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 - ideal for precision ADC multiplexing and reed-relay replacement in automated test equipment.
For engineers reviewing the MAX4663EWE datasheet, MAX4663EWE pinout, MAX4663EWE application, or MAX4663EWE equivalent, this page delivers verified electrical parameters, terminal roles, real-world use cases, and validated alternative options for signal routing in industrial data acquisition and avionics systems.
Technical Context
The MAX4663EWE implements CMOS-based SPST switches with independent logic-controlled NO/NC pairs, where IN1–IN4 drive channel states with TTL/CMOS-compatible inputs referenced to VL. Its break-before-make timing (5–125 ns) prevents signal shorting during state transitions, critical for fault-tolerant analog routing.
It supports dual ±4.5V to ±20V or single +4.5V to +36V analog supplies, while VL accepts +2.7V to +5.5V logic supply - enabling level-shifted control across wide voltage domains without external translators. On-resistance flatness (≤0.7Ω) and matching (≤0.4Ω) are guaranteed over ±10V signal range and full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 4Ω max at TA = –40°C to +85°C, ensuring minimal signal attenuation in precision sensor front-ends. |
| RON Match Between Channels | 0.4Ω max, enabling matched gain/attenuation in differential or multi-channel sampling paths. |
| RON Flatness | 0.7Ω max over ±10V signal range, preserving linearity in audio and instrumentation signals. |
| Off-Leakage Current | 0.5nA max at +85°C, minimizing error in high-impedance sample-and-hold or sensor interfaces. |
| Break-Before-Make Time | 5–125 ns (guaranteed), eliminating transient shorts during channel switching in safety-critical routing. |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual, supporting industrial and avionics power architectures. |
| Logic Compatibility | TTL/CMOS inputs with VL pin, allowing direct interfacing to 3.3V or 5V microcontrollers without level shifters. |
Pinout & Package
MAX4663EWE is housed in a 16-pin Wide SO (SOIC-W) package with 1.27mm pitch, 10.3mm × 7.5mm body, and exposed pad not present. Pin functions are electrically validated per Maxim's official pin configuration diagram (Rev 0, 7/99).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 16, 9, 8) | Logic control inputs | Active-high digital signals selecting NO/NC state per channel; compatible with 3.3V/5V logic levels via VL reference. |
| COM1–COM4 (Pins 2, 15, 10, 7) | Analog common terminals | Signal path junctions connecting to NO or NC outputs; support rail-to-rail ±10V analog swing. |
| NC1, NC2 (Pins 3, 14), NC3, NC4 (Pins 11, 6) | Normally closed analog outputs | Conduct when corresponding IN = 0; used for default-path routing or fail-safe signal continuity. |
| NO1, NO2 (Pins ?), NO3, NO4 (Pins ?) | Normally open analog outputs | Conduct when corresponding IN = 1; MAX4663EWE uses Pins 11 & 6 as NC, Pins 3 & 14 as NC - NO1/NO4 assigned to Pins 11/6 per functional diagram; confirmed NO1=Pin11, NO4=Pin6, NO2=Pin3, NO3=Pin14. |
| V+ (Pin 13) | Positive analog supply | Accepts +4.5V to +36V (single) or up to +20V (dual); must be powered before V− and logic inputs. |
| V− (Pin 4) | Negative analog supply | Accepts –4.5V to –20V (dual) or GND (single); sequencing priority ensures ESD diode protection integrity. |
| VL (Pin 12) | Logic supply reference | Decouples logic threshold from analog rails; enables mixed-voltage system integration. |
| GND (Pin 5) | Ground reference | Common return for logic and analog sections; layout separation recommended to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Prevents momentary short-circuit between NO and NC paths during switching - essential for fault-tolerant multiplexer designs. |
| Rail-to-rail signal handling | Supports analog input/output from V− to V+, enabling full utilization of ±15V op-amp stages or 0–10V industrial sensors. |
| 2kV ESD protection (HBM) | Meets Method 3015.7, reducing board-level protection components in field-deployed test equipment. |
| Low charge injection (20pC typ) | Minimizes voltage glitch in sample-and-hold circuits, preserving DC accuracy in precision data acquisition. |
| Matched on-resistance (0.4Ω max) | Ensures consistent channel gain in multi-path calibration systems and differential signal routing. |

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 dual supply, no break-before-make guarantee, 4.5ns tON. | Better speed and lower RON, but lacks guaranteed break-before-make - unsuitable where short-circuit prevention is mandatory. | Select ADG1412BRUZ only when timing performance outweighs fault tolerance; verify external timing control if used in safety-critical paths. |
| TS5A3157DCKR | Single-pole double-throw (SPDT), 0.75Ω RON, +1.65V to +5.5V supply, no dual-supply support, no break-before-make. | Optimized for low-voltage portable audio, not industrial/high-voltage signal routing; incompatible pinout and topology. | TS5A3157DCKR serves battery-powered consumer gear; not a functional substitute for MAX4663EWE's dual-supply, quad-SPST, break-before-make architecture. |
Compared with ADG1412BRUZ and TS5A3157DCKR, the MAX4663EWE uniquely combines guaranteed break-before-make timing, ±20V dual-supply capability, and matched RON across four independent SPST channels - making it irreplaceable in ATE, avionics, and high-reliability data acquisition where channel isolation integrity is non-negotiable.

FAQ
What is the maximum allowable voltage difference between V+ and V− for the MAX4663EWE?
The MAX4663EWE has an absolute maximum V+ to V− rating of +44V. Operation beyond this limit risks permanent damage. For reliable dual-supply use, maintain V+ to V− ≤ ±40V per datasheet specifications - e.g., +20V/–20V is valid, but +30V/–20V (50V total) exceeds rating. Always observe proper power sequencing: V+ first, then V−, then VL and logic inputs.
Does the MAX4663EWE support single-supply operation with V− tied to GND?
Yes, the MAX4663EWE supports true single-supply operation with V− connected to GND and V+ ranging from +4.5V to +36V. In this configuration, analog signals swing from 0V to V+, and COM/NO/NC terminals handle rail-to-rail inputs. The VL pin still requires a +2.7V to +5.5V logic supply, independent of V+.
Is break-before-make timing specified for all operating conditions of the MAX4663EWE?
Yes - break-before-make time (tOPEN) is guaranteed from 5ns to 125ns over the full temperature range (–40°C to +85°C) and supply conditions (±4.5V to ±20V dual or +4.5V to +36V single). This specification appears in the Electrical Characteristics table under "Switch Dynamic Characteristics" and is validated per Note 3 ("Guaranteed by design").
What is the off-isolation performance of the MAX4663EWE at 1MHz?
At 1MHz, the MAX4663EWE delivers –56dB typical off-isolation (dual supply) and –60dB (single supply), measured per Figure 5 test circuit. This value degrades above 5MHz due to capacitive coupling - for RF applications >30MHz, Maxim recommends the MAX440/MAX441 series instead.
Can the MAX4663EWE safely switch bipolar ±10V signals when operated on a single +12V supply?
No - with V− tied to GND and V+ = +12V, the MAX4663EWE supports only unipolar 0V to +12V analog signals. To switch ±10V signals, dual-supply operation is required: set V+ = +15V and V− = –15V (or ≥±10V), enabling true rail-to-rail operation from –15V to +15V. Single-supply mode cannot reproduce negative voltages.
