Product details
Overview
ISL54500IRUZ-T from Intersil is a single-pole/double-throw (SPDT) analog switch optimized for battery-powered portable systems, featuring 5.0 Ω ON-resistance at +5.0V supply, 22 ns turn-on time, and guaranteed break-before-make switching. It operates from +1.8V to +5.5V, supports 1.8V CMOS logic compatibility at +3V supply, and delivers low distortion in audio/video signal routing applications.
For engineers reviewing the ISL54500IRUZ-T datasheet, ISL54500IRUZ-T pinout, ISL54500IRUZ-T application, or ISL54500IRUZ-T equivalent, key selection criteria include supply-voltage-dependent rON matching (≤0.3 Ω), sub-100 nA leakage across -40°C to +85°C, and µTDFN package footprint constraints for space-constrained handheld designs.
Technical Context
The ISL54500IRUZ-T implements a committed SPDT architecture with one normally open (NO) and one normally closed (NC) channel, enabling use as a 2:1 multiplexer. Its internal level shifter converts 1.8V CMOS-compatible digital inputs into full-rail analog gate drive signals across the entire 1.8V–5.5V supply range.
Break-before-make timing (tD ≤ 42 ns at 1.8V) is guaranteed by design, preventing signal shorting during state transitions. ESD robustness is ensured via integrated 6 kV HBM protection diodes on all analog and digital pins, with clamping behavior explicitly defined for overvoltage events exceeding V+ or GND.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V - enables direct interface with Li-ion battery rails and 3.3V/5V system supplies without level shifting |
| ON-Resistance (rON) | 5.0 Ω at +5.0V - ensures minimal insertion loss (<0.05 dB) in 50Ω RF/audio paths |
| rON Matching | ≤0.3 Ω max over temperature - critical for balanced differential signal switching and THD-sensitive audio routing |
| Switching Speed | tON = 22 ns / tOFF = 15 ns at +4.5V - supports high-speed data multiplexing up to 350 MHz -3dB bandwidth |
| Analog Signal Range | 0V to V+ - allows rail-to-rail signal handling without external biasing networks |
| Leakage Current | ±300 nA max over -40°C to +85°C - preserves signal integrity in high-impedance sensor or medical front-end circuits |
| ESD Rating | 6 kV HBM - meets IEC 61000-4-2 Level 4 system-level ESD immunity requirements |
Pinout & Package
ISL54500IRUZ-T is packaged in a 6-lead ultra-thin dual flat no-lead (µTDFN) measuring 1.2 mm × 1.0 mm × 0.4 mm, with 0.4 mm pitch and exposed thermal pad. This RoHS-compliant, Pb-free package supports reflow soldering per IPC/JEDEC J-STD-020 MSL3 classification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NO (Normally Open) | Analog output path active only when IN = HIGH; used for primary signal routing in mux configurations |
| 2 | GND | Reference ground for analog signal paths and digital logic; must be low-impedance connection to minimize noise coupling |
| 3 | NC (Normally Closed) | Analog output path active only when IN = LOW; provides fail-safe default signal path in power-loss scenarios |
| 4 | COM | Common analog input/output node; bidirectional operation supports signal routing in either direction |
| 5 | V+ | Single positive supply rail (1.8V–5.5V); powers internal CMOS switches and level shifters; requires local 0.1 μF decoupling |
| 6 | IN | 1.8V CMOS-compatible digital control input; logic HIGH ≥1.4V at +3V supply; drives internal switch gate directly |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed Break-Before-Make | Prevents momentary short-circuit between NO and NC paths during switching; tD ≥18 ns ensures safe signal handover |
| rON Flatness | 1.5 Ω max over full analog range at +4.5V - maintains consistent gain and linearity across 0V–V+ signal swing |
| Low Charge Injection | 16 pC typical - minimizes voltage glitches on high-impedance nodes (e.g., SAR ADC sample capacitors) |
| OFF-Isolation | 75 dB at 1 MHz - suppresses crosstalk between active and inactive channels in multi-signal routing |
| 1.8V Logic Compatibility | Valid VINH ≥1.4V and VINL ≤0.5V at +3V supply - eliminates need for external logic translators in low-voltage ASIC interfaces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL54050IRUZ-T | Lower rON (3.5 Ω @ 5V), higher supply current (1.5 µA), same µTDFN-6 package | Better performance in low-distortion audio but higher static power draw | Preferred when THD <0.01% and rON matching <0.1 Ω are required at expense of quiescent current |
| TMUX1574RTER | Higher rON (7.5 Ω @ 5V), wider temp range (-55°C to +125°C), different pinout (SOT-23-6) | Supports extended industrial environments but incompatible PCB layout | Selected for harsh-environment deployments where ISL54500IRUZ-T's -40°C to +85°C rating is insufficient |
Compared with ISL54500IRUZ-T, ISL54050IRUZ-T offers superior rON and matching for precision signal paths, while TMUX1574RTER trades off on-resistance for extended temperature capability and different packaging-neither is pin-compatible, requiring layout revision.

FAQ
What is the maximum analog signal voltage supported by ISL54500IRUZ-T?
The ISL54500IRUZ-T supports analog signals from 0V to V+, where V+ is the applied supply voltage within +1.8V to +5.5V. For example, with a +3.3V supply, the analog input range is 0V to +3.3V. Exceeding V+ or going below GND forward-biases internal ESD diodes, limiting fault current but risking damage if unclamped.
Does ISL54500IRUZ-T require external pull-up or pull-down resistors on the IN pin?
No, ISL54500IRUZ-T does not require external biasing on the IN pin. Its digital input is internally referenced and compatible with 1.8V CMOS logic levels (VINH ≥1.4V, VINL ≤0.5V at +3V supply). Adding external resistors may degrade switching speed and is unnecessary unless system-level noise immunity demands it.
Can ISL54500IRUZ-T be used in bidirectional signal paths?
Yes, ISL54500IRUZ-T is fully bidirectional: signals can flow from COM to NO/NC or from NO/NC to COM with identical rON, capacitance, and leakage characteristics. This enables flexible routing in both source-driven and load-driven configurations without performance penalty.
What thermal considerations apply to ISL54500IRUZ-T in µTDFN package?
The µTDFN package has θJA = 239.2°C/W and θJC = 111.6°C/W. To maintain junction temperature below +150°C, keep power dissipation under 25 mW with standard PCB copper; use thermal vias under the exposed pad for sustained >50 mW operation. Derate rON by ~0.1 Ω per °C above +25°C ambient.
Is ISL54500IRUZ-T still recommended for new designs?
No-Intersil explicitly marks ISL54500IRUZ-T as "NOT RECOMMENDED FOR NEW DESIGNS" with ISL54050IRUZ-T listed as the recommended replacement. While ISL54500IRUZ-T remains available and functional, new designs should evaluate ISL54050IRUZ-T for improved rON and updated support.
