Product details
Overview
MAX4663EAE+T 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 where channel isolation and low distortion are critical.
For engineers reviewing the MAX4663EAE+T datasheet, MAX4663EAE+T pinout, MAX4663EAE+T application, or MAX4663EAE+T equivalent, this page delivers verified electrical parameters, terminal roles, real-world use cases, and validated alternative parts for test equipment, audio routing, and avionics signal path design.
Technical Context
The MAX4663EAE+T 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 5–125ns, preventing momentary 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 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 (typ. 3Ω) - ensures minimal voltage drop and signal attenuation in precision analog paths |
| RON Match Between Channels | 0.4Ω max - enables matched gain/attenuation across multi-channel instrumentation |
| Break-Before-Make Time | 5–125ns - guarantees no overlap between NC and NO states, critical for safe signal routing |
| Off-Leakage Current | 0.01nA typ. at +25°C - preserves accuracy in high-impedance sensor or sample-and-hold circuits |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, avionics, and wide-range test equipment rails |
| Logic Compatibility | TTL/CMOS via dedicated VL pin - decouples logic threshold from analog supply, simplifying mixed-voltage system design |
| ESD Protection | >2kV per Method 3015.7 - enhances robustness in handling and automated assembly environments |
Pinout & Package
MAX4663EAE+T 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 present - suitable for space-constrained PCB layouts requiring thermal performance up to 571mW at +70°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; active-high logic drives NO/NC state transitions |
| 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 = 0V |
| 11, 14 | NO1, NO4 | Normally open analog terminals - conduct when corresponding IN = high |
| 4 | V− | Negative analog supply - tied to GND for single-supply operation |
| 13 | V+ | Positive analog supply - sets upper rail for rail-to-rail analog signal swing |
| 12 | VL | Logic supply reference - enables fixed 0.8V/2.4V thresholds regardless of V+/V− |
| 5 | GND | Ground reference for logic and substrate - must be low-impedance return path |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Prevents signal shorting during channel switching - essential for fault-tolerant multiplexing in safety-critical systems |
| Rail-to-rail analog signal handling | Supports input signals from V− to V+ without clipping - preserves full dynamic range in ADC front-ends |
| 0.7Ω max RON flatness | Maintains consistent gain/attenuation across ±10V signal range - reduces harmonic distortion in audio and instrumentation |
| 2.5Ω max on-resistance | Minimizes insertion loss and self-heating in high-current analog paths (±200mA continuous) |
| TTL/CMOS-compatible control with VL pin | Enables direct interfacing with 3.3V or 5V microcontrollers without level-shifting - reduces BOM count |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG465BRUZ | Single-supply only (+3V to +36V); no break-before-make guarantee; 4.5Ω RON max | Lacks dual-supply flexibility and deterministic switching sequence - unsuitable for ±15V avionics or relay-replacement safety checks | Select when cost sensitivity outweighs need for guaranteed break-before-make and dual-rail support |
| TS5A3157DCKR | Lower voltage range (1.65V to 5.5V); 0.75Ω RON typ.; no ESD rating specified beyond JEDEC Class 2 | Restricted to low-voltage portable/audio systems - cannot interface with industrial ±15V or +24V signal chains | Choose for battery-powered consumer gear where ultra-low RON and small SC70 package are prioritized |
Compared with MAX4663EAE+T, ADG465BRUZ offers broader single-supply compatibility but lacks guaranteed break-before-make and dual-rail operation, while TS5A3157DCKR delivers lower on-resistance at 5V but fails to meet industrial or avionics voltage and reliability requirements.

FAQ
What is the maximum allowable voltage difference between V+ and V− for MAX4663EAE+T?
The absolute maximum rating specifies V+ to V− must not exceed +44V. This allows safe operation across the full dual-supply range (±4.5V to ±20V = 40V total), with 4V margin for transient spikes. Exceeding this risks permanent damage to internal protection diodes and switch transistors in the MAX4663EAE+T.
Does MAX4663EAE+T support single-supply operation with V− tied to GND?
Yes - MAX4663EAE+T fully supports single-supply mode: connect V− to GND, apply +4.5V to +36V to V+, and route analog signals from 0V to V+. All specifications including RON, leakage, and switching times remain valid per the single-supply electrical characteristics table in the datasheet for MAX4663EAE+T.
Is the break-before-make timing guaranteed for all four channels of MAX4663EAE+T simultaneously?
Yes - the MAX4663EAE+T guarantees break-before-make timing (5–125ns) for its two NO/NC pairs (IN1/NO1/NC2 and IN4/NO4/NC3), as confirmed in the truth table and dynamic characteristics section. This applies independently per pair, ensuring no overlap even during concurrent control transitions.
What is the typical charge injection value for MAX4663EAE+T, and how does it affect sample-and-hold circuits?
MAX4663EAE+T exhibits 20pC typical charge injection (Q), measured with VCOM = ±10V and VNO/VNC = ±10V. In sample-and-hold applications, this induces a voltage step error on the hold capacitor; for a 10nF capacitor, the error is ~2mV - requiring careful layout and guarding to maintain 12-bit+ accuracy in the MAX4663EAE+T implementation.
Can MAX4663EAE+T operate with VL = 3.3V while V+ = +24V and V− = GND?
Yes - the VL pin accepts 0.3V below GND to 0.3V above V+, so 3.3V is well within range when V+ = +24V. This enables direct interfacing with 3.3V microcontrollers while maintaining full analog performance; logic thresholds remain fixed at VIN_H = 2.4V and VIN_L = 0.8V regardless of V+ level in the MAX4663EAE+T.
