Product details
Overview
MAX4066ACSD+ 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 grade), and 100pA COM off-leakage at +25°C. It operates as a bilateral signal routing device in battery-powered instrumentation and audio path switching.
For engineers reviewing the MAX4066ACSD+ datasheet, MAX4066ACSD+ pinout, MAX4066ACSD+ application, or MAX4066ACSD+ equivalent, key selection criteria include guaranteed on-resistance flatness (≤6Ω), low THD (0.03%), high off-isolation (−58dB), and TTL/CMOS-compatible control logic across industrial temperature range (0°C to +70°C).
Technical Context
The MAX4066ACSD+ implements fully complementary CMOS transmission-gate architecture with matched P- and N-channel devices per channel, enabling rail-to-rail analog signal handling (0V to V+) and bidirectional conduction. Its logic interface accepts standard TTL/CMOS voltage thresholds (VINH = 4.0V min at V+ = 12V; VINL = 0.8V max) without level-shifting.
Designed for signal integrity in multiplexed paths, it delivers >100MHz on-channel bandwidth, −86dB crosstalk between adjacent channels, and <10pC charge injection-critical for sample-and-hold and precision data-acquisition systems where settling error and glitch energy must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 45Ω max at V+ = 12V - ensures minimal signal attenuation and gain error in sensor/ADC front-ends |
| On-Resistance Match (∆RON) | 2Ω max - guarantees consistent gain and phase response across all four channels in differential or multi-path routing |
| COM Off-Leakage Current | 100pA max at +25°C - preserves accuracy in high-impedance sample-and-hold and battery-monitoring circuits |
| Off Isolation | −58dB at 1MHz - suppresses unwanted coupling between inactive and active signal paths |
| THD | 0.03% at 1kHz - supports low-distortion audio and precision analog signal switching |
| Supply Range | +2.0V to +16V single supply - enables direct integration into 3.3V, 5V, and 12V systems without auxiliary rails |
| Bandwidth | >100MHz - supports fast digital signals and video-frequency analog routing without roll-off |
Pinout & Package
MAX4066ACSD+ is housed in a 14-pin narrow SO (Small Outline) package, 150-mil body width, with standard JEDEC MS-012AC footprint (5.00mm × 4.40mm, 1.75mm height). Pin 1 is marked by notch or dot; pin count and spacing comply with RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 13 | NO1–NO4 (Normally Open) | Bidirectional analog output terminals; open-circuit when INx = L; connect to COMx when INx = H |
| 2, 5, 10, 12 | COM1–COM4 (Common) | Bidirectional analog input/output nodes; routed to corresponding NOx when switch enabled |
| 6, 7, 12, 14 | IN1–IN4 (Control Inputs) | TTL/CMOS-compatible digital inputs; high = ON, low = OFF; no internal pull-ups/downs |
| 8 | GND | Analog/digital ground reference; must be low-impedance return path for leakage and switching currents |
| 14 | V+ | Positive supply rail; powers analog switches and logic interface; supports 2.0V–16V operation |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility with 74HC4066 | Direct drop-in replacement in legacy designs using 14-pin DIP/SO footprints and identical logic mapping |
| Guaranteed on-resistance flatness | ≤6Ω over full signal range (0V to V+) - maintains linear gain across entire analog input span |
| Low charge injection | ≤10pC - minimizes voltage glitch on sampled capacitors, reducing hold-mode settling time |
| ESD robustness | >2000V per Method 3015.7 - withstands handling and board-level ESD events without latch-up or parameter shift |

Applications
| Battery-Operated Instrumentation | Audio Signal Routing |
|---|---|
Use Scenario: Multiplexing sensor outputs (thermocouples, RTDs) into a shared ADC channel in portable data loggers. IC Role / Device Role / Timing Role: Quad SPST analog switch providing channel-selectable, low-leakage, rail-to-rail signal path with minimal offset error. Use Value: 100pA off-leakage prevents drift in high-Z sensor bridges; 45Ω RON avoids gain compression at 12-bit+ resolution. |

IC Role / Device Role / Timing Role: Low-THD (0.03%), wide-bandwidth (>100MHz) analog switch enabling transparent source switching without audible artifacts. Use Value: −86dB crosstalk eliminates bleed between channels; bidirectional operation supports both input and output routing. |
| Low-Voltage Data Acquisition | Sample-and-Hold Circuits |
Use Scenario: Front-end multiplexer in 3.3V microcontroller-based DAQ systems measuring 0–3.3V sensor signals. IC Role / Device Role / Timing Role: Quad SPST switch operating down to +2.0V supply, delivering 170Ω RON at 3V while maintaining TTL-compatible control. Use Value: Guaranteed 3V performance enables direct interfacing with low-power MCUs; 2Ω channel match ensures uniform channel calibration. |
Use Scenario: Sampling capacitor charging path in precision S/H amplifiers used in spectroscopy and oscilloscope front-ends. IC Role / Device Role / Timing Role: Low-charge-injection (≤10pC), low-RON switch minimizing droop and settling error during acquisition phase. Use Value: Predictable 10pC injection allows accurate compensation; 45Ω RON limits RC time constant with typical 10–100pF hold capacitors. |
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, 3.5Ω RON at 5V; requires dual ±15V or single 5V supply; not rated below 4.5V | Better channel count and lower RON, but lacks 2.0V operation and 100pA leakage spec | Select when higher channel density and lower on-resistance outweigh low-voltage support and ultra-low leakage needs |
| TS5A23157DGSR | Single-supply 1.65–5.5V; 0.9Ω RON at 3.3V; 1nA leakage at 25°C; 10-pin VSSOP | Lower RON and smaller package, but only dual-channel; no 14-pin SO variant or 12V rating | Select for space-constrained 3.3V systems where quad functionality is split across two dual-switch ICs |
Compared with ADG408BRUZ and TS5A23157DGSR, the MAX4066ACSD+ uniquely balances ultra-low leakage (100pA), wide supply range (2.0–16V), and pin-compatible 14-pin SO packaging-making it optimal for legacy-replacement and battery-operated designs requiring guaranteed performance across voltage and temperature extremes.

FAQ
What is the maximum supply voltage rating for MAX4066ACSD+?
The absolute maximum rating for V+ is +17V, but the device is fully specified for reliable operation from +2.0V to +16V. Operation at 16V is supported across the full 0°C to +70°C temperature range, with guaranteed parameters including 45Ω on-resistance and 2Ω channel matching. Exceeding +17V risks permanent damage per Absolute Maximum Ratings.
Does MAX4066ACSD+ support rail-to-rail analog signal switching?
Yes, MAX4066ACSD+ supports rail-to-rail analog signal handling from 0V to V+. The analog signal range is explicitly specified as VCOM/VNO = 0V to V+ in the Electrical Characteristics tables, and internal ESD clamps are designed to protect against overvoltage without affecting normal operation within this range.
Is MAX4066ACSD+ pin-compatible with the standard 74HC4066?
Yes, MAX4066ACSD+ is explicitly advertised as pin-compatible with 74HC4066 in the Features section and shares identical pin functions (IN1–IN4, COM1–COM4, NO1–NO4, V+, GND) and 14-pin SO footprint. No PCB layout changes are required for drop-in replacement, though users should verify timing and leakage requirements meet system specs.
What is the typical charge injection value for MAX4066ACSD+ and why does it matter?
Charge injection is guaranteed ≤10pC (typical 2pC) per switch transition. This matters because injected charge displaces voltage on sampling capacitors in data-acquisition and sample-and-hold circuits, causing hold-mode errors and extended settling time. Low charge injection enables faster, more accurate sampling without complex compensation networks.
Can MAX4066ACSD+ operate from a 3.0V supply, and what are the key performance trade-offs?
Yes, MAX4066ACSD+ is fully specified at 3.0V: on-resistance rises to 170Ω max, turn-on time increases to 185ns max, and leakage remains ≤1nA. These trade-offs reflect MOSFET threshold limitations at low VGS but are guaranteed-making it viable for 3.3V/3.0V MCU interfaces where ultra-low power and small size outweigh RON sensitivity.
