Product details
Overview
ISL84522IBZ from Intersil is a quad single-pole/single-throw (SPST) analog switch with four normally open (NO) channels, designed for precision signal routing in low-voltage systems. It operates from single +2V to +12V or dual ±2V to ±6V supplies, delivers 125Ω max RON at +5V, 60ns tON/20ns tOFF, and <1nA leakage at 85°C - enabling high-fidelity audio/video switching and portable medical instrumentation.
For engineers reviewing the ISL84522IBZ datasheet, ISL84522IBZ pinout, ISL84522IBZ application, or ISL84522IBZ equivalent, key selection criteria include verified RON flatness (≤12Ω), break-before-make timing (not applicable), CMOS/TTL compatibility, and SOIC-16 package compatibility with legacy DG412 and MAX4522 designs.
Technical Context
The ISL84522IBZ uses CMOS switch architecture with level-shifted gate drive to maintain consistent RON across supply voltages from ±2V to ±6V or +2V to +12V. Its digital control inputs are referenced to V+ and GND, independent of V−, ensuring stable logic thresholds (VINH ≥ 2.4V, VINL ≤ 0.8V) over V+ = 2.5V–10V.
Each NO channel exhibits matched RON (ΔRON ≤ 6Ω over temperature), low charge injection (≤5pC), and high OFF isolation (>90dB at 100kHz). The device achieves >400MHz small-signal bandwidth in 50Ω systems while maintaining <10nA max COM/NO/NC OFF leakage at 85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RON (max) | 125Ω at +5V supply - ensures minimal signal attenuation in audio and sensor front-end paths |
| tON/tOFF | 60ns / 20ns at +5V - supports high-speed multiplexing in test equipment and data acquisition |
| Leakage current | <10nA max at 85°C - preserves accuracy in high-impedance DAC/ADC interfaces |
| Analog range | 0V to V+ (single supply) - enables rail-to-rail signal handling without external biasing |
| Supply range | +2V to +12V or ±2V to ±6V - accommodates battery-powered and industrial dual-rail systems |
| ESD rating | >2000V per MIL-STD-883 Method 3015.7 - enhances robustness in handheld and field-deployable gear |
| Logic compatibility | TTL/CMOS - simplifies interface with microcontrollers and FPGAs without level-shifting |
Pinout & Package
ISL84522IBZ is housed in a 16-lead narrow-body SOIC (M16.15) package, 10.0mm × 4.0mm × 1.5mm, RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 (IN1–IN4) | Digital control input | Active-high logic controls NO closure; TTL/CMOS compatible with V+ referenced thresholds |
| 2, 6, 10, 14 (COM1–COM4) | Analog common terminal | Signal path hub per channel; connects to load or source depending on routing topology |
| 3, 7, 11, 15 (NO1–NO4) | Normally open analog output | Open-circuit when IN = 0; closed to COM when IN = 1 - enables safe default-off signal gating |
| 4 (V−) | Negative supply | Required for dual-supply operation; tied to GND for single-supply use |
| 8 (GND) | Ground reference | Return path for logic circuitry and level shifters; isolated from analog signal path |
| 16 (V+) | Positive supply | Primary power for analog switches and logic; sets analog voltage limits and RON performance |
| 12 (N.C.) | No internal connection | Unbonded pad - no electrical function; must remain unconnected |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPST NO configuration | Four independent, non-interacting analog paths - ideal for parallel channel selection in multichannel DAQ |
| RON matching (ΔRON) | ≤6Ω over full temperature range - minimizes gain error in precision amplifier switching networks |
| Low power consumption | <1μW typical - extends battery life in portable ECG monitors and handheld test tools |
| High OFF isolation | >90dB at 100kHz - prevents crosstalk between RF "Tee" switch paths in military radios |
| Charge injection | ≤5pC - reduces glitch-induced errors in sample-and-hold circuits and fast ADC front-ends |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4522ESE+ | Same 16-pin SOIC package; 130Ω RON max at +5V; 75ns tON; higher leakage (25nA max) | Suitable for general-purpose switching where tighter RON matching is not critical | Select MAX4522ESE+ only if legacy MAXIM footprint compatibility is required and 15ns slower tON is acceptable |
| DG412DN-E3 | SOIC-16; 100Ω RON max at ±15V; requires ±15V supply; no 3V operation support | Limited to industrial systems with bipolar high-voltage rails; incompatible with 3V/5V battery-powered designs | Choose DG412DN-E3 only for existing ±15V designs needing proven reliability - not for low-voltage portables |
Compared with MAX4522ESE+ and DG412DN-E3, the ISL84522IBZ uniquely supports true 2V–12V single-supply operation with sub-10nA leakage and 60ns switching, making it optimal for next-generation portable and medical electronics where supply flexibility and precision coexist.

FAQ
What is the maximum supply voltage rating for the ISL84522IBZ?
The ISL84522IBZ has an absolute maximum V+ to V− rating of 15V. It operates safely across a recommended supply range of +2V to +12V (single supply) or ±2V to ±6V (dual supply). Exceeding ±6V or +12V risks permanent damage, and proper supply sequencing - applying V+ and V− before digital/analog signals - is mandatory to avoid ESD diode conduction.
Does the ISL84522IBZ support 3V operation, and what are the key trade-offs?
Yes, the ISL84522IBZ supports +2.7V to +3.6V single-supply operation. At 3V, RON increases to 260Ω (typical), tON/tOFF degrade to 120ns/40ns, and bandwidth narrows - but leakage remains <10nA. This makes ISL84522IBZ viable for ultra-low-power portable devices where speed is secondary to battery life and signal fidelity.
How does the ISL84522IBZ differ from the ISL84521IBZ and ISL84523IBZ in functionality?
The ISL84522IBZ contains four normally open (NO) switches, whereas ISL84521IBZ has four normally closed (NC) switches, and ISL84523IBZ integrates two NO and two NC channels for dual SPDT or 2:1 mux use. All share identical RON, timing, and leakage specs, but their default states and truth tables differ - ISL84522IBZ is selected when fail-safe open-circuit behavior is required during power-down or logic low.
Is the ISL84522IBZ pin-compatible with industry-standard analog switches?
Yes, the ISL84522IBZ is pin-compatible with the DG412 and MAX4522 in 16-lead SOIC packages. Pin functions match directly: INx, COMx, NOx, V+, V−, GND, and N.C. positions align per datasheet top views. However, note that DG412 requires ±15V supplies, while ISL84522IBZ operates down to +2V - electrical compatibility requires verifying supply and signal voltage ranges.
What is the thermal resistance (θJA) of the ISL84522IBZ in its SOIC package?
The ISL84522IBZ in the 16-lead SOIC (M16.15) package has a typical junction-to-ambient thermal resistance (θJA) of 115°C/W under standard JEDEC test conditions. This value assumes mounting on a high-thermal-conductivity board in free air; actual θJA will improve with PCB copper area and airflow, supporting continuous operation up to +85°C ambient with <1μW power dissipation.
