Product details
Overview
ISL8499IVZ from Intersil is a quad SPDT (dual DPDT) analog switch optimized for low-voltage, low-power portable systems. It operates from a single +1.65V to +4.5V supply, delivers 0.24Ω ON-resistance at 4.3V, achieves 15ns turn-on/13ns turn-off times, and supports 1.8V logic compatibility - enabling high-fidelity audio/video signal routing in space-constrained mobile phones and medical handhelds.
For engineers reviewing the ISL8499IVZ datasheet, ISL8499IVZ pinout, ISL8499IVZ application, or ISL8499IVZ equivalent, this page provides verified package mapping (16-lead TSSOP), confirmed rON matching (0.04Ω), guaranteed break-before-make timing (≥2ns), ESD robustness (9kV on COM pins), and real-world selection guidance against STG3699 and DG2799 alternatives.
Technical Context
The ISL8499IVZ implements four independent bidirectional SPDT switches configured as two DPDT sections, each controlled by one logic input (IN1–2 and IN3–4). Its CMOS architecture uses level-shifted digital inputs to drive analog switch gates, ensuring reliable operation across 1.65V–4.5V V+ while maintaining sub-0.5Ω rON flatness (0.05Ω) and <150nA leakage over temperature.
It guarantees break-before-make switching with ≥2ns delay, supports rail-to-rail analog signal range (0V to V+), and features integrated ESD protection (9kV HBM on COM pins, 4kV on all others). The device draws ≤12µA ICC at 4.2V supply with 2.85V logic inputs - critical for battery longevity in always-on sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.65V to +4.5V single supply - enables direct integration with Li-ion battery outputs and low-voltage ASIC I/O without level translation. |
| rON (4.3V) | 0.24Ω typical - minimizes insertion loss and THD (0.003%) in audio paths and precision signal chains. |
| tON/tOFF | 15ns/13ns at 4.3V - supports high-speed multiplexing in portable test equipment and fast-switching sensor front-ends. |
| rON Matching | 0.04Ω max - ensures channel-to-channel gain consistency in differential signal routing and dual-path calibration circuits. |
| Logic Compatibility | 1.8V CMOS-compatible inputs at 3V supply - eliminates need for external logic translators when interfacing with modern low-voltage microcontrollers. |
| ESD Rating (COM) | 9kV HBM - protects sensitive analog inputs in handheld devices exposed to frequent human handling and static discharge. |
| Leakage Current | ±150nA max (full temp range) - preserves accuracy in high-impedance sensor nodes and battery-monitoring circuits. |
Pinout & Package
ISL8499IVZ is packaged in a 16-lead Thin Shrink Small Outline Plastic (TSSOP) per JEDEC MO-153-AB, with 0.65mm pitch, 4.90mm × 6.25mm body, and exposed pad not connected internally (float or ground per layout).

|---|---|---|
| 1, 3, 4, 15, 16, 9, 13, 12, 11, 10, 2, 5, 7, 6, 8 | Switch Terminals (NO1–4, NC1–4, COM1–4) | Bidirectional analog signal paths; NO/NC pins define throw states; COM pins serve as common connection points for SPDT routing. |
| IN1–2, IN3–4 (Pins 14, 13, 12, 11) | Digital Control Inputs | Two logic inputs control two SPDT switches each; logic "0" ≤0.5V, logic "1" ≥1.4V at 3V supply - compatible with 1.8V CMOS drivers. |
| V+ (Pin 10) | Positive Supply Rail | Single power input for analog switches and internal level shifters; absolute max 4.7V - accommodates 4.3V ±10% supplies with noise margin. |
| GND (Pin 7) | Ground Reference | Common return for analog signals, digital logic, and ESD protection diodes - must be low-impedance to maintain rON flatness and THD performance. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low rON (0.24Ω @ 4.3V) | Reduces voltage drop and power loss in high-current analog paths - critical for battery-powered audio amplifiers and sensor signal conditioning. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STG3699 | Pin-compatible, identical pinout and function; same 0.24Ω rON at 4.3V but higher 25ns tON. | Targeted at STMicroelectronics-based designs; slightly slower switching limits use in >50MHz RF sampling paths. | Select STG3699 only if existing layout uses ST's footprint or qualification requires ST sourcing continuity. |
| DG2799 | Pin-compatible with ISL8499IVZ; 0.25Ω rON at 4.3V but higher 1.4µA ICC at 4.2V/2.85V logic. | Preferred in Vishay-qualified industrial systems; higher supply current reduces battery life in always-on portable devices. | Choose DG2799 when Vishay supply chain assurance or extended temperature validation (+105°C) is required. |
Compared with STG3699 and DG2799, the ISL8499IVZ offers the fastest switching (15ns/13ns), lowest quiescent current (≤12µA), and highest COM-pin ESD rating (9kV), making it optimal for next-generation battery-sensitive, high-fidelity portable electronics.

FAQ
What is the maximum supply voltage rating for the ISL8499IVZ?
The ISL8499IVZ has an absolute maximum V+ to GND rating of −0.3V to +4.7V. Operation up to +4.5V is specified, with 4.7V headroom accommodating 10% tolerance on 4.3V rails and transient overshoot. Exceeding +4.7V risks permanent damage to internal ESD diodes and CMOS structures.
Does the ISL8499IVZ support true bidirectional analog signal flow?
Yes, the ISL8499IVZ is fully bidirectional: analog signals pass equally well from COM to NO/NC or from NO/NC to COM. This is inherent to its CMOS transmission-gate architecture and confirmed by symmetric rON, leakage, and capacitance specs across all terminals - essential for shared-bus and loopback test applications.
How does the ISL8499IVZ achieve 1.8V logic compatibility with a 3V supply?
The ISL8499IVZ defines logic thresholds as VINL ≤0.5V and VINH ≥1.4V at 3V supply - aligning with 1.8V CMOS output specs (VOH ≥1.4V, VOL ≤0.5V). Its internal level shifter converts these inputs to full-rail gate drives, eliminating external translators and reducing system power and component count.
What is the thermal resistance (θJA) of the ISL8499IVZ in its TSSOP package?
The ISL8499IVZ in 16-lead TSSOP (M16.173) has a typical θJA of 150°C/W under JEDEC JESD51-2 conditions. This value assumes mounting on a standard FR-4 board with no copper pour; adding thermal vias to GND under the exposed pad can reduce θJA by ~30°C/W in production layouts.
Is the ISL8499IVZ pin-compatible with other variants in the ISL8499 family?
Yes, all ISL8499 variants - including ISL8499IR, ISL8499IV, ISL8499IRZ, and ISL8499IVZ - share identical 16-pin TSSOP and QFN footprints and pin functions. The IVZ suffix denotes Pb-free TSSOP packaging; electrical and timing specs are identical across all versions.
