Product details
Overview
MAX4501EUK-T from Maxim Integrated is a single-pole/single-throw (SPST), normally open (NO), low-voltage CMOS analog switch operating from +2V to +12V single supply. It supports rail-to-rail analog signal switching, exhibits 250Ω on-resistance at +5V, 1nA off-leakage at +25°C, and 75ns turn-on time - enabling precision signal routing in battery-powered audio and data-acquisition systems.
For engineers reviewing the MAX4501EUK-T datasheet, MAX4501EUK-T pinout, MAX4501EUK-T application, or MAX4501EUK-T equivalent, key selection criteria include guaranteed on-resistance over temperature, TTL/CMOS-compatible logic thresholds at +5V, low charge injection (10pC), and SOT23-5 packaging for space-constrained portable designs.
Technical Context
The MAX4501EUK-T implements a CMOS transmission-gate architecture with dual ESD diodes per analog terminal (to V+ and GND), enabling rail-to-rail signal handling while defining leakage paths strictly between signal pins and supply rails - not across switch terminals. Its logic-level translator ensures compatible operation with TTL/CMOS inputs when V+ = +5V, with threshold scaling to ~3V at +12V.
Switching dynamics are governed by gate-drive strength and parasitic capacitance: COM-to-NO on-capacitance is 8pF, off-isolation exceeds –100dB at 100kHz, and charge injection is tightly controlled at 10pC (typ) to minimize transient voltage errors in sample-hold or multiplexer applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single supply - enables direct integration into 3.3V, 5V, and 9V battery or adapter-powered systems without level-shifting. |
| On-Resistance | 250Ω max at +5V, TA = TMIN to TMAX - ensures minimal signal attenuation and gain error in precision sensor or audio signal paths. |
| Off-Leakage Current | 1nA max at +25°C, 10nA max at +85°C - preserves accuracy in high-impedance data-acquisition front-ends and battery-monitoring circuits. |
| Switching Speed | tON = 75ns, tOFF = 50ns (RL = 1kΩ, CL = 35pF) - supports multiplexing of kHz-range sensor signals and audio-band routing without timing bottlenecks. |
| Charge Injection | 10pC max - limits voltage glitch on sampled nodes, critical for 12-bit+ ADC input protection and sample-hold stability. |
| Logic Compatibility | VINH = 2.4V, VINL = 0.8V at +5V supply - guarantees reliable control from standard 5V microcontrollers and FPGA I/O without external buffers. |
| Analog Signal Range | Rail-to-rail (0V to V+) - allows full-scale signal passage in unipolar systems, eliminating need for biasing or clamping networks. |
Pinout & Package
SOT23-5 package (5-pin, 1.6mm × 2.9mm footprint), moisture sensitivity level 1, RoHS-compliant, rated for –40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - V+ | Positive supply rail | Powers internal CMOS switches and logic; sets analog signal upper limit and defines ESD diode conduction thresholds. |
| 2 - NO | Normally open analog terminal | Open-circuit path to COM when IN = LOW; connects to COM when IN = HIGH - used as switched output or input depending on system topology. |
| 3 - IN | Digital control input | TTL/CMOS-compatible logic input; active HIGH enables switch closure (COM ↔ NO); no internal pull-up/down. |
| 4 - GND | Ground reference | Analog and digital common return; ESD diodes reference all analog pins to this node; must be low-impedance for leakage control. |
| 5 - COM | Common analog terminal | Central signal node shared with NO (MAX4501) or NC (MAX4502); bidirectional - functions as input or output based on PCB routing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Supports 0V to V+ signal swing without clipping - eliminates DC biasing components in unipolar sensor interfaces. |
| Guaranteed 250Ω on-resistance | Specified over full –40°C to +85°C range and +4.5V to +5.5V supply - enables predictable gain and channel matching in multi-channel muxes. |
| Low 10pC charge injection | Minimizes voltage step on high-Z nodes during switching - essential for maintaining accuracy in sample-and-hold and programmable-gain amplifier stages. |
| 1nA max off-leakage at +25°C | Reduces measurement drift in µA-range current sensing and high-value resistor-divider networks. |
| 75ns/50ns switching times | Enables >10kHz multiplexing rates in data loggers and multi-sensor monitoring systems without inter-channel crosstalk penalties. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4501EXK-T | Identical electrical specs but SC70-5 package (1.25mm × 2.0mm vs. SOT23-5's 1.6mm × 2.9mm); same -40°C to +85°C rating. | Preferred where board area is constrained beyond SOT23-5 limits; requires rework of pick-and-place and solder profile. | Select MAX4501EXK-T only if footprint reduction justifies SC70 assembly complexity and higher unit cost. |
| ADG801BRMZ | Lower on-resistance (0.3Ω typ at 5V) but narrower supply range (+1.8V to +5.5V); 1pC charge injection; ±0.5pA leakage. | Better for ultra-low-RON, low-voltage (<5V) systems; unsuitable for 9V/12V battery or industrial rails. | Choose ADG801BRMZ for sub-1Ω precision switching below 5.5V; retain MAX4501EUK-T for wider supply flexibility and proven 12V operation. |
Compared with MAX4501EXK-T, the MAX4501EUK-T offers larger SOT23-5 handling margin and broader distributor availability; versus ADG801BRMZ, it trades higher RON for guaranteed 12V compatibility and robustness in mixed-supply portable systems.

FAQ
What is the maximum supply voltage rating for the MAX4501EUK-T?
The MAX4501EUK-T has an absolute maximum V+ rating of +13V, with continuous operation supported from +2V to +12V. Operation above +12V risks permanent damage, and the device is characterized and guaranteed only up to +12V per its electrical specifications table. Always observe the –0.3V to +13V absolute maximum rating on V+ relative to GND.
Does the MAX4501EUK-T support bidirectional analog signal flow?
Yes, the MAX4501EUK-T supports fully bidirectional analog signal flow between the COM and NO terminals. The device contains no internal polarity constraints - signals pass with identical on-resistance, leakage, and bandwidth in either direction, as confirmed by its rail-to-rail specification and pin description stating "NO, NC, and COM pins are identical and interchangeable."
What is the guaranteed on-resistance of the MAX4501EUK-T at +3V supply?
The MAX4501EUK-T does not guarantee on-resistance at +3V in its datasheet. While typical RON is 800Ω at +3V (per +3V supply characterization table), only the +5V condition specifies a guaranteed maximum of 250Ω. For designs requiring assured performance at 3V, derating or validation at system level is necessary - the 250Ω guarantee applies strictly at +4.5V to +5.5V.
Can the MAX4501EUK-T be used with 3.3V logic control signals when powered from +5V?
Yes, the MAX4501EUK-T accepts 3.3V logic-high signals when V+ = +5V. Its VINH threshold is specified as 2.4V min, and 3.3V exceeds this by 0.9V - ensuring reliable turn-on. However, ensure the 3.3V driver can sink/source ≤10µA (IINH/IINL spec) and that ground references between logic and switch are common.
Is the MAX4501EUK-T pin-compatible with the MAX4502EUK-T?
No, the MAX4501EUK-T and MAX4502EUK-T are functionally complementary (NO vs. NC) but share identical pinouts in SOT23-5: V+, NO/NC, IN, GND, COM. Pin mapping is identical; only the internal switch state differs. Swapping them requires logic inversion or firmware update - no PCB change is needed, but system behavior reverses.
