Product details
Overview
DG413DY from Vishay Siliconix is a precision monolithic quad SPST analog switch IC with two normally open (NO) and two normally closed (NC) switches, 44 V supply rating, 15 V analog signal range, 25 Ω typical on-resistance at ±15 V supplies, and 110 ns turn-on time-used in precision data acquisition systems requiring break-before-make switching action.
For engineers reviewing the DG413DY datasheet, DG413DY pinout, DG413DY application, or DG413DY equivalent, key selection criteria include dual logic polarity support (SW1/SW4 active-high, SW2/SW3 active-low), ±15 V or 12 V single-supply operation, low 5 pC charge injection, and SOIC-16 packaging for space-constrained industrial instrumentation.
Technical Context
The DG413DY implements four independent CMOS transmission gates fabricated on a high-voltage silicon gate process with epitaxial latchup protection. Its internal logic decodes two digital inputs to drive two NO and two NC switches simultaneously, enabling break-before-make timing with 25 ns guaranteed delay between channel transitions.
It supports bipolar (±15 V) and unipolar (12 V) supply configurations, where VL is tied to V+ in single-supply mode. Analog signal handling is symmetrical-each switch conducts bidirectionally with full rail-to-rail voltage blocking when off, and maintains <0.25 nA leakage across –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full-range signal switching without clipping in dual-supply precision systems |
| rDS(on) Typ. | 25 Ω at ±15 V - ensures minimal signal attenuation and gain error in sensor front-ends |
| tON / tOFF | 110 ns / 100 ns - enables sub-microsecond multiplexing in high-speed data loggers |
| Charge Injection | 5 pC - limits output voltage step errors in sample-and-hold or integrator circuits |
| OIRR | 68 dB - provides strong isolation between active and inactive channels at 1 MHz |
| Supply Voltage Max | 44 V - allows robust operation in industrial environments with transient overvoltage |
| Logic Compatibility | TTL/CMOS - interfaces directly with microcontrollers and FPGAs without level-shifting |
Pinout & Package
Package: 16-pin narrow SOIC (SOIC-16), 3.9 mm width, JEDEC MS-012AC compliant, rated for –40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2, IN3, IN4 | Digital control inputs | IN1/IN4 active-high drives SW1/SW4 ON; IN2/IN3 active-low drives SW2/SW3 ON |
| S1–S4 | Switch source terminals | Connect to analog signal sources; bidirectional conduction path when switch is closed |
| D1–D4 | Switch drain terminals | Connect to analog signal destinations; identical electrical behavior to Sx pins |
| V+, V– | Analog supply rails | Support ±15 V dual supply or 12 V single supply (V– = GND); define analog signal swing limits |
| GND | Ground reference | Return path for logic and analog grounds; must be low-impedance for noise immunity |
| VL | Logic supply input | Accepts 5 V TTL/CMOS logic levels; decoupled internally to prevent supply coupling into analog path |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 25 ns minimum delay prevents momentary shorting between channels in multiplexer designs |
| Low on-resistance flatness | ±2 Ω variation over ±10 V signal range minimizes THD in audio and instrumentation paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4613CPD+ | Higher 45 Ω rDS(on), 130 ns tON, but offers fault-protection and overvoltage shutdown | Preferred in safety-critical systems where input overvoltage may exceed ±20 V | Select MAX4613CPD+ only if fault protection is required; DG413DY delivers lower distortion in precision signal paths |
| ADG413BRZ | Lower 20 Ω rDS(on), 100 ns tON, but requires separate VL and VDD pins and lacks LCC package option | Better suited for new designs targeting lowest on-resistance and fastest switching | Choose ADG413BRZ for highest performance; DG413DY remains optimal for legacy SOIC-16 footprint compatibility and cost-sensitive volume production |
Compared with MAX4613CPD+ and ADG413BRZ, the DG413DY balances proven reliability, SOIC-16 footprint compatibility, and optimized trade-offs among on-resistance, switching speed, and charge injection-making it ideal for established industrial data acquisition platforms where BOM stability and long-term sourcing matter.

FAQ
What is the maximum supply voltage rating for the DG413DY?
The DG413DY supports up to 44 V across V+ and V– terminals, with absolute maximum ratings of ±25 V from GND to V– and V+ to V–. This wide supply range enables operation in industrial environments with significant rail transients, and allows use with 12 V single-supply or ±15 V dual-supply configurations without external regulation. The DG413DY maintains specified performance across its full rated supply range.
Does the DG413DY support single-supply operation?
Yes, the DG413DY supports true single-supply operation from 5 V to 44 V. In this mode, V– is connected to GND, V+ is tied to VL, and analog signals swing from 0 V to V+. The device is fully characterized at 12 V single supply, with rDS(on) ≤100 Ω and tON ≤400 ns over temperature. Logic thresholds scale with VL, ensuring reliable switching even at reduced supply voltages.
How does the DG413DY implement break-before-make switching?
The DG413DY integrates internal timing circuitry that guarantees a minimum 25 ns delay between turn-off of one switch pair and turn-on of the complementary pair (e.g., SW1 OFF before SW2 ON). This is explicitly verified per Figure 3 in the datasheet and ensures no momentary short-circuit occurs during channel transitions-critical for preventing signal corruption in multiplexer and relay-replacement applications using the DG413DY.
What is the charge injection specification for the DG413DY, and why does it matter?
The DG413DY specifies 5 pC typical charge injection at room temperature with CL = 10 nF. This parameter quantifies the net charge dumped onto the load capacitor during switching, directly causing voltage glitches in sample-and-hold, integrator, or filter circuits. At 5 pC, the resulting step error is <0.5 mV into a 10 nF capacitor-enabling accurate DC-coupled measurements in 16-bit data acquisition systems using the DG413DY.
Can the DG413DY be used in high-temperature industrial environments?
Yes, the DG413DY is rated for operation from –40°C to +85°C, with full parametric performance guaranteed across this range. Its high-voltage silicon gate process includes an epitaxial layer to prevent latchup, and leakage currents remain below ±0.25 nA even at +85°C. For extended temperature applications beyond +85°C, the DG413AK/883 variant (–55°C to +125°C) is available-but the standard DG413DY meets requirements for most industrial control and monitoring systems.
