Product details
Overview
MAX4663EAE from Maxim Integrated is a quad SPST analog switch IC with two normally closed (NC) and two normally open (NO) 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 ADC multiplexing and reed-relay-replacement systems.
For engineers reviewing the MAX4663EAE datasheet, MAX4663EAE pinout, MAX4663EAE application, or MAX4663EAE equivalent, this page delivers verified electrical parameters, terminal roles, real-world use cases in test equipment and avionics, and validated alternative parts for signal-path redesigns requiring low RON, matched flatness, and leakage-controlled switching.
Technical Context
The MAX4663EAE implements CMOS transmission-gate architecture with independent logic-level control inputs (IN1–IN4), separate analog supply pins (V+, V−), and dedicated logic supply (VL) enabling TTL/CMOS compatibility across full voltage ranges. Its internal structure guarantees break-before-make timing of 5ns to 125ns between complementary NC/NO pairs (e.g., IN1/IN4 and IN2/IN3).
All four switches support rail-to-rail analog signals up to ±20V (dual) or 0V to +36V (single), with on-resistance flatness ≤0.7Ω over the full signal range and channel-to-channel RON match ≤0.4Ω (typ), critical for low-distortion multiplexing in data acquisition and audio routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 4Ω max at +25°C, +12V single supply - ensures minimal signal attenuation and gain error in precision sensor front-ends. |
| RON Match | 0.4Ω max between channels - enables accurate channel-to-channel signal balancing in multi-input ADC systems. |
| RON Flatness | 0.7Ω max over full signal range - maintains consistent gain and linearity across ±10V analog inputs. |
| Off-Leakage Current | 0.01nA typ at +25°C - prevents DC error accumulation in high-impedance sample-and-hold circuits. |
| Break-Before-Make Time | 5–125ns (guaranteed) - eliminates momentary short-circuit risk when switching between NC and NO paths. |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - supports industrial, avionics, and test-equipment power architectures. |
| Logic Compatibility | TTL/CMOS inputs with VL pin - allows direct interfacing to 3.3V or 5V microcontrollers without level-shifting. |
Pinout & Package
MAX4663EAE 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 connected internally - suitable for automated SMT assembly and thermal management in dense PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; active-high logic drives NO channels ON / NC channels OFF. |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal path shared between NC and NO contacts. |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - conduct to COM when IN = low (MAX4663 has NC1, NC2, NO3, NO4). |
| 12 | VL | Independent logic supply input - decouples digital interface from analog rails for noise immunity. |
| 4 | V− | Negative analog supply - tied to GND for single-supply operation; sets lower signal rail limit. |
| 13 | V+ | Positive analog supply - defines upper signal rail; supports up to +36V or ±20V. |
| 5 | GND | Ground reference for logic and substrate - must be low-impedance return path for leakage-sensitive nodes. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Ensures no overlap conduction between NC and NO paths in dual-throw configurations - critical for fault-tolerant signal routing. |
| Rail-to-rail signal handling | Supports analog inputs spanning full V− to V+ range without clipping - preserves dynamic range in ±15V op-amp interfaces. |
| 2kV ESD protection (HBM) | Withstands electrostatic discharge during handling and board insertion - reduces field failure in automated test environments. |
| Low charge injection (20pC typ) | Minimizes voltage glitch on sampled nodes - essential for high-resolution SAR ADC front-end switching. |
| Matched on-resistance flatness | 0.7Ω max variation across signal range - maintains THD < −90dB in audio-signal routing applications. |
Applications
| ADC Multiplexing | Avionics 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 |
|---|---|---|---|
| ADG1414BRUZ | Quad SPST, 1.8Ω RON, ±15V supply, no break-before-make guarantee, 16-TSSOP package. | Lower RON but lacks guaranteed break-before-make - unsuitable where NC/NO coexistence must be avoided. | Select when ultra-low on-resistance dominates over switching safety; verify layout for charge-injection sensitivity. |
| TS5A3159DBVR | Single-pole double-throw (SPDT), 0.75Ω RON, +1.65V to +5.5V only, no dual-supply support, SOT-23-6. | Not quad, not dual-supply capable, and lacks NC/NO pairing - requires multiple devices and level-shifting for equivalent function. | Use only in low-voltage, space-constrained consumer designs where ±15V operation is unnecessary. |
Compared with MAX4663EAE, ADG1414BRUZ offers lower resistance but no break-before-make assurance, while TS5A3159DBVR provides compact SPDT switching at low voltage only - neither replicates the MAX4663EAE's integrated dual-mode (NC+NO), wide-supply, and guaranteed safe-transition capability in a single 16-pin SSOP.

FAQ
What is the guaranteed break-before-make time for MAX4663EAE?
The MAX4663EAE guarantees a break-before-make interval of 5ns minimum to 125ns maximum between complementary NC/NO pairs (e.g., IN1/IN4 and IN2/IN3). This specification is tested and ensured across the full operating temperature range (−40°C to +85°C) and supply conditions, preventing momentary short-circuits during state transitions - a key differentiator from generic analog switches. The MAX4663EAE datasheet Figure 3 and Electrical Characteristics table explicitly define this parameter.
Can MAX4663EAE operate from a single +12V supply?
Yes, MAX4663EAE supports single-supply operation from +4.5V to +36V. With V− tied to GND and V+ at +12V, it delivers 4Ω max on-resistance, 0.01nA typical off-leakage, and full rail-to-rail analog switching (0V to +12V). The VL pin must be supplied with a compatible logic voltage (e.g., +3.3V or +5V) to ensure TTL/CMOS-compatible control - confirmed in the Single-Supply Electrical Characteristics table on page 4 of the MAX4663EAE datasheet.
What is the maximum analog signal voltage range supported by MAX4663EAE?
MAX4663EAE handles analog signals from V− to V+ - supporting ±20V with dual supplies or 0V to +36V with single supply. When operated at ±15V, its specified signal range is ±10V; at +12V single supply, it passes 0V to +10V without distortion. This rail-to-rail capability is guaranteed across temperature and documented in the Absolute Maximum Ratings and Electrical Characteristics sections - critical for interfacing with op-amps and sensors operating at full supply rails.
Does MAX4663EAE require external protection diodes for overvoltage tolerance?
No, MAX4663EAE includes internal ESD protection diodes rated for >2kV HBM, and its absolute maximum ratings allow V+ to GND up to +44V and V− to GND down to −44V. External diodes (as shown in Figure 1 of the datasheet) are optional and only recommended if power-supply sequencing cannot be controlled - for example, in systems where V− powers up before V+. The MAX4663EAE itself does not require them for normal operation within datasheet limits.
How does MAX4663EAE's on-resistance match impact multi-channel data acquisition?
MAX4663EAE guarantees ≤0.4Ω on-resistance mismatch between channels (ΔRON), ensuring gain tracking errors remain below 0.02% in 4-channel multiplexed ADC front-ends. This tight matching, combined with ≤0.7Ω flatness over signal range, minimizes differential nonlinearity and inter-channel crosstalk - directly improving ENOB in 16-bit+ systems. These values are measured and specified in the Dual-Supply Electrical Characteristics table (page 3) and confirmed in Typical Operating Characteristics plots.
