Product details
Overview
ISL84052IVZ-T7A from Intersil is a dual 4-to-1 analog multiplexer switch configured as two independent differential 4-channel MUXes, operating from single +2V to +12V or dual ±2V to ±6V supplies. It delivers 60Ω ON-resistance at ±5V, 90ns/60ns tON/tOFF at +5V, and 5nA max off-leakage at +85°C, enabling high-fidelity signal routing in portable medical ultrasound front-ends and telecom ATE systems.
For engineers reviewing the ISL84052IVZ-T7A datasheet, ISL84052IVZ-T7A pinout, ISL84052IVZ-T7A application, or ISL84052IVZ-T7A equivalent, this device supports rail-to-rail analog signals, features break-before-make switching, TTL/CMOS-compatible logic thresholds (0.8V/2.4V), and an inhibit pin for simultaneous channel disable-critical for low-noise multiplexing in battery-powered instrumentation.
Technical Context
The ISL84052IVZ-T7A implements two independent CMOS analog switch arrays, each with four normally open (NO) inputs, one common (COM) output, and three address lines (ADDA, ADDB, INH) controlling channel selection. Its internal level shifters translate digital logic (referenced to V+ and GND) into full-rail analog gate drive across V+ and V−, supporting bipolar and single-supply operation without signal clipping.
Each MUX section exhibits matched ON-resistance (<6Ω ΔrON), low charge injection (2pC), and high off-isolation (>90dB at 100kHz), ensuring minimal crosstalk between channels and precise signal integrity during high-speed sampling in ADC/DAC interface circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Dual 4-to-1 multiplexer - two independent MUX sections sharing one inhibit pin |
| ON-resistance (rON) | 60Ω max at ±5V supply - enables low insertion loss in precision sensor signal chains |
| Switching time (tON/tOFF) | 90ns/60ns at +5V - supports >5 MHz multiplexed sampling in real-time data acquisition |
| Off-leakage current | 5nA max at +85°C with ±5V - preserves accuracy in high-impedance sample-and-hold circuits |
| Analog signal range | Rail-to-rail (V− to V+) - accommodates full-scale signals in ±5V op-amp stages or 0–5V DAC outputs |
| Digital input threshold | 0.8V low / 2.4V high - ensures reliable TTL/CMOS compatibility across +3.3V and +5V logic domains |
| Charge injection | 2pC - minimizes voltage glitch on integrator or capacitor-based measurement nodes |
Pinout & Package
ISL84052IVZ-T7A is housed in a 16-lead TSSOP package (Pb-free, RoHS compliant), optimized for space-constrained portable designs. Pin pitch is 0.65mm; body dimensions are 5.0mm × 4.4mm × 1.2mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive power supply input | Drives analog switch gates and internal logic; sets upper analog signal limit |
| V− | Negative power supply input | Drives analog switch gates; connect to GND for single-supply operation |
| GND | Ground reference | Reference for digital logic and level shifters; no connection to analog signal path |
| INH | Inhibit control input | Active-high logic: tie to V+ to open all switches simultaneously |
| ADDA, ADDB | Address select inputs | Binary-encoded channel selection (00–11) for each 4-to-1 MUX section |
| COMA, COMB | Common output terminals | Outputs of MUX-A (pin 13) and MUX-B (pin 3); each connects to one selected NOx pin |
| NO0A–NO3A, NO0B–NO3B | Normally open analog inputs | Eight total inputs (four per MUX); only one per section conducts when addressed |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Ensures no momentary short between channels during address transitions, preventing signal corruption in multi-sensor systems |
| rON matching <6Ω | Guarantees consistent gain and offset across channels in programmable gain amplifier networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4052ACPP+ | Same pinout, 16-pin PDIP; rON = 100Ω max at ±5V; tON/tOFF = 125ns/100ns; higher leakage (10nA) | Preferred for through-hole prototyping or legacy industrial controllers where TSSOP assembly is unavailable | Select MAX4052ACPP+ only if board layout allows DIP footprint and thermal budget permits higher rON-induced gain error |
| TMUX1308PWR | 8:1 single MUX (not dual 4:1); 16-pin TSSOP; rON = 4.5Ω at 3.3V; requires separate enable per channel; no inhibit pin | Suitable for space-constrained single-path routing but lacks simultaneous disable and dual-MUX parallelism | Choose TMUX1308PWR only when consolidating signal paths onto one MUX and accepting loss of independent section control |
Compared with MAX4052ACPP+, ISL84052IVZ-T7A offers 30% faster switching and half the leakage, making it superior for high-speed portable instrumentation; versus TMUX1308PWR, it provides true dual-MUX concurrency and system-level inhibit control-essential for synchronized multi-channel acquisition.

FAQ
What supply configurations does the ISL84052IVZ-T7A support?
The ISL84052IVZ-T7A operates from a single +2V to +12V supply (with V− tied to GND) or a dual ±2V to ±6V supply. At +5V single supply, rON is 125Ω max; at ±5V, it drops to 60Ω max. The device maintains rail-to-rail analog signal range and TTL/CMOS logic compatibility across both modes, making ISL84052IVZ-T7A adaptable to diverse power architectures without redesign.
How does the INH pin function in the ISL84052IVZ-T7A?
The INH (inhibit) pin on the ISL84052IVZ-T7A is an active-high digital control that simultaneously opens all analog switches in both MUX sections when driven to V+. When pulled to GND, normal address-controlled switching resumes. This feature enables global signal path disable-critical for safety-critical shutdown in medical devices or synchronization during system calibration sequences involving ISL84052IVZ-T7A.
What is the maximum analog signal bandwidth supported by the ISL84052IVZ-T7A?
The ISL84052IVZ-T7A maintains >90dB off-isolation and <-90dB crosstalk up to 100kHz, with usable bandwidth extending beyond 100MHz in 50Ω systems (per Figure 17). Its 90ns/60ns tON/tOFF at +5V supports multiplexing rates up to ~5MHz. For high-frequency applications, ISL84052IVZ-T7A delivers flat gain response and minimal phase distortion, validated in ultrasound and RF test environments.
Does the ISL84052IVZ-T7A require external level shifting for 3.3V logic control?
No. The ISL84052IVZ-T7A has TTL/CMOS-compatible digital inputs with 0.8V low and 2.4V high thresholds, fully functional with +3.3V logic driving ADDA, ADDB, and INH pins-even when powered from ±5V supplies. Internal level shifters translate these logic levels to full-rail analog gate voltages, eliminating external translators and simplifying interface design for ISL84052IVZ-T7A in mixed-voltage systems.
What is the thermal performance of the ISL84052IVZ-T7A in its TSSOP package?
The ISL84052IVZ-T7A in 16-lead TSSOP has a typical junction-to-ambient thermal resistance (θJA) of 110°C/W and junction-to-case (θJC) of 33°C/W. With max junction temperature rated at +150°C and operating ambient up to +85°C, it sustains full performance under continuous 10mA per channel load. Derating is recommended above 70°C ambient; ISL84052IVZ-T7A remains stable in handheld diagnostic tools and benchtop ATE fixtures without forced cooling.
