Product details
Overview
DG405BDY-T1-E3 from Vishay Siliconix is a quad SPST analog switch in 16-pin narrow SOIC package, designed for bidirectional signal routing with ±15 V analog range, 23 Ω typical on-resistance, 100 ns turn-on time, and 44 V max supply rating - ideal for audio/video switching and test equipment requiring low leakage and high-speed performance.
For engineers reviewing the DG405BDY-T1-E3 datasheet, DG405BDY-T1-E3 pinout, DG405BDY-T1-E3 application, or DG405BDY-T1-E3 equivalent, key selection criteria include guaranteed break-before-make timing (in DG403B only), TTL/CMOS compatibility, single- or dual-supply operation (5–36 V or ±5–±22 V), and lead-free matte tin terminations indicated by the "-E3" suffix.
Technical Context
The DG405BDY-T1-E3 implements four independent SPST switches arranged as two matched pairs, each with symmetrical conduction in both directions when on and blocking up to ±15 V analog signals. It uses Vishay's high-voltage silicon gate process to achieve 44 V supply rating and flat RDS(on) across the full analog range.
Control logic is TTL/CMOS compatible (VIL ≤ 0.8 V, VIH ≥ 2.4 V), enabling direct interfacing with microcontrollers and logic families. Unlike the DG403B, the DG405B does not guarantee break-before-make switching - its truth table shows simultaneous on/off control of paired switches without inherent delay coordination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog signal range | ±15 V - supports rail-to-rail bipolar signal switching without clipping |
| On-resistance (RDS(on)) | 23 Ω typ. - ensures minimal signal attenuation and voltage drop in precision analog paths |
| Turn-on time (ton) | 100 ns typ. - enables high-speed multiplexing in data acquisition and instrumentation |
| Switch off leakage | ±0.5 nA max. - preserves signal integrity in sample-and-hold and high-impedance sensor interfaces |
| Supply voltage range | Single: 5–36 V; Dual: ±5–±22 V - allows flexible power architecture in portable and industrial systems |
| Charge injection | 60 pC typ. - limits voltage glitch at switch transitions in integrator and peak detector circuits |
| Off-isolation (OIRR) | –81.7 dB typ. at 1 MHz - suppresses crosstalk between inactive channels in multi-source systems |
Pinout & Package
Package: 16-pin narrow SOIC (JEDEC MS-012), 3.90 mm × 9.90 mm body, 1.27 mm pitch, matte tin (Pb-free) terminations per "-E3" suffix.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7 | Switch drain (D1–D4) | Output terminals for analog signal routing; bidirectional conduction when switch enabled |
| 2, 4, 6, 8 | Switch source (S1–S4) | Input terminals; electrically interchangeable with drains under on-state conditions |
| 9, 10 | Logic inputs (IN1, IN2) | Active-high TTL/CMOS-compatible controls for two SPST pairs (IN1 → S1/D1 & S2/D2; IN2 → S3/D3 & S4/D4) |
| 11, 12 | V−, GND | Negative supply and ground reference; required for dual-supply operation and bias stability |
| 13, 14 | V+, NC | Positive supply input (pin 13); pin 14 is no-connect - must be left unconnected |
| 15, 16 | NC, NC | No-connect pins - no internal connection; must remain unconnected per datasheet |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional analog switching | Enables symmetric signal routing in AC-coupled or bipolar systems without polarity constraints |
| Low on-resistance flatness | RDS(on) variation < 5 Ω over ±15 V range - maintains consistent gain and linearity in precision amplifiers |
| Ultra-low leakage current | ≤ 0.5 nA off-state leakage - critical for long-interval sample-and-hold and high-impedance medical sensors |
| TTL/CMOS logic interface | Direct drive from 3.3 V or 5 V microcontrollers without level-shifting circuitry |
| Lead-free construction | 100 % matte tin terminations (per "-E3") - compliant with RoHS and JEDEC J-STD-020 reflow profiles |
Applications
| Audio Source Selection | Test Equipment Multiplexing |
|---|---|
Use Scenario: Routing stereo analog inputs (e.g., phono, line-in, DAC outputs) to a common amplifier or ADC path. IC Role / Device Role / Timing Role: Quad SPST switch providing isolated, low-distortion signal paths with simultaneous pair enablement. Use Value: 23 Ω RDS(on) and –81.7 dB off-isolation prevent channel bleed and preserve dynamic range in consumer/pro-audio gear. | Use Scenario: Scanning multiple sensor outputs (thermocouples, strain gauges) into a shared precision ADC in automated test systems. IC Role / Device Role / Timing Role: Analog multiplexer front-end with fast 100 ns switching and sub-nA leakage for accurate DC measurements. Use Value: ±15 V analog range accommodates wide-output transducers; 60 pC charge injection minimizes settling error post-switching. |
| Dual-Slope Integrator Control | Video Signal Switching |
Use Scenario: Selecting between integration capacitors (C1/C2) and configuring charge/discharge paths in precision analog-to-digital converters. IC Role / Device Role / Timing Role: Precision timing-path switch enabling capacitor reconfiguration without introducing offset or drift. Use Value: Flat RDS(on) vs. voltage ensures linear ramp generation; low leakage prevents capacitor self-discharge during hold phases. | Use Scenario: Switching composite video, S-video, or RGB signals between multiple sources (cameras, GPUs, playback units) in broadcast or AV distribution hardware. IC Role / Device Role / Timing Role: High-bandwidth analog switch supporting baseband video frequencies with minimal insertion loss. Use Value: 39 pF on-capacitance and –94.8 dB crosstalk maintain signal fidelity up to 10 MHz; SOIC package supports compact PCB layout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Quad SPST, 35 Ω RDS(on), 125 ns ton, ±15 V range, 16-pin SOIC | Higher on-resistance and slower switching limit use in high-speed sampling systems | Select when lower cost or legacy MAXIM design compatibility is prioritized over speed and RDS(on) |
| ADG1419BRUZ | Quad SPST, 1.3 Ω RDS(on), 120 ns ton, ±15 V range, 16-pin TSSOP | Lower on-resistance improves accuracy but requires tighter layout for thermal management | Choose for ultra-low distortion in precision instrumentation where 1.3 Ω RDS(on) justifies higher cost and smaller footprint |
Compared with DG405BDY-T1-E3, the MAX4617ESE+ trades speed and on-resistance for broader vendor support, while the ADG1419BRUZ delivers superior analog performance at higher cost and different package thermal behavior - all three require verification of logic-level compatibility and PCB pad layout.

FAQ
What is the maximum supply voltage rating for DG405BDY-T1-E3?
The DG405BDY-T1-E3 has an absolute maximum V+ to V− rating of 44 V. Its recommended operating range is single supply 5–36 V or dual supply ±5 V to ±22 V. Exceeding these limits risks permanent damage, and operation above 44 V violates absolute maximum ratings per Vishay document 73069.
Does DG405BDY-T1-E3 support break-before-make switching?
No, DG405BDY-T1-E3 does not guarantee break-before-make timing. That feature is explicitly specified only for the DG403B variant. The DG405B truth table shows simultaneous on/off control of switch pairs, with no built-in delay coordination - external timing control is required if break-before-make behavior is needed.
What does the "-E3" suffix mean in DG405BDY-T1-E3?
"-E3" indicates 100 % matte tin (Pb-free) device terminations per Vishay's lead-free designation system. It confirms RoHS compliance and compatibility with standard SnPb and lead-free reflow profiles. The "T1" denotes tape-and-reel packaging (3,000 units per reel), and "DY" specifies the 16-pin narrow SOIC package.
Can DG405BDY-T1-E3 operate from a single 5 V supply?
Yes, DG405BDY-T1-E3 supports single-supply operation from 5 V to 36 V. At 5 V, it maintains TTL/CMOS-compatible logic thresholds (VIL ≤ 0.8 V, VIH ≥ 2.4 V) and delivers usable analog switching across 0–5 V signals. However, the full ±15 V analog range requires dual supplies (e.g., ±15 V).
How many independent switches does DG405BDY-T1-E3 contain?
DG405BDY-T1-E3 contains four independent SPST (single-pole, single-throw) analog switches, organized as two logically paired sets: IN1 controls S1/D1 and S2/D2; IN2 controls S3/D3 and S4/D4. Each switch conducts bidirectionally and shares no internal coupling beyond shared supply rails.
