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 accurate sample-and-hold and guidance system signal switching.
For engineers reviewing the MAX361CPE datasheet, MAX361CPE pinout, MAX361CPE application, or MAX361CPE equivalent, key selection criteria include guaranteed bipolar supply operation (±4.5V to ±20V), 2000V ESD rating, low charge injection (<10pC), and compatibility with precision test equipment and battery-operated systems requiring stable analog switching performance.
Technical Context
The MAX361CPE implements four independent SPST switches with NC logic polarity, fabricated using Maxim's 44V silicon-gate process to ensure rail-to-rail analog signal handling up to ±15.5V. Its CMOS-compatible control inputs drive internal transmission gates without external level-shifting, while matched on-resistance and flat RON across voltage range minimize gain error in multiplexed instrumentation paths.
Charge injection is tightly controlled at <10pC (typ), critical for low-distortion sampling in data acquisition systems. The device supports both dual-supply (±4.5V to ±20V) and single-supply (+10V to +30V) operation, with leakage currents specified down to <4nA at +85°C and guaranteed off-isolation >60dB at 1MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (max) | 85Ω - ensures minimal signal attenuation and voltage drop in precision analog paths |
| On-resistance match | <3Ω between channels - enables accurate channel-to-channel signal ratio matching |
| Analog signal range | ±15.5V with ±16.5V supplies - supports true rail-to-rail input/output swing |
| Turn-on time (max) | 250ns - allows fast multiplexing in real-time control and test equipment |
| Charge injection (max) | 10pC - reduces sampling pedestal error in precision S/H circuits |
| Off-leakage (max) | 4nA at +85°C - maintains signal integrity in high-impedance sensor interfaces |
| ESD rating | >2000V HBM - enhances robustness in manufacturing and field environments |
Pinout & Package
MAX361CPE 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 located at the top-left corner when viewed from the top with notch or dot orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | CMOS/TTL-compatible logic inputs controlling NC switch state (low = ON) |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - connected to load or signal source |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog switch terminals - conduct when INx = low |
| 4 | V− | Negative supply rail - required for bipolar operation; connect to GND for unipolar use |
| 5 | GND | Ground reference - used as return path for logic and supply currents |
| 12 | V+ | Positive supply rail - also tied to substrate; must be ≥ |V−| + 10V for full analog range |
| 10, 11, 12, 13 | N.C. | No internal connection - electrically isolated; no routing or loading required |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog handling | Supports ±15.5V signal swing with ±16.5V supplies - eliminates level-shifting in wide-dynamic-range systems |
| Guaranteed RON flatness | Δ9Ω max over full analog range - preserves linearity in precision gain/attenuation stages |
| Low charge injection | <10pC - minimizes hold-mode voltage step in sample-and-hold amplifiers |
| Bipolar/unipolar flexibility | Operates from ±4.5V to ±20V or +10V to +30V - simplifies power architecture across industrial and portable designs |
| High off-isolation | >60dB at 1MHz - suppresses crosstalk between adjacent switched channels |

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 |
|---|---|---|---|
| ADG441BRZ | Quad SPST, NO configuration; 40Ω typical RON; requires dual supply only (±5V to ±20V); no guaranteed RON match spec | Not suitable for NC-critical fail-safe paths; better for low-RON unipolar signal routing where channel matching is secondary | Select ADG441BRZ when lower on-resistance is prioritized over NC logic and inter-channel matching. |
| TS5A3154DCUR | Single-supply only (1.65V to 5.5V); 0.75Ω typical RON; 10-bit DAC-grade linearity; no bipolar support or ESD >2kV rating | Targeted at low-voltage portable instrumentation; incompatible with ±15V industrial signal chains | Choose TS5A3154DCUR only for battery-powered 3.3V/5V systems requiring ultra-low RON, not for legacy ±15V test or aerospace designs. |
Compared with ADG441BRZ and TS5A3154DCUR, the MAX361CPE uniquely combines NC logic, guaranteed RON matching, bipolar/unipolar flexibility, and 2000V ESD in a DIP package-making it irreplaceable in safety-critical analog routing where fail-safe closure and signal fidelity are mandatory.

FAQ
What is the maximum analog signal voltage range supported by the MAX361CPE?
The MAX361CPE supports an analog signal range of ±15.5V when operated with ±16.5V supplies, enabling true rail-to-rail signal handling. This specification is guaranteed under bipolar supply conditions (±4.5V to ±20V) and is critical for preserving full dynamic range in instrumentation and control applications using the MAX361CPE.
Does the MAX361CPE require external pull-up or pull-down resistors on its logic inputs?
No, the MAX361CPE features CMOS/TTL-compatible logic inputs with input current ≤ ±500nA across the full temperature range, eliminating the need for external biasing resistors. This simplifies PCB layout and ensures reliable switching with standard microcontroller GPIOs driving the MAX361CPE control lines.
Can the MAX361CPE operate from a single +12V supply?
Yes, the MAX361CPE supports unipolar operation from +10V to +30V. When using +12V, V− must be connected to GND, and the analog signal range becomes 0V to +12V. On-resistance increases to 160Ω (max) under these conditions, as confirmed in the single-supply electrical characteristics table for the MAX361CPE.
What is the guaranteed on-resistance match between channels for the MAX361CPE?
The MAX361CPE guarantees on-resistance matching of <3Ω between any two channels at +25°C, and <4Ω over the full 0°C to +70°C operating range. This parameter is explicitly tested and specified in the MAX361CPE datasheet's "On Resistance Match Between Channels" row under dual-supply conditions.
Is the MAX361CPE pin-compatible with the MAX362CPE?
No, the MAX361CPE and MAX362CPE share identical pinouts but differ in switch logic: MAX361CPE uses normally closed (NC) switches, while MAX362CPE uses normally open (NO). Swapping them without circuit redesign will invert signal path behavior-e.g., a path that conducts at logic low with MAX361CPE will remain open under the same condition with MAX362CPE.
