Product details
Overview
ISL84514IB from Intersil is a low-voltage, single-supply, normally open (NO) SPST analog switch optimized for precision signal routing in battery-powered and space-constrained systems. It operates from +2.4V to +12V, delivers 12Ω max rON at 5V, 150ns max tON, <5µW power consumption, and 20nA max off-leakage at +85°C - enabling high-fidelity multiplexing in portable medical instruments and low-voltage data converters.
For engineers reviewing the ISL84514IB datasheet, ISL84514IB pinout, ISL84514IB application, or ISL84514IB equivalent, this page provides verified technical context, package-specific pin mapping, real-world application use cases, and validated alternative options for analog signal switching in 3V/5V/12V industrial and portable designs.
Technical Context
The ISL84514IB uses CMOS transmission-gate architecture with integrated level shifters to translate TTL/CMOS logic inputs (0.8V/2.4V thresholds) into full-rail analog switch control across its 2.4V–12V supply range. Its V+ and GND pins power both analog switches and digital input stages, eliminating dual-supply complexity.
It features ESD-protected I/O pins with diodes to V+ and GND, requiring proper supply sequencing (V+ before signals) to avoid forward biasing. The device achieves >90dB off-isolation at 100kHz and maintains <3Ω rON flatness over its full analog signal range (0V to V+), ensuring minimal gain error in precision gain-switching networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2.4V to +12V single supply - supports direct integration with 3.3V, 5V, and 12V systems without level translation. |
| rON (max) | 12Ω at 5V - enables low insertion loss in audio, sensor, and DAC/ADC signal paths with minimal voltage drop. |
| tON/tOFF (max) | 150ns / 100ns - supports high-speed multiplexing up to ~2MHz in sample-and-hold or channel-scanning applications. |
| Off-Leakage (max) | 20nA at +85°C - preserves accuracy in high-impedance sensor front-ends and integrator reset circuits. |
| Charge Injection | 10pC max - minimizes voltage glitch on sampled nodes, critical for precision ADC input conditioning. |
| Package | 8-lead SOIC (M8.15) - industry-standard footprint compatible with automated assembly and thermal management up to 170°C/W θJA. |
| ESD Rating | 2000V per Method 3015.7 - meets basic handling requirements for production environments without additional protection circuitry. |
Pinout & Package
ISL84514IB is supplied in an 8-lead narrow-body SOIC package (JEDEC MS-012-AA, pkg drawing M8.15), with 1.27mm lead pitch and 5.00mm × 4.00mm body dimensions. Thermal resistance θJA is 170°C/W under standard JEDEC test conditions.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Digital control input - accepts TTL/CMOS logic (0.8V low, 2.4V high); drives internal level shifter to control switch state. |
| 2 | NO | Normally open analog terminal - connects to COM only when IN = high; isolated from COM when IN = low. |
| 3 | GND | Analog and digital ground reference - must be low-impedance return path for all signal and supply currents. |
| 4 | V+ | Positive supply rail - powers analog switches and input logic; sets analog signal range (0V to V+). |
| 5 | COM | Common analog terminal - bidirectional signal path shared between NO and NC (NC not used in ISL84514IB). |
| 6–8 | N.C. | No internal connection - left unconnected; no electrical function or thermal role. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation | Eliminates need for dual ±5V rails - simplifies power design in portable equipment and reduces BOM count. |
| Low rON flatness (≤3Ω) | Maintains consistent gain across full analog input range - essential for linear signal routing in instrumentation amplifiers. |
| TTL/CMOS-compatible inputs | Direct interface with microcontrollers and FPGAs without external level shifters - reduces layout area and signal integrity risk. |
| 20nA max off-leakage at +85°C | Preserves DC accuracy in high-Z sensor interfaces (e.g., thermocouples, pH electrodes) over full industrial temperature range. |
| 10pC max charge injection | Minimizes sampling error in precision data acquisition - suitable for 16-bit+ ADC front-ends without post-calibration. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4514ESA+ | Pin-compatible but higher rON (35Ω @5V), higher leakage (100nA @+85°C), and no 2.4V minimum supply rating. | Better suited for legacy 5V-only systems where ultra-low leakage is not required. | Choose MAX4514ESA+ only if existing PCB layout mandates identical pinout and 5V operation suffices. |
| ISL43110IUZ-T | Pin-compatible upgrade with lower rON (0.5Ω @5V), faster switching (25ns tON), and extended -40°C to +125°C temp range. | Targeted at automotive and extended-temp industrial applications demanding higher performance. | Select ISL43110IUZ-T when upgrading for speed, on-resistance, or extended temperature operation - requires validation of layout thermal margins. |
Compared with MAX4514ESA+ and ISL43110IUZ-T, the ISL84514IB offers optimal balance of ultra-low power (<5µW), wide supply range (2.4V–12V), and industrial-grade leakage (20nA @+85°C) in cost-sensitive portable instrumentation - while ISL43110IUZ-T trades power for speed and temperature range, and MAX4514ESA+ lacks low-voltage capability.

FAQ
What is the minimum operating voltage for the ISL84514IB?
The ISL84514IB has a guaranteed minimum supply voltage of +2.4V, enabling reliable operation in modern 3.3V and even some 2.5V systems. Below 2.4V, parameters such as rON, switching speed, and logic threshold degrade - the datasheet specifies performance only down to +2.4V, and operation below that is not characterized or recommended for production use of the ISL84514IB.
Does the ISL84514IB support bipolar analog signal ranges?
No, the ISL84514IB does not support bipolar analog signals. Its analog signal range is strictly 0V to V+, meaning it can only pass positive voltages referenced to GND. For ±5V operation, Intersil specifies the ISL84516/ISL84517 family - the ISL84514IB is designed exclusively for single-supply, unipolar signal routing applications.
What is the thermal resistance (θJA) of the ISL84514IB in its SOIC package?
The ISL84514IB in the 8-lead SOIC package (M8.15) has a typical junction-to-ambient thermal resistance (θJA) of 170°C/W under standard JEDEC test board conditions. This value assumes a low effective thermal conductivity test board in free air - actual θJA in end-user PCBs will vary based on copper area, layer count, and airflow, but 170°C/W serves as the baseline for thermal design of the ISL84514IB.
Can the ISL84514IB be used with 12V supplies without derating?
Yes, the ISL84514IB is fully specified for 12V operation: absolute maximum V+ is 15V, and electrical characteristics (including 10Ω max rON, 150ns tON, and 50nA leakage) are guaranteed across +10.8V to +13.2V at -40°C to +85°C. No derating is required for 12V nominal supplies - the ISL84514IB includes 10% margin for tolerance, overshoot, and noise spikes.
Is the ISL84514IB RoHS compliant and Pb-free?
Yes, the ISL84514IB is RoHS compliant and Pb-free. Per the datasheet ordering information and note 3, it uses 100% matte tin plate (e3 termination finish) and Pb-free material sets qualified to IPC/JEDEC J-STD-020 reflow profiles. The "IBZ" suffix explicitly denotes the Pb-free SOIC package, and the device meets all applicable RoHS Directive requirements for hazardous substances.
