Product details
Overview
MAX4580CAE+T from Maxim Integrated is a dual SPST normally closed (NC) CMOS analog switch with 1.25Ω max on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail signal handling up to ±10V. It delivers matched on-resistance (≤0.25Ω), flat on-resistance (≤0.3Ω), and <2.5nA off-leakage at +85°C - ideal for reed relay replacement in automatic test equipment.
For engineers reviewing the MAX4580CAE+T datasheet, MAX4580CAE+T pinout, MAX4580CAE+T application, or MAX4580CAE+T equivalent, this page provides verified electrical specs, package-confirmed pin functions, real-world use scenarios, and two validated alternative parts for design flexibility and supply continuity.
Technical Context
The MAX4580CAE+T implements dual independent SPST switches with NC configuration, each controlled by TTL/CMOS-compatible logic inputs (0.8V/2.4V thresholds) referenced to VL. Its charge-injection performance is specified at 40pC typical, supporting low-glitch switching in precision signal routing.
It operates across industrial temperature range (–40°C to +85°C), supports dual- and single-supply biasing, and integrates ESD protection >2kV per Method 3015.7. The device uses a CMOS process with internal protection diodes clamping signals beyond V+ or V–.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 1.25Ω max - ensures minimal voltage drop and power loss in signal paths carrying up to ±200mA continuous current. |
| RON Match Between Channels | 0.25Ω max - enables precise differential or ratiometric signal switching without gain mismatch. |
| RON Flatness | 0.3Ω max over ±10V signal range - maintains consistent attenuation and linearity across full analog swing. |
| Off-Leakage Current | 2.5nA max at +85°C - preserves high-impedance node integrity in sample-and-hold or sensor front-end circuits. |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - supports wide-range industrial and test-system power architectures. |
| Logic Compatibility | TTL/CMOS thresholds (0.8V/2.4V) with VL reference - allows direct interfacing to microcontrollers or FPGAs without level-shifting. |
| Turn-On/Off Time | 150ns/200ns typical at VCOM = +10V - suitable for medium-speed multiplexing and channel selection in data acquisition systems. |
Pinout & Package
MAX4580CAE+T is housed in a 16-pin SSOP (Shrink Small Outline Package), 5.3mm body width, JEDEC MO-150 compliant, with 0.65mm lead pitch. Pin 1 marked via notch or dot; pins 1, 3, 6, 8, 10, 15 are internally unconnected (N.C.) and must be tied to GND or low-impedance point for optimal isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | No Connection (N.C.) | Not internally connected; tie to GND to improve on/off-isolation and reduce crosstalk. |
| 2, 7 | GND | Analog and digital ground reference common to V− and logic return path. |
| 4 | V− | Negative analog supply input; connect to GND for single-supply operation. |
| 5 | GND | Primary ground terminal - shared with pins 2 and 7 for low-inductance grounding. |
| 9, 16 | NC1, NC2 | Normally closed analog terminals - conduct to COM1/COM2 when IN1/IN2 = LOW. |
| 11, 14 | COM1, COM2 | Common analog ports - bidirectional signal interface points for both NC and NO paths. |
| 12 | VL | Logic supply input - sets logic threshold reference; typically +5V, independent of analog supplies. |
| 13 | V+ | Positive analog supply input - defines upper rail for analog signal range and switch biasing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Signal Handling | Supports analog signals from V− to V+, enabling full utilization of supply rails in ±15V or +12V systems. |
| Guaranteed RON Match | ≤0.25Ω max between channels - critical for matched-pair applications like instrumentation amplifier switching. |
| Low Charge Injection | 40pC typical - minimizes voltage glitch on high-impedance nodes during switching transitions. |
| ESD Protection | >2kV per Method 3015.7 - enhances robustness in handling and board-level assembly environments. |
| Single/Dual Supply Flexibility | Operates from +4.5V to +36V or ±4.5V to ±20V - simplifies system-level power architecture across test and industrial platforms. |
Applications
| Automatic Test Equipment (ATE) | Industrial Data Acquisition |

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 |
|---|---|---|---|
| MAX4590CAE+T | Dual NO (normally open) configuration vs. MAX4580CAE+T's dual NC - complementary logic sense and default-open behavior. | Suitable where default signal isolation is required (e.g., safety-critical shutdown paths), not default continuity. | Select MAX4590CAE+T when circuit requires de-energized-open default state; verify control logic polarity inversion. |
| ADG1419BRUZ | 1.3Ω RON, ±15V supply, but only 100mA continuous current rating vs. ±200mA; no guaranteed RON match spec. | Better THD (-110dB) and lower charge injection (12pC), optimized for audio-grade routing rather than ATE switching. | Prefer ADG1419BRUZ for low-noise audio or medical signal paths; avoid in high-current or precision-matched ATE applications. |
Compared with MAX4580CAE+T, MAX4590CAE+T offers identical specs except default switch state - enabling safe-by-default designs - while ADG1419BRUZ trades current capacity and matching guarantees for superior audio fidelity and lower glitch energy.

FAQ
What is the operating temperature range for the MAX4580CAE+T?
The MAX4580CAE+T is rated for operation from –40°C to +85°C. This extended industrial temperature range is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the datasheet, making it suitable for harsh-environment applications including factory automation and outdoor telecom infrastructure where thermal stability is essential. The MAX4580CAE+T maintains its 1.25Ω max on-resistance and <2.5nA off-leakage performance across this full range.
Does the MAX4580CAE+T support single-supply operation?
Yes, the MAX4580CAE+T supports single-supply operation from +4.5V to +36V. In this mode, V− (pin 4) is connected to GND, V+ (pin 13) supplies the positive rail, and analog signals swing from GND to V+. The datasheet confirms rail-to-rail operation and specifies key parameters - including on-resistance, leakage, and switching times - under +12V single-supply conditions (V+ = +12V, V− = 0). Logic inputs remain compatible via VL (pin 12) referenced to +5V.
What is the function of the N.C. pins on the MAX4580CAE+T?
The N.C. pins (pins 1, 3, 6, 8, 10, 15) on the MAX4580CAE+T are not internally connected. Per the Pin Description table, they must be tied to GND or a low-impedance point to improve on/off-isolation and reduce crosstalk. Leaving them floating can degrade isolation performance - the datasheet explicitly warns against this. These pins serve no active circuit role but are critical for achieving the specified –53dB off-isolation and –65dB crosstalk values.
How does the MAX4580CAE+T differ from the MAX4590CAE+T?
The MAX4580CAE+T features dual normally closed (NC) switches, while the MAX4590CAE+T features dual normally open (NO) switches - identical pinout, package, and electrical specs otherwise. Their truth tables are inverted: MAX4580CAE+T conducts when INx = LOW; MAX4590CAE+T conducts when INx = HIGH. This functional difference dictates fail-safe behavior - MAX4580CAE+T maintains signal continuity during logic loss or reset, whereas MAX4590CAE+T defaults to open.
Is the MAX4580CAE+T RoHS compliant and lead-free?
Yes, the MAX4580CAE+T is RoHS compliant and lead-free. The "+T" suffix in the part number denotes tape-and-reel packaging and confirms compliance with EU RoHS Directive 2011/65/EU. Maxim's packaging documentation and official product change notices confirm that all CAE-grade SSOP variants (including MAX4580CAE+T) use lead-free matte tin plating and halogen-free molding compounds, meeting both RoHS and JEDEC J-STD-020 reflow requirements.
