Product details
Overview
MAX351ESE+T from Maxim Integrated is a precision quad SPST analog switch with four normally closed (NC) channels, designed for high-fidelity signal routing in rail-to-rail analog paths. It delivers <35Ω on-resistance (max), <2Ω channel-to-channel match, <3Ω on-resistance flatness over signal range, <250pA leakage at +25°C, and sub-175ns turn-on time - enabling use in sample-and-hold circuits and military-grade communications systems.
For engineers reviewing the MAX351ESE+T datasheet, MAX351ESE+T pinout, MAX351ESE+T application, or MAX351ESE+T equivalent, key selection criteria include guaranteed on-resistance matching across temperature, low charge injection (≤10pC), ESD tolerance >2000V, and dual-supply operation (±4.5V to ±20V) or single-supply operation (+10V to +30V) with CMOS/TTL logic compatibility.
Technical Context
The MAX351ESE+T implements four independent SPST switches with NC configuration, fabricated in Maxim's 44V silicon-gate process. Its architecture ensures matched on-resistance (<2Ω) and flatness (∆3Ω max) under bipolar supply conditions, while maintaining rail-to-rail analog signal handling up to ±15.5V.
It supports both unipolar (+10V to +30V) and bipolar (±4.5V to ±20V) supplies, with VL pin configurable for TTL (5V) or CMOS (tied to V+) logic interface. Input control signals are CMOS-compatible, minimizing loading, and internal protection diodes clamp analog terminals to V+ and V−.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On Resistance (max) | 35Ω - ensures minimal signal attenuation and gain error in precision signal paths |
| On Resistance Match | <2Ω between channels - enables accurate differential and ratiometric measurements |
| On Resistance Flatness | ∆3Ω max over full analog signal range - preserves linearity in audio, sensor, and instrumentation applications |
| Charge Injection | ≤10pC - reduces voltage glitch and settling error in sample-and-hold and multiplexed ADC front-ends |
| Off-Leakage Current | <6nA at +85°C - maintains signal integrity in high-impedance, battery-operated systems |
| ESD Rating | >2000V per Method 3015.7 - enhances robustness in field-deployed military and industrial equipment |
| Supply Range | Single: +10V to +30V; Bipolar: ±4.5V to ±20V - supports flexible power architecture including unbalanced rails |
Pinout & Package
MAX351ESE+T is housed in a 16-pin narrow SOIC package (width = 3.9mm, body size 9.9mm × 3.9mm), RoHS-compliant and tape-and-reel packaged for automated assembly.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16, 9, 8 | IN1–IN4 | CMOS/TTL-compatible digital control inputs; active-high logic controls NC switch state |
| 2, 15, 10, 7 | COM1–COM4 | Analog common terminals - connected to load or signal source; bidirectional current path |
| 3, 15, 11, 6 | NC1–NC4 | Normally closed analog terminals - shorted to COM when IN = low; open when IN = high |
| 4 | V− | Negative supply rail - must be connected for bipolar operation; tied to GND for single-supply mode |
| 5 | GND | Ground reference for logic and substrate - separate from analog ground but referenced to V− |
| 12 | VL | Logic supply voltage - set to 5V for TTL compatibility or tied to V+ for CMOS input thresholds |
| 13 | V+ | Positive supply rail - also connected to substrate; maximum 44V breakdown enables rail-to-rail analog swing |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports VCOM, VNC signals from V− to V+ (±15.5V typical), eliminating level-shifting in wide-dynamic-range systems |
| Guaranteed on-resistance flatness | ∆3Ω max over full analog range ensures consistent gain/attenuation across input voltage - critical for precision instrumentation |
| Low charge injection | ≤10pC minimizes transient voltage spikes during switching - essential for low-glitch sample-and-hold and data acquisition |
| Bipolar and unipolar supply flexibility | Operates from ±4.5V to ±20V or +10V to +30V - simplifies design across test equipment, avionics, and portable systems |
| ESD-hardened architecture | Exceeds 2000V HBM - reduces field failure risk in handling-sensitive military and industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX352ESE+T | Four normally open (NO) configuration vs. MAX351ESE+T's NC topology; identical specs otherwise | Suitable where default-open signal path is required (e.g., safety-critical disconnect on power-up) | Select MAX352ESE+T only when fail-safe open-state behavior is mandated; not interchangeable without logic inversion. |
| ADG1412BRUZ | Higher on-resistance (1.8Ω typ), lower supply voltage range (±5V to ±22V), and no guaranteed on-resistance match spec | Better suited for general-purpose industrial I/O rather than precision metrology or military comms | Choose ADG1412BRUZ for cost-sensitive, non-ratiometric applications where channel matching is not critical. |
Compared with MAX351ESE+T, MAX352ESE+T provides complementary logic polarity but identical performance envelope, whereas ADG1412BRUZ trades guaranteed matching and ultra-low leakage for broader commercial availability and lower unit cost - making it viable only where precision matching and low-temperature leakage are secondary.

FAQ
What is the operating temperature range of the MAX351ESE+T?
The MAX351ESE+T is rated for operation from -40°C to +85°C, as confirmed by its "E" grade designation in the ordering information table. This extended industrial temperature range makes it suitable for deployment in automotive under-hood modules, avionics subsystems, and outdoor communications infrastructure where ambient thermal stress is significant. All electrical specifications - including on-resistance match and leakage - are guaranteed across this full range.
Can the MAX351ESE+T operate from a single +12V supply?
Yes, the MAX351ESE+T supports single-supply operation from +10V to +30V. When using +12V, connect V− to GND, tie VL to +5V for TTL compatibility, and ensure analog signals remain within 0V to +12V. The device retains all key specs - including <35Ω on-resistance and <175ns turn-on time - though dynamic performance may vary slightly versus bipolar operation per the Electrical Characteristics tables.
How does the MAX351ESE+T differ from the MAX351CSE+T?
The MAX351ESE+T and MAX351CSE+T share identical pinout, package (16-pin narrow SO), and functional design, but differ in temperature rating: MAX351ESE+T operates from -40°C to +85°C ("E" grade), while MAX351CSE+T is rated only from 0°C to +70°C ("C" grade). All guaranteed parameters - on-resistance match, charge injection, and leakage - apply across their respective temperature ranges, with no other electrical or mechanical distinction.
Is the MAX351ESE+T pin-compatible with the MAX353ESE+T?
No, the MAX351ESE+T is not pin-compatible with the MAX353ESE+T. Although both are 16-pin narrow SO devices, their pin functions differ: MAX351ESE+T has four NC terminals (pins 1, 4, 11, 14), while MAX353ESE+T allocates pins 1/4/11/14 as mixed NO/NC (two each). Swapping them requires PCB layout revision and logic-level revalidation due to differing truth tables and terminal assignments.
What is the maximum analog signal voltage the MAX351ESE+T can handle?
The MAX351ESE+T supports rail-to-rail analog signal handling from V− to V+, with absolute maximum ratings of V+ ≤ 44V and V− ≥ -44V relative to GND. In practice, with ±15V supplies, analog signals up to ±15.5V are permitted on COM/NC terminals. Exceeding V+ or V− triggers internal clamping diodes - so signal swing must stay within (V− − 0.3V) to (V+ + 0.3V) to avoid forward conduction and potential damage.
