Product details
Overview
MAX4605CSE from Maxim Integrated is a quad, single-pole single-throw (SPST), normally open (NO) CMOS analog switch with 5Ω maximum on-resistance, 0.5Ω maximum on-resistance match between channels, and rail-to-rail signal handling capability across ±4.5V to ±20V dual supplies or +4.5V to +36V single supply. It delivers low 2.5nA max off-leakage at +85°C and supports TTL/CMOS-compatible control inputs - ideal for precision audio-signal routing in automated test equipment.
For engineers reviewing the MAX4605CSE datasheet, MAX4605CSE pinout, MAX4605CSE application, or MAX4605CSE equivalent, key selection criteria include guaranteed RON flatness (≤0.5Ω over signal range), charge injection (≤225pC), off-isolation (−62dB), and SOIC-16 package compatibility with industrial temperature-grade variants.
Technical Context
The MAX4605CSE implements four independent SPST NO switches using high-voltage CMOS process technology, enabling operation across wide analog supply rails while maintaining tight channel-to-channel RON matching (≤0.5Ω) and flatness (≤0.5Ω). Its logic interface accepts 0.8V/2.4V thresholds for robust TTL/CMOS compatibility under ±15V or +12V supply conditions.
Each switch features internal ESD protection (>2000V per Method 3015.7), rail-to-rail analog signal support, and low dynamic parameters: tON = 120ns (typ), tOFF = 130ns (typ), and crosstalk ≤−60dB at 1MHz - critical for low-distortion multiplexing in communication and avionics systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 5Ω max - ensures minimal voltage drop and signal attenuation in precision analog paths |
| RON Match | 0.5Ω max - enables matched gain/phase response across channels in differential or multi-path routing |
| RON Flatness | 0.5Ω max over full signal range - preserves linearity for ±10V signals without distortion |
| Off-Leakage Current | 2.5nA max at +85°C - maintains high-impedance isolation in battery-powered or high-precision sensor interfaces |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - supports legacy industrial and modern mixed-supply systems |
| Logic Thresholds | 0.8V low / 2.4V high - guarantees reliable switching with standard TTL/CMOS drivers without level-shifting |
| Charge Injection | 225pC max - limits transient glitches during switching in sample-and-hold or ADC front-end circuits |
Pinout & Package
MAX4605CSE is housed in a 16-pin narrow SOIC (SO/DIP) package with 1.27mm pitch, rated for 0°C to +70°C operation. The package supports surface-mount assembly and provides thermal performance up to 696mW at +70°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs for respective NO switches; TTL/CMOS-compatible with 0.8V/2.4V thresholds |
| 2, 7, 10, 15 | COM1–COM4 | Common analog terminals - connect to signal source or load in SPST configuration |
| 3, 6, 11, 14 | NO1–NO4 | Normally open analog outputs - conduct only when corresponding INx = HIGH |
| 4 | V− | Negative analog supply rail; tied to GND for single-supply operation |
| 5 | GND | Digital ground reference for logic interface and substrate bias |
| 12 | VL | Logic supply input - decouples digital switching noise from analog path; typically +5V |
| 13 | V+ | Positive analog supply rail - sets upper limit of rail-to-rail signal range |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for full-scale instrumentation amplifier outputs |
| Guaranteed RON match | ≤0.5Ω max between all four channels - enables precise gain-matching in multi-channel data acquisition |
| TTL/CMOS-compatible inputs | 0.8V/2.4V thresholds validated across full supply range - eliminates need for external level shifters |
| ESD protection | >2000V per Method 3015.7 - enhances reliability in handling-sensitive production and field environments |
| Low charge injection | 225pC max - reduces settling error in high-resolution sampling circuits and DAC output buffering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1414BRUZ | 4-channel SPST NO, 1.8Ω RON, ±15V supply, but requires VL = V+ and lacks separate logic supply pin | Better RON and bandwidth (170MHz), yet less flexible supply sequencing and higher cost | Prefer ADG1414BRUZ when ultra-low on-resistance and RF performance are critical; use MAX4605CSE where independent VL and proven industrial reliability are prioritized. |
| TS5A3157DCKR | Single-channel SPST NO, 0.75Ω RON, +1.65V to +5.5V only, SC70-6 package | Lower voltage, smaller footprint, but not quad-channel and incompatible with ±15V or high-voltage analog rails | Select TS5A3157DCKR for space-constrained, low-voltage portable designs; MAX4605CSE remains optimal for industrial/high-voltage quad-switching needs. |
Compared with ADG1414BRUZ and TS5A3157DCKR, the MAX4605CSE uniquely balances quad-channel integration, ±20V dual-supply operation, independent VL pin for noise isolation, and AEC-Q100-unqualified but field-proven reliability in harsh environments - making it the preferred choice for test equipment and avionics where supply flexibility and channel matching outweigh raw RON minimization.

FAQ
What is the maximum supply voltage rating for MAX4605CSE?
The MAX4605CSE supports absolute maximum analog supply ratings of V+ to GND = −0.3V to +44V and V− to GND = +0.3V to −44V, with recommended operating ranges of +4.5V to +36V (single supply) or ±4.5V to ±20V (dual supply). Exceeding these limits risks permanent damage due to internal diode clamping, as specified in the Absolute Maximum Ratings table of the MAX4605CSE datasheet.
Does MAX4605CSE support rail-to-rail analog signal operation?
Yes, the MAX4605CSE supports true rail-to-rail analog signal handling - signals at COM or NO pins can swing from V− to V+ without clipping or increased distortion. This is confirmed in the General Description and Electrical Characteristics sections, where input voltage range is specified as (V− − 0.3V) to (V+ + 0.3V) under normal operation, and verified across temperature and supply conditions.
What is the logic supply voltage (VL) requirement for MAX4605CSE?
The MAX4605CSE requires a dedicated logic supply voltage (VL) pin, typically connected to +5V, which powers the internal digital control circuitry independently from the analog supplies (V+ and V−). This separation minimizes digital switching noise coupling into analog paths and ensures stable logic thresholds (0.8V/2.4V) across varying analog rail conditions.
How does MAX4605CSE compare to MAX4604CSE in functionality?
The MAX4605CSE implements four normally open (NO) SPST switches, whereas the MAX4604CSE implements four normally closed (NC) switches. Their pinouts and electrical specs (RON, leakage, timing) are identical, but logic polarity is inverted: for MAX4605CSE, INx = HIGH enables conduction; for MAX4604CSE, INx = LOW enables conduction. This functional difference determines fail-safe behavior in system-level design.
Is MAX4605CSE pin-compatible with other packages in the same family?
Yes, the MAX4605CSE (16-pin narrow SOIC) shares identical pinout and functionality with MAX4605CPE (16-pin plastic DIP), MAX4605ESE (−40°C to +85°C SOIC), and MAX4605EPE (−40°C to +85°C DIP). All variants use the same SO/DIP pin configuration shown in the MAX4605 top-view diagram, enabling direct PCB footprint reuse across temperature grades and package types.
