Product details
Overview
The MAX365CSE from Maxim Integrated is a precision quad single-pole single-throw (SPST) analog switch with normally open (NO) configuration, designed for high-fidelity signal routing in precision instrumentation and communication systems. It delivers <85Ω on-resistance, <2Ω channel-to-channel matching, <10pC charge injection, <4nA off-leakage at +85°C, and rail-to-rail analog signal handling up to ±15V with ±4.5V to ±20V dual supplies.
For engineers reviewing the MAX365CSE datasheet, MAX365CSE pinout, MAX365CSE application, or MAX365CSE equivalent, this device is selected for low-distortion multiplexing in sample-and-hold circuits, battery-operated test equipment, and military-grade guidance systems where leakage, switching speed, and signal integrity are critical.
Technical Context
The MAX365CSE implements four independent CMOS-controlled SPST switches with TTL/CMOS-compatible logic inputs and operates across dual-supply (±4.5V to ±20V) or single-supply (+10V to +30V) configurations. Its silicon-gate process ensures guaranteed on-resistance flatness (∆9Ω max) and matched tracking (<2Ω) over temperature and signal range.
Switching performance is characterized by turn-on time <250ns and turn-off time <170ns at ±15V, with off-isolation >60dB and crosstalk >100dB. Charge injection is tightly controlled at <10pC, enabling accurate sampling in precision data acquisition without significant hold-step error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (max) | 85Ω - Ensures minimal signal attenuation and gain error in voltage-mode signal paths. |
| On-resistance match | <2Ω - Enables precise channel-to-channel gain and offset matching in multi-channel mux designs. |
| Charge injection | <10pC - Limits hold-step error in sample-and-hold circuits to sub-mV levels with typical 1nF hold capacitors. |
| Off-leakage (max, +85°C) | 4nA - Maintains accuracy in high-impedance sensor interfaces and long-integration-time measurement systems. |
| Supply range | ±4.5V to ±20V dual or +10V to +30V single - Supports rail-to-rail analog signal swing up to ±15.5V. |
| Switching time (tON/tOFF) | <250ns / <170ns - Enables multiplexing of signals up to ~1MHz without significant settling degradation. |
| ESD rating | >2000V HBM - Provides robust handling during board assembly and field service without external protection. |
Pinout & Package
MAX365CSE is housed in a 16-pin narrow SOIC package (SOIC-N) with 150-mil body width, JEDEC MS-012 compliant, and features gull-wing leads with 1.27mm pitch. The exposed pad is absent - this is a standard plastic SOIC, not QFN.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | CMOS/TTL logic inputs controlling respective NO switches; active-high, no internal pull-up/down. |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - connected to load/sensor; bidirectional current path when switch closed. |
| 3, 6, 11, 14 | NO1–NO4 | Normally open analog switch outputs - only conduct to COM when corresponding IN = high. |
| 4 | V− | Negative supply rail - must be ≥ −2V below most negative analog signal to avoid latch-up. |
| 5 | GND | Digital ground reference - separate from analog return but tied at system star point. |
| 12 | VL | Logic supply input - set to 5V for TTL compatibility or tied to V+ for CMOS-level thresholds. |
| 13 | V+ | Positive supply rail - also connected to substrate; must be ≤44V above V− to prevent breakdown. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog operation | Supports full-swing signals from V− to V+ without clipping or distortion, critical for ±15V industrial sensors. |
| Guaranteed on-resistance flatness | ∆9Ω max over full analog range - eliminates gain nonlinearity in precision attenuator or programmable-gain amplifier paths. |
| Low charge injection | <10pC - reduces hold capacitor voltage step to <10mV with 1nF capacitor, enabling 12-bit+ sample-and-hold accuracy. |
| Bipolar/single-supply flexibility | Operates from ±4.5V to ±20V or +10V to +30V - simplifies power architecture in mixed-signal systems with legacy ±15V rails. |
| ESD-hardened design | >2000V per MIL-STD-883 Method 3015.7 - eliminates need for external ESD diodes in handheld or field-deployable equipment. |

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 |
|---|---|---|---|
| ADG444BRUZ | Higher on-resistance (120Ω typ), higher charge injection (25pC), but offers 12V single-supply-only operation. | Less suitable for ±15V rail-to-rail signal routing; better fit for low-voltage portable instrumentation. | Select ADG444BRUZ only if supply is strictly +12V and leakage tolerance >10nA is acceptable. |
| TS5A4624DCKR | Lower voltage rating (5.5V max), much lower on-resistance (0.5Ω), but limited to +5V operation and lacks bipolar support. | Applicable only in low-voltage digital I/O or audio switching; cannot replace MAX365CSE in industrial ±15V systems. | TS5A4624DCKR is viable only in battery-powered 3.3V/5V signal routing where rail-to-rail analog range is not required. |
Compared with ADG444BRUZ and TS5A4624DCKR, the MAX365CSE uniquely supports true bipolar ±20V operation with guaranteed low leakage and flat on-resistance - making it irreplaceable in high-precision, wide-supply industrial and defense applications.

FAQ
What is the maximum analog signal voltage range supported by the MAX365CSE?
The MAX365CSE supports rail-to-rail analog signals from V− to V+, with absolute maximum ratings allowing V+ up to 44V above V−. In standard ±15V operation, the usable analog range is ±15.5V - verified across the full 0°C to +70°C temperature range and guaranteed by design for both single- and dual-supply configurations.
Does the MAX365CSE require external pull-up or pull-down resistors on its logic inputs?
No, the MAX365CSE logic inputs (IN1–IN4) are CMOS/TTL compatible with built-in input threshold circuitry and do not require external biasing. Input leakage is specified at ±0.5µA max, and the device functions correctly with direct connection to FPGA or microcontroller GPIO pins operating at 3.3V or 5V logic levels.
Can the MAX365CSE operate with unbalanced supplies such as +24V and −5V?
Yes, the MAX365CSE supports unbalanced supplies - including +24V and −5V - as long as the total V+ to V− differential does not exceed 44V and each supply remains within its absolute maximum rating. This configuration maintains rail-to-rail analog signal capability from −5V to +24V, confirmed in the device's Electrical Characteristics tables.
What is the thermal performance of the MAX365CSE in narrow SOIC package?
The MAX365CSE in 16-pin narrow SOIC has a thermal resistance θJA of 115°C/W. At maximum continuous power dissipation of 696mW (at +70°C ambient), junction temperature rise is ~80°C - well within safe operating limits. Derating is 8.70mW/°C above +70°C, supporting reliable operation up to +125°C junction temperature.
How does the MAX365CSE behave when power is removed?
When all supplies (V+, V−, VL) are removed, the MAX365CSE switches enter a high-impedance open state - all NO terminals remain disconnected from their COM terminals. This fail-open behavior prevents unintended signal coupling during power sequencing or brownout conditions, as explicitly stated in the Applications Information section.
