Product details
Overview
DG406BDW-E3 from Vishay Siliconix is a 16-channel single-ended CMOS analog multiplexer with TTL-compatible control inputs, 45 Ω on-resistance, 115 ns transition time, and ±20 V dual-supply operation. It routes one of sixteen analog inputs to a common output under 4-bit binary address control and supports break-before-make switching for signal integrity in data acquisition systems.
For engineers reviewing the DG406BDW-E3 datasheet, DG406BDW-E3 pinout, DG406BDW-E3 application, or DG406BDW-E3 equivalent, this device is selected for high-accuracy, low-glitch analog signal routing where channel count, low charge injection (11 pC), and rail-to-rail signal handling are critical design requirements.
Technical Context
The DG406BDW-E3 implements a silicon-gate CMOS architecture with epitaxial latchup protection and operates across ±5 V to ±20 V dual supplies or 5 V to 40 V single supply. Its decoder/driver stage accepts TTL-level A0–A3 and EN inputs to select one of 16 source channels (S1–S16) to the drain (D) output.
Each channel exhibits matched on-resistance (ΔRDS(on) ≤ 5 %), sub-nA off-leakage (±5 nA max), and −86 dB off-isolation at 1 MHz. Break-before-make timing (tOPEN ≥ 10 ns) prevents input shorting during channel transitions, and enable-controlled reset allows stacking multiple devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel configuration | 16:1 single-ended analog multiplexer - selects one of 16 inputs to common output |
| On-resistance (RDS(on)) | 45 Ω typical (±15 V supplies) - ensures minimal signal attenuation and gain error |
| Transition time (tTRANS) | 115 ns typical - enables >5 MHz switching rate in high-speed data acquisition |
| Charge injection (Q) | 11 pC typical - reduces voltage glitch on sampled-hold nodes in precision ADC front-ends |
| Analog signal range | ±15 V (dual supply) or 0–12 V (single supply) - supports industrial and medical sensor interfaces |
| Off-isolation (OIRR) | −86 dB at 1 MHz - suppresses crosstalk between unselected channels in multi-signal systems |
| Supply voltage range | ±5 V to ±20 V dual or 5 V to 40 V single - accommodates legacy and battery-powered designs |
Pinout & Package

| 19 | V− | Negative supply rail; supports down to −20 V in dual mode; GND reference in single-supply use |
| 20 | GND | Ground reference for logic and substrate; must be connected even in dual-supply operation |
| 21, 22, 23, 24 | A0–A3 | 4-bit binary address inputs; TTL-compatible (0.8 V/2.4 V thresholds); determine active channel |
| 25 | EN | Enable input; logic low disables all switches (high-impedance state); enables stacking and power gating |
| 26, 27, 28 | NC | No-connect pins; must remain unconnected per datasheet; no internal connection or function |
Key Features
| Feature | Design Value |
|---|---|
| Low on-resistance matching | ΔRDS(on) ≤ 5 % - minimizes gain mismatch across channels in multi-input instrumentation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX406CPN+ | 16:1 mux, 100 Ω RDS(on), 200 ns tTRANS, ±15 V max - higher on-resistance and slower switching | Lower bandwidth and higher distortion limit use in <100 kSPS data loggers only | Select when cost sensitivity outweighs speed/accuracy needs and MAX part footprint is already validated |
| ADG406BRUZ | 16:1 mux, 70 Ω RDS(on), 150 ns tTRANS, ±15 V - wider temp range (−40 °C to +125 °C) but higher RDS(on) | Preferred for automotive under-hood environments; less suitable for precision medical front-ends | Choose for extended temperature operation where 70 Ω on-resistance and 150 ns delay are acceptable |
Compared with DG406BDW-E3, MAX406CPN+ trades speed and on-resistance for lower cost, while ADG406BRUZ offers extended temperature rating at the expense of higher conduction loss-neither is pin-compatible, requiring layout revision.

FAQ
What is the maximum supply voltage rating for DG406BDW-E3?
The DG406BDW-E3 has an absolute maximum V+ to V− rating of 44 V, enabling safe operation with ±20 V dual supplies or up to +40 V single supply. Exceeding these limits risks permanent damage, and derating applies above 75 °C per datasheet note c. The DG406BDW-E3 must not be operated beyond its specified absolute maximum ratings under any condition.
Does DG406BDW-E3 support single-supply operation?
Yes, DG406BDW-E3 supports single-supply operation from 5 V to 40 V, with analog signal range of 0 V to V+. At V+ = 12 V, typical RDS(on) is 78 Ω and transition time is 130 ns. Logic inputs remain TTL-compatible, and GND serves as the reference-no negative rail required. This makes DG406BDW-E3 suitable for portable and low-voltage embedded systems.
What is the purpose of the EN (enable) pin on DG406BDW-E3?
The EN pin on DG406BDW-E3 controls global switch state: logic low disables all 16 channels (high-impedance off-state), while logic high enables normal address decoding. This allows stacking multiple DG406BDW-E3 devices on a shared D bus and provides power-gating capability to reduce system leakage. EN is TTL-compatible and functions across the full −40 °C to +85 °C temperature range.
How does DG406BDW-E3 prevent channel shorting during address transitions?
DG406BDW-E3 implements break-before-make switching with a minimum tOPEN of 10 ns, ensuring all channels are fully opened before the next channel closes. This eliminates momentary shorting between analog inputs during A0–A3 changes. The behavior is inherent to the internal decoder/driver architecture and requires no external timing control-verified in the truth table and test circuit Fig. 4 of the datasheet.
Is DG406BDW-E3 RoHS-compliant and lead-free?
Yes, the -E3 suffix in DG406BDW-E3 explicitly denotes lead (Pb)-free and RoHS-compliant construction per Vishay documentation E24-0501-Rev. E. The device uses matte tin terminations and complies with EU Directive 2011/65/EU. Material categorization and compliance details are defined in Vishay document 99912, referenced in the datasheet's FEATURES section.
