Product details
Overview
MAX4601CWE from Maxim Integrated is a quad SPST analog switch with four normally closed (NC) channels, designed for rail-to-rail signal routing in precision analog systems. It delivers 2.5Ω max on-resistance, 0.5Ω max RON match between channels, and 2.5nA max off-leakage at +85°C, operating from single +4.5V to +36V or dual ±4.5V to ±20V supplies. It is used in automatic test equipment for reed relay replacement where low distortion and high reliability are critical.
For engineers reviewing the MAX4601CWE datasheet, MAX4601CWE pinout, MAX4601CWE application, or MAX4601CWE equivalent, key selection criteria include guaranteed RON flatness (0.5Ω max), TTL/CMOS-compatible logic thresholds (+0.8V/+2.4V), 16-pin Wide SO package compatibility, and NC-switch topology for fail-safe signal path closure.
Technical Context
The MAX4601CWE implements CMOS transmission-gate architecture with matched P- and N-channel devices per channel, enabling rail-to-rail analog signal handling across its full ±15V dual-supply or +12V single-supply operating range. Its digital control inputs feature fixed +0.8V low and +2.4V high thresholds-ensuring robust logic interfacing without level-shifting when powered from ±15V or +12V.
Each of the four NC switches exhibits tightly controlled dynamic parameters: 160ns typical turn-on time, 170ns typical turn-off time, 20pC charge injection, and –60dB crosstalk at 1MHz. Off-isolation reaches –56dB (dual supply) and –59dB (single supply), validated over –40°C to +85°C temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω maximum - ensures minimal voltage drop and signal attenuation in low-level analog paths |
| RON Match | 0.5Ω maximum - enables precise gain matching in multi-channel instrumentation front-ends |
| RON Flatness | 0.5Ω maximum over full signal range - maintains consistent channel gain across ±10V input swing |
| Off-Leakage Current | 2.5nA maximum at +85°C - preserves accuracy in high-impedance sensor interfaces and sample-hold circuits |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - supports industrial, avionics, and telecom power architectures |
| Logic Thresholds | +0.8V low / +2.4V high - guarantees direct interface with TTL and CMOS logic without external biasing |
| ESD Protection | >2000V per Method 3015.7 - enhances board-level robustness in handling and automated assembly |
Pinout & Package
MAX4601CWE is housed in a 16-pin Wide SO (SOIC-W) package, 7.5mm body width, 1.27mm pitch, with exposed pad not present. Pin 1 is marked by notch or dot; pin count and layout conform to JEDEC MS-013.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs - active-low logic drives NC closure; compatible with 0V/5V or ±15V referenced signals |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal path entry/exit points for each NC switch |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog outputs - conduct to COM when IN = 0V; open when IN ≥ +2.4V |
| 4 | V− | Negative analog supply - tied to GND for single-supply operation; sets lower rail for bipolar signal handling |
| 5 | GND | Digital ground reference - separate from analog supply pins to minimize noise coupling into switching paths |
| 12 | VL | Logic supply input - accepts 2.7V to 5.5V; decouples logic threshold generation from analog V+/V− rails |
| 13 | V+ | Positive analog supply - defines upper signal rail; supports up to +36V for high-voltage test system integration |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Signal Handling | Supports analog signals from V− to V+ without clipping - essential for full-scale audio, sensor, and DAC output routing |
| Guaranteed RON Match | 0.5Ω max mismatch between any two channels - enables accurate differential signal switching in instrumentation amplifiers |
| Low Charge Injection | 20pC typical - minimizes voltage glitch in sample-and-hold and multiplexed ADC front-ends |
| TTL/CMOS-Compatible Inputs | +0.8V/+2.4V thresholds - eliminates need for level shifters when interfacing with microcontrollers or FPGAs |
| Four NC Switches | Fail-safe default-closed topology - maintains signal continuity during power loss or logic fault conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1411BRUZ | Quad SPST, NO configuration; 1.8Ω RON; requires VL = V+; no NC option | Preferred where default-open behavior is required; unsuitable for fail-safe closed-path designs | Select ADG1411BRUZ only if NC functionality is unnecessary and lower RON justifies redesign for NO topology. |
| TS5A3157DCUR | Single SPDT, 0.75Ω RON, 5V-only supply; SC70-6 package; no dual/rail-to-rail support | Applicable only in low-voltage, space-constrained, single-channel designs - not a functional or pinout substitute | TS5A3157DCUR serves compact 3.3V/5V signal routing but cannot replace MAX4601CWE's quad NC, wide-supply, or rail-to-rail capability. |
Compared with ADG1411BRUZ and TS5A3157DCUR, the MAX4601CWE uniquely provides quad NC topology with guaranteed rail-to-rail operation across ±20V and +36V supplies - making it irreplaceable in fail-safe test and avionics signal routing where default closure and wide dynamic range are mandatory.

FAQ
What is the operating temperature range for the MAX4601CWE?
The MAX4601CWE is specified for 0°C to +70°C ambient operation. This commercial-grade temperature range is confirmed in the Ordering Information table and Electrical Characteristics sections of the datasheet. The 'C' suffix in MAX4601CWE explicitly denotes the 0°C to +70°C grade, distinct from the 'E' grade (–40°C to +85°C). All electrical parameters-including RON, leakage, and timing-are guaranteed across this full range.
Does the MAX4601CWE support single-supply operation?
Yes, the MAX4601CWE supports single-supply operation from +4.5V to +36V. In this mode, V− must be connected to GND, while V+ supplies the positive rail and VL may be tied to a 2.7V–5.5V logic supply. The datasheet confirms performance metrics-including 2.5Ω RON and 2.5nA off-leakage-at +12V single supply, with input voltage ranges and logic thresholds fully maintained.
How does the NC (normally closed) configuration of the MAX4601CWE affect system behavior during power loss?
The MAX4601CWE's NC configuration ensures all four switches remain conductive (COM–NC path closed) when INx = 0V or unpowered. During power loss or logic reset, the switches default to closed state-maintaining signal continuity in safety-critical paths such as sensor monitoring or backup audio routing. This fail-safe behavior is intrinsic to the device's internal architecture and requires no external components.
Can the MAX4601CWE handle bipolar analog signals?
Yes, the MAX4601CWE handles true bipolar analog signals from V− to V+ when operated from dual supplies (e.g., ±15V). Its rail-to-rail design allows input signals spanning the full supply range without clipping or distortion. The datasheet validates RON flatness, leakage, and switching performance across ±10V differential swings under dual-supply conditions.
What is the logic polarity relationship between INx and NCx closure in the MAX4601CWE?
In the MAX4601CWE, an INx logic low (≤ +0.8V) closes the corresponding NCx switch (COMx ↔ NCx conductive), while an INx logic high (≥ +2.4V) opens it. This active-low control is fixed and non-invertible-confirmed by the Truth Table and Pin Configuration diagrams. No external inversion is needed; standard microcontroller GPIO outputs can drive INx directly.
