Product details
Overview
MAX4513EPE from Maxim Integrated is a quad SPST analog switch with two normally closed (NC) and two normally open (NO) channels, fault-protected up to ±36V with ±15V supplies or ±40V with power off, 175Ω max on-resistance at ±15V, rail-to-rail signal handling, and TTL/CMOS-compatible logic inputs - used in industrial process-control systems for robust signal routing under overvoltage transients.
For engineers reviewing the MAX4513EPE datasheet, MAX4513EPE pinout, MAX4513EPE application, or MAX4513EPE equivalent, key selection criteria include fault protection voltage range, on-resistance matching (≤10Ω), break-before-make timing (50–100ns), dual/supply operation (±4.5V to ±18V or +9V to +36V), and compatibility with legacy DG201/DG202/DG213 layouts.
Technical Context
The MAX4513EPE implements parallel N- and P-channel FET architecture per channel to achieve low on-resistance and true rail-to-rail conduction. Its dual comparator-based fault detection monitors NO_/NC_ pins continuously, disabling signal paths and enabling booster FETs (capable of ±10mA) to clamp COM_ to V+ or V− during overvoltage events.
Unlike traditional triple-FET fault-protected switches, it avoids rail-proximal on-resistance degradation and delivers glitch-free clamping with no transition artifacts. Break-before-make timing (50–100ns) is explicitly specified only for the MAX4513 variant, ensuring channel isolation during state changes in redundant signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (max) | 175Ω at ±15V - ensures minimal signal attenuation and thermal drift in precision analog routing |
| On-resistance match | ≤10Ω between channels - enables matched gain/phase in multi-channel instrumentation front-ends |
| Fault protection range | ±36V with ±15V supplies; ±40V with power off - protects against transient surges in avionics and industrial I/O |
| Supply range | ±4.5V to ±18V dual or +9V to +36V single - supports wide-input industrial power rails without external regulation |
| Logic thresholds | +0.8V low / +2.4V high - guarantees interoperability with both TTL and CMOS drivers at +12V or ±15V supply |
| Turn-off time (tOFF) | 500–750ns at ±15V - enables reliable switching in data acquisition sampling windows ≥1µs |
| Break-before-make delay | 50–100ns (MAX4513 only) - prevents momentary shorting in hot-swap or backup-system crosspoint routing |
Pinout & Package
MAX4513EPE uses a 16-pin plastic DIP package (0.300" width), rated for -40°C to +85°C operation. Pin assignments are identical to industry-standard DG201/DG202/DG213, enabling drop-in replacement in legacy designs where only NO_/NC_ pins require fault protection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; drive internal logic translators to switch state and fault response |
| 2, 7, 10, 15 | COM1–COM4 | Common analog terminals; not fault-protected - must remain within V+/V− rails |
| 3, 6, 11, 14 | NC1, NC2, NO3, NO4 | Fault-protected analog terminals: NC1/NC2 normally closed; NO3/NO4 normally open |
| 4 | V− | Negative supply input; connect to GND for single-supply operation (+9V to +36V) |
| 13 | V+ | Positive supply and logic reference; internally tied to substrate; sets logic thresholds |
| 5 | GND | Digital ground reference; hosts ESD diodes to V+/V− but no analog signal reference |
| 12 | N.C. | No internal connection - must be left unconnected |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Signals from V− to V+ pass unattenuated in both directions when within supply rails |
| Fault-protected NO_/NC_ pins | Withstand ±36V faults with power applied; ±40V with power off - eliminates need for external TVS |
| Output clamping during fault | COM_ actively driven to V+ or V− by booster FETs (±10mA capability) - ensures defined output state |
| No supply sequencing required | V+ and V− may be powered in any order - simplifies power-up sequencing in multi-rail systems |
| Pin-compatible replacement | Direct layout swap for DG201/DG202/DG213 - reduces redesign effort while adding fault resilience |
Applications

IC Role / Device Role / Timing Role: Dual-NC/dual-NO configuration allows simultaneous monitoring and failover routing with deterministic fault response. Use Value: Maintains signal integrity during ±40V power-off faults - critical for DO-160 Section 22 lightning-induced transient compliance. |
Use Scenario: Crosspoint switching between primary and backup control processors in railway signaling or nuclear plant safety systems. IC Role / Device Role / Timing Role: Two NC and two NO switches implement hardware-enforced mutual exclusion with no software dependency.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4513CPE | Same functionality, but rated for 0°C to +70°C industrial temperature range | Suitable for non-extended-temperature commercial equipment; lower cost for benign environments | Select MAX4513CPE when ambient operating temperature stays within 0°C–70°C and extended reliability testing is not required |
| ADG413BRZ | Quad SPST, ±15V-rated, but lacks fault protection and rail-to-rail clamping; 35Ω typical RON | Used in precision low-RON applications where fault transients are absent or externally suppressed | Choose ADG413BRZ only if system-level overvoltage protection is already implemented upstream |
Compared with MAX4513CPE, the MAX4513EPE adds -40°C to +85°C operation for harsh environments; compared with ADG413BRZ, it provides integrated ±36V fault tolerance and active COM_ clamping - eliminating external protection circuitry and reducing BOM count in safety-critical routing.

FAQ
What is the maximum fault voltage the MAX4513EPE can withstand with power applied?
The MAX4513EPE withstands ±36V faults on its NO_ and NC_ pins when powered with ±15V supplies. With other supply voltages, the absolute limit remains ±36V referenced to GND, as specified in the Absolute Maximum Ratings table. Exceeding this risks permanent damage, even momentarily.
Does the MAX4513EPE support single-supply operation, and what is the valid voltage range?
Yes, the MAX4513EPE supports single-supply operation with V− tied to GND and V+ ranging from +9V to +36V. In this configuration, the fault-protected analog signal range remains ±36V relative to GND, and logic thresholds remain compatible with standard TTL/CMOS drivers.
How does the MAX4513EPE differ from the MAX4511EPE and MAX4512EPE in channel configuration?
The MAX4513EPE integrates two normally closed (NC1, NC2) and two normally open (NO3, NO4) SPST switches in one package. In contrast, MAX4511EPE contains four NC switches, and MAX4512EPE contains four NO switches - making MAX4513EPE uniquely suited for applications requiring mixed switching polarity.
Is the COM_ pin fault-protected on the MAX4513EPE?
No, the COM_ pins on the MAX4513EPE are not fault-protected. They must remain within the V+ to V− supply rails at all times. Exceeding these limits forward-biases internal ESD diodes, risking damage. Only NO_ and NC_ pins feature ±36V fault tolerance.
What is the purpose of the break-before-make timing specification for the MAX4513EPE?
The break-before-make delay (50–100ns) ensures that one switch opens before another closes in the MAX4513EPE's dual-NC/dual-NO topology. This prevents momentary shorting between signal paths - essential in redundant systems, crosspoint routing, and hot-swap interfaces where signal contention must be avoided.
