Product details
Overview
DG408DQ-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 precision data acquisition and audio routing in ±15 V or +12 V single-supply systems.
For engineers reviewing the DG408DQ-E3 datasheet, DG408DQ-E3 pinout, DG408DQ-E3 application, or DG408DQ-E3 equivalent, key selection criteria include guaranteed 44 V absolute max supply rating, -40 °C to +85 °C operating range, TSSOP-16 RoHS-compliant packaging, and verified performance in battery-powered instrumentation where low 10 μA supply current and rail-to-rail signal blocking are critical.
Technical Context
The DG408DQ-E3 implements a silicon-gate CMOS architecture with epitaxial latchup protection, supporting both dual-supply (±5 V to ±20 V) and single-supply (5 V to 36 V) operation. Its decoder/driver stage ensures TTL logic compatibility across the full temperature range, while break-before-make timing prevents crosstalk during channel transitions.
Each channel conducts bidirectionally with matched RDS(on) ≤ 125 Ω and off-state leakage ≤ ±5 nA at full temperature range. Internal clamping diodes protect against overvoltage transients up to 44 V, and the enable function resets all switches to off for cascading multiple devices without signal contention.
Key Specifications

| Analog signal range | ±15 V with ±15 V supplies - maintains full rail-to-rail input/output capability without clipping |
| Enable turn-on/off time | 115 ns / 105 ns typical - allows tight synchronization with external control logic in ATE applications |
| Off isolation | -75 dB at 1 MHz - suppresses crosstalk between inactive channels in multi-sensor monitoring |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4051ACSE+ | 8-channel, 100 Ω RDS(on), but only ±5.5 V max supply; no 44 V rating or single-supply operation above 12 V | Suitable for low-voltage mixed-signal systems only; not viable for ±15 V industrial or medical front-ends | Select DG408DQ-E3 when 44 V absolute max rating, rail-to-rail analog range, or single-supply operation up to 36 V is required. |
| ADG1408BRUZ | 8-channel, 4.7 Ω RDS(on), but higher 35 pC charge injection and 1.2 mA supply current; requires ±15 V or +12 V only | Better for low-RON precision applications where power budget allows; unsuitable for ultra-low-power battery operation | Choose DG408DQ-E3 for sub-100 μA supply current and proven 20 pC charge injection in portable instrumentation. |
Compared with MAX4051ACSE+ and ADG1408BRUZ, the DG408DQ-E3 uniquely balances 44 V ruggedness, 10 μA quiescent current, and 20 pC charge injection-making it optimal for battery-powered medical devices and industrial data loggers requiring wide supply flexibility and low glitch energy.

FAQ
What is the maximum supply voltage rating for the DG408DQ-E3?
The DG408DQ-E3 has an absolute maximum V+ to V− rating of 44 V, with dual-supply operation supported from ±5 V to ±20 V and single-supply operation from +5 V to +36 V. This 44 V rating is enabled by Vishay's 44 V silicon-gate CMOS process and allows safe operation in high-voltage industrial and medical systems where transient overvoltages may occur. The DG408DQ-E3 maintains full functionality and parameter guarantees within these ranges.
Does the DG408DQ-E3 support single-supply operation, and what is its minimum single-supply voltage?
Yes, the DG408DQ-E3 supports true single-supply operation from +5 V to +36 V. At +12 V single supply, it delivers 90 Ω typical RDS(on), 180 ns transition time, and 5 pC charge injection - confirming robust performance without dual rails. This capability simplifies power architecture in portable devices like handheld analyzers and battery-powered sensors, eliminating the need for negative supplies while preserving analog signal integrity across the full input range.
What is the purpose of the EN (enable) pin on the DG408DQ-E3, and how does it behave?
EN is an active-high TTL-compatible enable input that forces all eight analog switches into the off state when driven low (≤0.8 V). When high (≥2.4 V), normal address decoding resumes. This feature allows stacking multiple DG408DQ-E3 devices on a shared D bus without contention, and enables system-level power gating. The DG408DQ-E3 specifies 115 ns typical enable turn-on time and 105 ns turn-off time - ensuring precise timing control in synchronized ATE and data acquisition systems.
How does the DG408DQ-E3 prevent crosstalk between channels during switching?
The DG408DQ-E3 uses break-before-make switching with a guaranteed minimum tOPEN of 10 ns, ensuring no overlap between the turn-off of one channel and turn-on of the next. This eliminates momentary shorting between adjacent analog inputs - a critical requirement in high-accuracy multiplexed systems such as medical sensor arrays and precision thermocouple scanners. The DG408DQ-E3 also achieves −75 dB off-isolation at 1 MHz, further suppressing capacitive coupling between inactive and active channels.
Is the DG408DQ-E3 RoHS-compliant, and what does the "-E3" suffix indicate?
Yes, the DG408DQ-E3 is RoHS-compliant and lead (Pb)-free, as confirmed by the "-E3" suffix per Vishay's ordering nomenclature. This designation indicates compliance with EU Directive 2011/65/EU and related global environmental regulations. The device is manufactured in Vishay's qualified TSSOP-16 assembly sites and carries full material declarations per Vishay document 99912. No exemptions or Pb-containing finishes are used in the DG408DQ-E3.
