Product details
Overview
ISL84582IVZ-T from Intersil is a low-voltage, bi-directional differential 4-to-1 analog multiplexer configured as two independent 4-channel switch arrays (A and B), operating from single +2V to +12V or dual ±2V to ±6V supplies. It features 39Ω ON-resistance at ±5V, 43ns tON/20ns tOFF at +5V, rail-to-rail signal handling, and an inhibit pin for simultaneous channel disable - used in high-speed medical ultrasound front-ends and portable ADC/DAC signal routing.
For engineers reviewing the ISL84582IVZ-T datasheet, ISL84582IVZ-T pinout, ISL84582IVZ-T application, or ISL84582IVZ-T equivalent, key selection criteria include guaranteed break-before-make timing, sub-2Ω rON matching across channels, <1pC charge injection at ±5V, off-leakage ≤0.2nA at +85°C, and TTL/CMOS logic compatibility across 3.3V/5V/±5V supply configurations.
Technical Context
The ISL84582IVZ-T implements a CMOS-based differential 4:1 mux architecture with separate COMA/COMB and A0–A3/B0–B3 signal paths, controlled by dual 2-bit address inputs (ADDA, ADDB) and a global INH pin. Its internal level shifters translate 0.8V/2.4V logic thresholds to full V+/V− gate drive voltages, enabling consistent switching performance across supply ranges.
It guarantees break-before-make operation (tBBM ≤9ns at +5V), supports rail-to-rail analog signals up to V+ or down to V−, and maintains <6Ω rON matching and ≤12pF COM ON capacitance - critical for maintaining gain accuracy in op-amp gain-switching networks and minimizing crosstalk in multi-channel data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Differential 4:1 multiplexer with dual independent switch banks (A and B) |
| Supply Range | +2V to +12V single or ±2V to ±6V dual - enables direct interface with 3.3V/5V/±5V systems without level shifters |
| rON @ ±5V | 44Ω typical - ensures minimal signal attenuation and distortion in precision analog routing |
| tON/tOFF @ +5V | 43ns/20ns - supports multiplexing of >10 MSPS sampled signals in portable test equipment |
| Charge Injection | 0.3pC typical at ±5V - reduces settling error in sample-and-hold circuits and integrator reset paths |
| Off-Leakage @ +85°C | 0.2nA max - preserves DC accuracy in high-impedance sensor interfaces and medical electrode amplifiers |
| Logic Thresholds | 0.8V low / 2.4V high - fully compatible with 3.3V and 5V TTL/CMOS controllers without external biasing |
Pinout & Package
ISL84582IVZ-T is housed in a 16-lead TSSOP package (JEDEC MO-153-AB compliant, 4.4mm × 5mm body, 0.65mm pitch) with exposed pad for thermal enhancement. Pin 1 is located at top-left corner when marking side faces up and notch/pin-1 indicator is left-aligned.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive power supply | Drives analog switch gates and internal logic; sets upper analog signal limit (VANALOG ≤ V+) |
| V− | Negative power supply | Required for dual-supply operation; connects to GND for single-supply mode; sets lower analog limit (VANALOG ≥ V−) |
| GND | Ground reference | Logic ground return only; no analog signal path connection - eliminates ground-loop coupling in mixed-signal systems |
| INH | Inhibit control input | Active-high digital enable; drives all switches OFF when high (≥2.4V), eliminating signal feedthrough during power sequencing |
| COMA / COMB | Common output terminals | Differential outputs for respective A and B mux banks; each handles rail-to-rail analog signals independently |
| A0–A3 / B0–B3 | Input signal terminals | Four differential input pairs per bank; matched layout minimizes skew and crosstalk between parallel channels |
| ADDA / ADDB | Address select inputs | 2-bit binary control for A and B banks respectively; synchronous switching ensures correlated channel selection |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | tBBM ≤9ns at +5V ensures no momentary short between selected channels - essential for avoiding transients in op-amp feedback networks |
| rON matching | <2Ω max ΔrON at ±5V maintains amplitude consistency across 4:1 signal paths in instrumentation-grade multiplexing |
| Low charge injection | 0.3pC typical at ±5V limits voltage glitch on hold capacitors - enables <16-bit linearity in precision sample-and-hold stages |
| Wide supply flexibility | Operates from +2V to +12V or ±2V to ±6V - supports battery-powered designs down to 2V and industrial 12V rails without external regulators |
| Pb-free RoHS compliance | 100% matte tin e3 termination - compatible with SnPb and Pb-free reflow profiles per IPC/JEDEC J-STD-020 MSL3 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Single-supply only (+2.7V to +12V); 60Ω rON @ +5V; no dual-bank differential architecture | Lacks independent A/B banks and differential COM outputs - unsuitable for true differential signal routing | Select when only single-ended 4:1 mux functionality is required and space constraints favor SOIC-16 over TSSOP-16 |
| ADG1404BRUZ | 4:1 single-ended mux; 4.7Ω rON @ ±15V but requires ±15V supplies; 10ns tON; no inhibit pin | Higher supply voltage requirement and absence of global INH limits use in low-voltage portable systems | Prefer for high-speed, low-rON applications where ±15V rails exist and channel disable must be managed per-switch |
Compared with MAX4617ESE+ and ADG1404BRUZ, the ISL84582IVZ-T uniquely delivers differential 4:1 switching with dual independent banks, guaranteed break-before-make, and full 2V–12V/±2V–±6V supply support - making it the only option among the three suitable for battery-powered differential signal acquisition with synchronized A/B path control.

FAQ
What supply voltage ranges does the ISL84582IVZ-T support?
The ISL84582IVZ-T operates from a single +2V to +12V supply or dual ±2V to ±6V supplies. At +5V, it delivers 44Ω typical ON-resistance and 43ns/20ns turn-on/turn-off times. The device maintains rail-to-rail analog signal handling across all supported supplies, with guaranteed break-before-make timing and TTL/CMOS-compatible logic thresholds (0.8V low, 2.4V high) verified from +2.7V to +10V.
How does the INH pin function on the ISL84582IVZ-T?
The INH (inhibit) pin on the ISL84582IVZ-T is an active-high digital control that simultaneously disables all analog switches when driven to V+ (≥2.4V). When INH = GND (≤0.8V), normal address-controlled switching resumes. This feature enables system-level power gating, prevents signal feedthrough during power-up/down sequences, and simplifies fault-safe design in medical and test equipment - all without requiring changes to address lines or external logic.
What is the maximum off-leakage current specification for the ISL84582IVZ-T at elevated temperature?
The ISL84582IVZ-T guarantees a maximum off-leakage current of 0.2nA at +85°C, measured on both NO/NC and COM terminals under ±5.5V supply conditions. This ultra-low leakage is critical for preserving DC accuracy in high-impedance sensor interfaces, such as thermocouple or pH electrode amplifiers, and ensures minimal baseline drift in precision sample-and-hold circuits over full industrial temperature range.
Does the ISL84582IVZ-T support differential signal routing, and how is it implemented?
Yes, the ISL84582IVZ-T implements true differential 4:1 multiplexing via two independent switch banks: Bank A (COMA, A0–A3) and Bank B (COMB, B0–B3). Each bank accepts four differential input pairs and routes them to its dedicated common output, enabling simultaneous, correlated selection of differential signal paths - a key capability for noise-rejecting front-ends in ultrasound and communications systems where common-mode rejection must be preserved.
What package type and footprint does the ISL84582IVZ-T use, and are there thermal considerations?
The ISL84582IVZ-T uses a 16-lead TSSOP package (JEDEC MO-153-AB, 4.4mm × 5mm, 0.65mm pitch) with exposed thermal pad. Its typical θJA is 150°C/W on a low-thermal-conductivity board in free air. For sustained operation near maximum junction temperature (+150°C), designers should ensure adequate PCB copper area under the exposed pad and consider airflow or localized heatsinking - especially when operating at 12V with continuous 30mA per channel.
