Product details
Overview
ISL84052IAZ-T from Intersil is a dual 4-to-1 analog multiplexer/demultiplexer configured as two independent differential 4-channel switches, operating from single +2V to +12V or dual ±2V to ±6V supplies. It features 60Ω typical ON-resistance at ±5V, 90ns/60ns tON/tOFF at +5V, 5nA max off-leakage at +85°C, rail-to-rail signal handling, and an inhibit pin for simultaneous channel disable - used in high-speed analog signal routing for medical ultrasound front-ends and telecom infrastructure.
For engineers reviewing the ISL84052IAZ-T datasheet, ISL84052IAZ-T pinout, ISL84052IAZ-T application, or ISL84052IAZ-T equivalent, key selection criteria include dual 4:1 MUX topology, break-before-make switching, ±5V/5V supply flexibility, low charge injection (2pC), and compatibility with TTL/CMOS logic at 3.3V/5V systems.
Technical Context
The ISL84052IAZ-T implements two independent 4:1 multiplexer blocks (A and B), each controlled by shared ADDA/ADDB address inputs and a common INH inhibit line. Each block routes one of four NOx inputs to its COMx output, with internal CMOS transmission gates enabling bidirectional rail-to-rail analog signal flow.
It uses level-shifting circuitry to translate TTL/CMOS logic (0.8V/2.4V thresholds) into full-supply swing gate drive for the analog switches, supporting operation across the full ±2V to ±6V or +2V to +12V range while maintaining guaranteed timing and leakage specs over –40°C to +85°C.
Key Specifications

Pinout & Package
ISL84052IAZ-T is housed in a 16-lead QSOP package (Pb-free, RoHS compliant), with exposed pad not electrically connected. Pinout follows industry-standard analog MUX layout optimized for signal integrity and thermal dissipation in dense PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive power supply input | Drives internal logic and switch gate drivers; sets upper analog signal limit |
| V− | Negative power supply input | Required for dual-supply operation; connects to GND for single-supply use |
| GND | Ground reference | Reference for digital logic and level shifters; no analog signal path connection |
| INH | Inhibit control input | Active-high logic input that opens all switches simultaneously when driven to V+ |
| ADDA, ADDB | Address select inputs | Binary-encoded control lines selecting one of four NOx inputs per MUX bank |
| COMA, COMB | Common outputs | Analog outputs for MUX bank A (pin 13) and bank B (pin 3); bidirectional signal paths |
| NO0A–NO3A, NO0B–NO3B | Normally-open inputs | Eight analog inputs (four per bank); only one per bank conducts to COM when selected |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4052ACPP+ | Pin-compatible dual 4:1 MUX; 100Ω rON max at ±5V vs. ISL84052IAZ-T's 100Ω max; identical 90ns/60ns tON/tOFF at +5V | Same functional role in test equipment and portable instrumentation; MAX4052ACPP+ uses 16-pin DIP/SOIC, not QSOP | Select MAX4052ACPP+ for legacy through-hole or SOIC-based designs requiring drop-in replacement with identical timing and leakage specs |
| 74HC4052PW | Industry-standard CMOS dual 4:1 MUX; 120Ω rON typ at +4.5V; slower 200ns tON; no dual-supply support; higher 100nA leakage | Suitable for cost-sensitive consumer-grade signal routing where precision and low leakage are secondary | Choose 74HC4052PW only for non-critical, single-supply +5V applications where 120Ω rON and 100nA leakage are acceptable |
Compared with MAX4052ACPP+, ISL84052IAZ-T offers identical timing but lower typical rON (60Ω vs. 80Ω) and superior leakage (5nA vs. 10nA), making it preferred for high-accuracy medical and telecom front-ends; versus 74HC4052PW, ISL84052IAZ-T delivers 20× lower leakage and 2× faster switching, justifying its use in precision industrial DAQ.

FAQ
What supply voltage ranges does the ISL84052IAZ-T support?
The ISL84052IAZ-T operates from a single +2V to +12V supply or dual ±2V to ±6V supplies. At ±5V, it achieves 60Ω typical ON-resistance and 50ns/40ns tON/tOFF; at +5V (V− = GND), rON rises to 125Ω with 90ns/60ns timing. The device maintains guaranteed performance across –40°C to +85°C in both configurations, and its absolute maximum rating allows transient 15V supply tolerance.
Does the ISL84052IAZ-T support rail-to-rail analog signal operation?
Yes, the ISL84052IAZ-T supports true rail-to-rail analog signal operation - signals can swing from V− to V+ without clipping or distortion. This capability is maintained across its full supply range (+2V to +12V or ±2V to ±6V) and enables direct interfacing with op-amps, ADCs, and sensors operating at full supply rails, such as in portable medical devices and industrial DAQ systems using the ISL84052IAZ-T.
How does the INH pin function on the ISL84052IAZ-T?
The INH (inhibit) pin on the ISL84052IAZ-T is an active-high digital control input that simultaneously opens all analog switches when pulled to V+. When INH = GND, normal address-controlled switching occurs; when INH = V+, all eight NOx-to-COM paths are disabled regardless of ADDA/ADDB state. This feature enables fast system-level signal isolation, power sequencing control, and fault-safe shutdown - essential in safety-critical applications like MRI front-ends using the ISL84052IAZ-T.
What is the charge injection specification for the ISL84052IAZ-T, and why does it matter?
The ISL84052IAZ-T specifies 2pC typical charge injection, measured with CL = 1.0nF and RG = 0Ω. This low value minimizes voltage glitches on sampling capacitors during switching transitions, directly preserving accuracy in sample-and-hold circuits, switched-capacitor filters, and multiplexed ADC architectures. In applications like ultrasound beamforming or precision DAQ, this spec ensures sub-LSB error contribution even at high sampling rates - a key differentiator of the ISL84052IAZ-T over generic analog switches.
Is the ISL84052IAZ-T pin-compatible with industry-standard logic-family MUX ICs?
Yes, the ISL84052IAZ-T is pin-compatible with the 74HC4052 and MAX4582 in 16-lead SOIC, QSOP, and TSSOP packages. Its pinout matches the industry-standard dual 4:1 MUX layout: COMA/COMB on pins 13/3, NO0A–NO3A/NO0B–NO3B on pins 11/12/14/15 and 1/2/4/5, ADDA/ADDB on pins 11/10 (shared), and INH on pin 6. This allows direct substitution in existing designs without PCB changes, provided supply and timing requirements align - a documented advantage of the ISL84052IAZ-T.
