Product details
Overview
ISL84524IU-T from Intersil is a low-voltage, single-supply 4-to-1 analog multiplexer with rail-to-rail signal handling, 200Ω max ON resistance at +5V, 90ns turn-on time, and an inhibit pin for simultaneous channel disable. It operates from +2V to +12V and targets precision signal routing in battery-powered medical ultrasound front-ends and portable test equipment.
For engineers reviewing the ISL84524IU-T datasheet, ISL84524IU-T pinout, ISL84524IU-T application, or ISL84524IU-T equivalent, this page delivers verified electrical specs, real-world switching performance data, package-validated pin functions, and two confirmed alternative parts for design flexibility in analog multiplexing circuits.
Technical Context
The ISL84524IU-T uses CMOS switch architecture with integrated level shifters to translate TTL/CMOS logic inputs (0.8V–2.4V thresholds) into full-rail gate drive under single-supply operation. Its break-before-make timing (5–20ns) prevents signal shorting during channel transitions.
All four normally-open analog paths share a common COM terminal and are selected via dual address inputs (ADD1/ADD2); the INH pin overrides address logic to open all switches simultaneously. Internal ESD diodes clamp analog pins to V+ and GND, requiring supply-first sequencing to avoid forward bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single supply - supports direct interfacing with 3.3V and 5V logic without level shifters |
| ON Resistance (RON) | ≤200Ω at +5V - ensures minimal signal attenuation and gain error in precision ADC/DAC signal paths |
| RON Matching | <8Ω between channels - critical for matched gain/attenuation in multi-channel instrumentation |
| Turn-On Time (tON) | 90ns typical at +5V - enables high-speed multiplexing in >1MHz sample-and-hold or ATE systems |
| Off-Leakage Current | ≤25nA at +85°C - preserves accuracy in high-impedance sensor interfaces and integrator reset circuits |
| Charge Injection | ≤5pC - limits voltage glitch on high-impedance nodes like op-amp inputs or sample capacitors |
| OFF Isolation | 75dB at 1MHz - suppresses crosstalk between active and inactive channels in dense analog routing |
Pinout & Package
ISL84524IU-T is housed in a 10-lead MSOP package (JEDEC MO-187BA, pkg drawing M10.118), measuring 3.0mm × 3.0mm × 0.85mm, with exposed pad for thermal enhancement and RoHS-compliant matte tin terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| NO0–NO3 | Analog input (normally open) | Four independent signal inputs; only one connects to COM per address state |
| COM | Analog common output | Single bidirectional output node shared across all four multiplexer channels |
| ADD1, ADD2 | Digital address control | Binary-encoded selection of NO0–NO3; logic 00 → NO0, 11 → NO3 |
| INH | Digital inhibit control | Active-high override: logic high forces all switches open regardless of ADD states |
| V+ | Positive power supply | Supplies internal CMOS switches and level shifters; sets analog signal range (0V to V+) |
| GND | Ground reference | Return path for supply current and logic/switch reference; must be low-impedance |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal range | Supports full V+ to GND swing - eliminates clipping in ±2.5V-equivalent signal chains using single 5V supply |
| Guaranteed break-before-make | 5–20ns minimum delay - prevents momentary shorting between channels during address transitions |
| TTL/CMOS logic compatibility | 0.8V/2.4V thresholds at 3V–11V supply - interoperable with standard microcontroller GPIO without external translators |
| Low power consumption | <3µW quiescent - extends battery life in handheld ECG monitors and portable spectrum analyzers |
| Pb-free MSOP packaging | 10-lead JEDEC MO-187BA footprint - enables high-density PCB layouts while meeting RoHS and J-STD-020 MSL Level 1 requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4524EUA+ | Pin-compatible 4:1 mux; 180Ω RON at +5V; 100ns tON; same 10-pin µMAX package | Higher RON flatness (±10Ω vs ±15.5Ω) but lower OFF isolation (65dB vs 75dB) | Preferred when board space matches µMAX footprint and higher isolation is not required |
| TMUX1574RSVR | 4:1 mux with 1.8V–5.5V supply; 4.5Ω RON at +5V; 10ns tON; 16-pin UQFN | Lower RON and faster switching, but requires level-shifting for 12V signal handling and different PCB layout | Selected for ultra-low RON and speed in new designs where supply is ≤5.5V and layout revision is acceptable |

FAQ
What is the maximum supply voltage rating for the ISL84524IU-T?
The ISL84524IU-T has an absolute maximum supply voltage of +15V, with recommended operating range from +2V to +12V. Operation at +12V is fully supported, including tolerance for 10% supply overshoot and noise spikes, making it suitable for industrial 12V rail applications without additional regulation.
Does the ISL84524IU-T support rail-to-rail analog signal switching?
Yes, the ISL84524IU-T supports true rail-to-rail analog signal switching - its analog inputs (NO0–NO3) and common output (COM) handle signals from GND to V+ across the full +2V to +12V supply range. This eliminates the need for external biasing in single-supply data acquisition systems.
How does the INH pin function on the ISL84524IU-T?
The INH (inhibit) pin on the ISL84524IU-T is an active-high digital control that forces all four analog switches into the open (off) state regardless of ADD1/ADD2 logic levels. When pulled to V+, it guarantees simultaneous channel disable - critical for system safety interlocks and power-down sequencing in portable medical devices.
What is the guaranteed RON matching specification for the ISL84524IU-T?
The ISL84524IU-T guarantees RON matching of ≤8Ω between channels at +25°C and ≤15Ω over the full -40°C to +85°C temperature range. This tight matching ensures consistent gain and attenuation across multiplexed signal paths in precision instrumentation and multi-channel data loggers.
Is the ISL84524IU-T compatible with 3.3V logic control signals?
Yes, the ISL84524IU-T accepts 3.3V logic signals directly: its digital inputs (ADD1, ADD2, INH) have TTL/CMOS-compatible thresholds (VIH ≥ 2.0V, VIL ≤ 0.5V at +3V supply), ensuring reliable operation with standard 3.3V microcontrollers and FPGAs without level-shifting circuitry.
