Product details
Overview
DG406BDW-T1-E3 from Vishay Siliconix is a 16-channel single-ended CMOS analog multiplexer with TTL-compatible control inputs, 45 Ω on-resistance, 115 ns transition time, and ±20 V dual-supply operation. It routes one of sixteen analog inputs to a common output under 4-bit binary address control and supports break-before-make switching for signal integrity in data acquisition systems.
For engineers reviewing the DG406BDW-T1-E3 datasheet, DG406BDW-T1-E3 pinout, DG406BDW-T1-E3 application, or DG406BDW-T1-E3 equivalent, this device is selected for high-accuracy, low-glitch analog signal routing in battery-powered instrumentation, medical equipment, and ATE where wide supply range and low charge injection (11 pC) are critical.
Technical Context
The DG406BDW-T1-E3 integrates silicon-gate CMOS process technology enabling 44 V absolute maximum rating and latchup immunity via epitaxial layer. Its decoder/driver architecture supports parallel-addressed channel selection with EN-controlled global disable for cascading multiple devices.
Break-before-make timing (min. 10 ns, typ. 39 ns) prevents input shorting during channel transitions. All analog channels conduct bidirectionally with rail-to-rail blocking capability up to ±20 V supplies, and digital inputs meet TTL thresholds (VINL ≤ 0.8 V, VINH ≥ 2.4 V) across –40 °C to +85 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel count | 16:1 single-ended analog multiplexer - selects one input from sixteen to common output |
| On-resistance (RDS(on)) | 45 Ω typical at ±15 V - ensures minimal signal attenuation and gain error in precision measurement paths |
| Transition time (tTRANS) | 115 ns typical - enables sampling rates up to ~4 MHz in high-speed data acquisition |
| Charge injection (Q) | 11 pC - reduces voltage glitch on sampled-hold capacitors, critical for ADC front-end accuracy |
| Analog signal range | ±15 V (dual supply), 0–12 V (single supply) - supports industrial and medical sensor interfaces |
| Supply voltage range | ±5 V to ±20 V dual; 5 V to 40 V single - accommodates legacy ±15 V systems and modern low-voltage designs |
| Enable turn-on/off time | tON(EN) = 75 ns, tOFF(EN) = 50 ns - allows fast system-level power gating without signal disruption |
Pinout & Package
Package: 28-pin wide-body SOIC (SO-28W), 15.88 mm × 7.62 mm body size, 1.27 mm pitch, RoHS-compliant lead (Pb)-free finish (-E3).

| 9 | Ground (GND) | Reference node for logic inputs and internal level shifters - must be connected to system ground |
| 18, 19, 20, 21 | Address inputs A0–A3 | 4-bit binary select lines - determine active channel (0–15); TTL-compatible over full temperature range |
| 22 | Enable (EN) | Active-high global enable - forces all switches OFF when low, enabling stacking and power sequencing |
| 23 | Drain (D) | Common analog output terminal - carries selected channel's signal bidirectionally |
| 24, 25 | Power supplies V+, V− | Positive/negative supply rails - support ±20 V operation; clamp diodes protect against overvoltage |
| 26, 27, 28 | No-connect (NC) | Unbonded pins - must remain unconnected per datasheet; no internal function or electrical path |
Key Features
| Feature | Design Value |
|---|---|
| Low on-resistance matching | ΔRDS(on) ≤ 5% - minimizes channel-to-channel gain mismatch in multi-sensor scanning |
| Rail-to-rail analog blocking | Off-state isolation up to ±20 V - prevents signal bleed between unselected channels in high-voltage systems |
| Break-before-make switching | Min. 10 ns open interval - eliminates momentary shorts during address changes, protecting sensitive sources |
| Low leakage current | IS(off), ID(off) ≤ ±5 nA max - preserves accuracy in high-impedance sensor and electrophysiology circuits |
| Single-supply compatibility | Operates from 5 V to 40 V - simplifies power design in portable and industrial equipment without bipolar rails |

FAQ
What is the maximum supply voltage rating for DG406BDW-T1-E3?
The DG406BDW-T1-E3 has an absolute maximum rating of 44 V between V+ and V−, allowing safe operation with ±20 V dual supplies or up to 40 V single supply. Exceeding these limits risks permanent damage, and operation above ±20 V requires verification of internal clamping diode current limits per datasheet Note a.
Does DG406BDW-T1-E3 support single-supply operation?
Yes, DG406BDW-T1-E3 supports single-supply operation from 5 V to 40 V. At V+ = 12 V and V− = GND, it maintains analog signal range of 0–12 V and on-resistance of 78 Ω typical, enabling use in portable and industrial systems without negative rails.
What is the purpose of the NC pins on DG406BDW-T1-E3?
Pins 26, 27, and 28 on DG406BDW-T1-E3 are no-connect (NC) terminals - they are physically present but electrically unconnected to any internal circuitry. Per Vishay documentation, these pins must remain unconnected on PCB layout to avoid unintended coupling or mechanical stress.
How does the break-before-make feature work in DG406BDW-T1-E3?
The DG406BDW-T1-E3 guarantees a minimum 10 ns break interval (tOPEN) between deactivation of one channel and activation of the next, preventing momentary shorts during address transitions. This is implemented in the internal decoder/driver and verified across –40 °C to +85 °C per datasheet Figure 4 test circuit.
Is DG406BDW-T1-E3 RoHS-compliant?
Yes, DG406BDW-T1-E3 is RoHS-compliant and lead (Pb)-free, as indicated by the "-E3" suffix per Vishay ordering information. It meets EU Directive 2011/65/EU requirements and is documented in Vishay's material categorization table (www.vishay.com/doc?99912).
