Analog Devices Inc./Maxim Integrated MAX313FESE+

Overview

MAX313FESE+ from Maxim Integrated is a quad, single-pole/single-throw (SPST), normally open (NO), fault-protected analog switch IC. It operates with ±4.5V to ±20V dual supplies or +9V to +36V single supply, delivers 10Ω max on-resistance at ±15V, supports rail-to-rail signal handling up to ±36V (power on) or ±40V (power off), and features 600ns typical fault response time. It is used in high-reliability signal routing for test equipment and industrial control systems where overvoltage transients are common.

For engineers reviewing the MAX313FESE+ datasheet, MAX313FESE+ pinout, MAX313FESE+ application, or MAX313FESE+ equivalent, key selection criteria include fault protection voltage range, on-resistance matching across channels, TTL/CMOS logic compatibility at ±15V or +12V, and SO-16 package compatibility with legacy DG411/DG412 footprints.

Technical Context

The MAX313FESE+ implements dual-FET (N+P channel) parallel switching per channel to achieve low R_ON and true bidirectional rail-to-rail conduction. Its internal fault-protection architecture uses independent high- and low-voltage comparators on each COM_/NO_ terminal to detect overvoltage excursions beyond V+ or below V−, forcing immediate high-impedance isolation.

Unlike standard analog switches, it maintains full fault protection with power removed (±40V), turns all switches OFF when V+ is unpowered (even if V− is active), and provides matched R_ON ≤ 0.5Ω (max) between channels at +25°C - critical for precision multiplexing in data acquisition systems.

Key Specifications

Pinout & Package

MAX313FESE+ is housed in a 16-pin SOIC (SO) package with 1.27mm pitch, JEDEC MS-012AC compliant, and rated for -40°C to +85°C operation. The package includes integrated 0.1µF bypass capacitors recommended on V+ and GND pins.

FAQ

What is the maximum fault voltage the MAX313FESE+ can withstand with power removed?

The MAX313FESE+ sustains ±40V fault voltage on COM_, NO_, or NC_ terminals with all supplies disconnected. This is verified per Absolute Maximum Ratings and enables safe handling during maintenance or hot-swap scenarios where power may be absent but signal lines remain energized. The device enters high-impedance state instantly, limiting leakage to <10µA under ±40V fault conditions - a key differentiator versus non-fault-protected alternatives.

Does the MAX313FESE+ require power-supply sequencing during startup?

No, the MAX313FESE+ does not require power-supply sequencing. It operates safely whether V+ ramps before V−, after V−, or simultaneously. This is enabled by its internal logic-level translators and comparator architecture, which remain functional across the full valid supply range. The MAX313FESE+ also turns all switches OFF if V+ is unpowered - even when V− is active - eliminating risk of signal leakage during asymmetric power-up.

Can the MAX313FESE+ be used with a single +12V supply?

Yes, the MAX313FESE+ supports single +12V operation with V− tied to GND. In this configuration, it maintains rail-to-rail signal handling from 0V to +12V, 30Ω max R_ON, ±36V fault protection (power on), and TTL/CMOS logic compatibility. All electrical characteristics - including 600ns fault response and -55dB off-isolation - are validated per the +12V single-supply specification table in the datasheet.

How does the MAX313FESE+ compare to the MAX313 (non-F version)?

The MAX313FESE+ adds comprehensive fault protection - ±36V with power on, ±40V with power off - while retaining identical pinout, R_ON, timing, and logic compatibility with the legacy MAX313. Unlike the MAX313, the MAX313FESE+ integrates dual-FET switch topology and real-time fault comparators, enabling automatic high-impedance isolation during overvoltage events without external components. It is not a drop-in replacement for MAX313 in circuits relying on undefined fault behavior.

Is the MAX313FESE+ compatible with DG412 pinout and functionality?

Yes, the MAX313FESE+ is pin-compatible with DG412 and other industry-standard quad SPST NO switches (DG411/DG413). Its INx, COMx, and NOx pin assignments match exactly, and it accepts the same ±15V or +12V supplies and TTL/CMOS logic levels. However, unlike DG412, the MAX313FESE+ provides full fault protection on all analog terminals and requires no external protection circuitry - enabling direct PCB-level replacement in existing designs.
