Product details
Overview
DG406EUI-T from Maxim Integrated is a 16-channel single-ended CMOS analog multiplexer with rail-to-rail signal handling, 100Ω max on-resistance, 8Ω max channel-to-channel on-resistance matching, and 15pC max charge injection. It operates from +5V to +30V single supply or ±4.5V to ±20V dual supplies and is used in precision data-acquisition systems requiring low leakage and high channel uniformity.
For engineers reviewing the DG406EUI-T datasheet, DG406EUI-T pinout, DG406EUI-T application, or DG406EUI-T equivalent, key selection criteria include guaranteed on-resistance flatness (9Ω max), input off-leakage <5nA at +85°C, ESD protection >2000V, TTL/CMOS-compatible digital control, and TSSOP-28 packaging for space-constrained industrial instrumentation.
Technical Context
The DG406EUI-T implements a CMOS transmission-gate architecture with bidirectional analog switching capability and break-before-make timing (110–300ns). Its decoder logic accepts four address inputs (A0–A3) plus enable (EN) to select one of 16 source channels (S1–S16) to the common drain (D).
It supports rail-to-rail analog signals up to ±10V with V+ = ±15V, maintains low dynamic power (1.25mW max), and features matched on-resistance across all channels-critical for minimizing gain error in multi-channel sensor front-ends and sample-and-hold circuits.
Key Specifications

| 12 | GND | Ground reference - shared return for digital and analog sections |
| 14–17 | A3–A0 | Binary address inputs - select one of 16 channels via 4-bit code |
| 18 | EN | Enable control - high-active logic input enabling/disabling all switches simultaneously |
| 19–26 | S1–S8 | Analog input channels - first group of eight bidirectional switch terminals |
| 27 | V- | Negative supply input - required for dual-supply operation; tied to GND for single-supply use |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG406BRUZ | 16-channel, 75Ω max on-resistance, -40°C to +85°C, TSSOP-28, but 25pC max charge injection | Higher charge injection limits use in sub-16-bit sample-and-hold; better for general-purpose routing | Select when lower on-resistance is prioritized over ultra-low charge injection |
| MAX4617ESE+ | 8-channel, 60Ω max on-resistance, SOIC-16, 10pC max charge injection, single-supply only (+2.7V to +12V) | Half the channel count and narrower supply range - suitable for compact, low-voltage portable instruments | Select when board space and supply constraints outweigh need for 16 channels |
Compared with ADG406BRUZ and MAX4617ESE+, the DG406EUI-T uniquely balances 16-channel density, 15pC charge injection, and dual-supply flexibility - making it optimal for industrial data-acquisition modules requiring both precision and configurability.

FAQ
What is the maximum analog signal range supported by the DG406EUI-T?
The DG406EUI-T supports rail-to-rail analog signals from V− to V+. With ±15V dual supplies, this yields a ±15V range; with +12V/0V single supply, it supports 0V to +12V. The absolute maximum analog voltage is limited by the supply rails - exceeding V+ or falling below V− risks damage due to internal diode conduction, as specified in the Absolute Maximum Ratings table.
Does the DG406EUI-T require external pull-up resistors on its address or enable pins?
No, the DG406EUI-T does not require external pull-up resistors. Its digital inputs (A0–A3, EN) have CMOS-compatible thresholds (VAL ≤ 0.8V, VAH ≥ 2.4V) and exhibit low input current (±1.0µA max), allowing direct interfacing with microcontrollers and FPGAs. Internal structure ensures stable logic states without external biasing under normal operating conditions.
Can the DG406EUI-T operate with unbalanced supplies like +24V and -5V?
Yes, the DG406EUI-T supports unbalanced supplies such as +24V and -5V, provided the difference between V+ and V− does not exceed +44V and each supply remains within its absolute maximum rating (V+ ≤ 44V above V−, GND referenced appropriately). This flexibility enables use in legacy industrial systems with non-symmetric power rails while maintaining full analog signal range from -5V to +24V.
How is the DG406EUI-T protected against electrostatic discharge?
The DG406EUI-T is tested and guaranteed to withstand >2000V HBM ESD per MIL-STD-883 Method 3015.7. This level of protection is built into the silicon process and layout - no external components are required for basic ESD resilience in controlled assembly environments. For field-replaceable connectors or exposed test points, additional system-level protection (e.g., TVS diodes) is still recommended.
Is the DG406EUI-T pin-compatible with older DG406 variants?
Yes, the DG406EUI-T is explicitly designed as a pin-compatible plug-in upgrade for industry-standard DG406 devices. It shares identical pinout, footprint (TSSOP-28), and electrical interface with legacy versions like DG406DJ+ and DG406CJ+, while delivering improved specifications including tighter on-resistance matching (8Ω vs. older 15Ω typical) and lower charge injection (15pC vs. 25pC).
