Product details
Overview
MAX365CSE+ from Maxim Integrated is a precision quad SPST analog switch with normally open (NO) configuration, designed for high-fidelity signal routing in rail-to-rail analog systems. It delivers <85Ω on-resistance, <2Ω channel-to-channel matching, <10pC charge injection, <4nA off-leakage at +85°C, and 250ns turn-on time-enabling accurate sampling in test equipment and communication interfaces.
For engineers reviewing the MAX365CSE+ datasheet, MAX365CSE+ pinout, MAX365CSE+ application, or MAX365CSE+ equivalent, this page provides verified specifications, SOIC-16 pin mapping, real-world use cases in PBX and sample-and-hold circuits, and two validated alternative parts with documented functional and application-level differences.
Technical Context
The MAX365CSE+ implements four independent CMOS-controlled SPST switches with TTL/CMOS-compatible logic inputs and bipolar or single-supply operation (±4.5V to ±20V or +10V to +30V). Its silicon-gate architecture ensures flat on-resistance over full analog signal range (Δ9Ω max) and low distortion via guaranteed <10pC charge injection.
It supports rail-to-rail analog signal handling up to ±15.5V with 44V breakdown voltage, while maintaining sub-500pA leakage at +25°C and ESD robustness >2000V. Switching performance is characterized under dual-supply conditions with defined load (RL = 50Ω, CL = 5pF) and input edge rates (tr/tf < 20ns).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | <85Ω max - ensures minimal signal attenuation and gain error in precision gain-setting or multiplexing paths |
| On-Resistance Match | <2Ω between channels - critical for matched gain/phase in multi-channel instrumentation or balanced signal paths |
| Charge Injection | <10pC - limits voltage glitch in sample-and-hold circuits, preserving DC accuracy after switching |
| Off-Leakage Current | <4nA at +85°C - maintains high-impedance isolation in battery-operated or low-power sensor front-ends |
| Turn-On / Turn-Off Time | <250ns / <170ns - enables fast channel selection in automated test equipment and digital control loops |
| Analog Signal Range | ±15.5V - supports full-rail operation with ±15V supplies, eliminating level-shifting in industrial analog I/O |
| ESD Rating | >2000V HBM - enhances reliability during board handling and system integration without external protection |
Pinout & Package
MAX365CSE+ is housed in a 16-pin narrow SOIC (SO) package (JEDEC MS-012, 3.9mm body width), with exposed pad connected to V+ per manufacturer recommendation. Pin 1 is marked by notch or dot; pin numbering follows standard SOIC convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 2, 15, 16) | Logic control input | CMOS/TTL-compatible digital inputs controlling respective NO switches; low = open, high = closed |
| COM1–COM4 (Pins 3, 4, 13, 14) | Analog common terminal | Signal path hub per switch; connects to NO terminal when corresponding IN is high |
| NO1–NO4 (Pins 5, 6, 11, 12) | Normally open analog terminal | Open-circuit when IN = low; completes path to COM when IN = high |
| V+ (Pin 10) | Positive supply | Primary power rail; substrate connection point; must be ≥ |V−| for proper biasing |
| V− (Pin 9) | Negative supply | Enables bipolar operation; sets lower bound of analog signal range |
| GND (Pin 8) | Ground reference | Logic ground return; tied to 0V in single-supply mode |
| VL (Pin 7) | Logic supply voltage | Defines logic threshold: connect to +5V for TTL compatibility or to V+ for CMOS levels |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog handling | Supports signals from V− to V+ (±15.5V typical), eliminating need for external clamping or level shifters |
| Guaranteed on-resistance flatness | Δ9Ω max across full analog range ensures consistent gain/attenuation regardless of signal voltage |
| Low charge injection | <10pC minimizes hold-step error in precision sample-and-hold amplifiers and ADC front-ends |
| Bipolar or single-supply operation | Operates from ±4.5V to ±20V or +10V to +30V - simplifies power architecture in mixed-signal systems |
| ESD-hardened design | >2000V HBM rating reduces risk of field failure during assembly and end-use in harsh environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG441BRZ | Quad SPST NO switch; 40Ω max RON, 150ns tON, −40°C to +85°C grade only | Higher speed but narrower temp range; requires ±15V or +12V supply only | Select for faster switching where extended temperature range is not required |
| TS5A23157DGSR | Single-supply only (+1.65V to +5.5V); 0.9Ω RON, 25ns tON, but max analog range limited to VCC | Optimized for low-voltage portable designs; incompatible with bipolar or high-voltage rails | Select for battery-powered 3.3V/5V systems needing ultra-low RON and speed |
Compared with ADG441BRZ and TS5A23157DGSR, the MAX365CSE+ uniquely supports rail-to-rail analog signals up to ±15.5V with guaranteed flat on-resistance and low charge injection-making it the preferred choice for precision instrumentation and military-grade communication systems requiring wide dynamic range and DC stability.

FAQ
What is the maximum analog signal voltage range supported by the MAX365CSE+?
The MAX365CSE+ supports an analog signal range from V− to V+, with a maximum specified range of ±15.5V when operated from ±16.5V supplies. This rail-to-rail capability allows direct interfacing with ±15V op-amps and ADCs without level shifting. The device's 44V breakdown voltage ensures safe operation even with transient overvoltage conditions.
Does the MAX365CSE+ require separate logic and analog supplies?
Yes-the MAX365CSE+ has a dedicated VL pin for logic supply voltage, which can be set to +5V for TTL compatibility or tied to V+ for CMOS logic thresholds. This separation allows independent optimization of logic noise immunity and analog signal integrity, especially important in mixed-signal PCB layouts where digital switching noise must be isolated from sensitive analog paths.
Can the MAX365CSE+ operate from a single +12V supply?
Yes-the MAX365CSE+ supports single-supply operation from +10V to +30V. When using +12V, connect V− to GND, VL to +5V (for TTL) or +12V (for CMOS), and ensure analog signals remain within 0V to +12V. On-resistance increases slightly versus bipolar operation, but remains below 160Ω typical, and leakage stays under 500pA at +25°C.
What is the significance of the <2Ω on-resistance matching specification for the MAX365CSE+?
The <2Ω channel-to-channel on-resistance matching ensures uniform gain, attenuation, and time constants across all four switches-critical in applications like multi-channel data acquisition, differential signal routing, or programmable gain amplifiers. This tight matching eliminates calibration overhead and preserves signal fidelity in systems where relative channel accuracy matters more than absolute RON value.
How does the MAX365CSE+ handle power-off conditions?
When unpowered, all switches in the MAX365CSE+ remain in their normally open (NO) state-i.e., fully disconnected. This fail-safe behavior prevents unintended signal coupling or back-powering of upstream circuitry. However, analog terminals (COM/NO) must never exceed V+ or V− voltage ratings, even during power-down, to avoid latch-up or damage per Absolute Maximum Ratings.
