Product details
Overview
MAX4066AESD+T from Maxim Integrated is a quad, single-pole single-throw (SPST), CMOS analog switch optimized for low-voltage operation from +2.0V to +16V, featuring 45Ω on-resistance at 12V, 2Ω channel-to-channel matching, 100pA off-leakage at +25°C, and TTL/CMOS-compatible control inputs. It enables precise signal routing in battery-powered instrumentation and low-distortion audio paths.
For engineers reviewing the MAX4066AESD+T datasheet, MAX4066AESD+T pinout, MAX4066AESD+T application, or MAX4066AESD+T equivalent, key selection criteria include guaranteed on-resistance flatness (≤6Ω), -86dB crosstalk, 100MHz bandwidth, low charge injection (≤10pC), and SO-14 package compatibility with industrial temperature range (-40°C to +85°C).
Technical Context
The MAX4066AESD+T implements four independent bilateral SPST switches using CMOS transmission-gate architecture, supporting bidirectional analog signal flow between COM and NO terminals. Its logic interface accepts standard TTL/CMOS voltage levels, enabling direct connection to microcontrollers and FPGAs without level-shifting.
Designed for single-supply operation, it handles analog signals from GND to V+ across its full specified range, with internal ESD protection exceeding 2000V (Method 3015.7). The device maintains tight on-resistance matching (2Ω max) and low distortion (0.03%) critical for precision multiplexing and sample-and-hold circuits.
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 signal paths |
| Channel Matching (∆RON) | 2Ω max - guarantees consistent gain and timing across all four channels in multiplexer applications |
| Off-Leakage Current | 100pA max at +25°C - preserves accuracy in high-impedance sensor interfaces and sample-and-hold hold capacitors |
| Bandwidth | >100MHz - supports fast-switching video, communication, and wideband data-acquisition signals |
| Crosstalk | -86dB - prevents interference between adjacent switched channels in dense routing layouts |
| Charge Injection | 10pC max - minimizes voltage glitch on hold capacitors during switching transitions |
| Supply Range | +2.0V to +16V - enables use in both low-power portable systems and industrial 12V rail environments |
Pinout & Package
The MAX4066AESD+T is housed in a 14-pin narrow SO (Small Outline) package, 150-mil body width, with standard JEDEC MO-153 footprint and gull-wing leads. Pin 1 is marked by a beveled corner or dot; pin count follows standard SO-14 numbering (1–14, top view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 13 | NO1–NO4 | Normally open analog terminals - connect to signal sources when switch is enabled; bidirectional |
| 2, 4, 9, 10 | COM1–COM4 | Common analog terminals - serve as input/output junctions for each switch; bidirectional |
| 5, 6, 7, 12 | IN1–IN4 | Logic control inputs - TTL/CMOS-compatible; high = ON, low = OFF per channel |
| 14 | V+ | Positive supply rail - powers analog and logic sections; must be applied before control inputs |
| 7 | GND | Ground reference - common return for supply and analog signals; decoupling required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Bilateral signal handling | Supports analog signal flow in either direction between COM and NO, simplifying PCB layout in bidirectional sensor or audio paths |
| Guaranteed 2Ω channel matching | Ensures uniform on-resistance across all four switches - critical for ratio-metric measurements and multi-channel calibration |
| 100pA off-leakage at +25°C | Enables stable DC coupling in high-impedance medical sensors and precision data loggers without drift-induced errors |
| Low 0.03% THD | Maintains signal fidelity in audio routing and instrumentation amplifiers where harmonic distortion degrades measurement integrity |
| ESD protection >2000V | Meets IEC 61000-4-2 Level 2 requirements - reduces need for external protection in handheld and field-deployable equipment |

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 |
|---|---|---|---|
| ADG1414BRUZ | Higher on-resistance (1.8Ω typical at 5V), wider supply range (±15V dual or 5V single), 16-TSSOP package | Better suited for high-voltage industrial muxing; not pin-compatible with SO-14 | Select when bipolar supplies or sub-1Ω RON at low voltage are required; requires PCB redesign |
| TS5A4624DCKR | Lower voltage range (1.65–5.5V), smaller 6-pin SC70 package, 0.7Ω RON at 3.3V, but only dual-channel | Optimized for space-constrained, low-voltage portable designs; lacks quad integration | Choose for ultra-compact 3.3V systems needing two switches; additional ICs needed for quad functionality |
Compared with ADG1414BRUZ and TS5A4624DCKR, the MAX4066AESD+T uniquely balances industrial temperature support (-40°C to +85°C), SO-14 pinout compatibility, 45Ω RON at 12V, and 100pA leakage-making it optimal for battery-operated test equipment and ruggedized sensor concentrators where layout stability and leakage-critical hold times matter.

FAQ
What is the maximum supply voltage rating for the MAX4066AESD+T?
The MAX4066AESD+T has an absolute maximum supply voltage (V+) of +17V, with recommended operating range from +2.0V to +16V. Operation beyond +17V risks permanent damage. The device is fully specified at 3V, 5V, and 12V supply levels, and its analog signal range extends from GND to V+, making it suitable for single-rail systems without negative supplies.
Does the MAX4066AESD+T support bidirectional analog signal flow?
Yes, the MAX4066AESD+T supports fully bidirectional analog signal flow between each COM and NO terminal pair. As a CMOS transmission-gate-based SPST switch, it imposes no polarity constraints on the analog signal - voltage or current can pass equally well from COM to NO or NO to COM, provided the signal remains within the 0V to V+ range and stays within absolute maximum ratings.
What is the guaranteed on-resistance matching between channels for the MAX4066AESD+T?
The MAX4066AESD+T guarantees a maximum on-resistance match (∆RON) of 2Ω between any two channels at V+ = 12V and TA = +25°C. This specification ensures highly consistent conduction characteristics across all four switches, which is critical for applications like ratiometric sensor measurement, multi-channel calibration, and balanced signal routing where mismatch introduces gain or offset errors.
Is the MAX4066AESD+T pin-compatible with the industry-standard 74HC4066?
Yes, the MAX4066AESD+T is explicitly pin-compatible with the 74HC4066 in SO-14 and DIP-14 packages. Its pinout matches the legacy 74HC4066 function-for-function, allowing direct replacement in existing designs - though the MAX4066AESD+T delivers superior performance including lower on-resistance (45Ω vs. ~120Ω), tighter matching, and significantly lower leakage (100pA vs. ~10nA), especially at elevated temperatures.
What is the operating temperature range specified for the MAX4066AESD+T?
The MAX4066AESD+T is rated for operation from -40°C to +85°C, denoted by the "E" grade suffix in its ordering code. This extended industrial temperature range makes it suitable for deployment in automotive cabin modules, outdoor IoT sensors, and factory automation equipment where ambient conditions exceed commercial-grade limits, while maintaining full electrical specifications across the entire range.
