Product details
Overview
MAX4605CSE+ from Maxim Integrated is a quad, single-pole single-throw (SPST), normally open (NO) CMOS analog switch with 5Ω maximum on-resistance, 0.5Ω maximum on-resistance match between channels, and rail-to-rail signal handling capability across ±4.5V to ±20V dual supplies or +4.5V to +36V single supply. It delivers low 2.5nA max off-leakage at +85°C and supports precision audio-signal routing in automatic test equipment.
For engineers reviewing the MAX4605CSE+ datasheet, MAX4605CSE+ pinout, MAX4605CSE+ application, or MAX4605CSE+ equivalent, key selection criteria include guaranteed RON flatness (0.5Ω max), TTL/CMOS-compatible logic thresholds (+0.8V/+2.4V), and SOIC-16 package compatibility with industrial temperature range (0°C to +70°C).
Technical Context
The MAX4605CSE+ implements four independent SPST NO switches using high-voltage CMOS process technology, enabling operation over wide analog signal ranges without distortion. Its matched RON and flat RON profile ensure consistent gain and minimal crosstalk in multi-channel signal routing.
All four digital control inputs accept TTL/CMOS logic levels regardless of supply configuration - verified at ±15V dual supply or +12V single supply - and interface directly to microcontroller GPIOs without level-shifting. The device integrates internal ESD protection (>2000V per Method 3015.7) and requires no external biasing for rail-to-rail analog operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 5Ω max - ensures minimal voltage drop and power loss in signal paths up to ±10V analog swing. |
| RON Match | 0.5Ω max - guarantees uniform channel gain in multi-path audio or instrumentation systems. |
| RON Flatness | 0.5Ω max over full signal range - maintains linearity and THD performance across rail-to-rail input voltages. |
| Off-Leakage Current | 2.5nA max at +85°C - preserves signal integrity in high-impedance sensor interfaces and precision measurement circuits. |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - supports legacy industrial, avionics, and test equipment power architectures. |
| Logic Thresholds | +0.8V low / +2.4V high - ensures reliable switching with standard 5V TTL and CMOS controllers without external translators. |
| Turn-On/Off Time | 120ns / 130ns typical (dual supply) - enables fast multiplexing in automated test and data acquisition systems. |
Pinout & Package
MAX4605CSE+ is housed in a 16-pin narrow SOIC (SO/DIP) package with 1.27mm pitch, rated for 0°C to +70°C operation. Pin 1 is located at the top-left corner adjacent to the index mark.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; active-high logic turns corresponding NO switch ON (COM ↔ NO). |
| 2, 7, 10, 15 | COM1–COM4 | Common analog terminals - bidirectional signal path connection points for each switch. |
| 3, 6, 11, 14 | NO1–NO4 | Normally open analog terminals - connect to COM only when respective IN is high. |
| 4 | V− | Negative analog supply rail; tied to GND for single-supply operation. |
| 5 | GND | Digital ground reference for logic inputs and VL supply return. |
| 12 | VL | Logic supply input - accepts 2.7V to 5.5V to set logic threshold levels independently of analog rails. |
| 13 | V+ | Positive analog supply rail - defines upper limit of rail-to-rail analog signal range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports continuous analog signals from V− to V+ without clipping or distortion - essential for audio and sensor front-ends. |
| Guaranteed RON match (0.5Ω max) | Enables precise channel balancing in differential or multi-path signal conditioning without calibration. |
| TTL/CMOS-compatible logic inputs | Eliminates need for level shifters when interfacing with 3.3V/5V microcontrollers or FPGAs in mixed-voltage systems. |
| ESD protection >2000V (HBM) | Reduces risk of field failure during handling or system integration without requiring external TVS devices. |
| Low charge injection (10pC typical) | Minimizes transient glitches in sample-and-hold or switched-capacitor circuits, preserving ADC accuracy. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1404BRUZ | 4-channel SPST NO, 4.7Ω RON, ±15V supply, but requires VL = VDD; no separate logic supply pin. | Higher bandwidth (170MHz –3dB) but higher charge injection (12pC) and no guaranteed RON match spec. | Prefer ADG1404BRUZ for RF-sensitive applications; choose MAX4605CSE+ when RON matching and independent VL are required. |
| TS5A3157DCKR | Single-channel SPDT, 0.75Ω RON, +1.65V to +5.5V supply only - not compatible with ±15V or >5.5V analog rails. | Optimized for portable low-voltage systems; lacks rail-to-rail support beyond 5V and fails absolute max ratings above +6V. | Select TS5A3157DCKR only for battery-powered 3.3V designs; MAX4605CSE+ remains necessary for industrial/high-voltage signal routing. |
Compared with ADG1404BRUZ and TS5A3157DCKR, the MAX4605CSE+ uniquely combines guaranteed RON matching, independent VL logic supply, and ±20V dual-rail operation - making it irreplaceable in precision test equipment and avionics where channel consistency and wide supply flexibility are mandatory.

FAQ
What is the operating temperature range for the MAX4605CSE+?
The MAX4605CSE+ is specified for operation from 0°C to +70°C. This commercial-grade temperature range is validated across all electrical parameters in the datasheet, including RON, leakage current, and switching times. For extended temperature operation down to -40°C or up to +85°C, the MAX4605ESE variant is available - the 'C' suffix in MAX4605CSE+ explicitly denotes the 0°C to +70°C grade.
Does the MAX4605CSE+ support rail-to-rail analog signals with single-supply operation?
Yes, the MAX4605CSE+ supports true rail-to-rail analog signal handling with single-supply operation from +4.5V to +36V. When V− is connected to GND, analog signals can swing continuously from GND to V+, maintaining low distortion and flat RON. This capability is confirmed in both the General Description and Electrical Characteristics tables for single-supply conditions (V+ = +12V, V− = 0).
Can the MAX4605CSE+ be used with a 3.3V logic supply?
Yes, the MAX4605CSE+ accepts 2.7V to 5.5V on the VL pin, making it fully compatible with 3.3V logic systems. The device's logic thresholds (+0.8V low, +2.4V high) remain valid across this VL range, ensuring reliable switching without external level translation - a key advantage over analog switches requiring VL = V+.
What is the maximum analog signal voltage the MAX4605CSE+ can handle?
The MAX4605CSE+ supports analog signals from V− to V+, with absolute maximum ratings of V+ to GND = −0.3V to +44V and V− to GND = +0.3V to −44V. Therefore, the maximum allowable analog signal span is 44V peak-to-peak - for example, ±20V dual supply yields a ±20V signal range, while +36V single supply allows 0V to +36V signals.
Is the MAX4605CSE+ pin-compatible with other devices in the MAX460x family?
Yes, the MAX4605CSE+ shares identical pinout and package (16-pin narrow SOIC) with MAX4604CSE+ and MAX4606CSE+. All three variants differ only in switch configuration (NO, NC, or mixed), allowing drop-in replacement in layouts designed for the same footprint - provided the logic polarity and channel mapping align with the target application.
