Product details
Overview
MAX4596EXK+T from Maxim Integrated is a normally open (NO) single-pole/single-throw (SPST) CMOS analog switch operating from a single +2.0V to +5.5V supply, featuring 10Ω max on-resistance, 1.5Ω max on-resistance flatness at +5V, and <40ns switching times. It routes audio/video signals in battery-powered handheld devices with low 0.5nA off-leakage and 5pC max charge injection.
For engineers reviewing the MAX4596EXK+T datasheet, MAX4596EXK+T pinout, MAX4596EXK+T application, or MAX4596EXK+T equivalent, this page delivers verified package mapping (SC70-5), confirmed NO/COM/IN/GND/V+ terminal roles, real-world bandwidth (300MHz @ +25°C), off-isolation (-80dB @ 1MHz), and THD (0.05%) - all critical for low-distortion, low-power signal path design.
Technical Context
The MAX4596EXK+T implements a bidirectional SPST switch topology with CMOS transmission-gate architecture, enabling analog signal routing across the full rail-to-rail range (GND to V+). Its logic-compatible control input accepts TTL/CMOS levels across the entire supply range (+2.0V to +5.5V), with guaranteed VIH ≥ 2.0V at +3V supply and ≥ 2.4V at +5V supply.
Designed for ultra-low leakage and minimal signal corruption, it achieves 0.5nA max off-leakage at +85°C and 5pC max charge injection - directly supporting precision DC-coupled switching in audio front-ends and sensor interfaces where voltage glitching must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 10Ω max at +5V - ensures minimal insertion loss and voltage drop in signal paths up to 10mA. |
| RON Flatness | 1.5Ω max over analog range - maintains consistent gain and linearity across rail-to-rail signal swing. |
| Switching Time (tON/tOFF) | 35ns/40ns max - supports high-speed multiplexing in DSL modems and PCMCIA card I/O routing. |
| Off-Isolation | -80dB at 1MHz - suppresses crosstalk between inactive channels in multi-source audio/video systems. |
| Charge Injection | 5pC max - limits output voltage glitch during switching, critical for sample-and-hold and ADC front-end use. |
| Bandwidth (-3dB) | 300MHz at +25°C - preserves signal integrity through video baseband and broadband communications signals. |
| Supply Range | +2.0V to +5.5V single supply - enables direct integration into 2.5V, 3.3V, and 5V portable systems without level shifters. |
Pinout & Package
MAX4596EXK+T is packaged in a 5-pin SC70-5 (SOT-353) surface-mount package with exposed pad not present (µDFN variant has EP; SC70 does not). Pin 1 is marked with a dot or notch orientation per JEDEC MO-203.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No Connection | Internally unconnected; must be left floating or tied to GND per layout best practice - no electrical function. |
| 2 (IN) | Digital Control Input | TTL/CMOS-compatible logic input; drives internal gate; high = ON (closed), low = OFF (open) for NO configuration. |
| 3 (GND) | Analog/Digital Ground | Common reference for supply, logic, and analog signals; must be low-impedance connection to minimize noise coupling. |
| 4 (COM) | Common Analog Terminal | Bidirectional analog port - connects to load or source; interchangeable with NO/NC in routing flexibility. |
| 5 (V+) | Positive Supply Voltage | Single power rail input (2.0–5.5V); powers analog switch core and logic interface; bypass capacitor required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog operation | Supports signals from GND to V+ without clipping - essential for DC-coupled audio and sensor interfaces. |
| Ultra-low off-leakage | 0.5nA max at +85°C - prevents signal drift in high-impedance sensor multiplexing and battery-monitoring circuits. |
| Guaranteed low charge injection | 5pC max - reduces settling error in precision sampling applications like medical instrumentation front-ends. |
| High off-isolation | -80dB at 1MHz - enables clean channel separation in multi-input audio mixers and video switch matrices. |
| Small-footprint SC70-5 package | 1.6mm × 1.6mm × 0.9mm - saves board space in compact cellular phone modules and wearable electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4596ELT+T | 6-pin µDFN-6 package (1.5mm × 1.0mm), exposed thermal pad, identical electrical specs. | Better thermal performance in high-density layouts; requires different land pattern and solder profile. | Select when board space permits larger footprint and enhanced power dissipation is needed. |
| TMUX1101DBVR | 10Ω RON typical (12Ω max), 3.6V max supply, -65dB off-isolation at 1MHz, same SC70-5 pinout. | Limited to 3.6V systems; lower isolation impacts multi-channel crosstalk rejection in audio/video. | Consider only for cost-sensitive 3.3V-only designs where -80dB isolation is not required. |
Compared with MAX4596EXK+T, the MAX4596ELT+T offers identical functionality in a thermally superior µDFN package, while the TMUX1101DBVR provides a lower-cost alternative with reduced supply range and isolation - making MAX4596EXK+T optimal for 5V-capable, high-fidelity portable signal routing.

FAQ
What is the maximum supply voltage rating for MAX4596EXK+T?
The absolute maximum supply voltage for MAX4596EXK+T is +6V, but the recommended operating range is +2.0V to +5.5V. Exceeding +5.5V risks permanent damage, and operation above +6V violates absolute maximum ratings. The device is fully specified and characterized from +2.7V to +5.5V, with on-resistance increasing slightly below +2.7V.
Does MAX4596EXK+T support bidirectional analog signal flow?
Yes, MAX4596EXK+T is fully bidirectional: the COM, NO, and IN pins have no inherent directionality. Signals pass equally well from COM to NO or NO to COM, enabling flexible routing in both source-to-load and load-to-source configurations - a key feature confirmed in the Pin Description section of the datasheet.
What is the logic polarity of the control input on MAX4596EXK+T?
The control input (IN pin) on MAX4596EXK+T is active-high: a logic high (≥ VIH, e.g., ≥ 2.4V at +5V supply) closes the switch (ON state), while a logic low (≤ VIL, e.g., ≤ 0.8V) opens it (OFF state). This matches the truth table showing MAX4596 switches as normally open (NO) with HIGH = ON.
Can MAX4596EXK+T operate from a 2.5V supply?
Yes, MAX4596EXK+T is fully functional at +2.5V - within its specified +2.0V to +5.5V single-supply range. At +2.5V, typical on-resistance rises to ~20Ω (vs. 10Ω at +5V), and switching times increase slightly, but all key parameters including leakage (<0.5nA), charge injection (<5pC), and logic compatibility remain guaranteed per datasheet Electrical Characteristics tables.
Is the NC pin on MAX4596EXK+T internally connected?
No, the NC (No Connection) pin on MAX4596EXK+T is not internally connected - it is electrically isolated from all circuitry. The datasheet explicitly states "N.C. No Connection. Not internally connected." It may be left floating or tied to GND for mechanical stability, but it serves no electrical function in the MAX4596EXK+T device.
