Product details
Overview
DG413FDJ+ from Maxim Integrated is a quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels, fault-protected up to ±36V with power on and ±40V with power off, 35Ω max on-resistance at ±15V, 1.5Ω max channel-to-channel RON match, and rail-to-rail signal handling - used in redundant avionics signal routing where overvoltage resilience and channel independence are critical.
For engineers reviewing the DG413FDJ+ datasheet, DG413FDJ+ pinout, DG413FDJ+ application, or DG413FDJ+ equivalent, this page delivers verified electrical specs, fault-protection behavior under dual/single supply, break-before-make timing for mixed NO/NC operation, package-specific thermal limits, and direct alternatives with documented functional trade-offs.
Technical Context
The DG413FDJ+ implements dual-FET (N+P parallel) switch architecture per channel, enabling low RON and true bidirectional rail-to-rail conduction. Its fault protection uses independent high- and low-voltage comparators on each COM/NO/NC terminal, forcing high-impedance isolation within 20ns when signals exceed V+ + 0.05V or V− − 0.05V.
It supports asymmetric dual supplies (±4.5V to ±20V, ΔV ≤ 44V) or single +9V to +36V operation with TTL/CMOS-compatible logic thresholds (VIH = 2.4V, VIL = 0.8V). The DG413F variant specifically provides break-before-make timing (2–50ns typ) between its paired NO/NC switches to prevent momentary shorting during state transitions.
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 (ΔRON) | 1.5 Ω max between channels - enables matched gain/phase in multi-channel instrumentation front-ends. |
| Fault protection range | ±36V with power on, ±40V with power off - protects downstream circuitry from transient overvoltages without external clamps. |
| Break-before-make delay (tBBM) | 2–50 ns typ - prevents cross-conduction during switching of complementary NO/NC pairs in safety-critical systems. |
| Off-isolation | −65 dB at 1 MHz - suppresses crosstalk between active and inactive channels in high-density signal routing. |
| Charge injection | 5 pC - minimizes glitch-induced settling errors in sample-and-hold or multiplexed ADC interfaces. |
| Supply range | ±4.5V to ±20V dual or +9V to +36V single - supports legacy ±15V industrial rails and modern high-voltage sensor interfaces. |
Pinout & Package
Package: 16-pin plastic DIP (PDIP), outline 21-0043, RoHS-compliant, with 0.3-inch width and through-hole mounting. Thermal derating: 10.53 mW/°C above +70°C; max continuous power dissipation = 842 mW at TA = +70°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; CMOS/TTL-compatible with VIH = 2.4V, VIL = 0.8V - directly driven by microcontrollers or FPGAs without level-shifting. |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals; fault-protected up to ±40V - serve as bidirectional signal hubs for multiplexed sensor or actuator paths. |
| 3, 6 | NO1, NO4 | Normally open analog terminals; isolated from COM when IN = 0 - enable default-open signal paths in fail-safe monitoring circuits. |
| 11, 14 | NC2, NC3 | Normally closed analog terminals; conduct to COM when IN = 0 - maintain default continuity for backup or diagnostic channels. |
| 4 | V− | Negative supply rail; connect to GND for single-supply use - sets lower fault threshold and powers internal comparator bias networks. |
| 5 | GND | Digital ground reference; decoupled via 0.1 µF capacitor - stabilizes logic thresholds and reduces noise coupling into analog paths. |
| 12 | N.C. | No internal connection - left unconnected on PCB; no routing or thermal impact required. |
| 13 | V+ | Positive supply rail; bypassed with 0.1 µF capacitor - defines upper fault limit and powers analog switch gates and logic translators. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Signals from V− to V+ pass unattenuated in either direction - eliminates clipping in ±10V sensor or audio signal chains. |
| Power-off fault protection | ±40V tolerance on COM/NO/NC with V+/V− unpowered - safeguards against hot-plug transients or system-level brownouts. |
| No supply sequencing required | V+ and V− may be powered in any order without latch-up or damage - simplifies power management in multi-rail systems. |
| All-switches-off behavior | Switches disable automatically when V+ is off (even if V− is active) - enforces safe default state in partial-power conditions. |
| 20 ns fault response time | Isolates faulty node within 20 ns of overvoltage detection - prevents energy transfer to sensitive downstream components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4713DJP+ | Same pinout, identical NO/NC configuration, but rated only for ±15V supplies and lacks ±40V power-off fault protection. | Suitable for cost-sensitive industrial controls where full ±40V off-state protection is unnecessary. | Select MAX4713DJP+ only if operating exclusively within ±15V rails and no field-service hot-swap risk exists. |
| ADG413BNZ | Quad SPST with 2 NO/2 NC, but no integrated fault protection - requires external ±36V clamping diodes and current-limiting resistors. | Used where board space allows discrete protection and higher RON (60 Ω) is acceptable. | Choose ADG413BNZ only when leveraging existing protection circuitry or when sourcing from alternate suppliers with longer lead times. |
Compared with MAX4713DJP+, DG413FDJ+ adds ±40V power-off fault tolerance and wider supply range (+9V to +36V), making it superior for field-deployed equipment; versus ADG413BNZ, DG413FDJ+ integrates protection, reducing component count and layout complexity despite higher unit cost.

FAQ
What is the maximum fault voltage the DG413FDJ+ can withstand with power applied?
The DG413FDJ+ sustains ±36V on COM/NO/NC terminals with power applied (V+ and V− active), per Absolute Maximum Ratings. This applies regardless of supply voltage within the ±4.5V to ±20V range. Exceeding ±36V risks permanent damage, even momentarily. DG413FDJ+ maintains this rating across its full −40°C to +85°C operating temperature range.
Does the DG413FDJ+ require specific power supply sequencing?
No - the DG413FDJ+ has no power supply sequencing requirement. V+ and V− may be powered in any order, and the device remains undamaged. When V+ is unpowered (regardless of V− state), all switches turn off automatically. This behavior is inherent to its internal fault-protection architecture and is guaranteed across all operating conditions.
How does the break-before-make timing work in the DG413FDJ+?
The DG413FDJ+ implements break-before-make (tBBM) only between its paired NO and NC switches (e.g., NO1/NC1, NO4/NC3), with typical delay of 2–50 ns. This prevents momentary shorting when toggling complementary paths. It does not apply between independent channels (e.g., COM1–NO1 vs. COM2–NC2). tBBM is measured under RL = 100Ω, CL = 10pF, and is process- and temperature-dependent.
Can the DG413FDJ+ operate from a single +12V supply?
Yes - the DG413FDJ+ operates from a single +9V to +36V supply by connecting V− to GND. At +12V, RON is 35 Ω max, tON/tOFF are 120–315 ns / 70–140 ns, and fault protection remains ±36V with power on. Logic thresholds remain TTL/CMOS-compatible (VIH = 2.4V, VIL = 0.8V), enabling direct interface with +3.3V or +5V controllers.
What is the thermal performance of the DG413FDJ+ in its PDIP package?
In the 16-pin plastic DIP package, DG413FDJ+ has a thermal derating factor of 10.53 mW/°C above +70°C ambient. Its maximum continuous power dissipation is 842 mW at TA = +70°C. Junction temperature must not exceed +150°C. For sustained operation near thermal limits, PCB copper area and airflow should be validated per JEDEC JESD51 standards.
