Product details
Overview
MAX361ESE+T from Maxim Integrated is a precision quad SPST analog switch with normally closed (NC) configuration, designed for rail-to-rail signal routing in high-fidelity sample-and-hold and test equipment circuits. It delivers <85Ω max on-resistance, <3Ω channel-to-channel match, <9Ω on-resistance flatness over ±15V analog range, and <4nA off-leakage at +85°C.
For engineers reviewing the MAX361ESE+T datasheet, MAX361ESE+T pinout, MAX361ESE+T application, or MAX361ESE+T equivalent, this device is selected for low-charge-injection (<10pC), bipolar/uni-supply flexibility (±4.5V to ±20V or +10V to +30V), and guaranteed ESD robustness (>2000V) in industrial-grade timing-critical analog switching.
Technical Context
The MAX361ESE+T implements four independent NC switches fabricated in Maxim's 44V silicon-gate process, enabling rail-to-rail analog signal handling up to ±15.5V with CMOS/TTL-compatible logic inputs. Its architecture guarantees matched on-resistance and flat RON only under bipolar supply operation (±4.5V to ±20V), not unipolar mode.
Charge injection is tightly controlled at <10pC (typical 5pC), critical for precision sample-and-hold accuracy, while off-isolation exceeds 60dB at 1MHz and crosstalk remains below –100dB - both measured with 50Ω/5pF loads per channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15.5V with ±16.5V supplies - supports full-rail signal routing without clipping |
| Max On-Resistance | 85Ω at +25°C, 100Ω over –40°C to +85°C - ensures minimal gain error in precision gain-setting paths |
| On-Resistance Match | <2Ω between channels at +25°C - enables accurate differential signal switching without mismatch-induced offset |
| Charge Injection | <10pC - limits voltage glitch on hold capacitors to <10mV for 1nF load, preserving ADC sampling integrity |
| Off-Leakage Current | <4nA at +85°C - prevents measurable drift in high-impedance sample-and-hold nodes over temperature |
| Switching Speed | tON <250ns, tOFF <170ns (bipolar ±15V) - supports >1MHz multiplexing in automated test systems |
| ESD Rating | >2000V HBM - allows safe handling and board-level integration without additional protection circuitry |
Pinout & Package
MAX361ESE+T is housed in a 16-pin narrow SO package (5.3mm width), RoHS-compliant, with exposed pad connected to V+. Pin 12 is internally unconnected (N.C.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Logic Control Input | CMOS/TTL-compatible digital inputs controlling NC state of respective switches; low = ON (closed) for MAX361 |
| COM1–COM4 | Analog-Switch Drain Terminal | Common analog node per channel; connects to NC terminal when switch is active |
| NC1–NC4 | Analog-Switch Source Terminal | Normally closed analog output; tied internally to COM when IN = low |
| V+ | Positive Supply Voltage Input | Connected to substrate; must be ≥ |V−| + 1V and ≤ V− + 44V for safe operation |
| V− | Negative Supply Voltage Input | Supports split supplies down to ±4.5V; enables true bipolar signal handling |
| GND | Ground Reference | Logic ground reference; separate from analog signal ground in mixed-signal layouts |
| N.C. | No Connection | Pin 10 is not internally bonded - must be left floating or grounded per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Operates with analog signals from V− −2V to V+ +2V - eliminates level-shifting in ±15V systems |
| Guaranteed on-resistance flatness | ΔRON ≤9Ω over full analog range - maintains consistent gain/attenuation across input voltage swing |
| Bipolar/unipolar supply compatibility | Supports ±4.5V to ±20V or +10V to +30V - simplifies power architecture in mixed-voltage systems |
| Low charge injection | <10pC - reduces hold-mode settling error and minimizes droop in precision data acquisition |
| High off-isolation | >60dB at 1MHz - suppresses crosstalk between adjacent channels in multi-channel instrumentation |
Applications
| Sample-and-Hold Circuits | Test Equipment |
|---|---|
Use Scenario: Precision analog sampling in 16-bit data acquisition systems where hold capacitor charging must be glitch-free. IC Role / Device Role / Timing Role: Normally closed analog switch isolating amplifier output from hold capacitor during acquisition phase. Use Value: <10pC charge injection ensures sub-LSB error on 1nF hold capacitors, preserving DC accuracy over temperature. |
Use Scenario: Automated test fixture routing multiple DUT signals to shared measurement resources. IC Role / Device Role / Timing Role: Quad SPST switch enabling sequential channel selection without mechanical relays. Use Value: <250ns turn-on time supports >1MHz scan rates; <4nA leakage prevents false readings in high-Z probe paths. |
| Guidance and Control Systems | Battery-Operated Systems |

IC Role / Device Role / Timing Role: Analog multiplexer selecting between calibrated reference voltages and sensor inputs. Use Value: 35µW typical power consumption extends battery life; unipolar +10V to +30V support avoids dual-supply complexity. |
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 |
|---|---|---|---|
| MAX362ESE+T | Normally open (NO) configuration vs. MAX361ESE+T's NC; identical RON, leakage, and speed specs | Suitable where default-open safety state is required (e.g., power-off signal isolation) | Select MAX362ESE+T only if system logic requires active-high enable and failsafe open condition |
| ADG1412BRUZ | Higher RON (1.8Ω typ), wider supply (±15V/12V), but no guaranteed RON match or flatness spec | Better for low-RON needs but lacks channel matching - unsuitable for differential or ratiometric designs | Choose ADG1412BRUZ only when ultra-low on-resistance outweighs matching requirements |
Compared with MAX361ESE+T, MAX362ESE+T provides identical performance in NO configuration for fail-safe open applications, while ADG1412BRUZ trades guaranteed matching and flatness for lower absolute RON - making MAX361ESE+T uniquely suited for precision matched-channel routing.

FAQ
What is the operating temperature range for MAX361ESE+T?
The MAX361ESE+T is rated for –40°C to +85°C operation, validated across all electrical specifications including on-resistance, leakage, and switching times. This extended industrial temperature grade ensures reliability in outdoor instrumentation, automotive test rigs, and factory-floor control systems where ambient conditions exceed commercial-grade limits. The MAX361ESE+T maintains guaranteed RON match (<4Ω) and leakage (<4nA) across this full range.
Can MAX361ESE+T operate from a single +12V supply?
Yes, MAX361ESE+T supports unipolar operation from +10V to +30V. With +12V supply, its analog signal range is 0V to +12V, and on-resistance rises to 160Ω max at +25°C (200Ω over temperature). However, channel matching (<2Ω) and on-resistance flatness (<9Ω) are guaranteed only under bipolar supply conditions (±4.5V to ±20V); unipolar use sacrifices those precision features while retaining fast switching and low leakage.
How does the NC functionality of MAX361ESE+T behave during power loss?
MAX361ESE+T is a normally closed analog switch: when all supply rails are absent or logic inputs are inactive (INx = low), the COM–NC path remains conductive. This fail-safe behavior ensures uninterrupted signal continuity in safety-critical guidance systems. The NC state is inherent to internal FET topology - no external bias or pull-up is needed. Power sequencing (V+ first, then V−, then logic) preserves this behavior during startup/shutdown.
What is the maximum allowable voltage difference between V+ and V− for MAX361ESE+T?
The absolute maximum voltage difference between V+ and V− for MAX361ESE+T is 44V, per the Absolute Maximum Ratings table. Exceeding this risks permanent breakdown. For example, ±20V supplies (40V total) are valid, but +25V/–20V (45V) violates the rating. This 44V limit applies regardless of individual rail voltages - it is the differential stress across the substrate, which is tied to V+.
Is pin 10 (N.C.) on MAX361ESE+T required to be grounded or left floating?
Pin 10 of MAX361ESE+T is explicitly marked "N.C." (Not Internally Connected) in the datasheet pin description and functional diagrams. It must be left electrically floating - grounding or connecting it may induce parasitic coupling or violate internal isolation. Layout best practice treats N.C. pins as unused terminals: no trace, no solder mask opening, and no thermal or electrical connection in PCB design.
