Product details
Overview
MAX4066CSD from Maxim Integrated is a quad, single-pole single-throw (SPST), CMOS analog switch optimized for low-voltage operation (2.0V to 16V), featuring 45Ω on-resistance at 12V, 2Ω channel-to-channel matching (MAX4066A variant), and 0.5µW quiescent power consumption. It serves as a bilateral signal routing device in battery-powered instrumentation and audio path switching.
For engineers reviewing the MAX4066CSD datasheet, MAX4066CSD pinout, MAX4066CSD application, or MAX4066CSD equivalent, key selection criteria include guaranteed on-resistance flatness (≤6Ω), sub-1nA off-leakage at +25°C, TTL/CMOS-compatible control inputs, and SO-14 package compatibility with legacy 74HC4066 layouts.
Technical Context
The MAX4066CSD implements four independent SPST switches using complementary CMOS transistor pairs per channel, enabling bidirectional analog signal conduction with rail-to-rail voltage handling (GND to V+). Its logic interface accepts standard TTL/CMOS thresholds across the full supply range.
Design-level performance is defined by guaranteed on-resistance matching (≤4Ω for MAX4066, ≤2Ω for MAX4066A), low charge injection (≤10pC), and high dynamic performance: >100MHz bandwidth, −86dB crosstalk, and −58dB off-isolation at 1MHz - all specified over 0°C to +70°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2.0V to +16V single supply - supports direct integration into 3.3V, 5V, and 12V systems without level-shifting |
| On-Resistance (12V) | 45Ω max - ensures minimal signal attenuation and gain error in precision sensor or audio signal paths |
| Channel Matching (∆RON) | 4Ω max (MAX4066) - critical for multiplexer accuracy and differential signal integrity |
| Off-Leakage Current | 1nA max at +25°C - preserves DC accuracy in sample-and-hold and high-impedance sensor interfaces |
| Bandwidth | >100MHz - enables reliable switching of video, RF sampling, and fast data-acquisition signals |
| Power Consumption | 0.5µW typical - extends battery life in portable medical, test, and IoT edge devices |
| ESD Protection | >2000V HBM - reduces need for external protection in consumer and industrial PCB layouts |
Pinout & Package
MAX4066CSD is housed in a 14-pin narrow SO (Small Outline) package, 150-mil body width, with standard JEDEC MS-012AC footprint. Pin 1 is marked via notch or dot; pin count and spacing match industry-standard SO-14 layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 13 | NO1–NO4 | Normally open analog terminals - connect to signal sources when switch is enabled; bidirectional |
| 2, 5, 10, 12 | COM1–COM4 | Common analog terminals - serve as input/output junctions; support rail-to-rail signal swing (GND to V+) |
| 6, 7, 12, 14 | IN1–IN4 | TTL/CMOS logic control inputs - active-high; drive internal gate circuitry with <0.5µA input current |
| 8 | GND | Analog/digital ground reference - must be low-impedance return path for leakage and switching currents |
| 14 | V+ | Positive supply - powers analog switch core and logic interface; absolute max +17V |
Key Features
| Feature | Design Value |
|---|---|
| PIN-COMPATIBLE WITH 74HC4066 | Direct drop-in replacement in existing SO-14 layouts - no PCB redesign required for upgrade to lower RON and leakage |
| GUARANTEED ON-RESISTANCE MATCHING | ≤4Ω max between channels - maintains amplitude balance in multi-channel instrumentation and audio summing applications |
| LOW CHARGE INJECTION | ≤10pC - minimizes voltage glitch on sampled nodes, critical for precision ADC front-ends and sample-and-hold circuits |
| RAIL-TO-RAIL SIGNAL HANDLING | VCOM/VNO = 0V to V+ - eliminates clipping in single-supply audio, sensor, and DAC output routing |
| LOW DISTORTION | 0.03% THD - preserves fidelity in line-level and headphone driver signal paths |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4066ACSD | Same SO-14 package and pinout; improved channel matching (2Ω max vs. 4Ω) and lower leakage (100pA vs. 1nA) | Better suited for high-precision multiplexing where channel uniformity and ultra-low leakage are critical | Select MAX4066ACSD when upgrading from MAX4066CSD for tighter matching or lower temperature drift in metrology-grade designs |
| ADG408BRUZ | 8-channel, single-pole single-throw; higher on-resistance (100Ω typ); different pinout and package (TSSOP-16) | Requires PCB layout change; supports more channels but with reduced bandwidth (30MHz) and higher distortion (0.05%) | Choose ADG408BRUZ only if additional channel count outweighs need for MAX4066CSD's low RON, low leakage, and SO-14 compatibility |
Compared with MAX4066CSD, MAX4066ACSD offers measurable improvements in matching and leakage without layout impact, while ADG408BRUZ trades off performance and footprint for channel density - making MAX4066CSD optimal for cost-sensitive, space-constrained quad-switch applications requiring proven low-RON and low-power operation.

FAQ
What is the maximum supply voltage rating for MAX4066CSD?
The MAX4066CSD has an absolute maximum supply voltage (V+) of +17V. Continuous operation is guaranteed from +2.0V to +16V across the 0°C to +70°C temperature range. Exceeding +17V risks permanent damage, and proper power sequencing (V+ before logic inputs) is recommended to avoid latch-up or overstress conditions in the MAX4066CSD.
Does MAX4066CSD support rail-to-rail analog signal switching?
Yes, the MAX4066CSD supports rail-to-rail analog signal handling: its COM and NO terminals operate from GND to V+, enabling full-swing signal routing without clipping. This capability is explicitly guaranteed in the datasheet for analog signal ranges of 0V to V+, making the MAX4066CSD suitable for single-supply audio, sensor, and DAC interface applications.
Is MAX4066CSD pin-compatible with the 74HC4066?
Yes, the MAX4066CSD is pin-compatible with the 74HC4066 in the 14-pin SO package. Both share identical pin assignments for IN1–IN4, COM1–COM4, NO1–NO4, V+, and GND. The MAX4066CSD improves upon the 74HC4066 with lower on-resistance, tighter channel matching, and superior leakage specs - allowing direct replacement without layout changes.
What is the typical on-resistance of MAX4066CSD at 3.3V supply?
At +3.3V supply, the MAX4066CSD exhibits a typical on-resistance (RON) of approximately 170Ω, with a maximum guaranteed value of 170Ω at +25°C. This value increases slightly at temperature extremes and lower supply voltages, as confirmed in the +3V supply electrical characteristics table of the MAX4066CSD datasheet.
Can MAX4066CSD be used in audio applications?
Yes, the MAX4066CSD is explicitly qualified for low-distortion audio applications, with 0.03% total harmonic distortion (THD) and >100MHz bandwidth. Its low charge injection (≤10pC), low crosstalk (−86dB), and rail-to-rail signal handling make the MAX4066CSD well-suited for microphone preamp routing, line-level switching, and headphone signal path control in portable audio systems.
