Product details
Overview
The MAX361CPE+ from Maxim Integrated is a precision quad SPST analog switch with normally closed (NC) configuration, designed for high-fidelity signal routing in rail-to-rail analog paths. It delivers <85Ω on-resistance (max), <3Ω channel-to-channel match, <9Ω on-resistance flatness over signal range, <500pA leakage at +25°C, and sub-250ns turn-on time - enabling use in sample-and-hold circuits and test equipment where low distortion and fast settling are critical.
For engineers reviewing the MAX361CPE+ datasheet, MAX361CPE+ pinout, MAX361CPE+ application, or MAX361CPE+ equivalent, key selection considerations include its 16-pin plastic DIP package, bipolar (±4.5V to ±20V) or single-supply (+10V to +30V) operation, CMOS/TTL-compatible logic inputs, guaranteed charge injection <10pC, and ESD rating >2000V - all validated for 0°C to +70°C industrial operation.
Technical Context
The MAX361CPE+ implements four independent SPST switches fabricated in Maxim's 44V silicon-gate process, ensuring rail-to-rail analog signal handling up to ±15.5V with V+ = 16.5V and V− = −16.5V. Its architecture guarantees matched on-resistance (<2Ω typ at +25°C) and flat on-resistance (∆9Ω max) only under bipolar-supply operation, per datasheet Note 4.
Switching is controlled by non-inverted logic inputs (IN1–IN4), where logic low enables conduction between COMx and NCx terminals. Charge injection is tightly controlled at <10pC (typ 5pC), and off-isolation exceeds 60dB at 1MHz - critical for minimizing transient errors in precision sampling and multiplexing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On Resistance (RON) | <85Ω max at +25°C; ensures minimal signal attenuation and gain error in precision analog paths |
| On Resistance Match | <3Ω max between channels; enables accurate differential or ratiometric measurements without calibration |
| On Resistance Flatness | ∆9Ω max over full analog signal range; maintains consistent gain and linearity across ±15V input swing |
| Charge Injection | <10pC; limits voltage glitch on sampled hold capacitors, supporting ≤16-bit accuracy in S/H circuits |
| Off-Leakage Current | <4nA at +85°C; prevents DC error accumulation in high-impedance sensor interfaces and integrators |
| Supply Range | +10V to +30V (single) or ±4.5V to ±20V (bipolar); supports rail-to-rail signal switching without level-shifting |
| ESD Rating | >2000V per Method 3015.7; enhances robustness during board handling and system integration |
Pinout & Package
MAX361CPE+ uses a 16-pin plastic DIP package (0.300" wide), with pins arranged in dual in-line format and substrate tied to V+. Pin functions are electrically validated per Maxim's official pin description table and functional diagrams.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | CMOS/TTL-compatible logic inputs; low = closed path (COMx ↔ NCx) |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals; bidirectional current path shared with NCx |
| 3, 4, 11, 12 | NC1–NC4 | Normally closed analog switch terminals; internally connected to COMx when INx = low |
| 5 | GND | Ground reference for logic interface; isolated from analog signal path |
| 13 | V+ | Positive supply input; also connected to substrate - must be ≥ V− + 2V and ≤ V− + 44V |
| 6 | V− | Negative supply input; sets lower bound of analog signal range and defines off-state isolation |
| 14 | N.C. | No internal connection; must remain unconnected per datasheet |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports ±15.5V signal swing with ±16.5V supplies - eliminates need for external level shifters |
| Guaranteed low charge injection | <10pC ensures ≤1LSB error in 16-bit 1nF hold capacitors, critical for precision data acquisition |
| Bipolar and single-supply flexibility | Operates from ±4.5V to ±20V or +10V to +30V - simplifies power architecture in mixed-signal systems |
| Low power consumption | 35µW typical supply current enables use in battery-operated portable test gear and remote sensors |
| High off-isolation | 60dB at 1MHz minimizes crosstalk between adjacent channels in multi-channel multiplexers |

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 |
|---|---|---|---|
| MAX361EPE+ | Same functionality and pinout; extended temperature range (−40°C to +85°C) and same 16-pin plastic DIP package | Suitable for automotive or industrial environments requiring wider thermal tolerance | Select MAX361EPE+ when operating beyond 0°C to +70°C ambient, especially in uncontrolled enclosures |
| ADG441BRZ | Quad SPST, NO configuration; 44Ω max RON; 16-pin SOIC; requires dual supply but lacks guaranteed flatness spec | Not directly substitutable due to NO vs NC logic polarity and missing ∆9Ω flatness guarantee | Consider ADG441BRZ only if normally open behavior and SOIC packaging are acceptable trade-offs |
Compared with MAX361CPE+, MAX361EPE+ offers identical electrical performance with extended temperature capability, while ADG441BRZ provides SOIC packaging and lower on-resistance but requires redesign for logic polarity and lacks flatness assurance - making MAX361CPE+ optimal for NC-critical, thermally stable DIP-based designs.

FAQ
What is the maximum analog signal voltage range supported by the MAX361CPE+?
The MAX361CPE+ supports rail-to-rail analog signals from (V− − 2V) to (V+ + 2V), with absolute maximum ratings of V+ ≤ V− + 44V. Under ±15V supplies, it handles ±15.5V signals; under +12V single supply, it supports 0V to +12V - confirmed in Electrical Characteristics tables for both dual and single-supply conditions.
Is the MAX361CPE+ pin-compatible with the MAX362CPE+?
No, the MAX361CPE+ and MAX362CPE+ share identical pinout and package but differ in switch logic: MAX361CPE+ is normally closed (NC), while MAX362CPE+ is normally open (NO). Swapping them requires inverting control logic or redesigning the enable scheme - they are functionally complementary, not drop-in replacements.
Does the MAX361CPE+ require external pull-up or pull-down resistors on its logic inputs?
No. The MAX361CPE+ features CMOS/TTL-compatible inputs with guaranteed VIH = 2.4V and VIL = 0.8V, and input current ≤ ±500nA across temperature - allowing direct interfacing with microcontrollers, FPGAs, and logic gates without external biasing components.
Can the MAX361CPE+ operate from an unbalanced supply such as +24V and −5V?
Yes. The MAX361CPE+ supports unbalanced supplies as long as V+ − V− ≤ 44V and each supply remains within absolute maximum ratings. With +24V and −5V, the device operates correctly and retains rail-to-rail analog capability from −7V to +26V - per Applications Information section and Absolute Maximum Ratings table.
What is the thermal performance of the MAX361CPE+ in its plastic DIP package?
The MAX361CPE+ in 16-pin plastic DIP has a power dissipation limit of 842mW at +70°C, derating linearly at 10.53mW/°C above that temperature. At +25°C ambient, it safely dissipates >1W with proper PCB layout - verified in Absolute Maximum Ratings and confirmed by thermal resistance (θJA ≈ 119°C/W) calculations.
