Product details
Overview
ISL5120IHZ-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 from +2.7V to +12V - enabling high-speed, low-leakage switching in space-constrained portable electronics.
For engineers reviewing the ISL5120IHZ-T datasheet, ISL5120IHZ-T pinout, ISL5120IHZ-T application, or ISL5120IHZ-T equivalent, key selection criteria include its 8-pin SOT-23 package, guaranteed rON matching ≤1Ω, 10nA max leakage, 5pC max charge injection, and TTL/CMOS-compatible digital control - all validated across -40°C to +85°C.
Technical Context
The ISL5120IHZ-T implements dual independent CMOS transmission gates with level-shifted digital inputs, enabling bidirectional analog signal flow between COM and NO pins. Its internal architecture ensures break-before-make is not required (unlike ISL5122/ISL5123), as both switches operate independently with no inter-channel timing dependency.
It uses Si-gate CMOS process technology with ESD diodes on all analog pins (NO, NC, COM) referenced to V+ and GND, supporting overvoltage protection up to ±0.3V beyond rails. Logic thresholds are fixed at VINL ≤0.8V and VINH ≥2.4V across 3.3V–12V supplies, ensuring compatibility with standard TTL and CMOS drivers without external biasing.
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, sensor, and DAC/ADC signal paths |
| rON Matching | ≤1Ω max - ensures matched gain/attenuation in differential or dual-path circuits |
| tON/tOFF | 28ns / 20ns at 5V - suitable for multiplexing signals up to ~15MHz fundamental frequency |
| Charge Injection | 5pC max - minimizes voltage glitch in sample-and-hold and integrator reset applications |
| Leakage Current | 10nA max at 25°C - preserves accuracy in high-impedance sensor front-ends and battery monitoring |
| ESD Rating | 2000V per MIL-STD-883 Method 3015.7 - provides robust handling in manual assembly and field environments |
Pinout & Package
ISL5120IHZ-T is housed in an 8-lead SOT-23 package (Pb-free, RoHS compliant, MSL Level 2), with pin 1 marked by a dot or beveled edge. Thermal resistance θJA = 215°C/W enables operation at full rated current without forced airflow in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN1) | Digital control input for Switch 1 | Active-high logic: drives NO1–COM1 path ON when ≥2.4V; TTL/CMOS compatible |
| 2 (NO1) | Normally open analog terminal, Channel 1 | Connects to COM1 only when IN1 = high; 8pF OFF capacitance minimizes crosstalk |
| 3 (GND) | Analog and digital ground reference | Must be low-impedance; shared return for all analog and logic currents |
| 4 (COM1) | Analog common node, Channel 1 | Bidirectional signal path between NO1 and COM1; supports rail-to-rail analog swing (0V to V+) |
| 5 (COM2) | Analog common node, Channel 2 | Independent of COM1; enables dual-path routing without interaction |
| 6 (NO2) | Normally open analog terminal, Channel 2 | Functionally identical to NO1; matched rON and timing ensure channel symmetry |
| 7 (V+) | Positive power supply | Supplies internal logic, level shifter, and switch transistors; absolute max = +15V |
| 8 (IN2) | Digital control input for Switch 2 | Independent of IN1; allows asynchronous control of second channel |
Key Features
| Feature | Design Value |
|---|---|

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 | Higher rON (45Ω @ 5V), slower tON (60ns), same 8-pin SOT-23 package | Less suitable for high-fidelity audio or fast multiplexing; better for cost-sensitive industrial controls | Select if budget priority outweighs speed/leakage requirements and 45Ω rON is acceptable |
| ADG702BRMZ-REEL | Lower leakage (1pA typ), but higher rON (60Ω @ 3V), different pinout (no IN1/IN2 separation) | Preferred for ultra-low-current sensor interfaces; incompatible pin-for-pin replacement | Choose when sub-nA leakage dominates design needs and PCB layout can accommodate pinout change |
Compared with MAX4617EUT+T and ADG702BRMZ-REEL, the ISL5120IHZ-T offers superior combination of speed (28ns), low rON (19Ω), and balanced leakage (10nA), making it optimal for portable, battery-powered systems requiring both precision and responsiveness.

FAQ
What is the maximum supply voltage rating for the ISL5120IHZ-T?
The ISL5120IHZ-T has an absolute maximum supply voltage of +15V, with recommended operating range from +2.7V to +12V. Operation at 12V is fully specified, delivering 11Ω rON and 25ns/17ns switching times. Exceeding +15V risks permanent damage due to internal ESD diode breakdown.
Does the ISL5120IHZ-T support rail-to-rail analog signal switching?
Yes, the ISL5120IHZ-T supports rail-to-rail analog signal switching: the analog signal range extends from 0V to V+, verified across all supply voltages (2.7V–12V). This allows full utilization of ADC/DAC dynamic range and eliminates need for external level-shifting circuitry.
Is the ISL5120IHZ-T pin-compatible with other devices in the ISL512x family?
Yes, the ISL5120IHZ-T shares identical 8-pin SOT-23 pinout with ISL5121IHZ-T and ISL5122IHZ-T, enabling drop-in substitution in dual SPST layouts. However, ISL5123IHZ-T uses a 6-pin SOT-23 and is not pin-compatible due to its SPDT configuration and reduced pin count.
What is the guaranteed rON matching specification for the ISL5120IHZ-T?
The ISL5120IHZ-T guarantees rON matching (ΔrON) of ≤1Ω across temperature (-40°C to +85°C) at 5V supply. This tight matching ensures consistent signal path resistance between the two independent NO switches, critical for differential signaling and dual-path calibration.
Can the ISL5120IHZ-T be used in 3.3V logic systems with 5V analog signals?
No - the ISL5120IHZ-T requires the analog signal voltage (on NO, COM pins) to remain within 0.3V of V+ and GND. With V+ = 3.3V, analog signals must stay within 0V–3.6V. To route 5V analog signals, V+ must be set to ≥5V, and logic inputs remain compatible via TTL thresholds (VINH ≥2.4V).
