Product details
Overview
ISL54051IRUZ-T from Renesas (formerly Intersil) is a single-pole, single-throw (SPST), normally open (NO) analog switch optimized for low-voltage, battery-powered systems. It operates from a single +1.8V to +5.5V supply, delivers 0.8Ω typical ON-resistance at 5V, achieves 24ns turn-on/10ns turn-off times, and supports 1.8V logic-compatible control - enabling high-fidelity signal routing in space-constrained portable electronics.
For engineers reviewing the ISL54051IRUZ-T datasheet, ISL54051IRUZ-T pinout, ISL54051IRUZ-T application, or ISL54051IRUZ-T equivalent, this device is selected for ultra-low rON, minimal charge injection (26pC), tight rON flatness (0.25Ω), and compatibility with 1.2×1.0mm µTDFN layouts in handheld audio, medical sensors, and ASIC I/O expansion designs.
Technical Context
The ISL54051IRUZ-T implements a bidirectional CMOS SPST switch architecture with integrated level-shifting logic, enabling 1.8V–5.5V single-supply operation without external biasing. Its V+ and GND pins power both analog switch transistors and digital input circuitry, eliminating need for dual supplies or external level translators.
It features ESD protection diodes on all analog pins (NO, NC, COM), limiting signal voltage to within −0.5V to (V+ + 0.5V); overvoltage tolerance requires proper supply sequencing or external Schottky clamping. The device exhibits consistent −3dB bandwidth (190MHz) and >80dB OFF isolation at 100kHz across its full operating voltage range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON-resistance (rON) | 0.8 Ω at 5V - enables <10mV drop at 100mA, preserving signal integrity in precision analog paths |
| rON flatness | 0.25 Ω at 4.5V - ensures linear gain response over full 0V–V+ analog signal range |
| Turn-on / Turn-off time | 24 ns / 10 ns at 4.5V - supports high-speed multiplexing in audio/video and test equipment |
| Charge injection | 26 pC - minimizes glitch-induced error in sampled-data systems like ADC front-ends |
| OFF isolation | 80 dB at 100kHz - suppresses crosstalk between adjacent channels in multi-signal routing |
| Analog signal range | 0V to V+ - allows rail-to-rail signal switching without clipping or distortion |
| ESD rating (HBM) | >6 kV - provides robust handling during PCB assembly and end-user integration |
Pinout & Package
ISL54051IRUZ-T is packaged in a 6-lead, 0.40mm pitch, 1.2mm × 1.0mm × 0.5mm ultra-thin dual flat no-lead (µTDFN) package (PKG DWG # L6.1.2x1.0A), optimized for high-density portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Digital control input | Accepts 1.8V CMOS logic (0.5V/1.4V thresholds); drives internal level shifter to gate analog switch |
| 2 (V+) | Positive supply rail | Single supply input (1.8V–5.5V); powers analog switch core and digital interface simultaneously |
| 3 (GND) | Ground reference | Common return for analog signals and digital logic; must be low-impedance for noise immunity |
| 4 (NO) | Normally open analog terminal | Open-circuit when IN = 0; connects to COM only when IN = 1 - used for enable-controlled signal insertion |
| 5 (NC) | No-connect terminal | Internally unconnected; must be left floating or tied to GND per layout best practices |
| 6 (COM) | Analog common node | Shared signal path; bidirectionally routes between NO and COM when switch is closed |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low ON-resistance | 0.8Ω at 5V - reduces conduction loss and thermal drift in high-current analog paths |
| 1.8V logic compatibility | Supports direct interfacing with low-voltage microcontrollers and ASIC GPIOs without level shifters |
| Low charge injection | 26pC - prevents voltage step errors at sampling nodes in precision data acquisition |
| Small footprint packaging | 1.2mm × 1.0mm µTDFN - saves >60% board area vs. comparable SOT-23 solutions |
| Rail-to-rail analog range | 0V to V+ - preserves full dynamic range of baseband audio, sensor, and battery-monitoring signals |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUT+T | Higher rON (1.5Ω @ 5V), slower tON/tOFF (45ns/25ns), same µTDFN-6 package | Less suitable for <100mV-drop precision paths; acceptable for general-purpose I/O expansion | Select if lower cost is prioritized over rON and speed; verify layout compatibility with MAX4617's pinout (IN/COM swapped) |
| TMUX1101DCUR | Lower rON (0.5Ω @ 5V), faster tON/tOFF (12ns/6ns), but requires ≥2.5V supply (no 1.8V support) | Not viable for 1.8V logic systems; superior for high-speed industrial PLC modules | Choose only if system operates ≥2.5V and demands sub-15ns switching; ISL54051IRUZ-T remains optimal for true 1.8V–5.5V flexibility |
Compared with MAX4617EUT+T and TMUX1101DCUR, ISL54051IRUZ-T uniquely balances ultra-low rON, 1.8V logic compatibility, and µTDFN size - making it irreplaceable in battery-powered devices where voltage headroom, board area, and analog fidelity are simultaneously constrained.

FAQ
What is the maximum supply voltage rating for ISL54051IRUZ-T?
The absolute maximum supply voltage (V+ to GND) for ISL54051IRUZ-T is 6.5V, but the recommended operating range is +1.8V to +5.5V. Operation above 5.5V risks permanent damage, while operation below 1.8V degrades rON, switching speed, and logic threshold margins. ISL54051IRUZ-T must never be subjected to reverse supply polarity or voltage spikes exceeding these limits without external clamping.
Does ISL54051IRUZ-T support bidirectional analog signal flow?
Yes, ISL54051IRUZ-T is fully bidirectional: analog signals pass equally well from COM to NO or NO to COM when the switch is enabled. This is inherent to its CMOS transmission-gate topology and confirmed by specifications including symmetric rON, charge injection, and OFF capacitance values. ISL54051IRUZ-T does not impose directionality constraints on signal routing.
What is the function of the NC pin on ISL54051IRUZ-T?
Pin 5 (NC) on ISL54051IRUZ-T is a no-connect terminal - it has no internal connection and must remain unconnected in the circuit. Unlike ISL54052 (which uses NC as a functional normally closed terminal), ISL54051IRUZ-T reserves this pin for package symmetry and is not electrically active. Leaving it floating is safe; tying it to GND may improve mechanical stability but offers no electrical benefit.
How does ISL54051IRUZ-T handle analog signals exceeding the supply rails?
ISL54051IRUZ-T includes ESD protection diodes from each analog pin (NO, COM) to V+ and GND. If an analog signal exceeds V+ or drops below GND, the corresponding diode conducts, limiting voltage excursion to ~0.5V beyond the rails. To prevent excessive current, external series resistors or Schottky clamps are required when overvoltage events are expected - ISL54051IRUZ-T itself does not provide active overvoltage protection.
Is ISL54051IRUZ-T RoHS compliant and lead-free?
Yes, ISL54051IRUZ-T is RoHS compliant and lead-free, using NiPdAu (e4) termination finish and Pb-free molding compounds per Intersil's specification. It meets IPC/JEDEC J-STD-020 reflow requirements for MSL Level 1 and is rated for peak reflow temperatures up to 260°C. The "-T" suffix confirms tape-and-reel packaging compatible with automated SMT assembly.
