the maximum supply voltage rating for the ISL5120IH-T?
The ISL5120IH-T has an absolute maximum supply voltage of 15V, with recommended operation from +2.7V to +12V. At 12V, its rON drops to 11Ω and switching times improve to 25ns/17ns, making it suitable for industrial 12V rails while maintaining robust overvoltage margin.
Does the ISL5120IH-T support break-before-make switching?
No. Break-before-make timing is guaranteed only for ISL5122 and ISL5123 variants. The ISL5120IH-T implements dual NO switches with independent control - meaning both channels can be turned on simultaneously, but no intentional dead-time is built in between transitions.
Can the ISL5120IH-T operate from a 3.3V supply?
Yes. The ISL5120IH-T is fully specified at 3.3V, delivering 32Ω rON, 40ns tON, and 20ns tOFF. Its TTL/CMOS-compatible inputs (VINH ≥2.4V, VINL ≤0.8V) interface directly with 3.3V logic without level shifting.
What is the thermal resistance of the ISL5120IH-T in its SOT-23 package?
The ISL5120IH-T in 8-lead SOT-23 has a typical junction-to-ambient thermal resistance (θJA) of 215°C/W. This value assumes mounting on a low-thermal-conductivity test board in free air; actual performance improves with PCB copper pour and airflow.
Is the ISL5120IH-T RoHS compliant and lead-free?
Yes. The ISL5120IH-T is Pb-free and RoHS compliant, using 100% matte tin (e3) termination finish. It meets IPC/JEDEC J-STD-020 reflow requirements and is rated MSL Level 2 for moisture sensitivity.
