Product details
Overview
ISL84514IH-T from Intersil is a low-voltage, single-supply, normally open (NO) SPST analog switch optimized for battery-powered and space-constrained systems. It operates from +2.4V to +12V, delivers 8Ω rON at 12V, achieves 40ns tON/25ns tOFF, and consumes <5µW power - enabling precision signal routing in portable medical ultrasound front-ends and low-voltage ADC multiplexing.
For engineers reviewing the ISL84514IH-T datasheet, ISL84514IH-T pinout, ISL84514IH-T application, or ISL84514IH-T equivalent, this page provides verified specifications, SOIC-8 and SOT-23 package mapping, real-world leakage and switching performance across 3.3V/5V/12V rails, and validated alternatives for NO-SPST analog switching in portable instrumentation and data acquisition systems.
Technical Context
The ISL84514IH-T implements a CMOS transmission-gate architecture with integrated level shifters that translate TTL/CMOS logic inputs (0.8V/2.4V thresholds) into full-rail analog switch control signals across its 2.4V–12V supply range. Its substrate is tied to GND, and ESD protection diodes are present on all analog pins (COM, NO, IN) to V+ and GND.
It supports analog signal ranges from 0V to V+, exhibits rON flatness ≤5Ω over signal swing, and maintains >90dB off-isolation at 100kHz in 50Ω systems. Charge injection is limited to 10pC max, ensuring minimal settling error in sample-and-hold and integrator reset circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| rON (max) | 8Ω at V+ = 12V - enables low insertion loss in high-fidelity audio and sensor signal paths |
| tON/tOFF (max) | 40ns/25ns at V+ = 12V - supports ≥10MHz multiplexing in fast data converters |
| Leakage (off/on) | 20nA/40nA at +85°C - preserves accuracy in µA-level biomedical front-ends |
| Charge injection | 10pC max - minimizes voltage glitch in precision sample-and-hold stages |
| Supply range | +2.4V to +12V single supply - eliminates dual-rail complexity in portable designs |
| ESD rating | 2000V HBM - meets industrial handling requirements without external protection |
| Package | 5-lead SOT-23 - occupies 3.0mm × 1.7mm PCB area, ideal for handheld devices |
Pinout & Package
ISL84514IH-T is supplied in a Pb-free, RoHS-compliant 5-lead SOT-23 package (JEDEC MO-178AA, Intersil pkg code P5.064), with 0.95mm lead pitch and 1.3mm body height. Thermal resistance θJA is 225°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Digital control input | TTL/CMOS-compatible logic pin; 0.8V low / 2.4V high threshold across full supply range |
| 2 - NO | Analog switch output (normally open) | Open-circuit when IN = 0; connects to COM only when IN = 1 - no DC path in standby |
| 3 - GND | Ground reference | Substrate and logic ground return; must be connected before applying any signal or supply |
| 4 - COM | Analog switch common terminal | Input/output node shared between NO and internal transmission gate; supports bidirectional signal flow |
| 5 - V+ | Positive supply rail | +2.4V to +12V system power; sets analog signal range (0V to V+) and controls rON/speed |
Key Features
| Feature | Design Value |
|---|---|
| Drop-in replacement for MAX4514 | Pin- and function-compatible with MAXIM's industry-standard NO-SPST switch - simplifies legacy design upgrades |
| Ultra-low power consumption | <5µW quiescent dissipation - extends battery life in always-on portable meters and wearables |
| Low rON flatness | ≤5Ω variation over full analog signal swing - ensures consistent gain and linearity in amplifier networks |

Applications
| Battery-Powered Portable Meters | Ultrasound Front-End Signal Routing |
|---|---|
Use Scenario: Handheld multimeters and clamp meters requiring low-leakage, rail-to-rail analog switching under 3.3V operation. IC Role / Device Role / Timing Role: NO-SPST analog switch selecting between voltage, current, and resistance measurement paths. Use Value: 20nA max off-leakage at +85°C prevents measurement drift; 50Ω rON at 3.3V ensures sub-0.1% gain error in precision attenuators. |
Use Scenario: Beamforming ASIC interface where analog receive channels are dynamically routed to ADCs. IC Role / Device Role / Timing Role: High-speed, low-charge-injection switch enabling channel selection during echo windowing. Use Value: 10pC charge injection minimizes baseline shift in time-gain compensation circuits; 40ns tON supports ≥25MHz sampling rates. |
| +3V/+5V Data Converter Multiplexing | Audio/Video Source Selection |
Use Scenario: Input multiplexer for 12-bit SAR ADCs operating from 3.3V or 5V supplies in industrial PLC modules. IC Role / Device Role / Timing Role: Single-pole selector feeding analog inputs to successive-approximation core. Use Value: 12Ω rON at 5V yields <0.02% THD+N; rON flatness ≤3Ω maintains channel-to-channel matching across full input range. |
Use Scenario: Analog audio/video source switching in compact AV receivers and set-top boxes. IC Role / Device Role / Timing Role: Bidirectional SPST switch isolating unused inputs to prevent noise coupling and crosstalk. Use Value: >90dB off-isolation at 10kHz blocks audible-frequency interference; 14pF COFF limits bandwidth degradation in 20kHz audio paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NO-SPST analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4514EUT+T | Same 5-pin SOT-23 package; rON = 35Ω at 3.3V (vs. ISL84514IH-T's 50Ω); 15pC charge injection | Higher rON and charge injection limit use in ultra-low-distortion audio or high-resolution sampling | Select MAX4514EUT+T only if legacy MAXIM footprint compliance is mandatory and 35Ω rON suffices |
| TMUX1101DBVR | Lower 1.8V–5.5V supply range; 0.5Ω rON at 5V; but 100nA off-leakage at +85°C (5× higher) | Superior rON benefits low-voltage precision DAC buffers, but higher leakage disqualifies biomedical sensing | Prefer TMUX1101DBVR for 3.3V digital I/O expansion; retain ISL84514IH-T for µA-level leakage-critical analog paths |
Compared with MAX4514EUT+T and TMUX1101DBVR, ISL84514IH-T uniquely balances ultra-low leakage (20nA), moderate rON (8–50Ω across rails), and wide 2.4V–12V operation - making it the only choice for portable instruments requiring both battery longevity and analog integrity across multiple supply voltages.

FAQ
What is the maximum supply voltage rating for ISL84514IH-T?
The absolute maximum V+ rating for ISL84514IH-T is 15V, with recommended continuous operation up to +12V. Operation beyond 12V risks exceeding specified rON, leakage, and timing parameters - the device is fully characterized and guaranteed from +2.4V to +12V per FN6025 Rev 5.00.
Does ISL84514IH-T support bidirectional analog signal flow?
Yes, ISL84514IH-T supports fully bidirectional analog signal routing between COM and NO terminals. Its CMOS transmission-gate structure imposes no inherent directionality - voltage, current, or AC signals pass equally well in either direction when the switch is ON.
What is the typical rON value of ISL84514IH-T at 3.3V supply?
At V+ = 3.3V, ISL84514IH-T exhibits a typical rON of 50Ω (max 75Ω over temperature), measured with ICOM = 1.0mA and VCOM = 1.5V. This value is confirmed in the "Electrical Specifications – 3.3V Supply" table on page 5 of FN6025 Rev 5.00.
Can ISL84514IH-T be used with 12V logic-level control signals?
No - ISL84514IH-T's digital input (IN) is TTL/CMOS compatible with logic-high threshold of 2.4V minimum (up to V+), not 12V-tolerant. Applying 12V directly to IN exceeds absolute maximum rating. Use level-shifting or a series 1kΩ resistor to limit input current if driving from 12V logic.
Is ISL84514IH-T pin-compatible with the SOIC-8 version ISL84514IBZ-T?
No - ISL84514IH-T uses a 5-lead SOT-23 package with pinout {IN, NO, GND, COM, V+}, while ISL84514IBZ-T uses an 8-lead SOIC package with different pin assignment and two NC pins. They share identical electrical functionality but require separate PCB layouts and land patterns.
