Product details
Overview
DG2034DN-T1-E4 from Vishay Siliconix is a power-down fault-protected, 4-channel (4:1) analog multiplexer operating from 1.8 V to 5.5 V with 2.5 Ω typical on-resistance at 5 V, 166 MHz bandwidth, and −67 dB off-isolation at 1 MHz-designed for precision data acquisition and video signal routing in battery-powered instrumentation.
For engineers reviewing the DG2034DN-T1-E4 datasheet, DG2034DN-T1-E4 pinout, DG2034DN-T1-E4 application, or DG2034DN-T1-E4 equivalent, key selection considerations include its break-before-make switching action, −2 pC charge injection, 7 pF source-off capacitance, and QFN12 (3 mm × 3 mm) package compatibility with high-density PCB layouts.
Technical Context
The DG2034DN-T1-E4 implements a CMOS analog switch architecture with three digital address inputs (A0, A1, EN) selecting one of four bidirectional analog inputs (S1–S4) to a common output (COM). Its internal power-down fault protection clamps current when V+ is grounded, preventing damage during system power sequencing.
It features rail-to-rail analog signal handling (0 V to V+), guaranteed 13 ns turn-on time at 5 V, and low 0.6 Ω on-resistance flatness-enabling minimal signal distortion across the full input voltage range in sample-and-hold and multiplexed ADC front-end designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 2.5 Ω at V+ = 5 V - ensures minimal voltage drop and gain error in precision signal paths |
| Bandwidth | 166 MHz - supports high-speed video and wideband analog signal routing without attenuation |
| Off-isolation | −67 dB at 1 MHz - suppresses crosstalk between inactive channels in multi-signal systems |
| Charge injection | −2 pC - reduces settling error and glitch in sample-and-hold and data acquisition circuits |
| Turn-on time | 13 ns at V+ = 5 V - enables fast channel switching for time-critical multiplexing applications |
| Supply range | 1.8 V to 5.5 V - allows direct interfacing with 1.8 V, 3.3 V, and 5 V logic and analog domains |
| ESD rating | 8 kV HBM - enhances robustness against handling and interface-level electrostatic discharge |
Pinout & Package
The DG2034DN-T1-E4 is packaged in a 12-pin QFN (3 mm × 3 mm) with exposed thermal pad, optimized for low-inductance grounding and thermal dissipation in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | S1, S2, S3, S4 | Bidirectional analog inputs - each connects to COM when selected; blocks up to V+ when off |
| 5 | GND | Ground reference for logic and analog sections - must be low-impedance for noise control |
| 6 | EN | Active-high enable - disables all switches when low, enabling power-down fault protection |
| 7, 8 | A0, A1 | Binary address inputs - determine which Sx channel connects to COM per truth table |
| 9 | COM | Common analog output - bidirectional path carrying selected channel's signal |
| 10, 11, 12 | V+, NC, NC | Positive supply (pin 10); pins 11 and 12 are no-connect - reserved for package integrity |
Key Features
| Feature | Design Value |
|---|---|
| Power-down fault protection | Prevents >50 mA fault current when V+ = 0 V - eliminates need for external blocking diodes during hot-swap or brownout |
| Break-before-make switching | Minimum 5 ns tBBM - avoids momentary shorting between channels during address transitions |
| Ultra-low charge injection | −2 pC - limits voltage step on hold capacitors to <2 mV for 1 nF sampling networks |
| Rail-to-rail analog range | 0 V to V+ - supports full-scale signal switching without clipping in single-supply systems |
| Low off-capacitance | 7 pF source-off, 27 pF COM-off - minimizes loading and phase shift on unselected signal paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMUX1308RTER | 8-channel, 1.8 V–5.5 V, 4.5 Ω RDS(on), no power-down fault protection | Lacks fault protection; higher on-resistance increases gain error in precision DC paths | Choose when channel count >4 is required and fault protection is managed externally |
| ADG1414YRUZ | 4-channel, ±15 V dual supply, 1.3 Ω RDS(on), no 1.8 V operation | Requires dual supply; incompatible with single-supply 1.8 V logic interfaces | Choose for high-voltage industrial signal routing where rail-to-rail 1.8 V support is unnecessary |
Compared with TMUX1308RTER and ADG1414YRUZ, the DG2034DN-T1-E4 uniquely combines 1.8 V operability, integrated power-down fault protection, and 2.5 Ω on-resistance in a 3 mm × 3 mm QFN-making it optimal for space-constrained, battery-powered systems requiring robust single-supply analog multiplexing.

FAQ
What is the maximum analog signal voltage supported by the DG2034DN-T1-E4?
The DG2034DN-T1-E4 supports analog signals from 0 V to V+, meaning its maximum analog voltage equals the applied positive supply voltage-up to +5.5 V. This rail-to-rail capability allows full-scale signal switching without clipping in single-supply configurations, and internal clamping diodes limit input overvoltage to V+ + 0.3 V.
Does the DG2034DN-T1-E4 require external pull-up or pull-down resistors on its address pins?
No, the DG2034DN-T1-E4 does not require external biasing on A0, A1, or EN. Its digital inputs have guaranteed VIH of 1.76 V and VIL of 1.3 V at V+ = 5 V, and input leakage remains below 1 μA across temperature-allowing direct connection to standard CMOS logic outputs without additional components.
How does power-down fault protection work in the DG2034DN-T1-E4?
When V+ is driven to 0 V while analog inputs remain active, the DG2034DN-T1-E4 internally disconnects all channels and limits fault current to ≤5 μA (typical) - verified under V+ = 0 V, VS = 5.5 V conditions. This prevents latch-up or damage during hot-swap, brownout, or partial-power-down scenarios without external circuitry.
Can the DG2034DN-T1-E4 be used in bidirectional signal paths?
Yes, the DG2034DN-T1-E4 is fully bidirectional: each switch conducts equally well from Sx to COM or COM to Sx when enabled. Its symmetrical RDS(on) and matched on-resistance flatness (≤1.2 Ω max) ensure consistent performance regardless of signal direction-ideal for shared bus architectures and loop-back diagnostics.
What is the thermal pad connection requirement for the QFN12 package of the DG2034DN-T1-E4?
The exposed thermal pad on the DG2034DN-T1-E4 QFN12 package must be soldered to a solid copper thermal plane on the PCB using ≥60% coverage and standard reflow profile. It is internally connected to GND and serves as both thermal relief and ground reference-leaving it unconnected degrades thermal resistance by >30 °C/W and increases noise susceptibility.
