Product details
Overview
MAX365ESE+T 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 paths. It delivers <85Ω on-resistance (max), <2Ω channel-to-channel matching, <10pC charge injection, <4nA off-leakage at +85°C, and sub-170ns turn-off time. It operates from ±4.5V to ±20V bipolar or +10V to +30V single supply, supporting test equipment and military radio front-ends.
For engineers reviewing the MAX365ESE+T datasheet, MAX365ESE+T pinout, MAX365ESE+T application, or MAX365ESE+T equivalent, key selection criteria include guaranteed on-resistance flatness (∆9Ω max), ESD tolerance >2000V, CMOS/TTL logic compatibility, and verified performance across -40°C to +85°C industrial temperature range.
Technical Context
The MAX365ESE+T implements four independent SPST NO switches using Maxim's 44V silicon-gate process, enabling rail-to-rail analog signal handling up to ±15.5V with minimal distortion. Its low charge injection (<10pC) and flat on-resistance ensure accurate sample-and-hold operation without droop or settling error.
Switching is controlled by CMOS-compatible logic inputs referenced to VL (5V), with separate V+ and V− supplies decoupled from logic rails. The device maintains tight on-resistance matching (<2Ω) and flatness only under bipolar-supply operation, as explicitly specified in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (max) | <85Ω - ensures minimal voltage drop and power loss in signal paths up to ±15.5V analog swing |
| On-resistance match | <2Ω between channels - enables precise gain/phase matching in multi-channel instrumentation |
| Charge injection | <10pC - prevents voltage step errors in sample-and-hold and multiplexed ADC front-ends |
| Off-leakage (85°C) | <4nA - maintains signal integrity in high-impedance sensor interfaces and battery-operated systems |
| Turn-off time | <170ns - supports fast switching in communication system TDD and PBX line scanning |
| Supply range | ±4.5V to ±20V or +10V to +30V - allows flexible biasing in mixed-signal systems with legacy ±15V or modern unipolar rails |
| ESD rating | >2000V HBM - provides robust handling during board assembly and field service without external protection |
Pinout & Package
MAX365ESE+T is housed in a 16-pin narrow SOIC package (SOICN) with standard 0.150" width, JEDEC MS-012 compliant, and exposed pad connected to V+ per datasheet layout guidance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 2, 10, 11) | Logic control input | CMOS/TTL-compatible digital enable lines; low = switch open (NO), high = closed |
| COM1–COM4 (Pins 3, 6, 14, 15) | Analog common terminal | Signal source or sink node shared across each SPST switch; bidirectional current path |
| NO1–NO4 (Pins 4, 7, 12, 13) | Normally open analog terminal | Open-circuit when INx = low; connects to COMx only when INx = high; no internal pull-up/down |
| V+ (Pin 13) | Positive supply voltage | Bias rail for analog path; substrate connection point; must be ≥ |V−| for proper operation |
| V− (Pin 4) | Negative supply voltage | Bias rail for analog path; sets lower bound of rail-to-rail signal range; not GND-referenced |
| GND (Pin 5) | Ground reference | Logic ground return; isolated from analog supplies; used only for VL and input logic reference |
| VL (Pin 12) | Logic supply voltage | Defines logic threshold; connect to +5V for TTL compatibility or to V+ for CMOS-level inputs |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports continuous analog signals from V− to V+ (e.g., ±15.5V), eliminating clipping in wide-dynamic-range systems |
| Guaranteed on-resistance flatness | ∆9Ω max over full analog range - preserves linearity in precision gain-setting and filter-switching applications |
| Low power consumption | 35µW typical - enables use in portable and battery-backed instrumentation without thermal derating |
| High off-isolation | 60dB at +25°C - suppresses crosstalk between active and inactive channels in dense multiplexer layouts |
| Fast switching with matched timing | Turn-on <250ns, turn-off <170ns - enables synchronous sampling across all four channels with <80ns skew |

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 | 4-channel SPST NO, 44V supply rating, but higher on-resistance (120Ω typ) and no guaranteed flatness spec | Lacks ∆9Ω flatness guarantee and <2Ω matching; unsuitable for precision gain-switching | Select when cost sensitivity outweighs precision matching requirements and leakage <10nA is acceptable |
| TS5A3157DCKR | Single-channel SPST NO, 5.5V max supply, 0.75Ω on-resistance, but only rated to +85°C and no bipolar operation | Not pin-compatible; requires four devices plus level-shifting for same functionality | Choose only for low-voltage, space-constrained PCBs where ±15V operation is unnecessary |
Compared with ADG444BRUZ and TS5A3157DCKR, MAX365ESE+T uniquely combines guaranteed on-resistance matching, flatness, bipolar supply support, and industrial temperature grade in a single 16-pin SOIC-enabling direct replacement in legacy military and test equipment without redesign.

FAQ
What is the maximum analog signal voltage range supported by the MAX365ESE+T?
The MAX365ESE+T supports rail-to-rail analog signals from V− to V+, with absolute maximum ratings of ±44V on V+ and V−. Under standard ±15V operation, it reliably handles ±15.5V signals, as confirmed in the Electrical Characteristics table and Typical Operating Characteristics graphs.
Does the MAX365ESE+T require external protection diodes for overvoltage conditions?
No-external diodes are optional. The MAX365ESE+T features >2000V HBM ESD rating and built-in protection against overvoltage stress. However, if strict sequencing cannot be guaranteed, two series diodes on V+ and V− (as shown in Figure 1) reduce analog range by 1V but preserve all key parameters including on-resistance and leakage.
Can the MAX365ESE+T operate from a single +12V supply?
Yes. The MAX365ESE+T supports unipolar operation from +10V to +30V. When using +12V, connect V− to GND, set VL to +5V for TTL compatibility, and ensure analog signals remain within 0V to +12V. On-resistance increases slightly versus bipolar mode, but remains within datasheet limits (≤160Ω max).
Is the on-resistance matching specification valid under single-supply operation?
No. The datasheet explicitly states that on-resistance matching (<2Ω) and flatness (∆9Ω max) are guaranteed only under bipolar-supply operation (e.g., ±15V). Under unipolar conditions, these parameters are not tested or warranted-designers must verify performance empirically for critical matching applications.
What is the function of the exposed pad on the MAX365ESE+T SOIC package?
The exposed pad on the MAX365ESE+T SOIC package is electrically connected to V+ and serves as both a thermal dissipation path and a substrate tie. Per Maxim's package drawing and Application Hints, it must be soldered to a V+-referenced copper pour to ensure proper thermal performance and electrical stability-floating or grounding the pad violates the recommended layout.
