Product details
Overview
DG408DY-E3 from Vishay Siliconix is an 8-channel single-ended CMOS analog multiplexer that routes one of eight analog inputs to a common output under 3-bit binary address control (A0–A2), with TTL-compatible enable (EN) and break-before-make switching. It delivers 100 Ω on-resistance, 20 pC charge injection, and 160 ns transition time for high-fidelity signal routing in data acquisition and audio systems.
For engineers reviewing the DG408DY-E3 datasheet, DG408DY-E3 pinout, DG408DY-E3 application, or DG408DY-E3 equivalent, key selection criteria include its ±5 V to ±20 V dual-supply or +5 V to +36 V single-supply operation, 44 V absolute max rating, low leakage (<5 nA off-state), and SOIC-16 RoHS-compliant packaging suitable for precision instrumentation and battery-powered designs.
Technical Context
The DG408DY-E3 implements a silicon-gate CMOS architecture with epitaxial latchup protection and rail-to-rail analog signal handling (±15 V typical). Its decoder/driver stage accepts TTL-level logic across –40 °C to +85 °C, enabling direct interface with microcontrollers and FPGAs without level-shifting.
Break-before-make switching prevents momentary crosstalk between adjacent channels, while internal clamping diodes protect against overvoltage transients up to 44 V. The device supports both single- and dual-supply configurations without performance degradation, maintaining consistent RDS(on) matching (≤15 Ω) and off-isolation (–75 dB at 1 MHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog channel count | 8:1 single-ended multiplexer - selects one input from eight to common output |
| On-resistance (RDS(on)) | 100 Ω max at ±15 V - ensures minimal signal attenuation and gain error in precision measurement paths |
| Charge injection | 20 pC - limits voltage glitch on sampled-hold capacitors in ADC front-ends |
| Transition time | 160 ns - enables >1 MHz multiplexed sampling rates in high-speed DAQ systems |
| Supply range | +5 V to +36 V single supply or ±5 V to ±20 V dual supply - supports wide industrial and medical power architectures |
| Off-leakage current | ±5 nA max at full temperature range - preserves accuracy in high-impedance sensor interfaces |

Pinout & Package
Package: 16-pin narrow SOIC (SO-16), JEDEC MS-012 compliant, RoHS-compliant lead (Pb)-free finish (-E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | Analog inputs S1–S8 | Eight bidirectional analog signal terminals - conduct equally in both directions when enabled |
| 9 | Common output D | Single-ended analog output node - connects to selected Sx channel during active state |
| 10 | Enable EN | Active-high TTL-compatible control - forces all switches OFF when low, enabling stacking |
| 11, 12, 13 | Address A0, A1, A2 | 3-bit binary select lines - determine which Sx channel connects to D (000 = S1, 111 = S8) |
| 14 | GND | Logic ground reference - ties digital control circuitry to system ground plane |
| 15 | V− | Negative supply rail - sets lower analog voltage limit; supports dual- or single-supply operation |
| 16 | V+ | Positive supply rail - sets upper analog voltage limit; rated to 44 V absolute max |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal range | Supports signals from V− to V+ - eliminates need for external level-shifting in ±15 V systems |
| Break-before-make switching | Guaranteed tOPEN ≥ 10 ns - prevents short-duration inter-channel crosstalk during address changes |
| TTL-compatible logic inputs | VINH ≥ 2.4 V, VINL ≤ 0.8 V over full temperature range - ensures reliable interfacing with standard logic families |
| Low power consumption | ISUPPLY ≤ 75 μA at full temperature - extends battery life in portable 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+ | 8:1 single-ended, 125 Ω RDS(on), 25 pC charge injection, ±15 V max supply | Higher on-resistance and charge injection; narrower supply range | Preferred where MAXIM's enhanced ESD rating (±2 kV HBM) is required over Vishay's baseline spec |
| ADG1408BRUZ | 8:1 single-ended, 4.7 Ω RDS(on), 23 pC charge injection, ±15 V supply, 12-bit accuracy optimized | Lower on-resistance but higher cost and larger package (TSSOP-16 vs SOIC-16) | Selected when sub-1 Ω RDS(on) matching and <0.01% gain error are critical for 16-bit DAQ |
Compared with DG408DY-E3, MAX4051ACPE+ trades higher on-resistance and charge injection for stronger ESD robustness, while ADG1408BRUZ delivers ultra-low RDS(on) at higher cost and board area-making DG408DY-E3 optimal for cost-sensitive, medium-precision instrumentation requiring proven reliability and SOIC-16 footprint compatibility.

FAQ
What is the maximum supply voltage rating for DG408DY-E3?
The DG408DY-E3 has an absolute maximum voltage rating of 44 V between V+ and V− pins. This allows safe operation with dual supplies up to ±20 V or single supplies up to +36 V, with margin for transient overvoltage events. Operation beyond these limits risks permanent damage, per Vishay's Absolute Maximum Ratings table in Document 70062.
Does DG408DY-E3 support single-supply operation?
Yes, DG408DY-E3 supports true single-supply operation from +5 V to +36 V, with V− tied to GND. In this configuration, the analog signal range extends from 0 V to V+, and all specifications-including RDS(on), charge injection, and leakage-are validated per the "single supply" test conditions in the datasheet (e.g., V+ = 12 V, V− = 0 V).
What is the function of the EN pin on DG408DY-E3?
The EN (enable) pin on DG408DY-E3 is an active-high TTL-compatible control that resets all internal switches to the OFF state when driven low. This feature enables stacking multiple DG408DY-E3 devices on a shared D bus, allowing hierarchical multiplexing without channel contention or crosstalk between units.
How does DG408DY-E3 handle overvoltage conditions on analog inputs?
DG408DY-E3 includes internal clamping diodes that limit analog input voltages to within 2 V of V+ or V−. To prevent forward conduction and excessive current, external series resistors or discrete blocking diodes (e.g., 1N4148) are recommended when inputs may exceed the supply rails-per Application Hint Figure 10 in the DG408/DG409 datasheet.
Is DG408DY-E3 RoHS-compliant and what does the -E3 suffix indicate?
Yes, DG408DY-E3 is RoHS-compliant. The -E3 suffix explicitly denotes lead (Pb)-free terminations and compliance with EU RoHS Directive 2011/65/EU, as confirmed in Vishay's ordering information table and Material Categorization Note in Document 70062. Standard tin/lead finish parts omit the -E3 suffix.
