Product details
Overview
MAX4066ESD+ 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 off-leakage at +25°C. It operates as a bilateral signal switch in audio routing, battery-powered data acquisition, and sample-and-hold circuits.
For engineers reviewing the MAX4066ESD+ datasheet, MAX4066ESD+ pinout, MAX4066ESD+ application, or MAX4066ESD+ equivalent, key selection criteria include guaranteed on-resistance flatness (≤6Ω), TTL/CMOS-compatible control inputs, −86dB crosstalk, 0.03% THD, and ESD robustness (>2000V per Method 3015.7).
Technical Context
The MAX4066ESD+ implements four independent SPST switches using complementary CMOS transistor pairs, enabling bidirectional analog signal conduction with rail-to-rail voltage handling (GND to V+). Its architecture guarantees matched on-resistance across channels and low charge injection (≤10pC) for precision sampling.
Control logic accepts TTL- or CMOS-level inputs (VINH ≥ 2.4V at 5V supply; VINL ≤ 0.8V), supporting direct interfacing with microcontrollers and FPGAs without level-shifting. Signal bandwidth exceeds 100MHz, and off-isolation reaches −58dB at 1MHz - critical for high-fidelity audio and low-noise measurement paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 45Ω max at V+ = 12V - ensures minimal signal attenuation and voltage drop in precision analog paths |
| Channel Matching (∆RON) | 2Ω max (MAX4066A) - enables accurate differential or ratiometric measurements across switched channels |
| Off-Leakage Current | 100pA max at +25°C - preserves integrity of high-impedance sensor nodes and battery runtime |
| Bandwidth | >100MHz - supports video, fast ADC/DAC interfaces, and broadband communication signals |
| Crosstalk | −86dB at 1MHz - prevents coupling between adjacent switched signal paths in dense routing |
| THD | 0.03% - maintains fidelity in low-distortion audio switching applications |
| ESD Rating | >2000V per Method 3015.7 - provides robust handling during board assembly and field operation |
Pinout & Package
MAX4066ESD+ is supplied in a 14-pin narrow SO (Small Outline) package, 150-mil body width, with standard JEDEC MS-012AC footprint and gull-wing leads. Pin 1 is marked by a beveled corner or dot; thermal pad is not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2, 5, 10, 12 | COM1–COM4 (Common) | Bidirectional analog input terminals - source or sink signal depending on configuration |
| 6, 7, 13, 14 | IN1–IN4 (Control Inputs) | TTL/CMOS-compatible digital inputs - high = ON, low = OFF for respective switch |
| 8 | GND | Analog/digital reference ground - must be low-impedance and tied to system common |
| 14 | V+ | Positive supply rail - powers internal logic and switch transistors; range 2.0V to 16V |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed on-resistance flatness | ≤6Ω over full signal range (0V to V+) - minimizes gain error in variable-gain or multiplexed amplifier stages |
| Low charge injection | ≤10pC - reduces settling error and pedestal distortion in sample-and-hold and data-acquisition systems |
| Pin compatibility with 74HC4066 | Direct functional replacement in legacy designs - no PCB layout change required for drop-in upgrade |
| Rail-to-rail analog signal handling | VCOM/VNO = 0V to V+ - supports full-supply-range signal switching without clamping or distortion |
| Ultra-low power consumption | 0.5µW typical - extends battery life in portable instrumentation and IoT edge sensors |
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 |
|---|---|---|---|
| MAX4066CPD+ | Same electrical specs but in 14-pin plastic DIP package; higher thermal resistance (10.00mW/°C derating); no ESD rating specified beyond 2000V | Suitable for prototyping and through-hole PCBs; less suitable for space-constrained or high-reliability surface-mount production | Select MAX4066CPD+ only when DIP footprint and hand-soldering are required; MAX4066ESD+ preferred for automated SMT assembly. |
| ADG408BRUZ | 8-channel single-pole single-throw (not quad); 40Ω RON at 15V; 1nA leakage (vs. 100pA); −80dB crosstalk; different pinout and control logic (3-wire serial vs. parallel) | Requires redesign of control interface and PCB layout; better suited for higher channel count, lower leakage tolerance applications | Choose ADG408BRUZ only when 8-channel density outweighs need for ultra-low leakage and pin compatibility; not a drop-in replacement. |
Compared with MAX4066CPD+, MAX4066ESD+ offers superior manufacturability via SO package and verified ESD robustness; compared with ADG408BRUZ, it delivers tighter leakage and matching specs in a pin-compatible 4-channel form factor ideal for legacy 74HC4066 upgrades.

FAQ
What is the operating voltage range for MAX4066ESD+?
The MAX4066ESD+ operates from a single supply of +2.0V to +16V. It is fully specified at 3V, 5V, and 12V, with guaranteed performance including on-resistance, leakage, and timing across this entire range. The analog signal range spans from GND to V+, enabling rail-to-rail switching without external biasing.
Is MAX4066ESD+ pin-compatible with the 74HC4066?
Yes, MAX4066ESD+ is explicitly designed as a pin-compatible upgrade to the industry-standard 74HC4066. It shares identical pin assignments for all 14 pins in the narrow SO package, allowing direct replacement without PCB modification while delivering improved on-resistance, leakage, and ESD performance.
What is the maximum allowable analog signal voltage on MAX4066ESD+?
The MAX4066ESD+ supports analog signals from GND to V+ (i.e., rail-to-rail). For example, with V+ = 12V, the valid signal range is 0V to 12V. Signals exceeding V+ or dropping below GND are clamped by internal diodes - forward current must be limited to ≤30mA to avoid damage.
How does the MAX4066ESD+ differ from the MAX4066A variant?
The MAX4066ESD+ is the standard-grade MAX4066 (not MAX4066A). Key differences include higher channel matching (4Ω max vs. 2Ω for MAX4066A), higher off-leakage (1nA vs. 100pA), and qualification for 0°C to +70°C operation. The MAX4066ESD+ retains identical pinout, package, and core functionality.
Does MAX4066ESD+ support bidirectional signal flow?
Yes, MAX4066ESD+ is a fully bidirectional analog switch. Each COM–NO pair conducts equally well in either direction - the device imposes no polarity requirement on analog signals, making it suitable for AC-coupled audio, differential sensor interfaces, and multiplexer/demultiplexer topologies.
