Product details
Overview
MAX4533EWP+T from Maxim Integrated is a quad SPDT analog switch with rail-to-rail signal handling, ±25V fault protection (power on) and ±40V fault protection (power off), 175Ω max on-resistance at ±15V supplies, and TTL/CMOS-compatible logic inputs-designed for high-reliability signal routing in test equipment and industrial data-acquisition systems where overvoltage transients are common.
For engineers reviewing the MAX4533EWP+T datasheet, MAX4533EWP+T pinout, MAX4533EWP+T application, or MAX4533EWP+T equivalent, this page delivers verified specifications, fault-protection behavior under dual/single supply operation, real-world timing performance (20ns typical fault response), and validated alternative options for redundant system design.
Technical Context
The MAX4533EWP+T implements a parallel N-channel/P-channel MOSFET architecture per channel, enabling rail-to-rail conduction while maintaining low on-resistance (125Ω typ). Its integrated voltage-sensing comparators monitor NO_/NC_ terminals continuously against V+ and V− rails to trigger fast fault isolation.
During overvoltage events, the switch disconnects COM_ from the faulty terminal within 20ns and clamps COM_ to the appropriate supply rail via dedicated clamp FETs (N2/P2), delivering up to ±10mA load current without transition glitches-ensuring deterministic output behavior even during transient faults.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | Dual ±4.5V to ±18V or single +9V to +36V - supports industrial bipolar and wide-range unipolar power architectures. |
| On-Resistance (max) | 175Ω at ±15V - ensures minimal signal attenuation and thermal drift in precision analog paths. |
| Fault Protection | ±25V with power on, ±40V with power off - protects downstream circuitry from accidental connection to external high-voltage sources. |
| Off-Leakage Current | 0.5nA at +25°C - preserves signal integrity in high-impedance sensor interfaces and battery-powered instruments. |
| Fault Response Time | 20ns typical - limits fault energy transfer and prevents latch-up in sensitive measurement front-ends. |
| Logic Compatibility | +0.8V / +2.4V thresholds - interoperates directly with TTL and CMOS controllers without level-shifting across full temperature range. |
| Operating Temp | -40°C to +85°C - qualified for extended industrial and avionics environments without derating. |
Pinout & Package
MAX4533EWP+T is housed in a 20-pin Wide SO (SOIC-W) package, 7.6mm × 12.8mm body, 1.27mm pitch, with exposed pad for thermal enhancement. Pin 15 is NC (not internally connected); GND (pin 6) and V− (pin 5) are separate for analog/digital ground separation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (pins 1,10,11,20) | Digital control inputs | TTL/CMOS-compatible logic signals that select NO or NC path per channel; no power sequencing required. |
| NO1–NO4 (pins 2,9,12,19) | Normally open analog inputs | Fault-protected terminals accepting signals up to ±40V (power off); bidirectional when within supply rails. |
| COM1–COM4 (pins 3,8,13,18) | Analog common outputs | Rail-to-rail output node; clamped to V+ or V− during fault; delivers ±10mA load current during clamp event. |
| NC1–NC4 (pins 4,7,14,17) | Normally closed analog inputs | Identical fault protection and bidirectional operation as NO pins; complementary path to COM. |
| V+ (pin 16) | Positive supply input | Powers analog switches and internal logic; sets logic threshold high level; supports up to +36V in single-supply mode. |
| V− (pin 5) | Negative supply input | Required for dual-supply operation; enables true bipolar signal handling and reduces RON via enhanced gate drive. |
| GND (pin 6) | Digital ground reference | Reference for logic inputs and internal translators; isolated from analog signal paths to prevent noise coupling. |
| NC (pin 15) | No connection | Unbonded die pad; must remain floating-no PCB trace or solder mask opening required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal conduction | Enables full dynamic range utilization in ±15V or +12V systems without signal clipping or distortion. |
| Automatic output clamping during fault | Prevents undefined output states by forcing COM_ to V+ or V− within 20ns-eliminates need for external clamps. |
| All-switches-off state at power loss | Guarantees safe open-circuit condition during brownout or hot-swap events-critical for system-level safety compliance. |
| Matched on-resistance (≤10Ω) | Ensures consistent gain and phase response across all four channels in multiplexed instrumentation applications. |
| No power-supply sequencing requirement | Allows independent ramp-up of V+, V−, and logic supplies-simplifies power management in multi-rail systems. |
| Break-before-make switching | Prevents momentary shorting between NO and NC paths-essential for avoiding signal corruption in high-precision muxes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4532EWP+T | Triple SPDT configuration (3 channels vs. 4); identical fault protection, RON, and timing specs. | Suitable when only three signal paths are needed-reduces channel count but retains same reliability profile. | Select MAX4532EWP+T for cost-sensitive designs with lower channel density requirements. |
| ADG1434YRUZ | 4-channel SPDT with ±15V supplies only; 4.7Ω typical RON; no ±40V power-off fault rating. | Better RON for low-distortion audio routing, but lacks MAX4533EWP+T's extended fault margin for industrial field wiring. | Choose ADG1434YRUZ only when ultra-low on-resistance is critical and fault exposure is limited to ±15V. |
Compared with MAX4532EWP+T and ADG1434YRUZ, the MAX4533EWP+T uniquely balances quad-channel count, ±40V power-off fault tolerance, and industrial temperature range-making it the sole option for high-availability test and control systems requiring guaranteed open-circuit safety during total power loss.

FAQ
What is the maximum fault voltage the MAX4533EWP+T can withstand with power applied?
The MAX4533EWP+T withstands ±25V fault voltages on NO_/NC_ terminals when power is applied (V+ and V− active). This rating applies across its full operating temperature range (-40°C to +85°C) and is validated per Absolute Maximum Ratings table in the official datasheet. Exceeding ±25V with supplies active risks permanent damage.
Does the MAX4533EWP+T require power-supply sequencing during startup or shutdown?
No, the MAX4533EWP+T does not require power-supply sequencing. Its internal logic-level translators and fault-protection circuitry operate correctly regardless of the order in which V+, V−, and digital logic supplies ramp up or down-simplifying power management in complex multi-rail systems.
How does the MAX4533EWP+T behave during a fault condition on the NO_ or NC_ terminal?
When a fault occurs (e.g., NO_ exceeds V+ by >150mV), the MAX4533EWP+T immediately disconnects the affected channel and clamps COM_ to the appropriate supply rail (V+ for positive faults, V− for negative faults) within 20ns. During clamping, it sustains up to ±10mA load current without glitching-ensuring predictable downstream behavior.
Can the MAX4533EWP+T operate from a single +12V supply?
Yes, the MAX4533EWP+T operates from a single +12V supply with V− tied to GND. In this configuration, its fault-free analog signal range is 0V to +12V, on-resistance is 260Ω max, and logic thresholds remain compatible with standard 0V/+5V or 0V/+12V control signals-verified in the Single-Supply Electrical Characteristics table.
What is the on-resistance matching specification for the MAX4533EWP+T?
The MAX4533EWP+T guarantees ≤10Ω on-resistance matching (∆RON) between any two channels at ±15V supplies and +25°C. This tight matching ensures uniform gain and phase response across all four SPDT switches-critical for precision multiplexing in data-acquisition and calibration-critical applications.
