Product details
Overview
MAX4066AESD+ 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, and 100pA COM 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 MAX4066AESD+ datasheet, MAX4066AESD+ pinout, MAX4066AESD+ application, or MAX4066AESD+ equivalent, key selection criteria include guaranteed on-resistance flatness (≤6Ω), low THD (0.03%), high off-isolation (−58dB), and TTL/CMOS-compatible control logic across industrial temperature range (−40°C to +85°C).
Technical Context
The MAX4066AESD+ implements a fully complementary CMOS transmission-gate architecture with matched P- and N-channel devices per channel, enabling rail-to-rail analog signal handling (0V to V+) and bidirectional conduction. Its design ensures consistent on-resistance over the full signal range and minimal charge injection (≤10pC) for sample-and-hold stability.
Control inputs accept standard TTL/CMOS logic levels independent of supply voltage, and internal ESD protection exceeds 2000V per Method 3015.7. The device operates with zero static power draw in both on/off states-supply current is ≤1µA across temperature-and supports dynamic bandwidth >100MHz with −86dB crosstalk suppression.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 45Ω max at V+ = 12V - ensures minimal signal attenuation and voltage drop in precision analog paths |
| Channel Matching (∆RON) | 2Ω max - enables accurate gain-matching in multi-channel instrumentation and multiplexed sensor interfaces |
| COM Off-Leakage Current | 100pA max at +25°C - critical for maintaining accuracy in high-impedance sample-and-hold and battery-monitoring circuits |
| Off Isolation | −58dB at 1MHz - suppresses unwanted coupling between inactive and active signal paths |
| THD | 0.03% at 12V - preserves fidelity in low-distortion audio routing applications |
| Supply Range | +2.0V to +16V single supply - supports direct integration into 3.3V, 5V, and 12V systems without level-shifting |
| Bandwidth | >100MHz - accommodates fast-switching digital signals and wideband analog waveforms |
Pinout & Package
MAX4066AESD+ is housed in a 14-pin narrow SO (Small Outline) package, 150-mil body width, with gull-wing leads and JEDEC MS-012AC compliance. Pin pitch is 1.27mm; package dimensions are 8.65mm × 3.90mm × 1.75mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2, 5, 10, 12 | COM1–COM4 (Common) | Bidirectional analog input/output nodes; routed to corresponding NO terminal when enabled |
| 6, 7, 12, 14 | IN1–IN4 (Logic Inputs) | TTL/CMOS-compatible digital controls; high = ON, low = OFF for respective channel |
| 8 | GND | Analog and digital ground reference; must be low-impedance for leakage and noise performance |
| 14 | V+ | Positive supply rail; powers analog switch core and logic interface; supports 2.0V–16V operation |
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 |
|---|---|---|---|
| MAX4066ACSD+ | Same pinout and electrical specs, but rated for 0°C to +70°C only - lacks extended temperature qualification | Suitable for commercial-grade consumer electronics, not industrial or automotive deployments | Select MAX4066ACSD+ only if ambient operating temperature remains within 0°C–70°C and long-term reliability at −40°C is not required |
| ADG408BRUZ | 8-channel (not quad), 44Ω RON at 15V, −40°C to +85°C, but higher 1nA leakage and no 3V guarantee | Offers more channels but trades off leakage and low-voltage performance; requires 15V min for full spec compliance | Choose ADG408BRUZ only when channel count >4 is mandatory and leakage <100pA is not critical |
Compared with MAX4066ACSD+, MAX4066AESD+ delivers guaranteed −40°C operation and identical performance at lower cost than ADG408BRUZ, making it optimal for industrial data acquisition where leakage, temperature range, and 3V compatibility are decisive.

FAQ
What is the maximum supply voltage rating for MAX4066AESD+?
The absolute maximum supply voltage (V+) for MAX4066AESD+ is +17V, with recommended continuous operation up to +16V. Operation beyond this risks permanent damage. The device is fully specified from +2.0V to +16V, including guaranteed 45Ω on-resistance at 12V and 170Ω at 3V. Always observe proper power-supply sequencing-apply V+ before logic inputs-to avoid latch-up or overstress.
Does MAX4066AESD+ support rail-to-rail analog signal switching?
Yes, MAX4066AESD+ supports rail-to-rail analog signal switching: its specified analog signal range is 0V to V+, meaning signals from ground up to the positive supply rail can pass through the switch without clipping or distortion. This capability is enabled by its fully complementary CMOS architecture and is validated across all supply voltages (3V, 5V, 12V) and temperatures (−40°C to +85°C).
Is MAX4066AESD+ pin-compatible with the industry-standard 74HC4066?
Yes, MAX4066AESD+ is explicitly designed as a pin-compatible upgrade to the 74HC4066. It shares identical pin assignments for IN1–IN4, COM1–COM4, NO1–NO4, V+, and GND in the 14-pin SO package. Unlike the 74HC4066, MAX4066AESD+ guarantees performance down to +2.0V supply and offers superior leakage (100pA vs. ~10nA), on-resistance matching (2Ω vs. ~10Ω), and ESD protection (>2000V vs. ~200V).
What is the typical THD performance of MAX4066AESD+ and under what conditions is it measured?
MAX4066AESD+ delivers 0.03% total harmonic distortion (THD) at +25°C with a 12V supply, 5Vp-p sine-wave input, and 600Ω source/load impedance. This value is measured across the full audio band (20Hz–20kHz) and reflects the device's low nonlinearity due to matched transistor geometry and low on-resistance flatness (≤6Ω). THD remains below 0.05% over the full −40°C to +85°C range.
Can MAX4066AESD+ be used in sample-and-hold circuits, and what parameter ensures stability?
Yes, MAX4066AESD+ is well-suited for sample-and-hold circuits due to its low charge injection (≤10pC), which minimizes voltage step errors at the hold capacitor when the switch opens. This parameter-verified at V+ = 12V, VGEN = 0V, RGEN = 0Ω, and CL = 1.0nF-is critical for maintaining acquisition accuracy. Combined with 100pA off-leakage, it enables long hold times (>100ms) with sub-LSB error in 16-bit systems.
