Product details
Overview
DG413FDY+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 DG413FDY+T datasheet, DG413FDY+T pinout, DG413FDY+T application, or DG413FDY+T equivalent, key selection criteria include fault-protection voltage limits, break-before-make timing (2–50 ns), on-resistance matching (≤1.5Ω), dual-supply operation (±4.5V to ±20V), and SOIC-16 package compatibility with legacy DG413 designs.
Technical Context
The DG413FDY+T integrates four independent SPST switches in one SOIC-16 package, with two NO and two NC configurations controlled by separate digital inputs. Its internal architecture uses parallel N- and P-channel FETs per channel to achieve low RON and true bidirectional rail-to-rail conduction.
Fault protection operates via dual comparators monitoring COM_, NO_, and NC_ against V+ and V−; during overvoltage, all affected terminals become high-impedance within 20 ns. The device remains fully functional across −40°C to +85°C and supports single-supply (+9V to +36V) or dual-supply (±4.5V to ±20V) operation without sequencing requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 35 Ω max at ±15V, +25°C - ensures minimal signal attenuation and voltage drop in precision analog paths. |
| RON match between channels | 1.5 Ω max at ±15V, +25°C - critical for matched gain/phase in differential or multi-channel signal routing. |
| Fault protection range | ±36V with power on, ±40V with power off - enables robust operation in harsh industrial or avionics environments where transients exceed supply rails. |
| Break-before-make time (DG413F only) | 2–50 ns at +25°C - prevents momentary shorting during channel switching in sensitive analog multiplexing. |
| Logic input thresholds | VIL = +0.8V, VIH = +2.4V - guarantees interoperability with both TTL and CMOS logic under ±15V or +12V supply conditions. |
| Supply range | ±4.5V to ±20V dual or +9V to +36V single - supports wide-range industrial power architectures without external level-shifting. |
| Turn-on/turn-off time | 70–250 ns (tON), 55–140 ns (tOFF) - enables fast switching in automated test equipment and data acquisition sampling control. |
Pinout & Package
Package: 16-pin SOIC (Small Outline Integrated Circuit), RoHS-compliant, standard JEDEC MS-012 outline (Outline Number 21-0041). Thermal derating: 8.7 mW/°C above +70°C; max continuous power dissipation = 696 mW at +70°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; active-high logic drives channel state (NO/NC) with TTL/CMOS thresholds. |
| 2, 7, 10, 15 | COM1–COM4 | Common analog terminals; bidirectional signal path shared between NO and NC contacts per channel. |
| 3, 6 | NO1, NO4 | Normally open analog terminals; connect to COM when corresponding IN is high (DG413F configuration). |
| 11, 14 | NC2, NC3 | Normally closed analog terminals; connect to COM when corresponding IN is low (DG413F configuration). |
| 4 | V− | Negative supply rail; must be connected to GND for single-supply operation; bypass with 0.1 µF capacitor. |
| 5 | GND | Digital ground reference; separates logic domain from analog signal paths; no galvanic connection to COM/NO/NC. |
| 12 | N.C. | No internal connection; left unconnected on PCB; no electrical function or thermal role. |
| 13 | V+ | Positive supply rail; powers internal logic and gate drivers; bypass with 0.1 µF capacitor to GND. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Signals from V− to V+ pass unattenuated through ON switches - eliminates clipping in ±10V instrumentation front-ends. |
| Fault response time | 20 ns typical turn-off delay during overvoltage - protects downstream circuitry before transient energy propagates. |
| All-switches-off behavior | Switches disable automatically when V+ is unpowered (even if V− is active) - prevents unintended analog leakage during brownout. |
| Pin compatibility | Identical pinout to industry-standard DG413 - enables drop-in replacement in existing layouts without redesign. |
| Charge injection | 5 pC typical - minimizes voltage glitch on sampled-hold nodes in precision ADC driver circuits. |
Applications
| Industrial Process Control | Avionics Signal Management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4713ESE+ | Same 2-NO/2-NC configuration, but rated for +3V/+5V supplies only; lacks ±36V fault protection. | Suitable for low-voltage portable instrumentation; not viable for industrial ±15V systems. | Select MAX4713ESE+ only when supply is ≤+5V and fault exposure is limited to <±10V. |
| ADG1413BRUZ | Quad SPST, 2-NO/2-NC, ±15V-rated, but fault protection limited to ±20V; higher RON (40Ω typ). | Acceptable for lab-grade test gear with controlled ESD; insufficient for avionics-level surge immunity. | Choose ADG1413BRUZ if board space requires TSSOP-16 and ±20V fault margin suffices. |
Compared with MAX4713ESE+ and ADG1413BRUZ, DG413FDY+T uniquely delivers ±36V fault protection with rail-to-rail operation across ±4.5V–±20V supplies - making it the only option qualified for high-reliability industrial and aerospace signal routing where transient immunity and supply flexibility are non-negotiable.

FAQ
What is the maximum fault voltage the DG413FDY+T can withstand with power applied?
The DG413FDY+T withstands up to ±36V on COM_, NO_, or NC_ terminals when power is applied - verified under ±15V dual-supply conditions per the Absolute Maximum Ratings table. This rating applies regardless of whether V+ and V− are symmetrical, provided their difference stays within ±44V.
Does the DG413FDY+T support single-supply operation, and what is the valid voltage range?
Yes, DG413FDY+T supports single-supply operation with V− tied to GND and V+ ranging from +9V to +36V. At +12V, it maintains 35Ω max RON, TTL/CMOS logic compatibility, and full fault protection (±36V with power on, ±40V with power off).
How does the break-before-make timing work on the DG413FDY+T, and why is it specified only for this variant?
The DG413FDY+T implements break-before-make switching exclusively on its two NO/NC pairs (channels 1/4 and 2/3), with tBBM = 2–50 ns at +25°C. This prevents signal shorting during reconfiguration - a feature absent in DG411F (all-NC) and DG412F (all-NO), which lack complementary contact types per channel.
Is the DG413FDY+T pin-compatible with the original DG413, and what does that mean for PCB layout?
Yes, DG413FDY+T uses identical SOIC-16 pinout and footprint as the non-fault-protected DG413. That means no PCB changes are required - all COM_, NO_, NC_, IN_, V+, V−, and GND connections map directly, enabling seamless reliability upgrades in deployed systems.
What is the on-resistance temperature coefficient of the DG413FDY+T, and how does it affect precision applications?
At ±15V, DG413FDY+T RON increases from ~25Ω at +25°C to ~45Ω at +85°C (per Figure DG411 toc02). This +0.2Ω/°C drift must be accounted for in high-accuracy current-sensing or gain-setting networks where resistance stability directly impacts measurement error.
