Product details
Overview
MAX4066EPD from Maxim Integrated is a quad, single-pole single-throw (SPST), CMOS analog switch designed for low-voltage signal routing in precision and battery-powered systems. It operates from +2.0V to +16V, delivers 45Ω on-resistance at 12V, achieves 4Ω channel-to-channel on-resistance matching, and supports bidirectional analog signals from GND to V+. It is commonly used in audio routing, data-acquisition front-ends, and sample-and-hold circuits.
For engineers reviewing the MAX4066EPD datasheet, MAX4066EPD pinout, MAX4066EPD application, or MAX4066EPD equivalent, key selection criteria include guaranteed on-resistance flatness (≤6Ω), ultra-low off-leakage (≤1nA at +25°C), TTL/CMOS-compatible control inputs, -58dB off-isolation at 1MHz, and compatibility with 14-pin plastic DIP packaging for through-hole prototyping and industrial designs.
Technical Context
The MAX4066EPD implements a fully complementary CMOS transmission-gate architecture enabling rail-to-rail analog signal handling (GND to V+) with minimal distortion (0.03% THD). Its four independent SPST switches are controlled by separate TTL/CMOS logic inputs (IN1–IN4), each driving one switch pair (COMx/NOx) without internal interconnects.
It features guaranteed dynamic performance across supply voltages: 100MHz on-channel bandwidth at 5V, ≤125ns turn-on time at 3V, and <10pC charge injection - critical for precision sampling and low-crosstalk multiplexing in mixed-signal systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 45Ω max at V+ = 12V - ensures minimal signal attenuation and gain error in sensor/ADC interfaces |
| On-Resistance Match (∆RON) | 4Ω max - enables matched gain paths in differential or multi-channel instrumentation |
| Off-Leakage Current | 1nA max at +25°C - preserves accuracy in high-impedance sample-and-hold and battery-monitoring nodes |
| Bandwidth | >100MHz - supports video, fast DAC output switching, and wideband communication signal routing |
| Off Isolation | -58dB at 1MHz - suppresses crosstalk between inactive channels in dense multiplexer layouts |
| Supply Range | +2.0V to +16V - allows direct integration with 3.3V, 5V, and 12V system rails without level-shifting |
| Logic Compatibility | TTL/CMOS input thresholds - simplifies interface with microcontrollers, FPGAs, and legacy logic families |
Pinout & Package
MAX4066EPD is supplied in a 14-pin plastic DIP package (0.300" width), rated for -40°C to +85°C operation. Pin 1 is NO1; pin 2 is COM1; pin 4 is NO2; pin 5 is COM2; pin 9 is NO3; pin 10 is COM3; pin 13 is NO4; pin 12 is COM4; pin 6 is IN1; pin 7 is IN2; pin 14 is IN3; pin 15 is IN4; pin 8 is GND; pin 16 is V+ - but only 14 pins are present in DIP; pins 15 and 16 are omitted per DIP pinout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 13 | NO1–NO4 (Normally Open) | Bidirectional analog output terminal; open-circuit when switch is OFF; connects to COMx when ON |
| 2, 5, 10, 12 | COM1–COM4 (Common) | Bidirectional analog input/output node; carries signal when corresponding NOx is closed |
| 6, 7, 14, 15* | IN1–IN4 (Control Inputs) | Active-HIGH TTL/CMOS logic inputs; drive respective switches ON at VINH ≥ 2.4V (for 5V) or ≥ 4.0V (for 12V) |
| 8 | GND | Analog and digital ground reference; must be low-impedance for leakage and noise control |
| 16* | V+ | Positive supply rail; powers analog switch core and level-shifters; supports up to +16V |
*Pins 15 and 16 are not present in the 14-pin DIP package (MAX4066EPD); pin numbering follows SO/QSOP layout convention but maps to physical DIP pins 1–14 only.

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 rated for 0°C to +70°C industrial range vs. -40°C to +85°C of MAX4066EPD | Limited to commercial-temperature environments; unsuitable for automotive or extended-temperature industrial use | Select MAX4066CPD only if ambient operating temperature stays within 0°C–70°C and cost is prioritized over thermal margin |
| ADG451BRZ | 44Ω RON at 12V, but higher 20nA max off-leakage at +25°C and no guaranteed 3V operation | Less suitable for ultra-low-leakage sample-and-hold or battery-critical designs; requires ≥15V supply for full spec compliance | Choose ADG451BRZ only when existing PCB uses SO-16 footprint and leakage >1nA is acceptable |
Compared with MAX4066CPD, MAX4066EPD offers extended temperature reliability; compared with ADG451BRZ, it provides superior leakage performance and guaranteed 3V functionality - making MAX4066EPD optimal for precision, low-power, and wide-temperature applications where signal integrity and supply flexibility are critical.

FAQ
What is the maximum supply voltage rating for MAX4066EPD?
The absolute maximum supply voltage for MAX4066EPD is +17V, with recommended continuous operation from +2.0V to +16V. Exceeding +17V risks permanent damage. The device is fully specified at 3V, 5V, and 12V supplies, and its on-resistance degrades predictably above 12V - e.g., ~52Ω at 15V per typical curves. Always observe proper power sequencing: apply V+ before logic inputs.
Does MAX4066EPD support bidirectional analog signal flow?
Yes, MAX4066EPD supports fully bidirectional analog signal flow between COMx and NOx terminals. Each SPST switch conducts equally well in either direction, with identical on-resistance and leakage specifications regardless of signal polarity or direction - enabling flexible use in both input and output signal routing paths without redesign.
What is the guaranteed on-resistance matching between channels for MAX4066EPD?
MAX4066EPD guarantees ≤4Ω on-resistance matching (∆RON = RONmax − RONmin) between any two channels at V+ = 12V and TA = +25°C. This specification holds across the full operating temperature range (-40°C to +85°C) and ensures consistent gain scaling in multi-channel instrumentation, such as simultaneous-sampling data loggers or balanced audio routing.
Can MAX4066EPD operate from a 3V supply, and what are the key limitations?
Yes, MAX4066EPD is fully specified down to +2.0V and operates reliably at 3V. At 3V, on-resistance increases to 170Ω max, turn-on time extends to 185ns max, and off-leakage remains ≤1nA. These trade-offs are documented in the +3V Electrical Characteristics table and are acceptable for low-speed, low-bandwidth applications like sensor multiplexing or battery-status monitoring.
Is MAX4066EPD pin-compatible with industry-standard logic devices?
MAX4066EPD is pin-compatible with the 74HC4066 in the 14-pin DIP package, sharing identical pin assignments for NOx, COMx, INx, V+, and GND. However, unlike the 74HC4066, MAX4066EPD offers guaranteed 3V operation, lower on-resistance (45Ω vs. ~120Ω), tighter channel matching, and enhanced ESD protection (>2000V vs. ~200V), making it a functional upgrade without PCB changes.
