Product details
Overview
MAX4066CPD 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 MAX4066CPD datasheet, MAX4066CPD pinout, MAX4066CPD application, or MAX4066CPD equivalent, key selection criteria include guaranteed on-resistance flatness (≤6Ω), sub-1nA off-leakage at +25°C, low distortion (0.03%), wide bandwidth (>100MHz), and compatibility with 74HC4066-based layouts in 14-pin DIP packages.
Technical Context
The MAX4066CPD implements a fully complementary CMOS transmission-gate architecture enabling rail-to-rail analog signal handling (0V to V+) and bilateral switching without polarity constraints. Its logic interface accepts standard TTL/CMOS voltage thresholds (VINH = 4.0V min at V+ = 12V; VINL = 0.8V max), eliminating level-shifting requirements in mixed-supply systems.
It features matched on-resistance across all four channels (ΔRON ≤ 4Ω at 12V), low charge injection (≤10pC), and high dynamic performance: 100MHz on-channel bandwidth, −86dB crosstalk, and −58dB off-isolation at 1MHz - critical for multiplexed data acquisition and low-noise audio routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2.0V to +16V single supply - enables direct integration into 3V, 5V, and 12V systems without auxiliary rails |
| On-Resistance (12V) | 45Ω max - ensures minimal signal attenuation and voltage drop in sensor/ADC front-end paths |
| Channel Matching (ΔRON) | 4Ω max - preserves gain/phase balance in differential or multi-channel signal paths |
| Off-Leakage Current | 1nA max at +25°C - prevents DC error accumulation in sample-and-hold and high-impedance sensor interfaces |
| Bandwidth | >100MHz - supports video, fast data acquisition, and broadband communication signal routing |
| THD | 0.03% - maintains fidelity in line-level and headphone audio switching applications |
| ESD Rating | >2000V HBM - provides robust handling during PCB assembly and field operation |
Pinout & Package
MAX4066CPD is housed in a 14-pin plastic DIP package (0.300" width) with through-hole mounting. Pin 1 is top-left corner when notch faces upward; pin numbering proceeds counter-clockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 13 | NO1–NO4 | Normally open analog terminals - connect to signal sources when switch is enabled; isolated otherwise |
| 2, 5, 10, 12 | COM1–COM4 | Common bidirectional analog ports - serve as input/output junctions for each SPST path |
| 6, 7, 12, 14 | IN1–IN4 | TTL/CMOS logic control inputs - high = ON state (closed), low = OFF state (open) |
| 8 | GND | Analog/digital ground reference - must be low-impedance return for leakage-sensitive circuits |
| 14 | V+ | Positive supply rail - powers internal CMOS switches and defines analog signal range (0V to V+) |
Key Features
| Feature | Design Value |
|---|---|
| PIN-COMPATIBLE WITH 74HC4066 | Direct drop-in replacement in legacy 14-pin DIP layouts - no PCB redesign required |
| GUARANTEED ON-RESISTANCE | 170Ω max at 3V, 45Ω max at 12V - ensures predictable insertion loss across operating voltages |
| LOW LEAKAGE CURRENT | 1nA max COM/NO off-leakage at +25°C - avoids drift in µA-range sensor or integrator circuits |
| LOW DISTORTION & HIGH BANDWIDTH | 0.03% THD and >100MHz bandwidth - suitable for audio, video, and RF-adjacent signal routing |
| V+ TO GND SIGNAL HANDLING | Rail-to-rail analog range - eliminates need for dual supplies in unipolar signal chains |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4066ACPD | Same pinout and electrical specs; 'A' suffix denotes improved channel matching (2Ω vs. 4Ω) and lower leakage (100pA vs. 1nA) | Better suited for high-precision, low-leakage applications like medical instrumentation or metrology | Select MAX4066ACPD when sub-nA leakage or tighter ΔRON is required; otherwise MAX4066CPD offers cost-optimized performance. |
| ADG408BRUZ | 8-channel, 3.5Ω typical on-resistance at 5V; requires 5V logic control; not pin-compatible | Higher channel count but incompatible footprint - demands PCB redesign and layout validation | Choose ADG408BRUZ only when expanding to 8 channels justifies re-spin; MAX4066CPD remains optimal for quad-channel space-constrained designs. |
Compared with MAX4066ACPD, the MAX4066CPD trades minor leakage and matching performance for cost efficiency while retaining identical pinout and system integration. Against ADG408BRUZ, it offers proven 14-pin DIP compatibility and broader supply flexibility (2V–16V vs. 4.5V–20V), avoiding layout risk in legacy or volume-sensitive designs.

FAQ
What is the operating temperature range for MAX4066CPD?
The MAX4066CPD is rated for operation from 0°C to +70°C. This commercial-grade temperature range aligns with standard industrial and consumer equipment requirements. The 'C' suffix explicitly denotes this grade, distinguishing it from extended-range variants like MAX4066E_ _ (−40°C to +85°C) or MAX4066MJD (−55°C to +125°C). Thermal derating applies above +70°C per the datasheet's power dissipation curves.
Is MAX4066CPD pin-compatible with the 74HC4066?
Yes, MAX4066CPD is explicitly designed as a pin-compatible upgrade to the 74HC4066 in 14-pin DIP packages. Pin assignments for IN1–IN4, NO1–NO4, COM1–COM4, V+, and GND match identically. This allows direct substitution without PCB modification, while delivering superior specs: lower on-resistance (45Ω vs. ~120Ω), tighter channel matching, and enhanced ESD protection (>2000V vs. ~200V).
What is the maximum analog signal voltage supported by MAX4066CPD?
The MAX4066CPD supports analog signals from 0V to V+ (rail-to-rail), with absolute maximum ratings allowing VNO and VCOM to reach (V+ + 0.3V). For example, at V+ = 5V, the usable analog range is 0V to 5V. Exceeding V+ risks forward-biasing internal clamping diodes; the datasheet recommends sequencing V+ before logic inputs or adding external blocking diodes if overvoltage conditions are possible.
Does MAX4066CPD support bidirectional signal flow?
Yes, MAX4066CPD is a fully bidirectional analog switch. Each SPST channel (COM–NO) passes signals equally well in either direction, with identical on-resistance, leakage, and bandwidth characteristics regardless of signal polarity or current direction. This enables flexible use in multiplexer/demultiplexer configurations and AC-coupled audio paths where signal origin is undefined.
What is the typical power consumption of MAX4066CPD?
The MAX4066CPD consumes only 0.5µW typical quiescent power - derived from 1µA supply current at 0.5V effective voltage drop. Even under full operation (all channels ON/OFF), supply current remains ≤1µA across temperature. This ultra-low power draw makes MAX4066CPD ideal for always-on battery-powered nodes, extending operational life without compromising switching speed or signal integrity.
