Product details
Overview
MAX4665CPE+ from Maxim Integrated is a quad single-pole single-throw (SPST) analog switch with normally open (NO) configuration, designed for rail-to-rail signal routing in precision analog systems. It delivers 5Ω maximum on-resistance, 0.5Ω maximum on-resistance match between channels, and 5nA maximum off-leakage current at +85°C - enabling low-distortion audio-signal routing and reed-relay replacement in test equipment.
For engineers reviewing the MAX4665CPE+ datasheet, MAX4665CPE+ pinout, MAX4665CPE+ application, or MAX4665CPE+ equivalent, key selection criteria include guaranteed RON flatness (0.5Ω max over ±10V signal range), TTL/CMOS-compatible logic thresholds (+0.8V / +2.4V), and dual-supply operation (±4.5V to ±20V) or single-supply operation (+4.5V to +36V).
Technical Context
The MAX4665CPE+ implements CMOS-based SPST switching architecture with four independent NO switches, each featuring matched and flat on-resistance across its full analog signal range. Its control logic accepts standard TTL/CMOS levels regardless of supply configuration - supporting interoperability with +12V single-supply or ±15V dual-supply systems.
All switches handle rail-to-rail analog signals up to ±10V with guaranteed break-before-make timing only in the MAX4666 variant; the MAX4665CPE+ does not implement break-before-make. ESD protection exceeds 2kV per Method 3015.7, and leakage performance is fully specified from -40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 5Ω max - ensures minimal voltage drop and signal attenuation in low-level analog paths |
| RON Match | 0.5Ω max between channels - critical for matched gain/phase in multi-channel signal routing |
| RON Flatness | 0.5Ω max over ±10V signal range - preserves linearity in audio and instrumentation applications |
| Off-Leakage Current | 5nA max at +85°C - enables high-impedance sensor multiplexing without DC error accumulation |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, avionics, and legacy ±15V systems |
| Logic Thresholds | +0.8V low / +2.4V high - ensures reliable TTL/CMOS compatibility without level-shifting circuitry |
| Turn-On/Off Time | 130ns / 90ns typical (dual supply) - suitable for moderate-speed multiplexing (≤5MHz) |
Pinout & Package
MAX4665CPE+ uses a 16-pin plastic DIP (dual in-line package) with 0.3-inch body width and through-hole mounting. Pin spacing is 0.1 inch, compatible with standard PCB layouts and socketing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs - active-high logic turns corresponding NO switch ON |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - connect to signal source or load in SPST topology |
| 3, 6, 11, 14 | NO1–NO4 | Normally open analog outputs - conduct only when respective INx = logic high |
| 4 | V− | Negative analog supply - tie to GND for single-supply operation |
| 5 | GND | Digital ground reference - must be connected even in dual-supply mode |
| 12 | VL | Logic supply input - accepts +2.7V to +7V, independent of analog supplies |
| 13 | V+ | Positive analog supply - sets upper rail for rail-to-rail analog signal handling |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports continuous analog signals from V− to V+, enabling full dynamic range utilization in ±15V or +12V systems |
| Guaranteed RON match and flatness | 0.5Ω max channel-to-channel mismatch and 0.5Ω max variation across ±10V - essential for precision multiplexing |
| TTL/CMOS-compatible logic interface | +0.8V / +2.4V thresholds ensure direct connection to microcontrollers and FPGAs without external level shifters |
| Low off-leakage current | 5nA max at +85°C - prevents signal corruption in high-Z sensor front-ends and sample-hold circuits |
| ESD robustness | >2kV per Method 3015.7 - reduces susceptibility to handling damage in manufacturing and field service |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1414BRUZ | 4-channel SPST, 1.8Ω RON, ±15V/0–12V supply, but requires separate VDD/VSS pins and no VL pin | Better RON and lower charge injection, but lacks independent logic supply (VL) for mixed-voltage control | Prefer ADG1414BRUZ when ultra-low RON and charge injection are critical, and logic supply can be derived from analog rails |
| TS5A3154DCUR | Single 1:1 SPST, 0.75Ω RON, +1.65V to +5.5V supply only, no dual-supply support | Lower voltage, higher speed (42ns tON), but limited to 5.5V max and unsuitable for ±15V or >12V systems | Choose TS5A3154DCUR for battery-powered, low-voltage signal routing where dual-supply capability is unnecessary |
Compared with ADG1414BRUZ and TS5A3154DCUR, the MAX4665CPE+ uniquely supports independent logic supply (VL), wide dual/single supply ranges, and guaranteed RON flatness - making it optimal for industrial and avionics designs requiring robust, rail-to-rail analog switching with flexible control interfacing.

FAQ
What is the maximum supply voltage rating for MAX4665CPE+?
The MAX4665CPE+ supports absolute maximum analog supply ratings of V+ to GND = −0.3V to +44V and V− to GND = +0.3V to −44V. For reliable operation, use within the recommended ranges: +4.5V to +36V single supply or ±4.5V to ±20V dual supply. Exceeding these limits risks permanent damage due to internal diode clamping.
Does MAX4665CPE+ support break-before-make switching?
No, the MAX4665CPE+ does not support break-before-make switching. That feature is exclusive to the MAX4666 variant (which integrates two NC and two NO switches with guaranteed timing). The MAX4665CPE+ contains four independent normally open (NO) switches with standard make-before-break behavior during logic transitions.
Can MAX4665CPE+ operate with a single +5V supply?
Yes, the MAX4665CPE+ operates with a single +5V supply, but only if V+ = +5V and V− = GND. However, note that RON increases significantly below +12V - typical RON is 5.5Ω at +5V (vs. 5Ω max at +12V). Also, VL must be supplied separately (2.7V–7V), and logic thresholds remain fixed at +0.8V/+2.4V.
What is the purpose of the VL pin on MAX4665CPE+?
The VL pin on MAX4665CPE+ provides an independent logic supply input (2.7V to 7V), decoupling digital control voltage from analog supply rails. This allows interfacing with 3.3V or 5V microcontrollers while operating analog sections at ±15V or +24V - eliminating level-shifter circuitry and improving noise immunity in mixed-voltage systems.
Is MAX4665CPE+ pin-compatible with other devices in the MAX4664/MAX4665/MAX4666 family?
Yes, all variants - MAX4664CPE+, MAX4665CPE+, and MAX4666CPE+ - share identical 16-pin DIP pinouts and package dimensions. Functionally, only the switch configuration differs: MAX4664 is four NC, MAX4665 is four NO, and MAX4666 is two NC + two NO. PCB layout and footprint are fully interchangeable across the family.
