Product details
Overview
MAX4541CSA+T from Maxim Integrated is a dual single-pole/single-throw (SPST), normally open analog switch IC operating from a single +2.7V to +12V supply. It delivers 60Ω max on-resistance, 2Ω max RON matching between channels, 5pC max charge injection, and 100ns max tOFF, enabling precision signal routing in low-power, battery-operated instrumentation and portable audio systems.
For engineers reviewing the MAX4541CSA+T datasheet, MAX4541CSA+T pinout, MAX4541CSA+T application, or MAX4541CSA+T equivalent, key selection criteria include guaranteed break-before-make timing (not applicable to MAX4541), SOT23-8 package compatibility, +5V/±10% supply operation with TTL/CMOS logic inputs, and ≤10nA leakage at +85°C for high-impedance sample-and-hold front ends.
Technical Context
The MAX4541CSA+T implements two independent NO SPST switches with CMOS control architecture, supporting bidirectional analog signal flow from GND to V+ across both COM–NO paths. Its low 5µW quiescent power and 100pA max off-leakage at +25°C enable use in always-on sensor interfaces without compromising battery life.
Switching performance is defined by 35ns typical tON and 25ns typical tOFF at +5V, with RON flatness held to 6Ω max over the full signal range - critical for minimizing harmonic distortion in audio and DAC output switching applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.7V to +12V single supply - supports direct integration with 3.3V, 5V, and 12V system rails without level shifting |
| On-Resistance (RON) | 60Ω max at +5V - ensures minimal signal attenuation and gain error in precision analog paths |
| RON Matching | 2Ω max between channels - enables matched gain/phase response in differential or dual-path circuits |
| Charge Injection | 5pC max - reduces voltage glitch and settling time in sample-and-hold and multiplexed ADC front ends |
| Off-Leakage Current | 10nA max at +85°C - preserves accuracy in high-impedance sensor nodes and integrator circuits |
| Turn-On/Off Time | tON = 35ns, tOFF = 25ns typ at +5V - supports >10MHz switching rates in high-speed data acquisition |
| ESD Protection | 2000V per Method 3015.7 - provides robust handling during PCB assembly and field operation |
Pinout & Package
MAX4541CSA+T is housed in an 8-pin SO (Small Outline) package with standard 1.27mm pitch, footprint compatible with industry-standard SOIC-8 layouts and reflow profiles.

|---|---|---|
| 1 | COM1 | Analog common terminal for Switch 1 - bidirectional path connected to NO1 when IN1 = high |
| 2 | IN1 | Digital control input for Switch 1 - TTL/CMOS-compatible; active-high logic drives COM1–NO1 closed |
| 3 | GND | Ground reference for analog and digital circuitry - must be low-impedance return path for leakage and switching currents |
| 4 | NO1 | Normally open terminal for Switch 1 - connects to COM1 only when IN1 is asserted |
| 5 | NO2 | Normally open terminal for Switch 2 - connects to COM2 only when IN2 is asserted |
| 6 | IN2 | Digital control input for Switch 2 - independent TTL/CMOS-compatible control, synchronous or asynchronous operation supported |
| 7 | COM2 | Analog common terminal for Switch 2 - bidirectional path connected to NO2 when IN2 = high |
| 8 | V+ | Positive supply rail - powers internal switch matrix and logic; absolute max rating is +13V |
Key Features
| Feature | Design Value |
|---|---|
| Low RON flatness | 6Ω max variation across 0V to V+ signal range - maintains linearity in audio and video signal switching |
| TTL/CMOS logic compatibility | Guaranteed VINH = 2.4V / VINL = 0.8V at +5V supply - eliminates need for external level translators |
| Pin compatibility | Direct replacement for MAX323/MAX324/MAX325 in SO-8 layout - enables drop-in upgrade of legacy designs |
| Low power consumption | <5µW quiescent - extends battery life in portable medical monitors and handheld test equipment |
| Bidirectional analog signal path | COM/NO terminals support signal flow in either direction - simplifies PCB routing in multiplexer and crosspoint applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4541EKA-T | SOT23-8 package, -40°C to +85°C temp range vs. MAX4541CSA+T's 0°C to +70°C and SO-8 | Preferred for extended-temperature industrial or automotive environments requiring compact footprint | Select MAX4541EKA-T when board space is constrained and wide temperature operation is required |
| MAX323ESA+ | Higher 90Ω max RON, no guaranteed charge injection spec, same SO-8 pinout | Suitable for non-critical general-purpose switching where cost is prioritized over precision | Choose MAX323ESA+ only if RON tolerance >30Ω and charge injection <10pC are acceptable |
Compared with MAX4541CSA+T, MAX4541EKA-T offers identical electrical performance in a smaller SOT23-8 package with extended temperature range, while MAX323ESA+ trades precision (higher RON, unguaranteed charge injection) for legacy compatibility and lower cost in SO-8 form factor.

FAQ
What is the maximum supply voltage rating for MAX4541CSA+T?
The MAX4541CSA+T has an absolute maximum supply voltage (V+) of +13V. Operation is specified from +2.7V to +12V; exceeding +13V risks permanent damage. The device includes internal diode clamping on analog pins, but external protection diodes are recommended if analog signals may exceed V+ or dip below GND.
Does MAX4541CSA+T support break-before-make switching?
No, MAX4541CSA+T does not provide guaranteed break-before-make operation. That feature is explicitly documented only for MAX4543 and MAX4544 variants. MAX4541CSA+T implements two independent normally open SPST switches with no timing interlock between channels.
Can MAX4541CSA+T operate from a +3.3V supply?
Yes, MAX4541CSA+T is fully specified for +3.3V operation (V+ = +3.0V to +3.6V). At +3.3V, typical RON is 275Ω, tON is 80ns, and tOFF is 50ns. Logic inputs remain TTL/CMOS-compatible, with VINH = 2.4V and VINL = 0.8V guaranteed across the full temperature range.
What is the thermal resistance (θJA) of the SO-8 package used by MAX4541CSA+T?
The SO-8 package for MAX4541CSA+T has a thermal resistance θJA of 5.88°C/W, meaning it dissipates 471mW continuously at +70°C ambient before derating begins. Above +70°C, power dissipation must be reduced by 5.88mW per °C rise to maintain safe junction temperature.
Is MAX4541CSA+T pin-compatible with MAX323ESA+?
Yes, MAX4541CSA+T is pin-compatible with MAX323ESA+ in the SO-8 package. Both share identical pin assignments for V+, IN1, GND, NO1, NO2, IN2, COM2, and COM1. This allows direct substitution in existing layouts, though MAX4541CSA+T offers superior RON, leakage, and charge injection specs.
