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 off-leakage at +25°C. It operates as a bilateral signal routing device in battery-powered instrumentation and low-distortion audio paths.
For engineers reviewing the MAX4066AESD datasheet, MAX4066AESD pinout, MAX4066AESD application, or MAX4066AESD equivalent, key selection criteria include guaranteed on-resistance flatness (6Ω), TTL/CMOS-compatible control inputs, -86dB crosstalk, 100MHz bandwidth, and SO-14 package compatibility with industrial temperature range (-40°C to +85°C).
Technical Context
The MAX4066AESD implements four independent SPST switches using complementary CMOS transistor pairs per channel, enabling bidirectional analog signal conduction with rail-to-rail voltage handling (GND to V+). Its logic interface accepts standard TTL/CMOS voltage thresholds, eliminating level-shifting requirements in mixed-supply systems.
Designed for precision signal routing, it guarantees 4Ω on-resistance flatness over its full analog signal range and maintains ≤100pA COM-off leakage across its -40°C to +85°C operating range. The device achieves <0.03% total harmonic distortion at 1kHz with 5Vp-p signals, supporting high-fidelity audio switching without external buffering.

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 |
|---|---|---|---|
| ADG406BRUZ | 16-pin TSSOP, ±15V dual-supply capable, 75Ω RON at +15V, 1nA leakage | Requires dual supply; higher RON limits low-voltage precision use | Select for bipolar signal handling where MAX4066AESD's unipolar 2–16V range is insufficient |
| TS5A4624DCKR | 6-pin SC70, 0.7Ω RON at 3.3V, 100nA leakage, -40°C to +85°C | Single-channel only; lower voltage rating (up to 3.6V); no QSOP/SO-14 footprint | Choose for ultra-low RON in space-constrained 3.3V systems where quad integration is not required |
Compared with ADG406BRUZ and TS5A4624DCKR, the MAX4066AESD uniquely balances wide supply range (2–16V), low leakage (100pA), and SO-14 compatibility-making it optimal for industrial and portable designs needing quad SPST switching without dual supplies or footprint redesign.

FAQ
What is the maximum supply voltage rating for MAX4066AESD?
The MAX4066AESD has an absolute maximum supply voltage (V+) of +17V, with guaranteed functional operation from +2.0V to +16V. Operation beyond +16V risks permanent damage, and the device must never be subjected to voltages exceeding the Absolute Maximum Ratings specified in the datasheet. The MAX4066AESD is rated for continuous operation at 12V, 5V, and 3V supplies with fully characterized performance across all three conditions.
Does MAX4066AESD support bidirectional analog signal flow?
Yes, the MAX4066AESD supports fully bidirectional analog signal conduction on all four SPST channels. Each COM–NO pair functions identically in either direction, with identical on-resistance, leakage, and bandwidth specifications regardless of signal polarity or current direction. This capability is inherent to its CMOS transmission-gate architecture and is explicitly confirmed in the device's truth table and electrical characteristics tables.
What is the operating temperature range of MAX4066AESD?
The MAX4066AESD is specified for operation from -40°C to +85°C, denoted by the "E" grade suffix in its ordering code. This extended industrial temperature range is validated across all key parameters-including on-resistance, leakage current, switching speed, and THD-and is supported by both the SO-14 package construction and internal process design. The "AESD" suffix explicitly identifies this temperature grade and package type.
Is MAX4066AESD pin-compatible with the 74HC4066?
Yes, the MAX4066AESD is pin-compatible with the industry-standard 74HC4066 in the 14-pin SO package. Pin assignments for V+, GND, IN1–IN4, COM1–COM4, and NO1–NO4 match exactly, enabling direct replacement without PCB modification. However, the MAX4066AESD delivers superior performance-including lower on-resistance (45Ω vs. ~120Ω), tighter channel matching (2Ω vs. unspecified), and lower leakage (100pA vs. ~10nA)-while maintaining identical logic-level compatibility.
What is the typical turn-on time for MAX4066AESD at 5V supply?
The typical turn-on time (tON) for MAX4066AESD at a +5V supply is 43ns, with a maximum guaranteed value of 125ns across the full -40°C to +85°C temperature range. This parameter is measured under standardized conditions (VNO = 3V, RL = 50Ω, CL = 5pF) and reflects the propagation delay from logic input transition to 90% of final analog output voltage. Fast switching enables high-throughput multiplexing in data acquisition and automated test systems.
