Product details
Overview
MAX4611CSD from Maxim Integrated is a quad, low-voltage, single-pole/single-throw (SPST) CMOS analog switch with four normally closed (NC) channels. It operates from a single +2V to +12V supply, delivers ≤100Ω on-resistance at +5V, matches channel on-resistance within 4Ω max, and supports rail-to-rail analog signal handling (GND to V+). It is used in battery-powered audio routing and low-voltage data-acquisition front-ends where leakage-critical NC switching is required.
For engineers reviewing the MAX4611CSD datasheet, MAX4611CSD pinout, MAX4611CSD application, or MAX4611CSD equivalent, this page provides verified electrical specifications, SO-14 package details, truth-table–validated NC switching behavior, and direct alternatives for low-voltage analog multiplexing and signal gating designs.
Technical Context
The MAX4611CSD implements four independent CMOS transmission-gate switches configured as normally closed (NC), meaning each switch conducts when its digital control input is logic low. Its architecture uses matched P- and N-channel MOSFETs per channel to achieve flat on-resistance (<18Ω variation over full signal range) and low charge injection (1–5pC).
All digital inputs feature TTL/CMOS-compatible thresholds (+0.8V low, +2.4V high at +5V supply), enabling direct interface with microcontrollers without level-shifting. The device guarantees <2nA off-leakage at +85°C and >2kV HBM ESD protection, making it suitable for portable instrumentation and industrial sensor interfaces where signal integrity and power-off isolation are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single supply - enables operation from Li-ion battery (3.0–4.2V) up to industrial 12V rails |
| On-Resistance (max) | 100Ω at +5V - ensures minimal voltage drop and gain error in precision signal paths |
| On-Resistance Match | ≤4Ω between channels - supports accurate differential or ratiometric measurements across switched channels |
| Off-Leakage Current | ≤2nA at +85°C - preserves accuracy in high-impedance sample-and-hold or sensor bias networks |
| Signal Range | Rail-to-rail (GND to V+) - allows full utilization of ADC input range without clamping or level shift |
| Turn-On/Off Time | 35ns / 15ns typical - supports multiplexing of audio and medium-speed data signals up to ~10MHz |
| ESD Protection | >2kV HBM - reduces need for external protection in handheld or field-deployable equipment |
Pinout & Package
The MAX4611CSD is supplied in a 14-pin narrow SO (Small Outline) package with standard JEDEC MS-012AC footprint (5.3mm width, 8.65mm length, 1.75mm height). Pin 1 is marked with a bevelled corner or dot; pin numbering follows counterclockwise convention from top-left.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NC1–NC4 | Normally closed analog terminals - conduct to COMx when INx = LOW; open when INx = HIGH |
| 2, 4, 9, 10 | COM1–COM4 | Common analog nodes - bidirectional signal path shared with corresponding NCx terminal |
| 5, 6, 12, 13 | IN1–IN4 | Digital control inputs - TTL/CMOS-compatible; active-low logic controls NC state |
| 7 | GND | Digital/analog reference ground - must be connected to system ground plane for leakage and noise control |
| 14 | V+ | Positive supply - powers analog and digital sections; bypass with ≥0.1µF ceramic capacitor near pin |
Key Features
| Feature | Design Value |
|---|---|
| Four NC-configured SPST switches | Enables fail-safe signal continuity during power loss or MCU reset - critical for safety interlocks and bias retention |
| Guaranteed on-resistance flatness | ≤18Ω variation over full GND-to-V+ signal range - maintains linearity in audio and sensor conditioning paths |
| TTL/CMOS logic compatibility | +0.8V low / +2.4V high thresholds at +5V - eliminates external level shifters in mixed-signal microcontroller systems |
| Rail-to-rail analog signal handling | Supports input/output from GND to V+ without diode clamping - preserves dynamic range in 12-bit+ data acquisition |
| Low charge injection | 1–5pC - minimizes voltage glitch on high-impedance hold capacitors in sample-and-hold circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4612CSD+ | Two NO + two NC channels vs. four NC - different switching logic per channel pair | Requires dual-control logic for mixed-path routing; not drop-in for pure NC use cases | Select only if design needs both NO and NC functionality in same package |
| ADG1412BRUZ | Quad SPST, but all NO configuration; 1.5Ω typical RON; ±15V dual-supply capable | Not NC-fail-safe; requires active pull-down for default conduction; higher supply headroom needed | Prefer when ultra-low on-resistance or dual-supply operation outweighs NC requirement |
Compared with MAX4612CSD+ and ADG1412BRUZ, the MAX4611CSD uniquely provides four guaranteed NC channels in SO-14 with validated <2nA off-leakage at +85°C - making it the only choice for fail-safe, low-leakage, single-supply analog gating where default continuity is mandatory.

FAQ
What is the maximum supply voltage rating for MAX4611CSD?
The absolute maximum supply voltage (V+) for MAX4611CSD is +13V referenced to GND. Operation above +12V is possible but requires strict adherence to power-supply sequencing (apply V+ before analog/logic signals) and local 0.1µF bypassing. Exceeding +13V risks permanent damage, especially under transient conditions or ±10% tolerance 12V supplies that may peak at 13.2V.
Does MAX4611CSD support rail-to-rail analog signal operation?
Yes, MAX4611CSD supports rail-to-rail analog signal handling from GND to V+. This is confirmed in the Electrical Characteristics table (Analog Signal Range = 0V to V+) and applies across the full operating temperature range. No internal clamping diodes limit the signal swing, enabling full utilization of ADC input ranges and sensor output spans without external level shifting.
What is the guaranteed on-resistance match between channels for MAX4611CSD?
The MAX4611CSD guarantees on-resistance match (ΔRON) of ≤4Ω maximum between any two channels at +25°C, and ≤10Ω over the full commercial temperature range (0°C to +70°C). This specification is measured as RON(max) − RON(min) under identical conditions (V+ = +5V, ICOM = 1mA), ensuring consistent gain and offset behavior across multiplexed signal paths.
Can MAX4611CSD be used with a +3V supply?
Yes, MAX4611CSD operates down to +2V and is fully specified at +3V. At +3V supply, typical on-resistance increases to 360Ω (max 450Ω), off-leakage remains ≤2nA at +85°C, and logic thresholds adjust to VIN_H = 1.0V (min) and VIN_L = 0.5V (max). THD remains below 0.009% at 20Hz–20kHz, confirming suitability for low-voltage audio and sensor interfaces.
Is MAX4611CSD pin-compatible with industry-standard analog switches?
Yes, MAX4611CSD is pin-compatible with the industry-standard 74HC4066 and MAX4066 in the 14-pin narrow SO package. Pin functions (COM/NC/IN/V+/GND) align directly, allowing drop-in replacement where NC functionality and tighter RON matching are required. However, note that 74HC4066 offers only NO configuration and higher leakage (>100nA), so validation of off-state integrity is recommended.
