Product details
Overview
MAX4066ESD from Maxim Integrated is a quad, single-pole single-throw (SPST), CMOS analog switch designed for low-voltage signal routing in battery-powered and precision audio systems. It operates from +2.0V to +16V, delivers 45Ω on-resistance at 12V, 2Ω channel-to-channel matching (MAX4066A variant), and supports bidirectional analog signals up to V+ with TTL/CMOS-compatible control inputs.
For engineers reviewing the MAX4066ESD datasheet, MAX4066ESD pinout, MAX4066ESD application, or MAX4066ESD equivalent, key selection criteria include guaranteed on-resistance flatness (≤6Ω), ultra-low off-leakage (100pA at +25°C), ESD robustness (>2000V per Method 3015.7), and compatibility with 14-pin narrow SO packaging for space-constrained PCB layouts.
Technical Context
The MAX4066ESD implements a fully complementary CMOS transmission-gate architecture enabling rail-to-rail analog signal handling (0V to V+) with minimal distortion (0.03% THD) and high bandwidth (>100MHz). Its four independent SPST switches share a common V+ supply and ground, each controlled by dedicated TTL/CMOS logic inputs (IN1–IN4).
It features matched on-resistance across channels (2Ω max for MAX4066A), low charge injection (2–10pC), and tightly specified dynamic parameters including turn-on time (25–125ns) and off-isolation (−58dB), making it suitable for sample-and-hold circuits and low-distortion audio switching where timing skew and signal integrity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.0V to +16V - Enables operation from single-cell Li-ion (3.0V) up to industrial 12V rails without level-shifting. |
| On-Resistance (RON) | 45Ω max at 12V - Ensures <1% gain error in 1kΩ impedance signal paths; flatness ≤6Ω preserves linearity across signal range. |
| Channel Matching (∆RON) | 2Ω max (MAX4066A) - Minimizes amplitude mismatch in multi-channel routing or differential pair switching. |
| Off-Leakage Current | 100pA at +25°C - Critical for maintaining accuracy in high-impedance sensor interfaces and battery-operated data acquisition. |
| Bandwidth | >100MHz - Supports video signal routing and fast digital waveform switching without attenuation. |
| ESD Rating | >2000V per Method 3015.7 - Provides robust handling during assembly and field use without external protection. |
| THD | 0.03% - Meets fidelity requirements for line-level audio signal path switching without audible artifacts. |
Pinout & Package
MAX4066ESD is packaged in a 14-pin narrow SO (Small Outline) surface-mount package (JEDEC MS-012AC), footprint-compatible with industry-standard 14-pin SOIC but with reduced width (3.9mm body width). Pin pitch is 1.27mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 13 | NO1–NO4 (Normally Open) | Analog output terminals; open-circuit when switch is OFF; connect to COM when ON - bidirectional signal path. |
| 2, 5, 10, 12 | COM1–COM4 (Common) | Analog input/output ports shared with NO pins - serves as signal entry/exit point for each SPST switch. |
| 6, 7, 14, 15 | IN1–IN4 (Logic Inputs) | TTL/CMOS-compatible digital controls; HIGH = ON state, LOW = OFF - no external pull-ups required. |
| 8 | GND | Ground reference for analog and digital sections - must be low-impedance connection to minimize noise coupling. |
| 16 | V+ | Positive supply for analog and logic sections - powers internal CMOS gates and defines analog signal range (0V to V+). |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility with 74HC4066 | Direct drop-in replacement for legacy designs using 74HC4066 in 14-pin SO/DIP footprints - no layout change needed. |
| Guaranteed on-resistance flatness | ≤6Ω over full signal range (0V to V+) - maintains consistent gain and minimal harmonic distortion in AC-coupled paths. |
| Ultra-low off-leakage current | 100pA (MAX4066A) at +25°C - prevents voltage droop in high-Z sample-and-hold capacitors and extends battery life. |
| Bidirectional signal handling | V+ to GND analog range - eliminates need for dual-supply design in single-ended systems like portable audio codecs. |
| Low crosstalk and isolation | −86dB crosstalk, −58dB off-isolation - prevents interference between adjacent switched channels in multi-signal routing applications. |
Applications
| Audio Signal Routing | Portable Data Acquisition |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4066CPD | Same electrical specs, but in 14-pin plastic DIP package - larger footprint, through-hole mounting. | Suitable for prototyping or legacy through-hole assemblies; lacks SO's thermal performance and board density. | Select MAX4066CPD only when DIP form factor or hand-soldering is required; MAX4066ESD preferred for automated SMT production. |
| ADG1414BRUZ | Quad SPST, 1.5Ω RON (at ±15V), but requires dual ±15V supplies; higher cost; 16-pin TSSOP. | Used in high-precision instrumentation needing sub-ohm RON; incompatible with single-supply +3V/+5V systems. | Choose ADG1414BRUZ only when <2Ω RON and dual-supply operation are mandatory; MAX4066ESD offers better cost/performance for single-supply portable designs. |
Compared with MAX4066CPD, MAX4066ESD provides identical analog performance in a smaller, surface-mount package optimized for volume manufacturing; compared with ADG1414BRUZ, it trades lower on-resistance for single-supply simplicity, lower cost, and broader voltage flexibility - ideal for battery-powered and consumer-grade signal routing.

FAQ
What is the operating temperature range for MAX4066ESD?
The MAX4066ESD is rated for operation from −40°C to +85°C. This extended industrial temperature range ensures reliable performance in automotive cabin modules, outdoor sensor nodes, and portable medical devices where ambient conditions vary widely. The "E" grade suffix explicitly denotes this temperature capability, distinct from the "C" grade (0°C to +70°C) versions like MAX4066CPD.
Does MAX4066ESD support rail-to-rail analog signal switching?
Yes, MAX4066ESD supports rail-to-rail analog signal switching from GND to V+. When V+ = 5V, the device passes signals from 0V to 5V without clipping or distortion - a key advantage over older analog switches limited to V+ −1.5V. This capability eliminates the need for level-shifting circuitry in single-supply systems such as USB-powered audio interfaces.
Is MAX4066ESD pin-compatible with the 74HC4066?
Yes, MAX4066ESD is pin-compatible with the 74HC4066 in the 14-pin narrow SO package. Pin assignments for IN1–IN4, COM1–COM4, NO1–NO4, V+, and GND match exactly, allowing direct substitution in existing layouts. However, MAX4066ESD improves on 74HC4066 with lower on-resistance (45Ω vs. ~120Ω), tighter channel matching, and superior leakage specs.
What is the maximum analog signal frequency supported by MAX4066ESD?
MAX4066ESD supports analog signals up to >100MHz, as confirmed by its on-channel bandwidth specification. At 1MHz, it delivers −3dB response with 50Ω source/load; at 10MHz, insertion loss remains below 0.5dB. This makes it suitable not only for audio but also for composite video routing and high-speed digital waveform gating in test equipment.
How does the ESD protection of MAX4066ESD compare to standard HBM ratings?
MAX4066ESD provides >2000V ESD protection per Method 3015.7 (a system-level test), exceeding typical Human Body Model (HBM) ratings of 2kV. This robustness is achieved via integrated protection diodes and layout hardening, reducing the need for external TVS components in final product designs - particularly valuable in handheld devices exposed to frequent handling.
