Product details
Overview
MAX4066CSD+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 (MAX4066A variant), and 0.5µW quiescent power consumption. It serves as a bilateral signal routing device in battery-powered instrumentation and audio path switching.
For engineers reviewing the MAX4066CSD+T datasheet, MAX4066CSD+T pinout, MAX4066CSD+T application, or MAX4066CSD+T equivalent, key selection criteria include guaranteed on-resistance flatness (≤6Ω), low off-leakage current (100pA max for MAX4066A), TTL/CMOS-compatible control inputs, and SO-14 package compatibility with legacy 74HC4066 layouts.
Technical Context
The MAX4066CSD+T 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 architecture guarantees monotonic on-resistance over the full analog signal range and supports single-supply operation without negative biasing.
Control logic accepts standard TTL/CMOS voltage thresholds (VINH ≥ 2.4V at V+ = 5V; VINL ≤ 0.8V), and internal ESD protection exceeds 2000V per Method 3015.7. The device maintains low distortion (0.03% THD) and high bandwidth (>100MHz) due to matched channel design and minimized parasitic capacitance (9pF NO/OFF, 9pF COM/OFF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (12V) | 45Ω max - ensures minimal signal attenuation and voltage drop in precision signal paths |
| Channel Matching (ΔRON) | 2Ω max (MAX4066A) - critical for multiplexer accuracy and differential signal integrity |
| Off-Leakage Current | 100pA max at +25°C - preserves charge in sample-and-hold and high-impedance sensor interfaces |
| Supply Range | +2.0V to +16V - supports direct integration into 3V, 5V, and 12V systems without level-shifting |
| Bandwidth | >100MHz - enables video and fast data-acquisition signal routing without roll-off |
| THD | 0.03% - meets fidelity requirements for low-distortion audio switching applications |
| Turn-On/Off Time | 25ns / 15ns typical - suitable for high-speed multiplexing in automated test equipment |
Pinout & Package
MAX4066CSD+T is housed in a 14-pin narrow SO (Small Outline) package, 150-mil body width, with standard JEDEC MO-153 footprint. Pin 1 is marked by a beveled corner or dot; pin count and spacing comply with industry-standard SOIC-14 layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 13 | NO1–NO4 | Normally open analog terminals - connect to signal sources when switch is enabled |
| 2, 5, 10, 12 | COM1–COM4 | Common analog terminals - bidirectional I/O nodes shared with NO pins |
| 3, 11 | N.C. | No internal connection - must remain unconnected; no pull-up/down required |
| 6, 7, 12, 14 | IN1–IN4 | TTL/CMOS logic inputs - active-high control signals for corresponding switches |
| 8 | GND | Analog/digital ground reference - common return for all channels and logic |
| 14 | V+ | Positive supply rail - powers analog switch core and input buffers; supports 2.0V–16V range |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility with 74HC4066 | Direct PCB replacement in legacy designs without layout modification |
| Guaranteed on-resistance flatness | ≤6Ω over full signal range - ensures consistent gain and linearity across input amplitude |
| Low crosstalk | −86dB - prevents signal coupling between adjacent switched channels in dense routing |
| High off-isolation | −58dB - blocks unwanted signal bleed in multiplexer 'off' states |
| ESD robustness | >2000V HBM - reduces field failure risk during handling and system integration |
Applications
| Battery-Powered Data Loggers | Audio Signal Routing |
|---|---|
Use Scenario: Multiplexing multiple sensor outputs (thermocouples, RTDs) into a single ADC channel under ultra-low-power constraints. IC Role / Device Role / Timing Role: Quad SPST analog switch providing low-leakage, rail-to-rail signal path selection controlled by microcontroller GPIOs. Use Value: 100pA off-leakage preserves microvolt-level sensor integrity; 0.5µW quiescent power extends battery life in always-on monitoring. |

IC Role / Device Role / Timing Role: High-bandwidth analog switch managing signal path reconfiguration during mode transitions. Use Value: >100MHz bandwidth supports baseband and IF switching; low charge injection (<10pC) prevents DC offset shifts in sensitive receiver chains. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRUZ | 8-channel, single-pole single-throw; higher on-resistance (100Ω typ at 5V); requires dual supply (±15V or single 5V with V– tied to GND) | Used where channel count >4 is needed; less suitable for battery operation due to higher leakage (1nA) | Select when expanding beyond 4 channels or requiring industry-standard ADI footprint; verify supply configuration compatibility. |
| TS5A23157DGSR | Quad SPST; lower on-resistance (0.9Ω typ at 3.3V); narrower supply range (1.65V–5.5V); smaller US8 package | Better for ultra-low-voltage (1.8V) digital systems; not rated for 12V operation or industrial temperature range | Prefer for space-constrained, 3.3V-only designs; avoid in 12V or extended-temperature environments. |
Compared with MAX4066CSD+T, ADG408BRUZ offers more channels but sacrifices low-voltage operation and leakage performance, while TS5A23157DGSR delivers lower on-resistance at 3.3V but lacks 12V capability and industrial temperature support - making MAX4066CSD+T optimal for wide-supply, low-leakage, quad-channel analog routing.

FAQ
What is the maximum supply voltage rating for MAX4066CSD+T?
The MAX4066CSD+T has an absolute maximum V+ rating of +17V, with guaranteed functional operation from +2.0V to +16V. Operation above +16V risks permanent damage, and the device is fully specified at 3V, 5V, and 12V supply conditions per its electrical characteristics table. Always observe proper power sequencing (V+ before logic inputs) to prevent latch-up or overstress.
Does MAX4066CSD+T support rail-to-rail analog signal switching?
Yes, MAX4066CSD+T supports rail-to-rail analog signal handling from GND to V+, as confirmed by its specified analog signal range (0V to V+) and internal clamp diode structure. This allows full-swing AC or DC signals - such as ±5V audio or 0–12V sensor outputs - to pass through the switch without clipping, provided V+ remains within the +2.0V to +16V operating range.
Is MAX4066CSD+T pin-compatible with the 74HC4066?
Yes, MAX4066CSD+T is explicitly designed as a pin-compatible upgrade to the 74HC4066, sharing identical SO-14 pinout and logic-level compatibility. It improves upon the HC4066 with lower on-resistance (45Ω vs. ~120Ω), tighter channel matching, and guaranteed operation down to +2.0V - enabling drop-in replacement in existing 74HC4066 layouts without PCB changes.
What is the off-leakage current specification for MAX4066CSD+T at room temperature?
The MAX4066CSD+T is the standard-grade version of the MAX4066A family; its datasheet specifies 1nA max COM off-leakage and NO off-leakage at +25°C (not the 100pA of the MAX4066A variant). This value is 100% tested at maximum-rated hot temperature and correlated to +25°C, making it suitable for most general-purpose analog switching where sub-nA leakage is not required.
Can MAX4066CSD+T operate from a single 3.3V supply?
Yes, MAX4066CSD+T is fully functional at +3.3V: its guaranteed on-resistance is 170Ω max at 3V supply, and logic inputs accept standard 3.3V CMOS thresholds (VINH ≥ 2.4V, VINL ≤ 0.8V). Performance metrics including bandwidth (>100MHz), THD (0.03%), and leakage (1nA) remain valid, confirming suitability for modern low-voltage embedded systems.
