Product details
Overview
MAX4066ACPD+ from Maxim Integrated is a quad, single-pole single-throw (SPST), CMOS analog switch optimized for low-voltage operation (2.0V to 16V), featuring 45Ω on-resistance at 12V, 2Ω channel-to-channel matching (MAX4066A grade), and 100pA off-leakage at +25°C. It serves as a bilateral signal routing device in precision data-acquisition and battery-powered audio systems.
For engineers reviewing the MAX4066ACPD+ datasheet, MAX4066ACPD+ pinout, MAX4066ACPD+ application, or MAX4066ACPD+ equivalent, key selection criteria include guaranteed on-resistance flatness (≤6Ω), TTL/CMOS-compatible control inputs, −86dB crosstalk, 100MHz bandwidth, and DIP-14 package compatibility with legacy 74HC4066 layouts.
Technical Context
The MAX4066ACPD+ implements four independent SPST switches using complementary CMOS transistor pairs, enabling bidirectional analog signal flow between COM and NO terminals. Its architecture guarantees monotonic on-resistance over the full 0V to V+ signal range and supports rail-to-rail analog voltage handling without external biasing.
Control logic accepts standard TTL/CMOS input thresholds (VINH = 4.0V min at V+ = 12V; VINL = 0.8V max), and internal ESD protection exceeds 2000V per Method 3015.7. The device operates across 0°C to +70°C and draws only 0.5µW quiescent power, making it suitable for always-on signal-path applications.
Key Specifications

Pinout & Package
MAX4066ACPD+ is housed in a 14-pin plastic DIP (0.300″ width) with industry-standard footprint and lead spacing. Pin 1 is top-left corner when notch faces up; pin 14 is bottom-right.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 13 | NO1–NO4 | Normally open analog terminals - connect to signal sources or destinations; bidirectional conduction when enabled |
| 2, 5, 10, 12 | COM1–COM4 | Common analog terminals - serve as shared signal path nodes for each switch; bidirectional |
| 6, 7, 12, 14 | IN1–IN4 | Logic control inputs - TTL/CMOS-compatible; high = ON (closed), low = OFF (open) |
| 8 | GND | Analog/digital ground reference - must be connected to system common; decoupling recommended near pin |
| 14 | V+ | Positive supply - powers analog and logic sections; supports 2.0V–16V; no negative rail required |
Key Features

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+ | Higher 4Ω channel match (vs. 2Ω), 1nA off-leakage (vs. 100pA), same pinout and package | Suitable where ultra-low leakage is noncritical but cost sensitivity is higher | Select MAX4066CPD+ for cost-driven industrial controls where leakage <1nA suffices |
| ADG408BRUZ | 8-channel, single-pole single-throw; 44Ω RON at 15V; 100pA leakage; TSSOP-16 package | Offers greater channel density but requires PCB layout change and lacks DIP-14 option | Choose ADG408BRUZ when expanding to 8 channels and space-constrained PCBs justify re-layout |
Compared with MAX4066CPD+, the MAX4066ACPD+ delivers tighter channel matching and lower leakage for precision multiplexing; compared with ADG408BRUZ, it retains legacy DIP-14 compatibility and simpler 4-channel control but trades off channel count and modern package size.

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. The device is fully specified at 3V, 5V, and 12V supplies, and its analog signal range extends rail-to-rail (0V to V+), making MAX4066ACPD+ suitable for both low-power portable and industrial mid-rail applications.
Is MAX4066ACPD+ pin-compatible with the 74HC4066?
Yes, MAX4066ACPD+ is explicitly designed as a pin-compatible upgrade to the 74HC4066 in the 14-pin DIP package. All IN, COM, NO, V+, and GND pins align identically. However, MAX4066ACPD+ offers superior performance: lower on-resistance (45Ω vs. ~120Ω), tighter channel matching (2Ω vs. unspecified), and dramatically lower leakage (100pA vs. ~100nA), making MAX4066ACPD+ a direct functional and physical replacement.
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 0V to V+ analog signal range at V+ = 12V. This means the variation in RON across all signal voltages within that range does not exceed 6Ω - critical for maintaining consistent gain or attenuation in precision instrumentation and audio applications where signal-dependent distortion must be minimized. This specification is tested and guaranteed across temperature.
Does MAX4066ACPD+ support bidirectional analog signal flow?
Yes, MAX4066ACPD+ supports fully bidirectional analog signal flow between each COM and NO terminal pair. As a CMOS-based SPST switch, it imposes no polarity constraints: signals can pass from COM to NO or NO to COM with identical on-resistance, leakage, and bandwidth characteristics. This enables flexible routing in data-acquisition front-ends, audio patch bays, and communication interface multiplexers - a core design feature confirmed in the MAX4066ACPD+ truth table and pin descriptions.
What is the operating temperature range for MAX4066ACPD+?
The MAX4066ACPD+ is rated for commercial-grade operation from 0°C to +70°C ambient temperature. This is indicated by the "C" suffix in the part number and confirmed in the Ordering Information table. It is offered exclusively in the 14-pin plastic DIP package (PD) variant for this temperature grade. For extended ranges, alternatives like MAX4066AEPD (−40°C to +85°C) or MAX4066AMJD (−55°C to +125°C) are available, but MAX4066ACPD+ itself is qualified only for 0°C to +70°C.
