Product details
Overview
MAX365CPE from Maxim Integrated is a precision quad SPST analog switch with normally open (NO) configuration, designed for high-fidelity signal routing in precision instrumentation and test equipment. It delivers <85Ω on-resistance, <2Ω channel-to-channel matching, <10pC charge injection, rail-to-rail analog signal handling (±15V), and operates from ±4.5V to ±20V dual supplies or +10V to +30V single supply.
For engineers reviewing the MAX365CPE datasheet, MAX365CPE pinout, MAX365CPE application, or MAX365CPE equivalent, this page provides verified electrical specifications, DIP-16 pin mapping, real-world use cases in sample-and-hold and communication systems, and two validated alternative parts for design flexibility under varying temperature or packaging requirements.
Technical Context
The MAX365CPE implements four independent CMOS-controlled SPST switches with TTL/CMOS-compatible logic inputs and low-distortion analog paths. Its silicon-gate 44V process ensures stable on-resistance flatness (∆9Ω max) over full signal range and guarantees sub-4nA off-leakage at +85°C.
It supports both unipolar and bipolar operation without level-shifting circuitry; VL pin enables logic-level selection (TTL or CMOS), while V+ connects to substrate for enhanced latch-up immunity. Switches remain open during power-off, preventing unintended signal coupling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (max) | 85Ω - Ensures minimal signal attenuation and gain error in precision DC-coupled paths. |
| On-resistance match | <2Ω - Enables accurate channel balancing in differential or multi-path signal conditioning. |
| Charge injection | <10pC - Critical for low-glitch sample-and-hold performance and ADC front-end integrity. |
| Off-leakage (85°C) | <4nA - Maintains signal integrity in high-impedance sensor interfaces and battery-operated systems. |
| Switching time (tON/tOFF) | <250ns / <170ns - Supports multiplexing in medium-speed data acquisition up to ~1MHz. |
| Analog signal range | ±15V - Allows direct interfacing with industrial ±10V sensors and legacy instrumentation buses. |
| ESD rating | >2000V HBM - Provides robust handling during board assembly and field service without added protection. |
Pinout & Package
MAX365CPE is housed in a 16-pin plastic DIP package (0°C to +70°C operating range), with through-hole mounting and standard 0.3-inch body width. Pin 1 is marked by notch or dot; exposed pad is absent (unlike QFN variants).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | CMOS/TTL logic control inputs; active-high enables NO path (logic '1' = closed). |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - connect to signal source or load in SPST topology. |
| 3, 6, 11, 14 | NO1–NO4 | Normally open analog switch terminals - conduct only when corresponding INx = high. |
| 4 | V− | Negative supply rail - must be ≥ −20V; ties to substrate in bipolar mode for stability. |
| 5 | GND | Digital ground reference - separate from analog return unless system design mandates common ground. |
| 12 | VL | Logic supply input - set to +5V for TTL compatibility or tied to V+ for CMOS thresholds. |
| 13 | V+ | Positive supply rail - rated up to +30V; connects to substrate to suppress latch-up. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog handling | Supports signals from V− to V+ (e.g., ±15V), eliminating level-shifting in bipolar sensor interfaces. |
| Guaranteed on-resistance flatness | ∆9Ω max across full analog range - preserves linearity in precision gain stages and attenuators. |
| Low charge injection | <10pC - reduces sampling error and settling time in 12-bit+ data acquisition systems. |
| Bipolar/unipolar supply flexibility | Operates from ±4.5V to ±20V or +10V to +30V - simplifies power architecture in mixed-signal PCBs. |
| ESD-hardened construction | >2000V per Method 3015.7 - reduces need for external TVS diodes in ruggedized test equipment. |
Applications
| Sample-and-Hold Circuits | Communication Systems |
|---|---|
Use Scenario: Precision hold capacitor charging in 16-bit SAR ADC front-ends with low glitch energy. IC Role / Device Role / Timing Role: SPST switch isolating hold capacitor during acquisition phase; controlled by ADC's CONVST signal.

IC Role / Device Role / Timing Role: Normally open switch disconnecting bias networks and reference buffers during sleep mode. Use Value: 35µW quiescent power extends battery life; open-circuit behavior at power-off prevents backfeeding. |
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 |
|---|---|---|---|
| MAX365EPE | Extended temperature range (−40°C to +85°C); identical pinout and electrical specs. | Suitable for industrial outdoor or automotive under-hood environments where ambient exceeds +70°C. | Select MAX365EPE when operating temperature exceeds 70°C; no layout or firmware changes required. |
| ADG441BRZ | 44V supply rating, but higher typical RON (75Ω), no guaranteed flatness spec, and 25pC charge injection. | Acceptable for non-critical general-purpose switching where precision matching and low glitch are not required. | Choose ADG441BRZ only if cost sensitivity outweighs precision needs; verify leakage and settling in final design. |
Compared with MAX365CPE, MAX365EPE offers identical functionality with extended thermal tolerance, while ADG441BRZ trades guaranteed precision specs for broader vendor availability-making MAX365CPE optimal for metrology-grade designs demanding matched RON and sub-10pC injection.

FAQ
What is the maximum analog signal voltage range supported by the MAX365CPE?
The MAX365CPE supports analog signals from V− to V+, enabling rail-to-rail operation. With ±15V supplies, it handles ±15V signals; with +24V/0V single supply, it supports 0V to +24V. Absolute maximum ratings limit V+ to 44V and V− to −44V, but signal swing must stay within supply rails. This capability makes MAX365CPE ideal for interfacing with industrial ±10V sensors and legacy instrumentation standards.
Does the MAX365CPE require external pull-up or pull-down resistors on its logic inputs?
No, the MAX365CPE features CMOS/TTL-compatible inputs with guaranteed thresholds (VINH ≥ 2.4V, VINL ≤ 0.8V) and input currents below ±0.5µA across temperature. Its inputs are internally biased and do not require external resistors for proper logic recognition. This simplifies interface design with microcontrollers and FPGAs, and eliminates additional BOM items and board space in compact layouts using MAX365CPE.
How does the MAX365CPE behave when power supplies are removed?
When all supplies (V+, V−, VL, GND) are disconnected, all four switches in the MAX365CPE remain in the open (off) state due to internal circuit design. This fail-safe behavior prevents unintended signal conduction or backfeeding in powered-down subsystems-a critical feature in battery-operated systems and safety-critical instrumentation where MAX365CPE is deployed.
Can the MAX365CPE be used with a single +12V supply and TTL-level control signals?
Yes. Configure VL = +5V for TTL compatibility, tie V− to GND, and apply +12V to V+. The MAX365CPE then operates as a unipolar-switching device supporting 0V to +12V analog signals. Input logic thresholds remain valid, and on-resistance stays below 100Ω. This configuration is widely used in MAX365CPE-based data loggers and sensor concentrators where only positive supplies are available.
What is the thermal performance difference between MAX365CPE and MAX365EPE?
The MAX365CPE is rated for 0°C to +70°C operation, while MAX365EPE extends to −40°C to +85°C. Both share identical electrical specs and DIP-16 packaging, but MAX365EPE undergoes additional screening for wider temperature stability. For applications like outdoor test gear or factory-floor controllers where ambient may exceed 70°C, MAX365EPE is the qualified drop-in replacement-ensuring MAX365CPE-level performance across harsher conditions.
