Product details
Overview
ISL54500IHZ-T from Intersil is a single-pole/double-throw (SPDT) analog switch optimized for battery-powered portable equipment, featuring 5.0 Ω ON-resistance at +5 V, 22 ns turn-on time, and guaranteed break-before-make switching. It operates from a single +1.8 V to +5.5 V supply, supports 1.8 V CMOS logic compatibility at +3 V, and is housed in a 6-lead SOT-23 package.
For engineers reviewing the ISL54500IHZ-T datasheet, ISL54500IHZ-T pinout, ISL54500IHZ-T application, or ISL54500IHZ-T equivalent, this page delivers verified electrical specs, validated SOT-23 pin mapping, confirmed SPDT mux use cases in audio/video routing and cellular ASIC signal expansion, and two technically documented alternative parts with explicit functional and packaging differences.
Technical Context
The ISL54500IHZ-T implements a committed SPDT architecture with one normally open (NO) and one normally closed (NC) channel, enabling true 2:1 multiplexing without external logic. Its sub-microamp quiescent current (0.5 µA max) and rail-to-rail analog signal range (0 V to V+) support low-power, high-fidelity signal routing in space-constrained designs.
Internal level shifters translate 1.8 V–3.6 V CMOS logic inputs to full V+/GND gate drive, ensuring reliable switching across the entire supply range. Break-before-make timing (18 ns min) prevents signal shorting during state transitions, while ESD robustness (6 kV HBM) and latch-up immunity are enhanced by internal protection diodes and recommended external series resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON-resistance (rON) | 5.0 Ω at +5 V - enables low insertion loss in 50 Ω RF/audio paths and minimizes voltage drop under 100 mA load |
| Turn-on / Turn-off time | 22 ns / 15 ns at +4.5 V - supports high-speed signal routing in digital interface muxing and test equipment |
| Supply voltage range | +1.8 V to +5.5 V - powers directly from Li-ion battery (3.0–4.2 V), 3.3 V rails, or regulated 1.8 V logic domains |
| rON matching | 46 mΩ typical - ensures balanced channel performance critical for differential or precision analog switching |
| OFF-isolation | 75 dB at 1 MHz - suppresses crosstalk between active and inactive signal paths in multi-source audio/video systems |
| ESD rating (HBM) | 6 kV - meets IEC 61000-4-2 Level 4 for handheld device front-end protection without added TVS |
| Package | 6-lead SOT-23 (MDP0038) - footprint-compatible with industry-standard discrete transistor layouts; 2.9 mm × 2.8 mm × 1.3 mm height |
Pinout & Package
ISL54500IHZ-T is packaged in a Pb-free, RoHS-compliant 6-lead SOT-23 (MDP0038) with standard gull-wing leads and 0.95 mm pitch. The package is MSL-1 rated and compatible with SnPb and Pb-free reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | Analog Normally Closed terminal | Connected to COM when IN = 0; used for default-path routing or fail-safe signal continuity |
| 2 (IN) | Digital control input | Accepts 1.8 V CMOS logic (0.5 V/1.4 V thresholds at +3 V); drives internal level shifter to control switch state |
| 3 (NO) | Analog Normally Open terminal | Connected to COM when IN = 1; enables on-demand signal path activation in multiplexer configurations |
| 4 (GND) | Ground reference | Return path for analog signals and digital logic; must be low-impedance to minimize noise coupling into rON |
| 5 (COM) | Analog common terminal | Shared I/O node for bidirectional signal flow; supports rail-to-rail analog voltages up to V+ |
| 6 (V+) | Positive power supply | Single supply input (+1.8 V to +5.5 V); powers internal CMOS switches and logic; requires 100 Ω series resistor for enhanced ESD/latch-up immunity |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | 18 ns minimum delay prevents momentary shorting between NC and NO paths during switching - essential for protecting downstream circuitry |
| rON flatness | 1.1 Ω at +4.5 V - maintains consistent signal attenuation across full analog input range (0 V to V+), reducing harmonic distortion |
| Low charge injection | 16 pC typical - minimizes voltage glitches on high-impedance nodes (e.g., ADC inputs or sensor interfaces) during switching |
| High-frequency bandwidth | 350 MHz −3 dB point - supports clean routing of video clocks, USB 1.1 data, and other high-speed baseband signals |
| 1.8 V logic compatibility | Validated at +3 V supply with VINL ≤ 0.5 V and VINH ≥ 1.4 V - enables direct interfacing with ultra-low-voltage microcontrollers and FPGAs |

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 | Same SPDT topology but in 6-lead µTDFN (1.2 mm × 1.0 mm); 4.2 Ω rON at +4.5 V; no SOT-23 option | Better thermal resistance (θJA = 239°C/W vs. 260°C/W) and smaller footprint - preferred for ultra-dense layouts | Select ISL54050IRUZ-T when board area is critical and µTDFN assembly capability exists; not pin-compatible with ISL54500IHZ-T |

Compared with ISL54500IHZ-T, ISL54050IRUZ-T offers superior thermal performance and smaller size but mandates µTDFN rework, while TMUX1574DSGR provides higher ESD immunity and wider voltage tolerance at the cost of non-interchangeable pin mapping and larger footprint.

FAQ
What is the maximum analog signal voltage range supported by the ISL54500IHZ-T?
The ISL54500IHZ-T supports a rail-to-rail analog signal range from 0 V to V+, where V+ is the positive supply voltage. With V+ operating from +1.8 V to +5.5 V, the analog input/output can swing fully across that supply range - for example, 0 V to +3.3 V when powered from a 3.3 V rail. This ensures compatibility with common logic and sensor output levels without level-shifting circuitry.
Does the ISL54500IHZ-T require external components for reliable operation?
Yes - Intersil recommends adding a 100 Ω resistor in series with the V+ pin to enhance ESD and latch-up immunity during system-level transients. Additionally, Schottky diodes may be added to analog signal pins if overvoltage conditions beyond V+ or below GND cannot be avoided. The ISL54500IHZ-T itself draws only 0.5 µA typical supply current, so these external components introduce negligible impact on normal operation.
Is the ISL54500IHZ-T pin-compatible with other members of the ISL54500 family?
No - the ISL54500IHZ-T uses the 6-lead SOT-23 package (MDP0038) with a specific pinout: Pin 1 = NC, Pin 2 = IN, Pin 3 = NO, Pin 4 = GND, Pin 5 = COM, Pin 6 = V+. In contrast, the ISL54500IRUZ-T variant uses a 6-lead µTDFN package (L6.1.2x1.0A) with entirely different pin numbering and physical layout. They are functionally identical but not mechanically or electrically interchangeable without PCB redesign.
What is the guaranteed break-before-make timing specification for the ISL54500IHZ-T?
The ISL54500IHZ-T guarantees a minimum break-before-make time delay (tD) of 18 ns under full operating conditions (−40°C to +85°C, V+ = +5.5 V). This parameter is measured with RL = 50 Ω and CL = 35 pF, and ensures that the NC path fully disconnects before the NO path connects - preventing momentary shorts that could damage sensitive downstream circuitry or cause signal corruption.
Can the ISL54500IHZ-T operate reliably from a 1.8 V supply in portable applications?
Yes - the ISL54500IHZ-T is fully specified down to +1.8 V, with typical rON = 12.8 Ω and tON/tOFF = 70 ns/52 ns at that voltage. While performance degrades slightly versus +5 V operation (e.g., higher rON, slower switching), it remains functional and stable across the full −40°C to +85°C temperature range, making it suitable for single-cell Li-ion or coin-cell powered devices where ultra-low supply voltage is mandatory.
