Product details
Overview
MAX4066AEEE+ from Maxim Integrated is a quad, single-pole single-throw (SPST), CMOS analog switch optimized for low-voltage, low-leakage signal routing. It operates from +2.0V to +16V, delivers 45Ω on-resistance at 12V, 2Ω channel-to-channel matching, and 100pA COM off-leakage at +25°C - making it suitable for precision sample-and-hold circuits and battery-powered audio routing.
For engineers reviewing the MAX4066AEEE+ datasheet, MAX4066AEEE+ pinout, MAX4066AEEE+ application, or MAX4066AEEE+ equivalent, key selection criteria include guaranteed 2Ω matching across channels, sub-100pA leakage at +25°C, 100MHz bandwidth, TTL/CMOS-compatible control, and QSOP-16 packaging for high-density PCB layouts.
Technical Context
The MAX4066AEEE+ implements four independent bilateral SPST switches using CMOS transmission-gate architecture with rail-to-rail analog signal handling (0V to V+). Each switch features matched P- and N-channel MOSFETs to minimize on-resistance flatness and distortion.
Control inputs accept TTL/CMOS logic levels (VINL ≤ 0.8V, VINH ≥ 2.4V at V+ = 5V) and drive internal gate drivers that ensure fast, low-charge-injection switching (2–10pC typical). The device supports single-supply operation only - no negative rail required - and handles signals up to V+ without clamping when used within absolute maximum ratings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 45Ω max at V+ = 12V - ensures minimal signal attenuation in precision DC-coupled paths |
| Channel Matching (∆RON) | 2Ω max - critical for multi-channel instrumentation where gain/offset tracking matters |
| COM Off-Leakage Current | 100pA max at +25°C - enables accurate long-duration sample-and-hold hold times (>1s with 1µF) |
| Bandwidth | >100MHz - supports video, high-speed data acquisition, and broadband RF signal routing |
| Supply Range | +2.0V to +16V - allows direct integration into 3.3V, 5V, and 12V systems without level-shifting |
| Charge Injection | 2–10pC - limits voltage glitch on sampled nodes, reducing need for hold capacitor oversizing |
| Off Isolation | -58dB at 1MHz - suppresses crosstalk between inactive and active signal paths |
Pinout & Package
MAX4066AEEE+ is housed in a 16-pin QSOP package (3.99mm × 4.98mm, 0.635mm pitch), rated for -40°C to +85°C operation. The package features gull-wing leads, moisture sensitivity level 1, and RoHS-compliant finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NO1–NO4 | Normally open analog terminals - bidirectional signal path when corresponding switch is ON |
| 2, 4, 9, 10 | COM1–COM4 | Common analog terminals - connect to signal source/load; bidirectional with NO pins |
| 5, 6, 7, 12 | IN1–IN4 | TTL/CMOS logic inputs - high = ON state, low = OFF state for respective switch |
| 13, 14, 15, 16 | N.C. | No internal connection - must be left floating or tied to GND per layout best practice |
| 16 | V+ | Positive supply rail - powers analog and logic sections; must be decoupled locally |
| 8 | GND | Analog/digital ground reference - shared return for all channels and logic |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed 2Ω channel matching | Enables precise multi-channel gain/phase alignment in differential or parallel-signal paths |
| 100pA COM off-leakage at +25°C | Extends effective hold time in sample-and-hold stages beyond 1 second with standard 1µF capacitors |
| 100MHz on-channel bandwidth | Supports composite video, USB 1.1 signaling, and wideband sensor interface applications |
| Rail-to-rail analog signal range (0V to V+) | Eliminates external biasing for unipolar sensor outputs and DAC-driven signals |
| TTL/CMOS-compatible logic inputs | Direct interfacing with microcontrollers, FPGAs, and logic families without level shifters |

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 |
|---|---|---|---|
| ADG1611BRUZ | Lower on-resistance (0.5Ω typ), but higher leakage (2nA), requires dual supply (±5V or +5V/–5V) | Preferred for ultra-low-RON precision instrumentation; unsuitable for single-supply battery systems | Select ADG1611BRUZ only if dual supply is available and sub-1Ω RON is mandatory |
| TS5A3157DCKR | Smaller 6-pin SC70 package, lower voltage range (1.65V–5.5V), higher RON (8Ω typ at 3.3V), no guaranteed matching spec | Better for space-constrained 3.3V IoT nodes; lacks channel-matching guarantee needed for multi-channel sync | Choose TS5A3157DCKR for compact 3.3V designs where matching isn't critical |
Compared with ADG1611BRUZ and TS5A3157DCKR, the MAX4066AEEE+ uniquely balances single-supply flexibility (+2V to +16V), guaranteed 2Ω matching, and 100pA leakage - making it the optimal choice for industrial and medical systems requiring channel consistency and low-power reliability without dual-rail complexity.

FAQ
What is the operating temperature range for MAX4066AEEE+?
The MAX4066AEEE+ is specified for operation from -40°C to +85°C. This extended industrial temperature range ensures reliable performance in outdoor instrumentation, automotive cabin modules, and factory-floor PLC I/O cards where ambient conditions exceed commercial-grade limits. All electrical parameters - including 2Ω channel matching and 100pA leakage - are guaranteed across this full range.
Does MAX4066AEEE+ support rail-to-rail analog signal switching?
Yes, MAX4066AEEE+ supports rail-to-rail analog signal switching from 0V to V+. When V+ = 5V, signals from 0V to 5V pass through with minimal distortion (0.03% THD) and flat on-resistance (≤45Ω). This eliminates the need for external level-shifting circuitry when interfacing with unipolar sensors, DACs, or ADCs referenced to the same supply.
Is MAX4066AEEE+ pin-compatible with the standard 74HC4066?
No, MAX4066AEEE+ is not pin-compatible with the 74HC4066. While both are quad SPST analog switches, the MAX4066AEEE+ uses a 16-pin QSOP package with dedicated NO/COM/IN pins and four N.C. pins, whereas the 74HC4066 uses a 14-pin DIP/SO with different pin assignments (e.g., shared IN/COM pins). Board redesign is required for substitution.
What is the maximum analog signal voltage the MAX4066AEEE+ can handle?
The MAX4066AEEE+ can handle analog signals from 0V to V+, with V+ rated from +2.0V to +16V. Absolute maximum analog voltage at any NO or COM pin is (V+ + 0.3V), per internal diode clamping. For example, with V+ = 12V, signals up to 12.3V are safe - but sustained operation above V+ risks latch-up or damage. Always observe the -0.3V to (V+ + 0.3V) absolute rating window.
How does the 2Ω channel matching specification benefit system design?
The 2Ω channel matching (∆RON) in MAX4066AEEE+ ensures consistent gain and phase response across all four switches - critical in applications like multi-channel data acquisition, differential signal routing, or synchronized sensor multiplexing. This tight matching reduces calibration overhead, improves common-mode rejection in instrumentation amplifiers, and maintains timing integrity in parallel-sampled systems without per-channel trimming.
