Product details
Overview
DG406BDJ from Vishay Siliconix is a 16-channel single-ended CMOS analog multiplexer that routes one of sixteen analog inputs to a common output under 4-bit binary address control. It features 45 Ω on-resistance, 11 pC charge injection, and ±20 V dual-supply operation, enabling high-accuracy signal routing in data acquisition systems with break-before-make switching to prevent input shorting.
For engineers reviewing the DG406BDJ datasheet, DG406BDJ pinout, DG406BDJ application, or DG406BDJ equivalent, this device is selected for precision analog switching where low distortion, rail-to-rail signal handling, and TTL-compatible control across –40 °C to +85 °C are required.
Technical Context
The DG406BDJ integrates silicon-gate CMOS process technology with an epitaxial layer to prevent latchup and supports both dual (±5 V to ±20 V) and single (5 V to 40 V) supply configurations. Its decoder/driver architecture ensures simultaneous address decoding and level shifting for robust logic interface.
Break-before-make timing (min. 10 ns, typ. 39 ns) isolates channels during switching, while off-isolation of –86 dB at 1 MHz and 6 pF source-off capacitance minimize crosstalk in multi-channel instrumentation systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog configuration | 16:1 single-ended multiplexer - selects one of 16 inputs to shared output |
| On-resistance (RDS(on)) | 45 Ω typical at ±15 V - enables <1 LSB error in 12-bit systems with 1 kΩ source impedance |
| Charge injection | 11 pC - limits voltage glitch to <1 mV on 10 nF sampling capacitor |
| Supply range | ±5 V to ±20 V dual or 5 V to 40 V single - supports industrial and battery-powered rails |
| Transition time | 115 ns typical - allows >5 MHz channel update rate in high-speed DAQ |
| Off-isolation | –86 dB at 1 MHz - suppresses inter-channel interference in dense analog routing |
| Enable function | Active-high EN pin - resets all switches to OFF state for cascading or power-safe initialization |
Pinout & Package
DG406BDJ is packaged in a 28-pin wide-body SOIC (SO-28W), measuring 15.4 mm × 7.6 mm × 2.3 mm, with gull-wing leads and standard JEDEC MO-118 outline.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8, 10, 11, 12, 13, 14, 15, 16, 17 | S1–S16 | 16 analog input terminals - bidirectional, rail-to-rail capable, each blocks ±20 V in OFF state |
| 9 | D | Common analog output terminal - connects to selected Sx channel when enabled |
| 18 | V+ | Positive supply rail - supports up to +20 V (dual) or +40 V (single) |
| 19 | V− | Negative supply rail - supports down to –20 V (dual); tied to GND for single-supply use |
| 20 | GND | Analog/digital reference ground - must be low-impedance return path for leakage and switching currents |
| 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 - high = decode active; low = all switches OFF (high-impedance isolation) |
| 26, 27, 28 | NC | No-connect pins - left unconnected per datasheet; no internal connection or function |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal range | Supports signals from V− to V+ - preserves full dynamic range in ±15 V systems without clipping |
| Break-before-make switching | Guaranteed minimum 10 ns open interval - eliminates momentary shorts between adjacent inputs during address changes |
| TTL-compatible control inputs | Valid over full –40 °C to +85 °C range - eliminates need for level shifters in microcontroller interfacing |
| Latchup immunity | Epitaxial CMOS process - withstands I/O overvoltage events without destructive latchup |
| Low power consumption | 23 μA typical positive supply current - enables <0.2 mW static power in battery-operated medical sensors |
Applications
| Data Acquisition Systems | Medical Instrumentation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4051ACPE+ | 8-channel, 100 Ω RDS(on), ±15 V max - higher on-resistance, half channel count | Lower channel density and higher on-resistance limit use in precision 12-bit+ DAQ | Select only if 8-channel count suffices and system tolerates >2× on-resistance variation |
| ADG406BRZ | 16-channel, 70 Ω RDS(on), ±15 V max - higher on-resistance, same package | Higher on-resistance increases gain error in buffered sensor interfaces | Prefer DG406BDJ when <50 Ω on-resistance and ±20 V operation are required for extended range |
Compared with MAX4051ACPE+ and ADG406BRZ, DG406BDJ delivers lower on-resistance (45 Ω vs. 70–100 Ω), wider supply range (±20 V vs. ±15 V), and superior off-isolation (–86 dB), making it optimal for high-fidelity, wide-dynamic-range analog multiplexing where channel count and precision are critical.

FAQ
What is the maximum supply voltage rating for DG406BDJ?
DG406BDJ has an absolute maximum V+ to V− rating of 44 V, allowing operation with ±20 V dual supplies or up to 40 V single supply. Exceeding these limits risks permanent damage. The device is specified for reliable operation from ±5 V to ±20 V dual or 5 V to 40 V single, with guaranteed performance across –40 °C to +85 °C.
Does DG406BDJ support single-supply operation?
Yes, DG406BDJ supports true single-supply operation from 5 V to 40 V. When used with V− tied to GND, it maintains rail-to-rail analog signal handling (0 V to V+), TTL-compatible logic thresholds, and full functionality including break-before-make switching and enable control - verified per datasheet Section 5 specifications.
What is the purpose of the NC pins on DG406BDJ?
DG406BDJ has three NC (no-connect) pins: pins 26, 27, and 28. These pins have no internal connection and must remain unconnected in PCB layout. They serve mechanical or packaging purposes only and carry no electrical function - confirmed in the Functional Block Diagram and Pin Configuration section of Vishay document 72552.
How does the EN pin affect DG406BDJ channel behavior?
When EN is low, all 16 analog switches in DG406BDJ are forced OFF regardless of A0–A3 address state, placing S1–S16 and D in high-impedance isolation. This enables safe stacking of multiple DG406BDJ devices on a shared D bus or power-down sequencing - a feature explicitly documented in the Truth Table and Applications section of the datasheet.
Is DG406BDJ RoHS-compliant?
Yes, DG406BDJ is RoHS-compliant and lead (Pb)-free, indicated by the "-E3" suffix in its ordering code (e.g., DG406BDW-E3). Vishay confirms compliance per EU Directive 2011/65/EU and provides material declarations in document 72552, with full exemption status detailed in www.vishay.com/doc?99912.
