Analog Devices Inc./Maxim Integrated DG413FEUE+T

Overview

DG413FEUE+T from Maxim Integrated is a quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels, fault-protected to ±36V with power on and ±40V with power off, 35Ω max on-resistance at ±15V, rail-to-rail signal handling, and TTL/CMOS-compatible logic inputs - used in redundant signal routing for industrial control systems.

For engineers reviewing the DG413FEUE+T datasheet, DG413FEUE+T pinout, DG413FEUE+T application, or DG413FEUE+T equivalent, key selection criteria include fault protection voltage range, on-resistance matching (≤1.5Ω), break-before-make timing (2–50ns), and compatibility with ±4.5V to ±20V dual or +9V to +36V single supplies.

Technical Context

The DG413FEUE+T integrates four independent SPST switches in a single 16-pin TSSOP package, each formed by parallel N- and P-channel FETs enabling low R_ON and bidirectional rail-to-rail signal conduction. Its dual comparator-based fault detection circuitry monitors COM_, NO_, and NC_ terminals continuously against V+ and V−.

During overvoltage faults, internal FETs turn off within 20ns, isolating the affected terminal into high-impedance state regardless of control logic or supply status. The device remains fully functional with asymmetric dual supplies (e.g., V+ = +12V, V− = −5V), provided |V+ − V−| ≤ 44V.

FAQ

What is the maximum supply voltage range supported by DG413FEUE+T?

DG413FEUE+T operates with dual supplies from ±4.5V to ±20V (|V+ − V−| ≤ 44V) or a single supply from +9V to +36V. It tolerates absolute maximum ratings of V+ = −0.3V to +44V and V− = −44V to +0.3V. Exceeding these ranges risks permanent damage, as confirmed in the Absolute Maximum Ratings table.

Does DG413FEUE+T provide true rail-to-rail analog signal handling?

Yes, DG413FEUE+T supports analog signals from V− to V+ on all COM_, NO_, and NC_ terminals - verified across temperature and supply conditions. This is enabled by its parallel N/P-FET architecture and internal level-shifting logic, allowing undistorted passage of full-scale signals in ±15V or +12V systems.

How does fault protection behave when power is removed from DG413FEUE+T?

With power off (V+ = V− = 0), DG413FEUE+T maintains ±40V fault protection on all COM_, NO_, and NC_ terminals. During a fault, those pins become virtual open circuits with microampere-level leakage - ensuring downstream circuitry remains isolated even during complete power loss.

Is DG413FEUE+T pin-compatible with the legacy DG413?

Yes, DG413FEUE+T has identical pinout and footprint to the non-fault-protected DG413. All IN_, COM_, NO_, NC_, V+, V−, GND, and N.C. assignments match exactly - enabling direct replacement in existing PCBs without layout modification or signal integrity revalidation.

What is the break-before-make timing specification for DG413FEUE+T?

DG413FEUE+T guarantees a break-before-make delay of 2ns minimum to 50ns maximum (typical 15ns) between NC and NO paths during switching - measured at +25°C with ±10V signal, 100Ω load, and 10pF capacitance. This parameter is exclusive to DG413F variants and prevents signal shorting.
