Product details
Overview
MAX4504CUK-T from Maxim Integrated is a normally closed (NC), low-voltage, dual-supply SPST CMOS analog switch in SOT23-5 package. It operates from ±1V to ±6V supplies, supports rail-to-rail analog signals up to ±4.5V, exhibits 250Ω on-resistance at ±5V, and delivers 1nA off-leakage at +25°C - ideal for precision signal routing in battery-powered audio and data-acquisition systems.
For engineers reviewing the MAX4504CUK-T datasheet, MAX4504CUK-T pinout, MAX4504CUK-T application, or MAX4504CUK-T equivalent, key selection criteria include NC switching behavior, dual-supply voltage range compatibility, guaranteed on-resistance and leakage specs across temperature, charge injection (≤10pC), and SOT23-5 footprint constraints for space-constrained portable designs.
Technical Context
The MAX4504CUK-T implements a single-pole/single-throw analog switch with internal CMOS transmission gate architecture biased by independent V+ and V− rails - no ground reference required. Its logic input accepts CMOS-compatible levels referenced to V+, enabling operation without a dedicated GND pin.
Switching is controlled by an IN pin that toggles the NC path: logic high opens the switch (disconnected), logic low closes it (conductive). Signal paths (COM, NC) are bidirectional, support rail-to-rail analog voltages, and feature ESD diodes clamped to V+ and V− - critical for robustness in handheld and PCMCIA applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±1V to ±6V dual supply - enables direct integration into split-rail sensor or audio front-end stages without level-shifting. |
| On-Resistance | 250Ω max at ±5V - ensures minimal signal attenuation and THD impact in 50Ω–600Ω audio/data paths. |
| Off-Leakage Current | 1nA max at +25°C - preserves accuracy in high-impedance measurement nodes (e.g., sensor multiplexing). |
| Charge Injection | 10pC max - limits voltage glitch on sampled-hold capacitors in data-acquisition systems. |
| Switching Speed | tON = 150ns, tOFF = 100ns - supports multiplexing of signals up to ~1MHz without timing skew issues. |
| Analog Signal Range | Rail-to-rail: V− to V+ - allows full utilization of supply headroom in low-voltage portable systems. |
| Logic Compatibility | CMOS-input with V+ reference - eliminates need for external level translators when driven by same-supply microcontrollers. |
Pinout & Package
SOT23-5 surface-mount package (3.0mm × 1.7mm × 1.3mm), lead pitch 0.95mm, RoHS-compliant, tape-and-reel packaged for automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - COM | Analog common terminal | Bidirectional signal path hub; connects to load or source depending on routing topology. |
| 2 - NC | Analog normally closed terminal | Conducts to COM when IN = low; open when IN = high - defines default-closed signal path. |
| 3 - V− | Negative analog/digital supply | Sets lower rail for analog signal swing and powers internal logic bias network; no ground connection required. |
| 4 - IN | Digital control input | CMOS-compatible logic pin referenced to V+; low = closed path, high = open path. |
| 5 - V+ | Positive analog/digital supply | Sets upper rail for analog signal swing and provides logic pull-up reference; powers internal level translator. |
Key Features
| Feature | Design Value |
|---|---|
| No ground pin required | Enables true dual-supply operation in isolated or floating systems - simplifies PCB layout and eliminates ground-loop risks. |
| Guaranteed 1nA off-leakage at +25°C | Maintains signal integrity in high-Z medical sensor or precision instrumentation inputs without calibration drift. |
| 10pC max charge injection | Reduces settling error in sample-and-hold circuits - critical for 12-bit+ ADC front-ends. |
| 150ns turn-on time | Supports fast channel switching in multi-sensor data loggers without introducing measurable latency. |
| ±1V minimum supply operation | Extends battery life in coin-cell-powered devices by enabling functionality down to depleted cell voltages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4504EUK-T | Same function and pinout; extended temperature range (−40°C to +85°C) vs. MAX4504CUK-T (0°C to +70°C) | Required for industrial or automotive-adjacent environments where ambient exceeds 70°C | Select MAX4504EUK-T when operating temperature must exceed +70°C; otherwise MAX4504CUK-T suffices for commercial-grade portable devices. |
| ADG1419BRMZ | Single-supply only (up to 36V), higher RON (2.5Ω typ), no dual-supply capability, different pinout (8-MSOP) | Designed for high-voltage industrial I/O modules, not low-voltage battery systems | Not interchangeable - ADG1419BRMZ lacks dual-supply support and NC default state; use only if redesigning for single-rail 5V–36V operation. |
Compared with MAX4504CUK-T, MAX4504EUK-T offers identical electrical performance with broader thermal qualification, while ADG1419BRMZ targets high-voltage industrial use cases and cannot replace MAX4504CUK-T without board-level changes and supply architecture revision.

FAQ
What is the default switching state of the MAX4504CUK-T?
The MAX4504CUK-T is a normally closed (NC) analog switch: when the IN pin is logic low (≤ V− + 0.4V), the NC and COM terminals are conductive; when IN is logic high (≥ V+ − 1.5V), the path opens. This fail-safe behavior ensures signal continuity during power-up or control failure - a key distinction from the NO MAX4503CUK-T variant.
Does the MAX4504CUK-T require a ground connection to operate?
No, the MAX4504CUK-T does not require a ground connection. It operates using only V+ and V− supply pins, with internal logic referenced to V+. The absence of a GND pin simplifies design in floating or isolated systems and eliminates ground-loop concerns in mixed-signal PCB layouts containing the MAX4504CUK-T.
What is the maximum analog signal voltage the MAX4504CUK-T can handle?
The MAX4504CUK-T supports rail-to-rail analog signals from V− to V+, meaning its maximum analog voltage range equals the difference between its applied V+ and V− supplies. With ±5V supplies, it handles ±4.5V signals; with ±1V supplies, it handles ±0.9V - always staying within 0.3V of either rail to avoid forward-biasing internal ESD diodes.
Can the MAX4504CUK-T be used with single-supply systems?
No - the MAX4504CUK-T is designed exclusively for dual-supply operation (±1V to ±6V). For single-supply applications (e.g., 3V or 5V only), Maxim specifies the pin-compatible MAX4502 or MAX4501. Attempting single-supply use with MAX4504CUK-T violates absolute maximum ratings and may cause permanent damage or unpredictable switching behavior.
How does charge injection affect system performance when using the MAX4504CUK-T?
Charge injection in the MAX4504CUK-T is guaranteed ≤10pC, causing a voltage glitch ΔV = Q/CL on downstream capacitive nodes (e.g., sample-and-hold capacitors). In a 1000pF hold capacitor, this results in ≤10mV error - manageable in 10-bit systems but requiring guard-band design or correlated double sampling in 12-bit+ data-acquisition systems using the MAX4504CUK-T.
