Product details
Overview
ISL84052IVZ from Intersil is a dual 4-to-1 analog multiplexer configured as two independent differential 4-channel MUXes, 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, 2pC charge injection, and an inhibit pin for simultaneous channel disable. It is used in high-speed signal routing for medical ultrasound front-ends and telecom line-card channel selection.
For engineers reviewing the ISL84052IVZ datasheet, ISL84052IVZ pinout, ISL84052IVZ application, or ISL84052IVZ equivalent, key selection criteria include dual 4:1 configuration with break-before-make switching, rail-to-rail analog signal handling, TTL/CMOS-compatible logic thresholds (0.8V/2.4V), low off-leakage (≤5nA @ +85°C), and TSSOP-16 packaging for space-constrained mixed-signal PCBs.
Technical Context
The ISL84052IVZ implements two fully independent 4:1 multiplexers (MUX A and MUX B), each with dedicated address inputs (ADDA/ADDB) and shared inhibit (INH). Each MUX selects one of four normally-open analog paths (NO0A–NO3A, NO0B–NO3B) to its common terminal (COMA/COMB), supporting bidirectional signal flow.
Its CMOS switch architecture uses level-shifted gate drive referenced to V+ and V−, enabling rail-to-rail analog operation and maintaining consistent timing and rON matching (<6Ω ΔrON) across channels under ±5V supply. Break-before-make timing is guaranteed at ≤30ns (full temperature range) to prevent signal shorting during channel transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Dual independent 4:1 analog multiplexer (not shared control logic) |
| ON-resistance (rON) | 60Ω typ @ ±5V - enables <1% gain error in 12-bit precision signal chains with 3kΩ load |
| Switching time (tON/tOFF) | 90ns/60ns max @ +5V - supports >5 MSPS multiplexed sampling in data acquisition systems |
| Charge injection | 2pC max - limits voltage glitch to <2mV on 1nF hold capacitors in sample-and-hold circuits |
| Off-leakage current | 5nA max @ +85°C, ±5V - ensures <1LSB error drift over 10s in high-impedance sensor interfaces |
| Analog signal range | Rail-to-rail (V− to V+) - preserves full dynamic range of ±5V op-amp outputs or 0–5V DACs |
| Logic compatibility | 0.8V/2.4V thresholds @ V+ = 3.3V/5V - interoperates directly with FPGA I/O banks without level shifters |
Pinout & Package
ISL84052IVZ is housed in a 16-lead TSSOP package (JEDEC MO-153, 4.4mm × 5.0mm, 0.65mm pitch), optimized for automated assembly and thermal performance (θJA = 110°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive power supply input | Drives internal CMOS switch gates and logic; sets upper analog rail (up to +12V) |
| V− | Negative power supply input | Drives internal CMOS switch gates; sets lower analog rail (down to −6V); tie 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: drives all switches OFF when pulled to V+; TTL/CMOS compatible |
| COMA / COMB | Common output terminals | Each serves as shared output node for its respective 4:1 MUX; bidirectional signal path |
| NO0A–NO3A / NO0B–NO3B | Normally-open analog inputs | Eight total inputs (four per MUX); only one connected to COMx per MUX at any time |
| ADDA / ADDB | Address select inputs | 2-bit binary control per MUX; determines which NOx connects to COMx (00→NO0, 11→NO3) |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 4:1 MUX architecture | Enables parallel channel selection (e.g., I/Q path routing) without inter-MUX timing coupling or shared address bus contention |
| Break-before-make switching | Guaranteed ≤30ns dead time prevents momentary shorting between analog sources during channel changes |
| rON matching & flatness | <6Ω channel-to-channel rON mismatch and <15Ω rON variation over full signal range preserve gain accuracy in programmable-gain amplifiers |
| Low charge injection (2pC) | Minimizes settling error in multiplexed ADC front-ends and integrator reset circuits |
| Pb-free RoHS-compliant TSSOP | Meets IPC/JEDEC J-STD-020 moisture sensitivity level (MSL3) for standard SMT reflow without baking |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4582ESE+ | Pin-compatible dual 4:1 MUX; 80Ω rON @ ±5V; 125ns/80ns tON/tOFF; no break-before-make guarantee | Suitable for lower-speed (<1 MSPS) industrial control where timing margin is less critical | Select MAX4582ESE+ if legacy design uses Maxim footprints and ±5V rON tolerance >20Ω is acceptable |
| TMUX1308PWR | Single 8:1 MUX (not dual 4:1); 4.5Ω rON @ 3.3V; 10ns/8ns tON/tOFF; requires external logic for dual-path emulation | Better for high-speed, low-rON single-path applications; not drop-in for dual independent routing | Choose TMUX1308PWR only when redesign permits consolidating both MUX functions into one device with added control logic |
Compared with MAX4582ESE+, ISL84052IVZ delivers tighter rON matching and guaranteed break-before-make-critical for precision medical signal chains. Versus TMUX1308PWR, ISL84052IVZ offers native dual-path independence but trades off speed and rON for architectural simplicity in multi-channel systems.

FAQ
What supply voltage ranges does the ISL84052IVZ support?
The ISL84052IVZ operates from a single +2V to +12V supply or dual ±2V to ±6V supplies. At +5V single supply, typical ON-resistance is 125Ω; at ±5V dual supply, it drops to 60Ω. The device maintains specified performance across the full −40°C to +85°C temperature range under these conditions, and absolute maximum ratings allow transient exposure up to ±15V on V+/V−.
How does the INH pin function in the ISL84052IVZ?
The INH (inhibit) pin on the ISL84052IVZ is an active-high digital control that simultaneously opens all analog paths in both MUXes when driven to V+. When pulled to GND, normal address-controlled switching resumes. Its TTL/CMOS-compatible thresholds (0.8V low, 2.4V high) allow direct interfacing with 3.3V or 5V microcontrollers without level translation, and it draws only ≤1µA quiescent current.
Can the ISL84052IVZ be used with 3.3V logic while powered from ±5V supplies?
Yes-the ISL84052IVZ supports mixed-voltage operation: digital inputs (INH, ADDA, ADDB) are referenced to V+ and GND, so 3.3V logic signals meet the 0.8V/2.4V thresholds even when V+ = +5V and V− = −5V. Internal level shifters translate these inputs to full ±5V gate drive for the analog switches, preserving 60Ω rON and 50ns/40ns switching times.
What is the significance of break-before-make timing in the ISL84052IVZ?
Break-before-make (BBM) ensures no overlap between the turn-OFF of the currently selected channel and turn-ON of the next, preventing momentary shorts between analog sources. The ISL84052IVZ guarantees ≤30ns BBM time across −40°C to +85°C, critical in applications like multiplexed sensor arrays or I/Q signal routing where source impedance mismatch could cause signal corruption or damage.
Does the ISL84052IVZ require external protection diodes for overvoltage on analog pins?
No-each analog pin (NOx, COMx) has integrated ESD protection diodes to V+ and V−. However, if analog signals may exceed V+ or fall below V−, external series resistors (for logic lines) or clamping diodes (for signal paths) are recommended per Intersil Application Note AN557. The ISL84052IVZ itself tolerates continuous analog voltages from (V− − 0.3V) to (V+ + 0.3V) without damage.
