Product details
Overview
MAX4636EUB from Maxim Integrated is a dual single-pole/double-throw (SPDT) CMOS analog switch with 4Ω max on-resistance at +5V, 14ns max turn-on time, and rail-to-rail signal handling from +1.8V to +5.5V supply. It features independent channel control, break-before-make switching, and low crosstalk (−67dB at 1MHz), making it suitable for audio routing and low-voltage data-acquisition systems.
For engineers reviewing the MAX4636EUB datasheet, MAX4636EUB pinout, MAX4636EUB application, or MAX4636EUB equivalent, key selection considerations include guaranteed on-resistance flatness (1Ω max), logic-level tolerance up to +5.5V regardless of V+, and µMAX package compatibility with space-constrained PCB layouts.
Technical Context
The MAX4636EUB implements two independently controlled SPDT switches using CMOS process technology, supporting bidirectional analog signal routing across the full supply rail range. Its break-before-make architecture prevents momentary shorting between NO and NC paths during state transitions.
Logic inputs accept 0V to +5.5V signals irrespective of V+ voltage, enabling direct interfacing with 5V logic while operating from +3.3V or +2.5V supplies. On-resistance remains stable over temperature and signal voltage, with flatness specified at 1Ω max under +5V conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (max) | 4Ω at +5V supply - enables low-loss signal routing in precision analog paths |
| Turn-on time (max) | 14ns - supports high-speed multiplexing in sampling and communications circuits |
| Rail-to-rail operation | Signal range spans GND to V+ - preserves full dynamic range without clipping |
| Crosstalk | −67dB at 1MHz - minimizes interference between adjacent switched channels |
| Off-isolation | −65dB at 1MHz - ensures effective channel separation when off |
| Supply voltage range | +1.8V to +5.5V - compatible with battery-powered and mixed-voltage systems |
| Logic input tolerance | 0V to +5.5V - eliminates need for level shifters when interfacing with 5V controllers |
Pinout & Package
The MAX4636EUB is housed in a 10-pin µMAX package (3.0mm × 3.0mm × 0.8mm, no exposed pad), optimized for high-density PCB layouts. Pin numbering follows standard top-view orientation with Pin 1 marked by a dot or notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1 | Logic control input for Switch 1 | Active-high control: drives COM1 to NO1 when high, to NC1 when low |
| NO1 | Normally open terminal of Switch 1 | Connected to COM1 only when IN1 = high; isolated otherwise |
| GND | Ground reference | Return path for supply and logic; must be low-impedance for noise control |
| NO2 | Normally open terminal of Switch 2 | Connected to COM2 only when IN2 = high; isolated otherwise |
| IN2 | Logic control input for Switch 2 | Independent active-high control for second SPDT switch |
| COM2 | Common terminal of Switch 2 | Signal I/O node shared between NO2 and NC2 paths |
| NC2 | Normally closed terminal of Switch 2 | Connected to COM2 only when IN2 = low; isolated when high |
| V+ | Positive supply input | Single supply rail powering both analog and digital sections (+1.8V to +5.5V) |
| NC1 | Normally closed terminal of Switch 1 | Connected to COM1 only when IN1 = low; isolated when high |
| COM1 | Common terminal of Switch 1 | Signal I/O node shared between NO1 and NC1 paths |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed on-resistance match | 0.2Ω max between channels - ensures balanced signal path performance in differential or dual-channel applications |
| On-resistance flatness | 1Ω max over full signal range at +5V - maintains consistent gain and linearity across input voltage swing |
| Low charge injection | 2pC typical - reduces glitch energy in sample-and-hold and precision switching applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4635EUB | Inverted logic control (IN_ low = connect to NO_; IN_ high = connect to NC_) | Same pinout and electrical specs, but requires complementary logic drive | Select when system logic naturally aligns with inverted control or when mixing with MAX4636EUB in same design requires polarity management |
| ADG723BRMZ | Higher on-resistance (6.5Ω typ), slower switching (25ns tON), different pinout (10-lead MSOP) | Compatible function but not drop-in; requires layout revision and recalibration for RON impact | Consider only if ADI ecosystem preference or long-term availability outweighs performance trade-offs |
Compared with MAX4635EUB, the MAX4636EUB offers non-inverted logic for simplified microcontroller interface; compared with ADG723BRMZ, it delivers faster switching, lower RON, and tighter matching-critical for high-fidelity audio and precision data acquisition where signal path consistency is essential.

FAQ
What is the maximum supply voltage rating for the MAX4636EUB?
The MAX4636EUB has an absolute maximum supply voltage (V+) of +6V. Operation above +5.5V is not recommended, as the device is characterized and guaranteed for reliable performance from +1.8V to +5.5V. Exceeding +6V may cause permanent damage per the Absolute Maximum Ratings table in the datasheet.
Does the MAX4636EUB support rail-to-rail analog signal operation?
Yes, the MAX4636EUB supports true rail-to-rail analog signal handling: its analog inputs (COM_, NO_, NC_) operate from GND to V+ across the full specified supply range. This allows undistorted passage of signals spanning the entire supply voltage, critical for preserving dynamic range in audio and sensor interfaces.
How does the logic polarity of MAX4636EUB differ from MAX4635EUB?
The MAX4636EUB uses non-inverted logic: IN_ = high connects COM_ to NO_, and IN_ = low connects COM_ to NC_. In contrast, the MAX4635EUB uses inverted logic (IN_ = low → NO_, IN_ = high → NC_). Both share identical pinout and electrical specs except for this control polarity difference.
Can the MAX4636EUB interface directly with 5V logic while powered from a 3.3V supply?
Yes, the MAX4636EUB logic inputs (IN1, IN2) tolerate voltages up to +5.5V regardless of V+ level. When powered from +3.3V, it accepts standard 5V TTL/CMOS logic levels without external level shifters-enabling seamless integration with legacy or mixed-voltage controller systems.
What is the guaranteed on-resistance flatness specification for MAX4636EUB at +5V?
The MAX4636EUB guarantees on-resistance flatness of 1Ω maximum over the full analog signal range (GND to V+) when operated at +5V supply. This parameter reflects the peak-to-peak variation in RON across the signal swing and ensures consistent gain and linearity in precision analog paths.
