Product details
Overview
MAX4066ACSD+T from Maxim Integrated is a quad, single-pole single-throw (SPST), CMOS analog switch optimized for low-voltage operation from +2.0V to +16V, featuring 45Ω on-resistance at 12V, 2Ω channel-to-channel matching, and 100pA off-leakage at +25°C. It serves as a bilateral signal routing device in battery-powered instrumentation and audio path switching.
For engineers reviewing the MAX4066ACSD+T datasheet, MAX4066ACSD+T pinout, MAX4066ACSD+T application, or MAX4066ACSD+T equivalent, key selection criteria include guaranteed on-resistance flatness (≤6Ω), TTL/CMOS-compatible control inputs, low distortion (0.03%), wide bandwidth (>100MHz), and SO-14 package compatibility with legacy 74HC4066 layouts.
Technical Context
The MAX4066ACSD+T implements four independent SPST switches using complementary MOSFET pairs per channel, enabling bidirectional analog signal conduction with rail-to-rail voltage handling (GND to V+). Its architecture guarantees matched on-resistance across all channels and maintains low charge injection (≤10pC) for precision sample-and-hold applications.
Control logic accepts standard TTL/CMOS input thresholds (VINH = 4.0V min at V+ = 12V; VINL = 0.8V max), and internal ESD protection exceeds 2000V per Method 3015.7. The device operates over 0°C to +70°C and supports single-supply configurations without negative rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 45Ω max at V+ = 12V - ensures minimal signal attenuation and voltage drop in low-level analog paths |
| Channel Matching (∆RON) | 2Ω max - enables precise gain-matching in multi-channel signal conditioning or multiplexing |
| Off-Leakage Current | 100pA max at +25°C - preserves accuracy in high-impedance sensor interfaces and battery-monitoring circuits |
| Bandwidth | >100MHz - supports video, RF sampling, and fast data-acquisition signals without roll-off |
| THD | 0.03% - maintains fidelity in audio routing and low-distortion instrumentation front-ends |
| Supply Range | +2.0V to +16V - allows direct integration into 3.3V, 5V, and 12V systems without level-shifting |
| Turn-On/Off Time | 25ns / 15ns typical - enables high-speed multiplexing in automated test equipment and digital I/O expansion |
Pinout & Package
MAX4066ACSD+T is housed in a 14-pin narrow SO (SOIC-14) package, 3.9mm × 8.7mm body, 1.27mm pitch, compliant with JEDEC MS-012. Pin 1 is marked by a beveled corner or dot; pin count and layout match industry-standard SO-14 footprints.
| 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 conduction |
| 2, 5, 10, 12 | COM1–COM4 | Common analog terminals - serve as shared signal paths for each switch; bidirectional and rail-to-rail capable |
| 6, 7, 12, 14 | IN1–IN4 | Logic control inputs - accept TTL/CMOS levels; active-high enables corresponding NO–COM path |
| 8 | GND | Analog/digital ground reference - must be low-impedance return for leakage-sensitive applications |
| 14 | V+ | Positive supply - powers internal switch circuitry and sets analog signal range (GND to V+) |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility with 74HC4066 | Direct PCB replacement in legacy designs without layout changes - same pinout and logic behavior |
| Guaranteed on-resistance flatness | ≤6Ω over full signal range - minimizes harmonic distortion and amplitude error in AC-coupled audio/video paths |
| Low crosstalk and off-isolation | -86dB crosstalk, -58dB off-isolation - prevents signal coupling between adjacent channels in dense multiplexer arrays |
| Single-supply rail-to-rail operation | Supports analog signals from GND to V+ - eliminates need for dual supplies in portable medical or measurement devices |
| ESD robustness | >2000V HBM - enhances reliability in manufacturing handling and end-equipment field environments |

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 |
|---|---|---|---|
| ADG408BRUZ | 8-channel, single-pole single-throw; higher on-resistance (100Ω typ at 5V); requires dual ±15V or single 5V supply | Designed for higher-channel-count multiplexing rather than discrete quad routing; less suitable for battery operation due to higher leakage (1nA) | Select when needing more than 4 channels in same footprint or operating from ±15V rails |
| TS5A23157DCKR | Lower voltage range (1.65V–5.5V); smaller 6-pin SC70 package; 0.9Ω on-resistance at 3.3V but only dual-channel | Optimized for space-constrained mobile I/O expansion; lacks quad configuration and 12V capability | Select for ultra-low-voltage, high-density PCBs where 12V operation and four independent switches are not required |
Compared with ADG408BRUZ and TS5A23157DCKR, the MAX4066ACSD+T uniquely balances 12V tolerance, quad SPST topology, sub-nA leakage, and SO-14 pin compatibility - making it optimal for industrial and portable systems requiring robust, drop-in-replacement analog switching at 3V/5V/12V.

FAQ
What is the maximum supply voltage rating for MAX4066ACSD+T?
The absolute maximum supply voltage for MAX4066ACSD+T is +17V, with recommended continuous operation from +2.0V to +16V. Operation beyond +16V risks permanent damage, and the device is fully specified at 3V, 5V, and 12V supply points per its electrical characteristics table. Always observe proper power sequencing - apply V+ before logic inputs - to avoid latch-up or overstress.
Does MAX4066ACSD+T support bidirectional analog signal flow?
Yes, MAX4066ACSD+T supports fully bidirectional analog signal flow between NO and COM terminals. Each SPST switch conducts equally in both directions when enabled, with identical on-resistance, capacitance, and leakage specifications regardless of signal polarity or direction - a core feature of its CMOS transmission-gate architecture.
Is MAX4066ACSD+T pin-compatible with the 74HC4066?
Yes, MAX4066ACSD+T is explicitly pin-compatible with the 74HC4066 in the SO-14 package. Pin assignments for IN1–IN4, NO1–NO4, COM1–COM4, V+, and GND match exactly, and logic-level thresholds (TTL/CMOS compatible) allow direct substitution without PCB modification or firmware changes.
What is the typical on-resistance flatness specification for MAX4066ACSD+T?
The typical on-resistance flatness for MAX4066ACSD+T is ≤6Ω over the full analog signal range (GND to V+), defined as the difference between maximum and minimum RON measured across all signal voltages. This tight flatness ensures consistent gain and minimal harmonic distortion in AC-coupled applications like audio routing and precision data acquisition.
Can MAX4066ACSD+T operate from a 3.3V supply?
Yes, MAX4066ACSD+T is fully operational from a 3.3V supply. At V+ = 3.3V, it delivers guaranteed on-resistance ≤170Ω, turn-on time ≤185ns, and off-leakage ≤1nA - meeting requirements for modern low-voltage embedded systems. Its 2.0V minimum supply enables use in deep-sleep battery modes where voltage sags below 3.0V.
