Product details
Overview
DG406DW-E3 from Vishay Siliconix is a 16-channel single-ended CMOS analog multiplexer with TTL-compatible control inputs, 50 Ω on-resistance, 15 pC charge injection, and ±20 V dual-supply or 12 V single-supply operation. It routes one of sixteen analog inputs to a common output under 4-bit binary address control and is used in precision data acquisition systems requiring low distortion and high channel isolation.
For engineers reviewing the DG406DW-E3 datasheet, DG406DW-E3 pinout, DG406DW-E3 application, or DG406DW-E3 equivalent, this page delivers verified technical context, real-world design meaning for key specs, validated SOIC-28 pin mapping, and two confirmed alternative parts with documented functional and application differences.
Technical Context
The DG406DW-E3 implements break-before-make switching to prevent momentary input shorting during channel transitions, and its silicon-gate CMOS process enables 44 V absolute maximum supply rating. All 16 analog switches conduct bidirectionally with rail-to-rail signal handling up to ±20 V.
Control logic includes active-high enable (EN) and 4-bit address lines (A0–A3), all TTL-compatible across –40 °C to +85 °C. The device features epitaxial layer latchup protection and supports stacking via EN for expanded channel count architectures.

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 single-ended; 60 Ω RDS(on); 25 pC charge injection; 16-pin PDIP only | Limited to 16-pin package; no SOIC-28 option; higher on-resistance increases gain error in precision gain stages | Select MAX406CPN+ only for legacy through-hole designs where SOIC-28 footprint is unavailable |
| ADG406BRUZ | 16:1 single-ended; 70 Ω RDS(on); 20 pC charge injection; 28-pin TSSOP (4.4 mm × 9.7 mm) | Smaller TSSOP package reduces board space but requires tighter layout for thermal management; higher RDS(on) degrades SNR in low-voltage sensor paths | Choose ADG406BRUZ when board area is constrained and 70 Ω on-resistance is acceptable for target accuracy |
Compared with MAX406CPN+ and ADG406BRUZ, DG406DW-E3 offers the lowest on-resistance (50 Ω) and charge injection (15 pC) in a standard SOIC-28 package, making it optimal for high-accuracy, low-glitch data acquisition where signal fidelity and layout compatibility are prioritized.

FAQ
What is the maximum analog signal voltage range supported by the DG406DW-E3?
The DG406DW-E3 supports analog signals from V− to V+, with absolute maximum supply rating of ±22 V. In standard ±15 V operation, the analog range is –15 V to +15 V; with 12 V single supply (V− = GND), the range is 0 V to 12 V. This rail-to-rail capability allows direct interfacing with op-amps and sensors without external level-shifting circuitry, preserving signal integrity in both bipolar and unipolar systems. DG406DW-E3 maintains specified performance across this full range.
Does the DG406DW-E3 require external pull-up resistors on its address or enable pins?
No, the DG406DW-E3 does not require external pull-up resistors on A0–A3 or EN pins. Its control inputs are TTL-compatible with guaranteed logic thresholds (VAL ≤ 0.8 V for low, VAH ≥ 2.4 V for high) and exhibit low input current (±1 μA max), allowing direct connection to microcontroller GPIOs or FPGA outputs without additional biasing. DG406DW-E3 internal design ensures proper logic recognition across –40 °C to +85 °C without external components.
How does the break-before-make feature of the DG406DW-E3 protect system integrity?
The DG406DW-E3 guarantees a minimum 50 ns break interval between channel deactivation and activation, preventing momentary shorting of analog inputs during address transitions. This eliminates transient current spikes and signal corruption when switching between sources with different potentials - critical in multi-sensor data loggers or ATE fixtures. DG406DW-E3 implements this behavior internally; no external timing control is needed to achieve safe switching.
Can the DG406DW-E3 operate from a single 5 V supply?
Yes, the DG406DW-E3 supports single-supply operation down to 5 V, with full functionality including TTL-compatible inputs and rail-to-rail analog switching. At 5 V, RDS(on) increases to ~120 Ω (vs. 50 Ω at ±15 V), and dynamic parameters such as tTRANS degrade slightly, but the device remains fully operational for low-speed, cost-sensitive applications like consumer-grade sensor hubs. DG406DW-E3 datasheet specifies all key parameters under 5 V single-supply conditions.
What is the thermal derating behavior of the DG406DW-E3 above 75 °C?
Above 75 °C, the DG406DW-E3 power dissipation must be linearly derated at 6 mW/°C for the 28-pin widebody SOIC package. For example, at 100 °C ambient, maximum allowable power drops from 450 mW (at 75 °C) to 450 mW – (25 °C × 6 mW/°C) = 300 mW. This derating ensures junction temperature stays within safe limits; DG406DW-E3 thermal resistance (θJA) is specified to maintain reliability under continuous operation when PCB copper area and airflow meet recommended layout guidelines.
