Product details
Overview
MAX4066ACPD 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 grade), and supports bidirectional analog signals from GND to V+. It is commonly used in audio signal switching and low-distortion data-acquisition front-ends.
For engineers reviewing the MAX4066ACPD datasheet, MAX4066ACPD pinout, MAX4066ACPD application, or MAX4066ACPD equivalent, key selection criteria include guaranteed on-resistance flatness (≤6Ω), sub-100pA off-leakage at +25°C, TTL/CMOS-compatible control inputs, 100MHz bandwidth, and compatibility with 74HC4066 layouts in 14-pin DIP packages.
Technical Context
The MAX4066ACPD implements four independent SPST switches using complementary CMOS transistor pairs per channel, enabling rail-to-rail analog signal handling (GND to V+) with minimal distortion. Its logic interface accepts standard TTL/CMOS voltage thresholds (VINH ≥ 2.4V at V+ = 5V; VINL ≤ 0.8V), eliminating level-shifting requirements.
Designed for low-power operation, it draws only 0.5µW quiescent power and features <100pA COM and NO off-leakage at +25°C (MAX4066A variant). Channel matching (ΔRON ≤ 2Ω) and on-resistance flatness (RFLAT(ON) ≤ 6Ω) are fully specified across temperature and supply voltage, supporting precision multiplexing in sample-and-hold and sensor interface circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (12V) | 45Ω max - ensures minimal signal attenuation and gain error in precision DC-coupled paths |
| Channel Matching (ΔRON) | 2Ω max - enables accurate differential or ratiometric measurements across switched channels |
| Off-Leakage Current | 100pA max at +25°C - preserves accuracy in high-impedance sample-and-hold and sensor nodes |
| Bandwidth | >100MHz - supports video, fast ADC/DAC switching, and broadband communication signals |
| Supply Range | +2.0V to +16V - allows direct integration into 3V, 5V, and 12V systems without regulators |
| THD | 0.03% - maintains fidelity in low-distortion audio routing applications |
| Off Isolation | -58dB at 1MHz - suppresses crosstalk between inactive and active signal paths |
Pinout & Package
MAX4066ACPD is housed in a 14-pin plastic DIP package (0.300" wide) with through-hole mounting. Pin 1 is top-left corner when notch faces up; pin numbering proceeds counter-clockwise.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 13 | NO1–NO4 | Normally open analog terminals - connect to signal sources when switch is enabled |
| 2, 5, 10, 12 | COM1–COM4 | Common analog terminals - bidirectional I/O path shared with NO pins |
| 6, 7, 12, 14 | IN1–IN4 | TTL/CMOS logic inputs - high = ON state; low = OFF state for corresponding switch |
| 8 | GND | Analog/digital ground reference - must be low-impedance for leakage and noise control |
| 14 | V+ | Positive supply - powers analog core and logic interface; supports up to +16V |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility with 74HC4066 | Direct drop-in replacement in legacy 14-pin DIP layouts without PCB revision |
| Guaranteed on-resistance flatness | ≤6Ω over full signal range - minimizes harmonic distortion in AC-coupled audio paths |
| Low charge injection | ≤10pC - reduces voltage glitch and settling time in sample-and-hold and multiplexer applications |
| V+ to GND signal handling | Rail-to-rail analog swing - eliminates need for dual supplies in single-ended sensor interfaces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4066CPD | Higher 4Ω channel matching (vs. 2Ω), 1nA off-leakage (vs. 100pA) - less precise for high-Z or low-distortion use cases | Suitable for general-purpose switching where ultra-low leakage or tight matching is not required | Select MAX4066CPD only if cost sensitivity outweighs leakage/matching requirements |
| ADG1414BRUZ | Lower 1.5Ω on-resistance but requires ≥±4.5V dual supply or ≥9V single supply - incompatible with 3V-only systems | Better for high-speed, low-RON industrial DAQ; unsuitable for battery-powered 3V designs | Choose ADG1414BRUZ only when supply headroom permits ≥9V operation and RON < 2Ω is critical |
Compared with MAX4066CPD and ADG1414BRUZ, the MAX4066ACPD uniquely balances 2Ω matching, 100pA leakage, and +2.0V to +16V single-supply operation - making it optimal for space-constrained, battery-powered, and audio-grade signal routing where layout compatibility with 74HC4066 is retained.

FAQ
What is the maximum supply voltage rating for MAX4066ACPD?
The MAX4066ACPD has an absolute maximum V+ rating of +17V, with guaranteed functional operation from +2.0V to +16V. Operation beyond +16V risks permanent damage, and the device is fully characterized at 3V, 5V, and 12V supply levels. The MAX4066ACPD's internal ESD protection exceeds 2000V per Method 3015.7, but sustained overvoltage must be avoided via proper sequencing or external diode clamping.
Is MAX4066ACPD pin-compatible with the industry-standard 74HC4066?
Yes, the MAX4066ACPD 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. No PCB layout changes are needed, and the MAX4066ACPD improves on-resistance, leakage, and bandwidth while maintaining TTL/CMOS logic compatibility.
What is the typical on-resistance flatness of MAX4066ACPD over its signal range?
The MAX4066ACPD guarantees on-resistance flatness (RFLAT(ON)) of ≤6Ω over the full analog signal range (GND to V+) at +25°C and ≤6Ω across temperature when operated at 12V. This specification ensures consistent gain and minimal harmonic distortion across the entire input voltage swing - critical for audio and precision measurement applications.
Does MAX4066ACPD support rail-to-rail analog signal operation?
Yes, the MAX4066ACPD supports analog signal voltages from GND to V+ (VCOM/VNO = 0V to V+), enabling true rail-to-rail switching without external level-shifting circuitry. This capability is confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables, and applies across the full operating temperature range (0°C to +70°C for the 'C' grade).
What is the off-leakage current specification for MAX4066ACPD at room temperature?
The MAX4066ACPD ('A' variant) specifies a maximum off-leakage current of ±100pA at +25°C for both COM and NO terminals, as verified by 100% testing at hot temperature and correlation at room temperature. This ultra-low leakage supports high-impedance node integrity in sample-and-hold circuits, sensor front-ends, and battery-powered metering systems.
