Product details
Overview
MAX4601EPE+ 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 and low-distortion audio-signal routing.
For engineers reviewing the MAX4601EPE+ datasheet, MAX4601EPE+ pinout, MAX4601EPE+ application, or MAX4601EPE+ equivalent, key selection criteria include guaranteed RON flatness (0.5Ω max), TTL/CMOS-compatible logic thresholds (+0.8V/+2.4V), -40°C to +85°C industrial temperature range, and 16-pin plastic DIP package compatibility with legacy through-hole layouts.
Technical Context
The MAX4601EPE+ implements CMOS-based transmission-gate architecture with matched P- and N-channel MOSFETs per channel, enabling rail-to-rail analog conduction and symmetric on-resistance behavior across input voltage swing. Its control logic accepts standard TTL/CMOS levels independent of supply configuration.
It features integrated ESD protection (>2000V per Method 3015.7), low charge injection (20pC typ), and tightly controlled dynamic parameters: 160ns typ turn-on time and 170ns typ turn-off time at VCOM = 10V, RL = 100Ω, CL = 35pF. Off-isolation reaches -56dB at 1MHz, while crosstalk remains below -60dB between any two switches.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω maximum - ensures minimal signal attenuation and voltage drop in precision analog paths |
| RON Match | 0.5Ω maximum - enables accurate channel-to-channel signal balancing in multiplexed or differential applications |
| RON Flatness | 0.5Ω maximum over full signal range - maintains consistent gain and linearity across ±10V analog inputs |
| Off-Leakage Current | 2.5nA maximum at +85°C - preserves high-impedance node integrity in sample-and-hold or sensor front-ends |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports wide industrial and test-equipment power architectures |

| Operating Temperature | -40°C to +85°C - qualified for industrial-grade reliability in embedded and automated test environments |
Pinout & Package
MAX4601EPE+ uses a 16-pin plastic DIP (dual in-line package) with 0.3-inch body width and standard through-hole mounting. Pin spacing is 0.1 inch, compatible with legacy PCB footprints and socketing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; active-low logic turns ON NC path (logic "0" = closed) |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals; connect to signal source or load in SPST configuration |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals; conduct to COM when IN = 0V |
| 4 | V− | Negative analog supply rail; tied to GND for single-supply operation |
| 5 | GND | Digital ground reference; decoupling required near VL and supply pins |
| 12 | VL | Logic supply input; accepts 3V to 5V for TTL/CMOS interface compatibility |
| 13 | V+ | Positive analog supply rail; sets upper analog signal limit and RON performance |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for full-scale instrumentation and audio routing |
| Guaranteed RON flatness | 0.5Ω max variation across ±10V signal range - eliminates distortion in AC-coupled or wide-dynamic-range circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG465BRZ | Quad SPST NO, 4.5Ω max RON, -40°C to +85°C, 16-SOIC | Normally open topology requires inverted control logic; higher RON limits current drive capability | Select when NO default state is required and layout allows SOIC footprint |
| TS5A23157DGSR | Quad SPST NO, 0.9Ω max RON, +1.65V to +3.6V only, 10-pin VSSOP | Single-supply only, lower voltage range, smaller package - unsuitable for ±15V or high-voltage signal routing | Prefer for battery-powered portable instruments needing ultra-low RON at 3.3V logic |
Compared with ADG465BRZ and TS5A23157DGSR, MAX4601EPE+ uniquely provides NC default state, 2.5Ω RON at ±15V, and through-hole DIP packaging - making it optimal for industrial test hardware requiring fail-safe closure and legacy board compatibility.

FAQ
What is the default switch state of MAX4601EPE+?
The MAX4601EPE+ features four normally closed (NC) switches: each COM–NC path conducts when its corresponding IN pin is at logic low (≤0.8V). When IN is high (≥2.4V), the path opens. This fail-safe NC behavior makes MAX4601EPE+ ideal for safety-critical signal paths where continuity must be maintained during control loss or power-down events.
Can MAX4601EPE+ operate from a single +12V supply?
Yes, MAX4601EPE+ supports single-supply operation from +4.5V to +36V. With V+ = +12V and V− tied to GND, it delivers 4Ω typical RON and maintains rail-to-rail signal handling from 0V to +12V. Logic inputs remain TTL/CMOS-compatible via VL = +5V, and all electrical specifications-including 2.5nA max off-leakage at +85°C-are fully guaranteed.
Does MAX4601EPE+ require external protection diodes for overvoltage?
No-MAX4601EPE+ includes internal protection diodes on all analog pins (COM, NC, NO), clamping signals to V+ and V− rails. External diodes are unnecessary unless absolute maximum ratings risk being exceeded (e.g., transient spikes >±44V). The datasheet explicitly states that adding external diodes reduces signal range and is not recommended for single-supply use.
How does temperature affect RON in MAX4601EPE+?
RON in MAX4601EPE+ increases with temperature but remains tightly bounded: at V+ = +12V and VCOM = +10V, RON is 3Ω typ at -40°C, 3.5Ω typ at +25°C, and 4.2Ω typ at +85°C. The 0.5Ω max RON match and 0.5Ω max flatness are guaranteed across the full -40°C to +85°C range, ensuring predictable channel tracking in thermally varying environments.
Is MAX4601EPE+ pin-compatible with other MAX460x variants?
Yes-MAX4601EPE+, MAX4602EPE+, and MAX4603EPE+ share identical 16-pin plastic DIP pinouts and package dimensions. Only the switch configuration differs: MAX4601EPE+ is NC-only, MAX4602EPE+ is NO-only, and MAX4603EPE+ combines two NC and two NO channels. This allows drop-in replacement in existing layouts when logic polarity or default state requirements change.
