Product details
Overview
ISL43640IUZ-T from Intersil is a low-voltage, single-supply 4:1 analog multiplexer switch with bidirectional rail-to-rail signal handling, 115Ω ON resistance at +5V, 60ns turn-on time, and 1nA off-leakage at 25°C - deployed in portable medical ultrasound front-ends and battery-powered data acquisition systems.
For engineers reviewing the ISL43640IUZ-T datasheet, ISL43640IUZ-T pinout, ISL43640IUZ-T application, or ISL43640IUZ-T equivalent, key selection criteria include supply voltage range (+2V to +12V), guaranteed break-before-make timing, RON matching (<2Ω), charge injection (≤1pC), and MSOP-10 package compatibility with high-density PCB layouts.
Technical Context
The ISL43640IUZ-T implements a CMOS-based 4-channel analog MUX architecture with integrated level shifters enabling TTL/CMOS logic compatibility across 3V–12V supplies. Its inhibit (INH) pin provides global channel disable, while address inputs (ADD1/ADD2) select one of four normally-open analog paths to the common (COM) terminal.
It uses Si-gate CMOS process with ESD diodes on all analog pins for overvoltage protection, supports rail-to-rail analog signals up to V+, and guarantees break-before-make switching to prevent signal shorting during channel transitions - critical for sample-and-hold and multiplexed ADC interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | 4:1 bidirectional analog multiplexer with single COM output |
| Supply Range | +2V to +12V single supply - enables direct interface with 3.3V/5V/12V systems without level translation |
| RON @ 5V | 115Ω typical - ensures minimal signal attenuation and gain error in precision sensor signal chains |
| tON/tOFF @ 5V | 60ns / 30ns - supports >10MHz multiplexed sampling in high-speed data acquisition |
| Charge Injection | ≤1pC - reduces settling error and droop in sample-and-hold circuits |
| Off-Leakage @ 25°C | 1nA max - preserves accuracy in high-impedance sensor and integrator applications |
| Logic Thresholds | 0.8V low / 2.4V high @ 5V - ensures robust noise margin with standard TTL/CMOS drivers |
Pinout & Package
ISL43640IUZ-T is packaged in a 10-lead MSOP (M10.118, JEDEC MO-187BA), 3mm × 3mm footprint with exposed pad option, optimized for thermal performance and board space efficiency in portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive power supply input | Supplies internal CMOS switches and level shifters; accepts +2V to +12V |
| GND | Ground reference | Return path for analog and digital circuitry; must be low-impedance for signal integrity |
| INH | Inhibit control input | Active-high global disable: drives all channels OFF when pulled to V+ |
| COM | Analog common terminal | Single bidirectional output node shared by all four switched paths |
| NO0–NO3 | Normally-open analog inputs | Four independent analog inputs; only one connected to COM per address state |
| ADD1/ADD2 | Binary address inputs | Selects active channel (00→NO0, 01→NO1, 10→NO2, 11→NO3) |
| N.C. | No internal connection | Unbonded pin; must be left floating or grounded per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Ensures no overlap between channel connections - prevents momentary shorts in multiplexed sensor arrays |
| RON matching <2Ω | Minimizes gain mismatch across channels in multi-sensor calibration systems |
| Low 1nA off-leakage | Maintains DC accuracy in high-Z medical electrode interfaces and pH sensor front-ends |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUA+ | 5V-only supply; 60Ω RON; 8-pin µMAX package; no INH pin | Lacks global inhibit and wider supply range - suitable only for fixed 5V systems | Choose when board space is constrained and supply is strictly 5V with no need for global disable |
| ADG1404BRUZ | ±15V dual supply or +12V single supply; 4.7Ω RON; 16-pin TSSOP; includes EN pin | Lower RON but higher quiescent current (120µA vs 0.1µA); requires tighter layout for high-voltage isolation | Prefer for ultra-low distortion audio or precision instrumentation where RON <5Ω is mandatory |
Compared with MAX4617EUA+ and ADG1404BRUZ, the ISL43640IUZ-T uniquely balances ultra-low leakage (1nA), wide supply flexibility (+2V to +12V), and integrated inhibit functionality - making it optimal for battery-operated, multi-voltage, and safety-critical analog routing.

FAQ
What is the maximum supply voltage rating for the ISL43640IUZ-T?
The ISL43640IUZ-T has an absolute maximum supply voltage of +15V, with recommended operating range from +2V to +12V. This 15V rating accommodates 10% tolerance on 12V rails and transient overshoot, ensuring robustness in industrial and telecom power environments without requiring external clamping.
Does the ISL43640IUZ-T support rail-to-rail analog signal operation?
Yes, the ISL43640IUZ-T supports true rail-to-rail analog signal operation - signals from GND to V+ pass unattenuated through the enabled channel. This capability is confirmed across all specified supply voltages (+2V to +12V) and is essential for interfacing with modern low-voltage sensors and ADCs.
What is the function of the INH pin on the ISL43640IUZ-T?
The INH (inhibit) pin on the ISL43640IUZ-T is an active-high global disable control. When driven to V+, it forces all four analog switches into the OFF state regardless of ADD1/ADD2 states - enabling fast system-level signal isolation in safety-critical or power-saving modes.
Is the ISL43640IUZ-T RoHS compliant and lead-free?
Yes, the ISL43640IUZ-T is RoHS compliant and features Pb-free plus anneal construction: 100% matte tin termination, Pb-free molding compound, and die attach materials - qualified per IPC/JEDEC J-STD-020 and rated MSL Level 1 for moisture sensitivity.
How does the ISL43640IUZ-T ensure break-before-make switching behavior?
The ISL43640IUZ-T guarantees break-before-make timing via internal logic design that enforces a minimum 5ns delay (typical 16ns) between turn-OFF of the currently selected channel and turn-ON of the newly addressed channel - verified across -40°C to +85°C and all supply voltages, preventing signal shorting during address transitions.
