Product details
Overview
DG406BDN-T1 from Vishay Siliconix is a 16-channel single-ended CMOS analog multiplexer with break-before-make switching, 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 TTL-compatible logic across –40 °C to +85 °C for high-speed data acquisition and medical instrumentation.
For engineers reviewing the DG406BDN-T1 datasheet, DG406BDN-T1 pinout, DG406BDN-T1 application, or DG406BDN-T1 equivalent, this device delivers low charge injection (11 pC), high off-isolation (–86 dB), and robust ±44 V absolute maximum rating-critical for precision signal routing in battery-powered and avionics systems where rail-to-rail analog range and latchup immunity are required.
Technical Context
The DG406BDN-T1 uses a silicon-gate CMOS process with epitaxial layer protection against latchup and operates with single (5–40 V) or dual (±5 V to ±20 V) supplies. Its decoder/driver architecture implements break-before-make switching to prevent input shorting during channel transitions.
All 16 switch channels conduct bidirectionally with matched RDS(on) (ΔRDS(on) ≤ 5 %), and the EN pin resets all switches to off-state-enabling stacking of multiple devices in large-scale multiplexed systems without signal contention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog configuration | 16:1 single-ended multiplexer - selects one of 16 inputs to shared output |
| On-resistance | 45 Ω typical at ±15 V - ensures minimal signal attenuation and gain error in precision measurement paths |
| Transition time | 115 ns typical - enables >5 MHz channel switching rates in high-throughput data acquisition |
| Charge injection | 11 pC - reduces voltage glitch on sampled-hold nodes, critical for ADC front-end accuracy |
| Off-isolation | –86 dB at 1 MHz - suppresses crosstalk between inactive channels in dense analog routing |
| Supply range | ±5 V to ±20 V dual or 5–40 V single - supports industrial, medical, and avionics rails without level-shifting |
| Leakage current | ±5 nA max at full temperature range - preserves signal integrity in high-impedance sensor interfaces |
Pinout & Package
DG406BDN-T1 is packaged in a 28-pin PLCC (Plastic Leaded Chip Carrier) with 11.43 mm × 11.43 mm body, 1.27 mm lead pitch, and exposed thermal pad-compatible footprint per Vishay Doc. 71264. Pin 1 is marked by corner notch; package is RoHS-compliant (-E3 suffix implied by -T1 tape-and-reel ordering code).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply rail | Bias for internal logic and switch PMOS transistors; supports up to +20 V in dual-supply mode |
| V- | Negative supply rail | Bias for internal logic and switch NMOS transistors; supports down to –20 V in dual-supply mode |
| GND | Ground reference | Logic ground and substrate reference; must be connected even in single-supply operation |
| D | Common output | Drain node shared by all 16 switches; bidirectional signal path with rail-to-rail analog swing |
| S1–S16 | Analog inputs | Source terminals of individual switches; each conducts equally well in either direction |
| A0–A3 | Binary address inputs | 4-bit parallel select lines; TTL-compatible (0.8 V / 2.4 V thresholds) across full temperature range |
| EN | Enable control | Active-high global enable; forces all switches open when low, enabling multi-device stacking |
| NC | No-connect | Pins 4, 12, 13, 25 - internally unconnected; must remain floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX406CPN+ | 16:1 mux, 100 Ω RDS(on), 200 ns tTRANS, ±15 V max - higher on-resistance and slower switching | Lower bandwidth and higher distortion in precision DC-coupled paths | Acceptable for lower-speed industrial monitoring where cost is prioritized over settling time |
| ADG406BRUZ | 16:1 mux, 70 Ω RDS(on), 150 ns tTRANS, ±20 V - wider temp range (–40 °C to +125 °C) but higher leakage (±20 nA) | Higher off-leakage limits use in ultra-high-impedance pH or ion-selective electrodes | Preferred for automotive under-hood applications requiring extended temperature tolerance |
Compared with MAX406CPN+ and ADG406BRUZ, the DG406BDN-T1 offers the lowest on-resistance and fastest transition time within its voltage class, making it optimal for high-fidelity, high-throughput analog signal routing where minimal gain error and rapid channel settling are design-critical.

FAQ
What is the maximum supply voltage rating for DG406BDN-T1?
The DG406BDN-T1 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. This extended rating is enabled by Vishay's 44 V silicon-gate CMOS process and provides margin against transients in industrial and avionics environments. Operation beyond these limits risks permanent damage.
Does DG406BDN-T1 support single-supply operation?
Yes, DG406BDN-T1 supports single-supply operation from 5 V to 40 V. In this mode, V− is tied to ground, and the analog input/output range extends from 0 V to V+, enabling simplified power architecture in portable and embedded systems. The device maintains TTL-compatible logic thresholds and specified RDS(on) performance across the full single-supply range.
What is the function of the EN pin on DG406BDN-T1?
The EN (enable) pin on DG406BDN-T1 is an active-high control that globally disables all 16 switches when driven low. When EN = 0 V, all channels are forced open regardless of address inputs-preventing unintended conduction and enabling cascading or stacking of multiple DG406BDN-T1 devices in large-scale multiplexing architectures without signal contention.
How does DG406BDN-T1 achieve latchup immunity?
DG406BDN-T1 achieves latchup immunity through an epitaxial layer structure integrated into its 44 V silicon-gate CMOS process. This construction prevents parasitic SCR formation under overvoltage, ESD, or high-current stress conditions-ensuring robust operation in noisy industrial and avionics environments without requiring external protection circuitry.
Is DG406BDN-T1 RoHS-compliant?
Yes, DG406BDN-T1 is RoHS-compliant. The "-T1" suffix denotes tape-and-reel packaging, and per Vishay's ordering information, DG406BDN-T1-E3 is the RoHS-compliant variant. Standard production of DG406BDN-T1 meets EU Directive 2011/65/EU requirements, with lead-free terminations and compliant manufacturing processes verified per Vishay Doc. 99912.
