Product details
Overview
The MAX4580EWE from Maxim Integrated is a dual SPST CMOS analog switch with two normally closed (NC) channels, designed for rail-to-rail signal routing in precision analog systems. It delivers 1.25Ω max on-resistance, 0.25Ω max channel-to-channel RON match, and 2.5nA max off-leakage at +85°C, enabling low-distortion switching in automatic test equipment and communication interfaces.
For engineers reviewing the MAX4580EWE datasheet, MAX4580EWE pinout, MAX4580EWE application, or MAX4580EWE equivalent, key selection criteria include its -40°C to +85°C industrial temperature range, 16-pin Wide SO package, dual-supply (±4.5V to ±20V) or single-supply (+4.5V to +36V) operation, and TTL/CMOS-compatible logic thresholds.
Technical Context
The MAX4580EWE implements a CMOS-based dual SPST architecture with independent NC-type switches, each featuring matched on-resistance and flat RON (0.3Ω max) over the full ±10V signal range. Its internal protection diodes clamp signals exceeding V+ or V−, and it supports logic-level translation via separate VL pin referenced to +5V.
Operation is defined across two supply configurations: ±4.5V to ±20V dual supplies or +4.5V to +36V single supply, with guaranteed TTL/CMOS compatibility at +12V single-supply or ±15V dual-supply conditions. Input logic thresholds are fixed at +0.8V (low) and +2.4V (high), independent of supply voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 1.25Ω max - ensures minimal signal attenuation and voltage drop in precision analog paths |
| RON Match | 0.25Ω max - enables accurate differential or ratiometric measurements between channels |
| RON Flatness | 0.3Ω max - maintains consistent gain and linearity across ±10V input range |
| Off-Leakage Current | 2.5nA max at +85°C - preserves high-impedance node integrity in sensor front-ends |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports wide industrial and test-equipment power architectures |
| Logic Thresholds | +0.8V low / +2.4V high - guarantees reliable interface with standard TTL/CMOS controllers at +12V supply |
| Turn-On/Off Time | 150ns / 200ns typical - suitable for moderate-speed multiplexing up to ~1MHz |
Pinout & Package
MAX4580EWE is housed in a 16-pin Wide SO (SOIC-W) package, 7.6mm × 10.3mm body, 1.27mm lead pitch, with gull-wing leads and exposed pad not present. Pin 1 is top-left corner, marked by beveled edge or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | No-connect (N.C.) | Not internally connected; tie to GND or low-impedance point to improve isolation |
| 2, 7 | COM1, COM2 | Analog common terminals - bidirectional signal path entry points for each NC switch |
| 4 | V− | Negative analog supply - connect to GND for single-supply operation |
| 5 | GND | Ground reference for analog and logic sections - must be low-impedance return path |
| 9, 16 | NC1, NC2 | Normally closed analog terminals - conduct to COM when IN = low |
| 11, 14 | COM1, COM2 | Duplicate COM pins - electrically identical to pins 2 and 7; use for layout routing flexibility |
| 12 | VL | Logic supply input - decoupled +5V reference for control logic, independent of analog supplies |
| 13 | V+ | Positive analog supply - sets upper rail for rail-to-rail signal handling |
| 1, 3, 6, 8, 10, 15 | N.C. | Unused pins - no internal connection; avoid floating to prevent EMI coupling |
| IN1, IN2 | Control Inputs | Active-low logic inputs - drive low to close NC path (COM ↔ NC); high to open |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for full-scale sensor or DAC output switching |
| Guaranteed RON match | 0.25Ω max mismatch between channels - enables precise channel balancing in instrumentation amplifiers |
| ESD protection | >2kV per Method 3015.7 - enhances robustness in handling-sensitive lab and field environments |
| Low charge injection | 40pC typical - minimizes transient glitches in sample-and-hold or ADC input multiplexing |
| Off-isolation | -53dB typical - suppresses crosstalk between active and inactive channels in dense signal routing |
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 |
|---|---|---|---|
| MAX4590EWE | Two NO (normally open) switches instead of NC; identical RON, leakage, and supply specs | Requires active logic high to enable conduction - suited for default-open fail-safe configurations | Select MAX4590EWE when system requires open-circuit default state on power-up or logic fault |
| ADG1419BRUZ | 1.3Ω RON, ±15V dual-supply only, no VL pin, 16-TSSOP package, 1.5nA leakage at +85°C | Lacks single-supply support and logic-level translation; tighter leakage but narrower supply flexibility | Choose ADG1419BRUZ only if dual-supply-only operation is acceptable and lower leakage is critical |
Compared with MAX4580EWE, MAX4590EWE provides complementary logic behavior (NO vs NC) with identical analog performance, while ADG1419BRUZ trades supply flexibility and logic interface for marginally lower leakage in dual-supply-only systems.

FAQ
What is the operating temperature range for the MAX4580EWE?
The MAX4580EWE is rated for -40°C to +85°C, qualifying it for industrial and extended-temperature applications. This range is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the datasheet. The 'E' suffix explicitly denotes the extended temperature grade, distinct from the 'C' grade (0°C to +70°C). All electrical specifications in the datasheet are guaranteed across this full -40°C to +85°C range unless otherwise noted.
Does the MAX4580EWE support single-supply operation?
Yes, the MAX4580EWE supports single-supply operation from +4.5V to +36V, with V− connected to GND. The Electrical Characteristics table explicitly lists "Single Supply" parameters (V+ = +12V, V− = 0), and the General Description confirms compatibility with +4.5V to +36V single supplies. Logic inputs remain TTL/CMOS-compatible under this configuration due to fixed +0.8V/+2.4V thresholds.
What is the function of the VL pin on the MAX4580EWE?
Pin 12 (VL) is the logic supply input, requiring a +5V decoupled supply to power the internal digital control circuitry. It operates independently of the analog supplies (V+, V−), enabling level-shifting between logic and analog domains. The datasheet specifies VL = +5V in all test conditions, and deviation from this voltage may affect logic threshold stability and switching performance.
How does the MAX4580EWE differ from the MAX4590EWE?
The MAX4580EWE contains two normally closed (NC) switches, while the MAX4590EWE contains two normally open (NO) switches. Their analog specifications (RON, leakage, bandwidth, supply ranges) are identical. The functional difference lies solely in default state: MAX4580EWE conducts when IN = low, whereas MAX4590EWE conducts when IN = high. Pinout and package are identical.
Is the MAX4580EWE pin-compatible with other packages in the same family?
Yes, the MAX4580EWE (16-pin Wide SO) shares identical pinout and functionality with the MAX4580EAE (16-pin SSOP) and MAX4580EPE (16-pin Plastic DIP). The Pin Configurations diagram confirms identical terminal assignments across all three packages. This allows direct PCB footprint substitution between SO, SSOP, and DIP variants without circuit modification.
