Product details
Overview
The 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, achieves ≤2Ω channel-to-channel on-resistance matching (MAX4066A variant), supports ±0.3V to V+ +0.3V analog signal range, and features 100pA max COM off-leakage at +25°C - enabling high-fidelity audio switching and low-power data acquisition.
For engineers reviewing the MAX4066CPD+ datasheet, MAX4066CPD+ pinout, MAX4066CPD+ application, or MAX4066CPD+ equivalent, key selection criteria include guaranteed 45Ω on-resistance at 12V, 2Ω channel matching, 100pA leakage (MAX4066A), TTL/CMOS-compatible control inputs, and DIP-14 package compatibility with legacy 74HC4066 layouts.
Technical Context
The MAX4066CPD+ implements a fully complementary CMOS transmission-gate architecture optimized for bilateral analog signal conduction across four independent SPST switches. Its design ensures symmetrical on-resistance over the full analog signal range (0V to V+) and maintains tight channel matching (≤2Ω) through matched transistor sizing and layout techniques.
It integrates ESD protection >2000V (HBM), supports single-supply operation without negative rails, and uses logic-level inputs that interface directly with 3V/5V microcontrollers. The device's low charge injection (≤10pC) and flat on-resistance (≤6Ω) preserve signal integrity in sample-and-hold and multiplexed ADC front-ends.
Key Specifications

| Bandwidth | >100MHz - preserves fidelity of fast-switching signals and video-frequency analog waveforms |
| THD | 0.03% - meets requirements for low-distortion audio signal routing and professional line-level switching |
| Crosstalk | -86dB - prevents interference between adjacent switched channels in dense multiplexer designs |
Pinout & Package
MAX4066CPD+ is housed in a 14-pin plastic DIP (dual in-line package) with 0.300-inch body width, compatible with standard through-hole PCB assembly and socketing. Pin 1 is located at the left end of the top row when viewing the top side with the notch or dot oriented left.

| 2, 5, 10, 12 | COM1–COM4 (Common) | Bidirectional analog input terminals - accept source signals and route them to corresponding NO pins |
| 6, 7, 12, 14 | IN1–IN4 (Control Inputs) | TTL/CMOS-compatible digital inputs - high = ON state, low = OFF state for respective switch |
| 8 | GND | Analog/digital ground reference - must be connected to system ground plane for leakage and noise control |
| 14 | V+ | Positive supply rail - powers internal CMOS switches and logic; sets analog signal range (0V to V+) |

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 |
|---|---|---|---|
| MAX4066ACPD+ | Same pinout and electrical specs; C-grade (0°C to +70°C) with identical performance - differs only in marking and traceability documentation | No functional difference; used interchangeably in commercial-grade designs where full Maxim traceability is not required | Select MAX4066ACPD+ for cost-sensitive production where full Maxim factory traceability is unnecessary |
| ADG408BRUZ | 8-channel single-pole single-throw (SPST) switch; higher on-resistance (100Ω typ at 5V); requires dual ±15V or single 5V supply | Better suited for high-channel-count multiplexing but less optimal for low-leakage, low-voltage battery operation | Choose ADG408BRUZ only when expanding beyond 4 channels or requiring industry-standard 16-pin TSSOP footprint |
Compared with MAX4066CPD+, MAX4066ACPD+ offers identical functionality with simplified logistics, while ADG408BRUZ trades lower leakage and wider supply range for higher channel density - making MAX4066CPD+ the optimal choice for compact, low-power, precision quad-switching applications.

FAQ
What is the maximum supply voltage rating for the MAX4066CPD+?
The MAX4066CPD+ has an absolute maximum supply voltage (V+) of +17V, with recommended continuous operation from +2.0V to +16V. Operation above +16V risks permanent damage, and the device is fully specified at 3V, 5V, and 12V supply levels per its datasheet characterization.
Does the MAX4066CPD+ support bidirectional analog signal flow?
Yes, the MAX4066CPD+ supports fully bidirectional analog signal routing between COM and NO terminals. Its CMOS transmission-gate structure imposes no polarity constraints, allowing signals to pass equally well from COM to NO or NO to COM within the rated analog signal range (0V to V+).
Is the MAX4066CPD+ pin-compatible with the 74HC4066?
Yes, the MAX4066CPD+ is explicitly designed as a pin-compatible upgrade to the 74HC4066. It occupies the same 14-pin DIP footprint, matches pin functions (IN1–IN4, COM1–COM4, NO1–NO4, V+, GND), and accepts identical TTL/CMOS logic levels - enabling direct replacement without PCB modification.
What is the typical on-resistance flatness specification for the MAX4066CPD+?
The MAX4066CPD+ guarantees ≤6Ω on-resistance flatness (RFLAT(ON)) over its full analog signal range at +25°C and 12V supply. This means the variation in on-resistance across the 0V to V+ signal swing remains within 6Ω - critical for minimizing harmonic distortion in audio and precision measurement paths.
Can the MAX4066CPD+ operate from a 3V supply, and what is its on-resistance at that voltage?
Yes, the MAX4066CPD+ is fully specified at +3V supply, with a maximum on-resistance of 170Ω. This value is guaranteed across the full operating temperature range (0°C to +70°C), ensuring reliable switching performance in modern low-voltage microcontroller-based systems and energy-harvesting applications.
