Product details
Overview
MAX4663CWE from Maxim Integrated is a quad SPST analog switch IC with two normally open (NO) and two normally closed (NC) channels, featuring 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 - ideal for precision ADC multiplexing and reed-relay replacement in test equipment.
For engineers reviewing the MAX4663CWE datasheet, MAX4663CWE pinout, MAX4663CWE application, or MAX4663CWE equivalent, this page delivers verified electrical specs, terminal roles, real-world use cases, and validated alternative parts for signal routing, data acquisition, and avionics switching design.
Technical Context
The MAX4663CWE implements CMOS-based SPST analog switches with independent logic-controlled NO/NC pairs, where Channels 1 & 4 are NO and Channels 2 & 3 are NC. Its break-before-make timing is guaranteed at 5ns min / 125ns max, preventing momentary short-circuits during state transitions.
It supports dual ±4.5V to ±20V or single +4.5V to +36V analog supplies, with a separate VL pin enabling TTL/CMOS-compatible control inputs across the full supply range. On-resistance flatness is 0.7Ω max over ±10V signal range, and off-isolation exceeds –56dB at 1MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 4Ω max at +25°C, ensuring minimal voltage drop and signal attenuation in precision analog paths |
| RON Match Between Channels | 0.4Ω max, enabling matched gain/attenuation in differential or multi-channel sampling systems |
| RON Flatness | 0.7Ω max over ±10V, preserving linearity for rail-to-rail audio and sensor signals |
| Off-Leakage Current | 0.5nA max at +85°C, critical for high-impedance sample-and-hold and low-current sensor interfaces |
| Break-Before-Make Time | 5–125ns, eliminating transient shorts in power-switching or signal-path reconfiguration |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual, supporting industrial and avionics voltage rails |
| Logic Compatibility | TTL/CMOS via dedicated VL pin, decoupling control logic from analog supply variations |
Pinout & Package
MAX4663CWE is housed in a 16-pin Wide SO (SOIC-W) package, 7.5mm body width, 1.27mm pitch, RoHS-compliant, with exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs: IN1/IN4 drive NO switches; IN2/IN3 drive NC switches |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal path connection points |
| 3, 6 | NC2, NC3 | Normally closed analog terminals - conduct when corresponding IN = 0 |
| 11, 14 | NO1, NO4 | Normally open analog terminals - conduct when corresponding IN = 1 |
| 4 | V− | Negative analog supply rail; tied to GND for single-supply operation |
| 5 | GND | Ground reference for logic and substrate; must be low-impedance for leakage control |
| 12 | VL | Independent logic supply input - sets input threshold regardless of V+/V− |
| 13 | V+ | Positive analog supply rail - defines upper signal swing limit and RON performance |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Prevents signal shorting during channel switching - essential for fault-tolerant multiplexers |
| Rail-to-rail analog signal handling | Supports full V− to V+ range without clipping - enables direct interfacing with op-amps and ADC drivers |
| 2kV ESD protection (HBM) | Robust handling of board-level ESD events without external protection components |
| Low charge injection (20pC typ) | Minimizes voltage glitch in sample-and-hold and switched-capacitor circuits |
| Matched on-resistance (0.4Ω max) | Ensures consistent channel gain in multi-path instrumentation and calibration systems |
Applications
| ADC Multiplexing | Avionics Signal Routing |
|---|---|
Use Scenario: Selecting among multiple sensor inputs (e.g., temperature, pressure, position) feeding a single high-resolution ADC in flight control units. IC Role / Device Role / Timing Role: Quad SPST switch providing isolated, low-distortion analog paths with guaranteed break-before-make to prevent cross-talk between sensors. Use Value: Eliminates mechanical relay wear-out while maintaining <0.01% gain error due to 0.4Ω RON match and <2.5Ω RON. |
Use Scenario: Reconfiguring RF front-end signal paths (e.g., antenna selection, filter bypass) in airborne communication transceivers. IC Role / Device Role / Timing Role: Analog switch managing DC-coupled control lines and low-frequency bias paths with rail-to-rail capability up to +36V. Use Value: Enables compact, solid-state replacement of hermetically sealed relays - reducing weight, shock sensitivity, and power consumption. |
| Test Equipment Channel Switching | Audio Signal Matrix |
Use Scenario: Automated test system switching between DUTs and measurement instruments (DMM, SMU) under software control. IC Role / Device Role / Timing Role: Precision analog switch delivering low leakage (<0.5nA @ +85°C) and high off-isolation (>–56dB) for accurate parametric testing. Use Value: Maintains measurement integrity across temperature and voltage ranges without recalibration drift from RON variation. |
Use Scenario: Professional audio console routing analog line-level signals (±10V) between mic preamps, effects processors, and outputs. IC Role / Device Role / Timing Role: Low-distortion, low-crosstalk (–60dB) analog switch handling full audio bandwidth with flat RON over signal range. Use Value: Preserves dynamic range and channel separation - no audible switching artifacts due to 20pC charge injection and 5ns break time. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG465BRUZ | Single-supply only (+3V to +36V); no dual-supply support; 4.5Ω RON typical; no guaranteed break-before-make | Suitable for cost-sensitive industrial PLC I/O modules but not for dual-rail avionics or safety-critical break-before-make paths | Select when only single-supply operation is needed and timing-critical switching is absent |
| TS5A3157DCKR | Lower voltage range (1.65V to 5.5V); 0.75Ω RON typical; no ESD rating >1.5kV; no break-before-make guarantee | Targeted at portable battery-powered audio routing, not high-voltage industrial or aerospace signal conditioning | Choose only for low-voltage, low-power consumer applications - incompatible with ±15V test equipment or +36V industrial rails |
Compared with MAX4663CWE, ADG465BRUZ lacks dual-supply flexibility and guaranteed break-before-make, while TS5A3157DCKR operates outside industrial voltage ranges and offers no ESD robustness - making MAX4663CWE uniquely suited for high-reliability, wide-supply, fault-avoidant analog routing.

FAQ
What is the maximum supply voltage rating for MAX4663CWE?
The MAX4663CWE supports +4.5V to +36V single-supply operation or ±4.5V to ±20V dual-supply operation. Absolute maximum ratings specify V+ to GND ≤ +44V and V− to GND ≥ −44V, but continuous operation beyond ±20V or +36V violates datasheet specifications and risks permanent damage. Always observe the recommended operating ranges defined in the Electrical Characteristics tables.
Does MAX4663CWE support true break-before-make switching across all temperature and voltage conditions?
Yes - the MAX4663CWE guarantees break-before-make behavior with tOPEN of 5ns minimum to 125ns maximum over the full operating temperature range (0°C to +70°C for the 'C' grade) and supply conditions. This specification is tested and ensured per the datasheet's Switch Dynamic Characteristics table and applies to all four channels simultaneously.
Can MAX4663CWE operate with V− grounded and only a positive supply?
Yes - MAX4663CWE fully supports single-supply operation with V− connected to GND and V+ set between +4.5V and +36V. In this configuration, analog signals swing from GND to V+, and the device maintains rail-to-rail capability, 2.5Ω max on-resistance, and TTL/CMOS logic compatibility via the dedicated VL pin.
What is the off-isolation performance of MAX4663CWE at 1MHz?
The MAX4663CWE provides –56dB minimum off-isolation at 1MHz under dual-supply conditions (V+ = +15V, V− = –15V), measured per Figure 5 in the datasheet. This value degrades at higher frequencies due to capacitive coupling, and isolation falls below –20dB above ~300MHz - confirming its suitability for DC–10MHz precision routing, not RF switching.
How does the VL pin function in MAX4663CWE, and can it be tied to V+?
The VL pin sets the logic threshold independently of analog supplies. It must be connected to a stable voltage between (GND – 0.3V) and (V+ + 0.3V). While tying VL to V+ works for +5V logic, doing so eliminates TTL compatibility and raises VINH to ~V+, risking overdrive if control signals are lower voltage. For guaranteed 0.8V/2.4V thresholds, VL should be fixed at +5V - as specified in all electrical characteristics tables.
