Product details
Overview
DG406DW 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 operation. It routes one of sixteen analog inputs to a common output under 4-bit binary address control and features break-before-make switching for input protection in data acquisition front ends.
For engineers reviewing the DG406DW datasheet, DG406DW pinout, DG406DW application, or DG406DW equivalent, this device is selected for high-accuracy, low-glitch signal routing in battery-powered instrumentation where rail-to-rail analog range, low power (0.2 mW), and latchup immunity are critical design requirements.
Technical Context
The DG406DW implements a silicon-gate CMOS architecture with epitaxial layer isolation to prevent latchup and supports both ±5 V to ±20 V dual supplies and +12 V single supply. Its decoder/driver block interprets A0–A3 and EN inputs to select exactly one of 16 Sx channels to connect to the D output terminal.
Break-before-make timing (min. 10 ns, typ. 50 ns) ensures no momentary shorting between channels during switching, while the 200 ns transition time and −69 dB off-isolation at 100 kHz enable clean signal separation in multi-channel sampling systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog channels | 16 single-ended inputs to 1 common output - enables compact front-end multiplexing without external buffering |
| On-resistance (RDS(on)) | 50 Ω max. at ±15 V - minimizes gain error and settling time in precision ADC driver stages |
| Charge injection | 15 pC typ. - reduces voltage glitch on sampled-hold capacitors, critical for 12-bit+ accuracy |
| Supply voltage range | ±5 V to ±20 V dual; +12 V single - supports industrial, medical, and avionics rails without level-shifting |
| Transition time | 200 ns typ., 450 ns max. - defines minimum channel dwell time for 694 kHz aggregate sampling rate (16 ch) |
| Off-isolation | −69 dB at 100 kHz - suppresses crosstalk between active and inactive channels in dense signal routing |
| Leakage current | ±0.5 nA max. off-state - preserves signal integrity in high-impedance sensor interfaces (e.g., thermocouples) |
Pinout & Package
DG406DW is packaged in a 28-pin wide-body SOIC (SO-28W) with 0.300-inch body width and standard 1.27 mm pitch. Pin 1 is marked by a beveled corner or notch; pin numbering follows counterclockwise convention from top-left.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply rail | Bias for internal logic and switch PMOS transistors; must be ≥ |V−| for full analog range |
| V− | Negative supply rail | Bias for NMOS switches; sets lower bound of analog signal range (e.g., −15 V) |
| GND | Ground reference | Logic ground and substrate reference; separate from analog signal ground in mixed-signal layouts |
| D | Common output | Single-ended analog output node; connects to ADC input or amplifier inverting input |
| S1–S16 | Analog inputs | 16 bidirectional analog terminals; conduct equally well in either direction when enabled |
| A0–A3 | Binary address inputs | TTL-compatible digital inputs selecting channel (0–15); A0 = LSB, A3 = MSB |
| EN | Enable control | Active-high logic input; forces all switches OFF when low, enabling cascaded multiplexer stacks |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guarantees ≥10 ns gap between channel disconnect and next connect - prevents input shorting in stacked configurations |
| 44 V absolute max. rating | Withstands transient overvoltage up to ±22 V on V+/V− - enhances robustness in noisy industrial environments |
| Latchup immunity | Epitaxial CMOS process eliminates parasitic SCR conduction - allows safe operation beyond supply rails |
| TTL-compatible inputs | Valid logic levels defined at 0.8 V (low) and 2.4 V (high) across −40 °C to +85 °C - simplifies interface to microcontrollers |
| Low power dissipation | 0.2 mW typical quiescent power - extends battery life in portable medical and test equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX306CWI+ | 16:1 single-ended, 100 Ω RDS(on), ±15 V max., 25 pC charge injection | Higher on-resistance and charge injection reduce DC accuracy and increase settling time vs. DG406DW | Select for legacy MAXIM-based designs where footprint compatibility exists but accept 2× higher gain error |
| ADG1606BRUZ | 16:1 single-ended, 4.5 Ω RDS(on), ±16.5 V max., 0.6 pC charge injection, SPI interface | Lower RDS(on) and charge injection improve precision, but SPI control adds firmware overhead vs. parallel address | Choose when ultra-low distortion and sub-16-bit accuracy are required and microcontroller SPI resources are available |
Compared with MAX306CWI+, DG406DW delivers 2× lower on-resistance and 60 % less charge injection for improved DC accuracy; versus ADG1606BRUZ, it offers simpler parallel addressing but trades off 10× higher RDS(on) and 25× higher charge injection for cost-sensitive, low-complexity designs.

FAQ
What is the maximum analog signal voltage range supported by the DG406DW?
The DG406DW supports analog signals from V− to V+, with absolute maximum supply ratings of ±22 V. When operated at ±15 V supplies, the guaranteed analog signal range is −15 V to +15 V. At +12 V single supply (V− = GND), the range is 0 V to 12 V. Signals exceeding V+ or V− are clamped by internal diodes, limiting forward current to 20 mA per terminal.
Does the DG406DW require external pull-up resistors on its address or enable pins?
No, the DG406DW does not require external pull-up resistors. Its A0–A3 and EN inputs are TTL-compatible with guaranteed logic thresholds of ≤0.8 V for low and ≥2.4 V for high across the full −40 °C to +85 °C temperature range. Input currents remain within ±1 μA, allowing direct connection to microcontroller GPIOs or FPGA outputs without additional biasing.
Can the DG406DW be used in a single-supply configuration with V− tied to ground?
Yes, the DG406DW supports true single-supply operation with V− = GND and V+ = +12 V. In this mode, the analog signal range is 0 V to 12 V, RDS(on) increases to 90–120 Ω (vs. 50 Ω bipolar), and dynamic parameters such as tTRANS and charge injection remain within specified limits. The enable and address inputs retain full TTL compatibility.
How does the break-before-make interval affect system-level timing in a multiplexed data acquisition setup?
The DG406DW guarantees a minimum break-before-make interval of 10 ns (typ. 50 ns), ensuring no overlap between channel disconnect and reconnect. This prevents momentary shorts during address transitions, eliminating signal corruption in cascaded or paralleled multiplexer configurations. System designers must account for this interval plus tTRANS (200 ns typ.) when calculating minimum channel dwell time for accurate settling.
Is the DG406DW RoHS-compliant and lead-free?
Yes, the DG406DW-T1-E3 variant is RoHS-compliant and lead-free, as indicated by the "-E3" suffix per Vishay's ordering nomenclature. It meets EU RoHS Directive 2011/65/EU and is manufactured using lead-free terminations and halogen-free molding compounds. Full compliance documentation is available in Vishay's material declaration portal under document 70061.
