Product details
Overview
DG401BDY-E3 from Vishay Siliconix is a dual single-pole single-throw (SPST) analog switch IC designed for bidirectional signal routing in precision analog systems. It features 23 Ω typical on-resistance, ±15 V analog signal range, 100 ns typical turn-on time, and operates from dual supplies up to ±22 V or single supply up to 36 V - making it suitable for battery-powered audio multiplexing and test equipment front-end switching.
For engineers reviewing the DG401BDY-E3 datasheet, DG401BDY-E3 pinout, DG401BDY-E3 application, or DG401BDY-E3 equivalent, key selection criteria include guaranteed break-before-make timing (not applicable to DG401B), low 40 pA channel-on leakage, flat RDS(on) over full analog range, TTL/CMOS logic compatibility, and lead-free SOIC-16 packaging with 100% matte tin terminations.
Technical Context
The DG401BDY-E3 implements two independent SPST switches built on Vishay's high-voltage silicon gate process, enabling symmetric conduction in both directions when on and blocking up to 30 V peak-to-peak when off. Its on-resistance remains flat across the full ±15 V analog input range due to matched channel geometry and bias optimization.
It supports single-supply operation (5 V to 36 V) and dual-supply operation (±5 V to ±22 V), with logic thresholds defined at ≤0.8 V for low and ≥2.4 V for high. Charge injection is limited to 60 pC, minimizing transient errors in sample-and-hold and precision measurement circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RDS(on)) | 23 Ω typ. - ensures minimal signal attenuation and gain error in low-impedance analog paths |
| Analog signal range | ±15 V - supports rail-to-rail operation with ±15 V op-amp interfaces and industrial sensor signals |
| Turn-on time (ton) | 100 ns typ. - enables fast channel switching in multi-channel data acquisition at >1 MHz sampling rates |
| Channel-on leakage (ID(on)) | 0.04 nA typ. - preserves accuracy in high-impedance sample-and-hold and integrator applications |
| Supply voltage range | Single: 5–36 V; Dual: ±5 V to ±22 V - allows flexible integration into mixed-signal systems with varied power domains |
| Charge injection | 60 pC - limits voltage step error on hold capacitors below 1 LSB in 14-bit+ systems with ≥10 nF hold capacitance |
| Off-isolation (OIRR) | –81.7 dB - suppresses crosstalk between inactive channels in multi-source audio or instrumentation routing |
Pinout & Package
Package: 16-pin narrow SOIC (JEDEC MS-012), 3.9 mm × 9.9 mm body, 1.27 mm pitch, lead-free with 100% matte tin terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | V+ | Positive supply rail - must be ≥ V− + 5 V; max 44 V differential to V− |
| 8, 15 | V− | Negative supply rail - supports bipolar operation down to –22 V |
| 4, 5, 12, 13 | NC | No-connect - internally unconnected; must remain floating or grounded per layout guidelines |
| 2, 7, 10, 11 | S1, D1, S2, D2 | Source/drain terminals of two independent SPST switches - bidirectional, interchangeable |
| 3, 6 | IN1, IN2 | Digital control inputs - TTL/CMOS compatible; logic high ≥2.4 V enables corresponding switch |
| 9 | GND | Analog/digital reference ground - separate from power supply return in sensitive layouts |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional analog conduction | Equal RDS(on) and leakage in either direction - eliminates polarity constraints in AC-coupled signal paths |
| Flat on-resistance vs. voltage | ΔRDS(on) ≤ 3 Ω over ±15 V - maintains consistent gain and linearity across full signal swing |
| Low charge injection (60 pC) | Minimizes hold-step error in precision sample-and-hold circuits without requiring large compensation capacitance |
| Lead-free SOIC-16 package | RoHS-compliant 100% matte tin terminations - eliminates Pb-based solder compatibility concerns and meets IPC-J-STD-020 moisture sensitivity level 1 |
| Wide supply flexibility | Operates from single 5–36 V or dual ±5 V to ±22 V - simplifies power architecture in mixed-signal PCBs |
Applications
| Audio Source Multiplexer | Test Equipment Signal Routing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Single SPST, 35 Ω RDS(on), 125 ns ton, ±15 V range, 16-pin SOIC | Lower channel count; higher on-resistance increases gain error in precision gain stages | Preferred where only one switch is needed and lower cost outweighs performance trade-offs |
| ADG1419BRUZ | Dual SPST, 1.3 Ω RDS(on), 120 ns ton, ±15 V range, 16-pin TSSOP | Lower on-resistance improves accuracy but requires tighter layout control due to smaller TSSOP footprint | Selected when sub-ohm on-resistance is critical and board space permits fine-pitch assembly |
Compared with DG401BDY-E3, MAX4617ESE+ offers reduced channel count and higher RDS(on) at lower cost, while ADG1419BRUZ delivers significantly lower on-resistance in a smaller package - requiring trade-offs in layout complexity, thermal dissipation, and BOM cost for precision applications.

FAQ
What is the maximum supply voltage rating for DG401BDY-E3?
The DG401BDY-E3 has an absolute maximum V+ to V− rating of 44 V. For reliable operation, the recommended dual-supply range is ±5 V to ±22 V, and the single-supply range is 5 V to 36 V. Exceeding these limits risks permanent damage, as confirmed in the Absolute Maximum Ratings table of Vishay document 73069.
Does DG401BDY-E3 support break-before-make switching?
No, DG401BDY-E3 does not implement break-before-make switching. That feature is guaranteed only for the DG403B variant (four SPST switches in NO/NC configuration). The DG401BDY-E3 contains two independent SPST switches with no timing interlock between them - each operates solely based on its dedicated INx control input.
What is the typical on-resistance flatness over the analog input range for DG401BDY-E3?
The DG401BDY-E3 exhibits ΔRDS(on) ≤ 3 Ω over ±5 V and ≤ 5 Ω over full ±15 V analog range at temperature extremes, per specification table in Vishay document 73069. This flatness ensures consistent signal transfer and minimal harmonic distortion in audio and instrumentation paths.
Can DG401BDY-E3 operate from a single 5 V supply?
Yes, DG401BDY-E3 supports single-supply operation from 5 V to 36 V. At 5 V, it maintains TTL/CMOS-compatible logic thresholds (≤0.8 V low, ≥2.4 V high) and delivers functional analog switching with RDS(on) ≤ 45 Ω and ton ≤ 150 ns, as verified in the "Specifications" section of the datasheet.
Is DG401BDY-E3 pin-compatible with the legacy DG401?
Yes, DG401BDY-E3 is a direct replacement for DG401 in SOIC-16 packaging, retaining identical pinout, electrical specifications, and functional behavior. The "B" suffix denotes improved performance (e.g., faster switching, lower leakage), and the "-E3" suffix confirms 100% matte tin lead finish - both backward-compatible with DG401 layouts and firmware.
