Product details
Overview
MAX4600CPE+ from Maxim Integrated is a dual SPST CMOS analog switch with one normally closed (NC) and one normally open (NO) channel, designed for rail-to-rail signal routing in precision analog systems. It delivers 1.25Ω max on-resistance, 0.25Ω max RON match between channels, and 0.3Ω max RON flatness over ±10V signal range, supporting test equipment and communication system signal path switching.
For engineers reviewing the MAX4600CPE+ datasheet, MAX4600CPE+ pinout, MAX4600CPE+ application, or MAX4600CPE+ equivalent, key selection criteria include dual-supply compatibility (±4.5V to ±20V), TTL/CMOS logic thresholds (+0.8V/+2.4V), low 2.5nA off-leakage at +85°C, and 16-pin plastic DIP package suitability for through-hole prototyping and industrial control interfaces.
Technical Context
The MAX4600CPE+ implements complementary MOSFET switch pairs per channel, enabling bidirectional rail-to-rail analog conduction without signal clipping. Its dual independent control inputs (IN1, IN2) drive separate NC/NO configurations - Switch 1 is NC (ON when IN1 = 0), Switch 2 is NO (ON when IN2 = 1) - allowing asymmetric signal path control in multiplexer or relay-replacement topologies.
Internal level-shifting circuitry ensures logic compatibility across supply ranges: with VL = +5V, IN1/IN2 accept 0.8V/2.4V thresholds under +12V single supply or ±15V dual supplies. The device guarantees ESD protection >2kV (HBM, Method 3015.7) and operates from 0°C to +70°C, matching the C-grade temperature specification of the CPE+ variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 1.25Ω max - enables low-voltage drop (<12.5mV at 10mA) and minimal signal attenuation in precision sensor or audio paths. |
| RON Match | 0.25Ω max - ensures matched gain/attenuation between dual channels for differential or ratiometric measurements. |
| RON Flatness | 0.3Ω max over ±10V - maintains consistent channel resistance across full analog input range, critical for linearity in data acquisition. |
| Off-Leakage Current | 2.5nA max at +85°C - minimizes error current in high-impedance sensor front-ends or sample-and-hold circuits. |
| Supply Range | ±4.5V to ±20V dual or +4.5V to +36V single - supports legacy industrial ±15V rails and modern wide-range power architectures. |
| Logic Thresholds | +0.8V low / +2.4V high - guarantees direct interface with 5V TTL/CMOS controllers without level shifters. |
| Turn-On/Off Time | 150ns / 200ns typical - suitable for <1MHz multiplexing in automated test equipment and serial communication switching. |
Pinout & Package
MAX4600CPE+ uses a 16-pin plastic DIP (dual in-line package) with 0.300" body width, compatible with standard through-hole PCB assembly and socket-based evaluation. Pin spacing is 0.100", and lead finish is matte tin.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | No Connect (N.C.) | Not internally connected; tie to GND to improve off-isolation and reduce crosstalk. |
| 2, 7 | COM1 / COM2 | Analog common terminals - bidirectional signal ports connecting to NC1/NO1 and NC2/NO2 respectively. |
| 4 | V− | Negative analog supply - grounded for single-supply operation; sets lower rail for rail-to-rail signal handling. |
| 5 | GND | Digital and analog reference ground - must be low-impedance node shared with VL and V− return paths. |
| 9, 16 | NC1 / NC2 | Normally closed analog terminals - conduct to COM1/COM2 when respective INx = 0 (low). |
| 11, 14 | NO1 / NO2 | Normally open analog terminals - conduct to COM1/COM2 when respective INx = 1 (high). |
| 12 | VL | Logic supply input - powers internal level shifter; typically +5V, independent of analog supply rails. |
| 13 | V+ | Positive analog supply - defines upper rail; supports up to +36V in single-supply mode. |
| 1, 3, 6, 8, 10, 15 | IN1 / IN2 | Digital control inputs - IN1 controls NC1/COM1, IN2 controls NO2/COM2; active-low for NC, active-high for NO. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for ±10V industrial sensor interfaces and audio line-level routing. |
| Guaranteed RON match | 0.25Ω max difference between channels - enables accurate differential switching in instrumentation amplifiers and ADC front-ends. |
| TTL/CMOS-compatible inputs | +0.8V/+2.4V thresholds with VL = +5V - eliminates external logic translators when interfacing with microcontrollers or FPGAs. |
| ESD protection >2kV | HBM-rated per JEDEC 3015.7 - enhances robustness during board handling and field deployment in test fixtures. |
| Low charge injection (40pC) | Minimizes voltage glitch on sampled nodes - critical for precision sample-and-hold and switched-capacitor filter applications. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | Single-supply only (+5V to +36V); 1.3Ω RON; no dual-supply support; 16-TSSOP package. | Requires redesign for ±15V systems; better suited for cost-sensitive consumer electronics than industrial test gear. | Select when only single-supply operation is needed and TSSOP footprint is acceptable. |
| TS5A3157DCKR | Lower voltage range (1.65V–5.5V); 0.75Ω RON; 6-pin SC70 package; no NC/NO asymmetry. | Restricted to low-voltage portable devices; lacks rail-to-rail capability and dual-channel independence of MAX4600CPE+. | Choose for battery-powered signal routing where size and ultra-low RON outweigh supply flexibility. |
Compared with ADG1419BRUZ and TS5A3157DCKR, MAX4600CPE+ uniquely supports both dual- and single-supply operation with asymmetric NC/NO topology, making it irreplaceable in legacy ±15V ATE and telecom infrastructure where supply architecture and fail-safe routing are non-negotiable.

FAQ
What is the operating temperature range for MAX4600CPE+?
The MAX4600CPE+ is rated for 0°C to +70°C ambient operation, as indicated by the "C" grade suffix in its part number. This commercial-grade temperature range suits indoor industrial control panels, benchtop test instruments, and telecom line cards not exposed to extreme thermal stress. The device is not qualified for extended industrial (–40°C to +85°C) operation - that specification applies to the MAX4600EPE variant.
Does MAX4600CPE+ support dual-supply operation?
Yes, MAX4600CPE+ fully supports dual-supply operation from ±4.5V to ±20V, enabling true rail-to-rail analog signal handling across ±10V ranges. When used in dual-supply mode, V+ connects to the positive rail, V− to the negative rail, and GND serves as the reference. This configuration is essential for applications like audio signal switching and precision instrumentation where bipolar signal integrity is mandatory.
How does the NC/NO configuration of MAX4600CPE+ differ from MAX4580 and MAX4590?
MAX4600CPE+ integrates one normally closed (NC) switch (Switch 1, active low) and one normally open (NO) switch (Switch 2, active high), whereas MAX4580CPE+ has two NC switches and MAX4590CPE+ has two NO switches. This hybrid configuration allows fail-safe default states - e.g., maintaining a diagnostic path via NC while enabling on-demand signal injection via NO - which is critical in safety-critical telecom and test system designs.
What is the maximum continuous current rating for MAX4600CPE+?
MAX4600CPE+ supports ±200mA continuous current per channel (COM_, NO_, or NC_ terminal), verified across the full 0°C to +70°C temperature range. This rating assumes proper PCB thermal design - including adequate copper pour on V+, V−, and GND pins - and is derated linearly above +70°C per the 10.53mW/°C dissipation limit specified for the 16-pin plastic DIP package.
Can MAX4600CPE+ be used with a 3.3V logic controller?
Yes, MAX4600CPE+ can interface with 3.3V logic controllers when VL is supplied with +3.3V, provided the input voltage thresholds remain within spec: VIN_L ≤ +0.8V and VIN_H ≥ +2.4V. Since 3.3V logic typically swings 0V/3.3V, the +2.4V high threshold is met, but margin is reduced. For guaranteed compatibility, use a level shifter or configure the controller to drive IN1/IN2 with 0V/+5V swing while keeping VL at +5V.
