Product details
Overview
MAX4663CAE 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 - used in precision ADC multiplexing and reed relay replacement in test equipment.
For engineers reviewing the MAX4663CAE datasheet, MAX4663CAE pinout, MAX4663CAE application, or MAX4663CAE equivalent, this page delivers verified electrical specs, terminal roles, real-world use cases, and validated alternative parts for low-distortion analog routing in industrial and avionics systems.
Technical Context
The MAX4663CAE implements CMOS-based SPST switching with independent control of four channels: IN1/IN4 drive NO1/NO4 (normally open), while IN2/IN3 drive NC2/NC3 (normally closed). Its break-before-make timing is guaranteed at 5ns–125ns, preventing signal shorting 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 logic inputs across the full supply range. On-resistance matching (≤0.5Ω max) and flatness (≤0.5Ω max over ±10V signal range) ensure channel-to-channel signal integrity in multiplexed data acquisition.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures minimal voltage drop and power loss when routing ±10V analog signals at 10mA. |
| RON Match Between Channels | 0.5Ω max - enables precise gain/offset matching in multi-channel instrumentation amplifier front-ends. |
| RON Flatness | 0.5Ω max over ±10V - maintains consistent attenuation across full rail-to-rail input range, critical for audio and ADC sample-and-hold. |
| Break-Before-Make Time | 5ns–125ns - guarantees no overlap between NC and NO paths, eliminating transient shorts in safety-critical switching. |
| Off-Leakage Current | 0.5nA max at +85°C - preserves high-impedance node integrity in precision sensor interfaces and low-current measurement circuits. |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - supports wide-input industrial sensors and bipolar signal conditioning without level-shifting. |
| Logic Compatibility | TTL/CMOS via dedicated VL pin - allows direct interfacing with 3.3V or 5V microcontrollers regardless of analog supply voltage. |
Pinout & Package
MAX4663CAE is housed in a 16-pin SSOP (Shrink Small Outline Package) with 0.65mm pitch, 5.0mm × 6.2mm body size, and exposed pad not electrically connected. Pin 1 is marked by a dot or beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16, 9, 8 | IN1, IN2, IN3, IN4 | Digital control inputs: IN1/IN4 enable NO1/NO4; IN2/IN3 enable NC2/NC3 - active-high, referenced to VL. |
| 2, 15, 10, 7 | COM1, COM2, COM3, COM4 | Analog common terminals - bidirectional signal path shared between NC/NO pairs per channel. |
| 3, 6 | NC1, NC4 | Normally closed analog terminals - conduct to COM when corresponding IN = 0V; open when IN = high. |
| 14, 11 | NO2, NO3 | Normally open analog terminals - conduct to COM only when corresponding IN = high; isolated otherwise. |
| 4 | V− | Negative analog supply - connect to GND for single-supply operation; must be ≤ V+ − 0.3V. |
| 13 | V+ | Positive analog supply - supports up to +36V; sets upper rail for rail-to-rail analog signal range. |
| 12 | VL | Logic supply input - decouples logic threshold from analog rails, enabling mixed-voltage system integration. |
| 5 | GND | Ground reference - return path for logic and analog supplies; requires low-impedance PCB connection. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Prevents momentary shorting between NC and NO paths during switching - essential for fault-tolerant multiplexer designs. |
| Rail-to-rail analog signal handling | Supports input signals from V− to V+ without clipping - enables direct interface with ±15V op-amps and unbuffered sensors. |
| 2kV ESD protection (HBM) | Withstands electrostatic discharge during board handling and system integration - reduces field failure risk in automated test environments. |
| Low charge injection (20pC typ) | Minimizes voltage glitch on high-impedance nodes during switching - critical for sample-and-hold accuracy and DAC output settling. |
| Low off-isolation degradation | −56dB typical at 1MHz - maintains signal separation in multi-channel communication and RF-adjacent analog routing. |

FAQ
What is the operating temperature range for the MAX4663CAE?
The MAX4663CAE is rated for 0°C to +70°C ambient operation, as indicated by the "C" grade suffix in its part number. This commercial-grade temperature range suits benchtop test equipment, industrial control panels, and non-mission-critical embedded systems where extended thermal stress is not expected. The device's electrical specifications - including on-resistance, leakage, and switching times - are guaranteed across this full range.
Does the MAX4663CAE support both single- and dual-supply configurations?
Yes, the MAX4663CAE supports both configurations: +4.5V to +36V single supply (with V− tied to GND) or ±4.5V to ±20V dual supply. The separate VL pin allows independent logic-level referencing, ensuring TTL/CMOS compatibility regardless of analog rail choice. This dual-mode capability makes MAX4663CAE adaptable to legacy ±15V systems and modern wide-input industrial sensors alike.
How does the break-before-make function work in the MAX4663CAE?
The MAX4663CAE guarantees break-before-make timing of 5ns to 125ns between its NC and NO paths within each switched pair (e.g., NC2/NO2). This means the NC path fully opens before the NO path closes, eliminating any momentary short circuit. This behavior is process-guaranteed - not typical - and is critical in applications like redundant signal selection where unintended conduction could compromise safety or measurement integrity.
Can the MAX4663CAE handle rail-to-rail analog signals?
Yes, the MAX4663CAE handles rail-to-rail analog signals - meaning it passes voltages from V− to V+ without clipping or distortion. This is enabled by its CMOS architecture and charge-pump-assisted gate drive. For example, with V+ = +15V and V− = −15V, the device passes ±15V signals linearly, supporting direct interface with op-amps, transducers, and other bipolar analog circuitry without external level-shifting components.
What package type is used for the MAX4663CAE?
The MAX4663CAE uses a 16-pin SSOP (Shrink Small Outline Package) with 0.65mm lead pitch and a 5.0mm × 6.2mm body. This surface-mount package offers higher density than SOIC or DIP variants while maintaining manufacturability in standard SMT lines. Its thermal performance supports continuous operation at up to +70°C ambient, and the pinout matches industry-standard layout footprints for drop-in compatibility in existing designs.
