Product details
Overview
MAX4663EWE+ from Maxim Integrated is a quad SPST analog switch IC with two normally open (NO) and two normally closed (NC) channels, guaranteed break-before-make switching, 2.5Ω max on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail signal handling - used in precision data acquisition and reed-relay-replacement circuits.
For engineers reviewing the MAX4663EWE+ datasheet, MAX4663EWE+ pinout, MAX4663EWE+ application, or MAX4663EWE+ equivalent, this page delivers verified electrical specs, terminal roles, real-world use cases, and validated alternative parts for test equipment, avionics, and audio-signal routing designs.
Technical Context
The MAX4663EWE+ integrates four independent CMOS SPST switches in one 16-pin wide SO package, with dedicated IN/COM/NO/NC terminals per channel and separate VL logic supply for TTL/CMOS compatibility across full analog supply ranges. Its internal architecture ensures guaranteed break-before-make timing (5–125 ns) between complementary NO/NC pairs (Channels 1/4 and 2/3).
It supports rail-to-rail analog signals up to ±20V (dual) or 0–36V (single), maintains ≤0.5Ω on-resistance matching and flatness over full signal range, and achieves −56dB off-isolation and −60dB crosstalk at 1MHz - critical for low-distortion multiplexing in ADC front-ends and sample-and-hold systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - enables low insertion loss and minimal voltage drop in precision signal paths. |
| RON Match Between Channels | 0.5Ω max - ensures matched gain/attenuation across switched channels in differential or multi-path systems. |
| RON Flatness | 0.5Ω max over signal range - preserves linearity and THD performance for audio and instrumentation signals. |
| Break-Before-Make Time | 5–125 ns - prevents momentary short-circuit during channel switching in power-sensitive or fault-tolerant designs. |
| Off-Leakage Current | 0.5 nA max at +85°C - minimizes error in high-impedance sensor interfaces and integrator circuits. |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, automotive, and avionics supply rails without level-shifting. |
| Logic Compatibility | TTL/CMOS inputs with separate VL pin - allows independent logic voltage (e.g., 3.3V or 5V) regardless of analog supply levels. |
Pinout & Package
MAX4663EWE+ uses a 16-pin Wide SO (SOIC-W) package with 1.27mm pitch, 10.3mm × 7.5mm body, and exposed pad not electrically connected. Pin functions are validated per Maxim's official pin configuration diagram (Rev 0, 7/99).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; active-high logic drives NO/NC state per channel. |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - connect to signal source or load in SPST topology. |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - conduct when IN = low (MAX4663 uses NC2/NC3 and NO1/NO4). |
| 4 | V− | Negative analog supply - tied to GND for single-supply operation. |
| 5 | GND | Ground reference for logic and substrate - must be low-impedance return path. |
| 12 | VL | Separate logic supply - sets input threshold (0.8V/2.4V) independent of V+/V−. |
| 13 | V+ | Positive analog supply - defines upper rail for rail-to-rail signal handling. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Ensures no overlap conduction between NO and NC paths in dual-throw configurations - essential for safe signal routing in PBX and test fixtures. |
| Rail-to-rail analog signal handling | Supports full-scale input/output swing from V− to V+, eliminating clipping in ±15V op-amp or DAC buffer interfaces. |
| 2kV ESD protection (HBM) | Protects against handling damage and system-level transients without external clamps - reduces BOM count in field-deployed equipment. |
| Low charge injection (20pC typ) | Minimizes voltage glitch at COM node during switching - critical for sample-and-hold accuracy and low-drift integrators. |
| −56dB off-isolation @ 1MHz | Suppresses crosstalk between inactive channels in dense multiplexer layouts - improves SNR in multi-channel ADC systems. |
Applications
| Reed Relay Replacement | Test Equipment Signal Routing |
|---|---|
Use Scenario: Replacing electromechanical relays in automated test fixtures where cycle life, speed, and size matter. IC Role / Device Role / Timing Role: Quad SPST analog switch providing solid-state isolation and fast channel selection (tON = 400ns, tOFF = 300ns). Use Value: Eliminates relay wear-out, reduces actuation power by >99%, and shrinks PCB footprint by 70% vs. quad-DIP relay modules. |
Use Scenario: Multiplexing DUT signals to measurement instruments in ATE systems with strict leakage and distortion requirements. IC Role / Device Role / Timing Role: Precision analog switch enabling low-RON, low-leakage, and matched-channel routing for calibration-grade measurements. Use Value: Achieves <0.5nA off-leakage at +85°C and 0.5Ω RON match - directly improving measurement repeatability and reducing system drift. |
| Avionics Sensor Interface | Audio-Signal Routing |
Use Scenario: Conditioning and selecting analog sensor outputs (e.g., temperature, pressure) in flight-control subsystems with wide supply tolerance. IC Role / Device Role / Timing Role: Rail-to-rail analog switch operating from ±15V supplies while interfacing with 3.3V FPGA control logic via VL pin. Use Value: Maintains signal integrity across −40°C to +85°C without external level shifters or bias networks - simplifies DO-160 compliance testing. |
Use Scenario: Dynamic routing of line-level audio signals between sources and amplifiers in professional mixing consoles. IC Role / Device Role / Timing Role: Low-distortion SPST switch with 0.5Ω RON flatness preserving frequency response and minimizing THD+N. Use Value: Delivers <−100dB THD+N in 20Hz–20kHz band due to flat on-resistance and <20pC charge injection - avoids audible switching artifacts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ | Quad SPST, 1.8Ω RON, ±15V supply, no break-before-make guarantee, 40V max VDD–VSS. | Better RON and bandwidth but lacks guaranteed break-before-make - unsuitable for safety-critical NO/NC coexistence. | Select when lowest on-resistance and fastest switching (tON = 120ns) outweigh need for guaranteed channel separation. |
| TS5A3157DCKR | Single-pole double-throw (SPDT), 0.75Ω RON, 5V-only supply, no dual-rail support, no break-before-make. | Only supports single-channel SPDT; requires multiple units for quad function and cannot replace dual-supply operation. | Choose only for cost-sensitive, low-voltage (≤5.5V), space-constrained designs where rail-to-rail and dual-supply capability are unnecessary. |
Compared with ADG1412BRUZ and TS5A3157DCKR, the MAX4663EWE+ uniquely combines guaranteed break-before-make, dual-supply flexibility, and rail-to-rail operation - making it the only validated option for avionics and industrial test systems requiring fail-safe channel isolation and wide dynamic range.

FAQ
What is the guaranteed break-before-make time for MAX4663EWE+?
The MAX4663EWE+ guarantees a break-before-make interval of 5ns minimum to 125ns maximum between its complementary NO/NC pairs (e.g., IN1/NO1/NC1 and IN4/NO4/NC4). This specification is tested and documented in the Electrical Characteristics table under "tOPEN" for dual-supply conditions (V+ = +15V, V− = −15V), ensuring no overlap conduction during switching transitions in safety-critical routing applications.
Can MAX4663EWE+ operate from a single 5V supply?
Yes, the MAX4663EWE+ supports single-supply operation from +4.5V to +36V. At +5V, it maintains 4Ω typical on-resistance (within 2.5Ω max spec at higher voltages), rail-to-rail signal handling, and full TTL/CMOS logic compatibility via the VL pin. However, off-isolation degrades slightly at low V+ (−45dB typ at 1MHz), so verify system-level crosstalk requirements for 5V use cases.
What is the maximum continuous current rating per switch in MAX4663EWE+?
The MAX4663EWE+ supports ±200mA continuous current through each COM/NO/NC terminal, as specified in Absolute Maximum Ratings. This rating applies across the full operating temperature range (−40°C to +85°C) and is derated linearly above +70°C per the Wide SO package's 9.52mW/°C thermal coefficient - enabling reliable use in moderate-power analog routing without external current limiting.
Does MAX4663EWE+ require external ESD protection?
No, the MAX4663EWE+ includes >2kV human-body-model (HBM) ESD protection on all pins per Method 3015.7, as stated in its Features list. This integrated protection eliminates the need for external TVS diodes in most board-level ESD environments (IEC 61000-4-2 Level 2), though system-level surge events may still warrant additional clamping depending on end-equipment requirements.
How does the VL pin affect logic compatibility in MAX4663EWE+?
The VL pin on MAX4663EWE+ sets the logic threshold independently of analog supplies: VIN_H = 2.4V and VIN_L = 0.8V when VL = +5V, enabling direct interfacing with 3.3V or 5V microcontrollers even when V+ = +30V or V− = −15V. This decoupling prevents logic misstates during analog supply transients and removes the need for level translators in mixed-voltage systems.
