Product details
Overview
DG2034EDN-T1-GE4 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 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 DG2034EDN-T1-GE4 datasheet, DG2034EDN-T1-GE4 pinout, DG2034EDN-T1-GE4 application, or DG2034EDN-T1-GE4 equivalent, key selection criteria 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 DG2034EDN-T1-GE4 implements a CMOS-based 4:1 analog multiplexer controlled by three digital inputs (A0, A1, EN), supporting bidirectional signal flow and full rail-to-rail analog voltage range (0 V to V+). Its internal architecture includes integrated ESD protection diodes and latch-up immunity up to 400 mA.
Power-down fault protection activates when V+ drops to ground, blocking excessive current between Sx and COM terminals. The device maintains consistent performance across −40 °C to +85 °C, with on-resistance flatness ≤1.2 Ω (V+ = 4.5 V) and guaranteed break-before-make timing ≥3 ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 2.5 Ω at V+ = 5 V - enables low insertion loss in signal paths requiring <1 % gain error |
| Bandwidth | 166 MHz - supports composite video and high-speed sensor interface applications |
| Off-isolation | −67 dB at 1 MHz - ensures minimal crosstalk between inactive channels in multi-signal systems |
| Charge injection | −2.6 pC - reduces settling error in sample-and-hold circuits without additional correction |
| Supply voltage range | 1.8 V to 5.5 V - allows direct interfacing with 1.8 V logic and legacy 5 V systems |
| ESD rating | 8 kV HBM - improves robustness against handling-induced transients in automated assembly |
| Switching time | 13 ns turn-on (V+ = 5 V) - meets timing budgets in fast data acquisition with ≤100 MSPS sampling |
Pinout & Package
The DG2034EDN-T1-GE4 is housed in a 12-pin QFN package (3 mm × 3 mm, exposed pad), optimized for thermal dissipation and high-frequency signal integrity. Pin 1 is located at the top-left corner adjacent to the pin #1 marker.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (EN) | Enable input | Active-high logic control: drives all switches OFF when low; overrides address inputs |
| 2 (A0) | Address bit 0 | LSB of 2-bit channel select; used with A1 to determine S1–S4 connection to COM |
| 3 (A1) | Address bit 1 | MSB of 2-bit channel select; decoding follows standard binary truth table |
| 4 (S1) | Channel 1 source | Analog input/output terminal; bidirectional conduction when selected |
| 5 (S2) | Channel 2 source | Analog input/output terminal; electrically identical to S1–S4 in on-state resistance and capacitance |
| 6 (S3) | Channel 3 source | Analog input/output terminal; shares same RDS(on) matching spec (≤0.42 Ω max) |
| 7 (S4) | Channel 4 source | Analog input/output terminal; supports rail-to-rail signal swing up to V+ |
| 8 (COM) | Common output | Single bidirectional analog port; connects to one Sx channel per EN/A1/A0 state |
| 9 (GND) | Ground reference | Return path for logic and analog sections; must be low-impedance for noise suppression |
| 10 (V+) | Positive supply | Single power rail for analog and digital circuitry; powers internal level shifters |
| 11, 12 (NC) | No-connect | Unbonded pins; must remain unconnected per datasheet to avoid parasitic coupling |
Key Features
| Feature | Design Value |
|---|---|
| Power-down fault protection | Prevents >50 mA current flow between Sx/COM when V+ = 0 V - eliminates need for external blocking diodes |
| Ultra-low charge injection | −2.6 pC maximum - minimizes voltage glitch during switching in precision ADC front-ends |
| Bidirectional signal routing | Equal on-resistance in both directions - supports sensor excitation and return path sharing |
| Break-before-make switching | Minimum 3 ns tBBM - prevents momentary shorting between channels during address changes |
| High ESD tolerance | 8 kV HBM - sustains multiple contact discharges without parameter shift or functional failure |

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 | Higher channel count but lacks fault-safe behavior during supply loss | Select when expanding channel density outweighs need for V+ fault tolerance |
| ADG1414YRUZ | 4-channel, ±5 V dual supply, 1.3 Ω RDS(on), 125 MHz bandwidth, no power-down mode | Requires dual supply; superior on-resistance but incompatible with single-supply 1.8 V systems | Select for bipolar signal routing where rail-to-rail swing beyond V+ is required |
Compared with TMUX1308RTER and ADG1414YRUZ, the DG2034EDN-T1-GE4 uniquely combines single-supply 1.8 V operation, power-down fault protection, and 2.5 Ω on-resistance in a 3 mm × 3 mm QFN-making it optimal for space-constrained, battery-operated systems needing fail-safe analog routing.

FAQ
What is the maximum analog signal voltage range supported by the DG2034EDN-T1-GE4?
The DG2034EDN-T1-GE4 supports a full rail-to-rail analog signal range from 0 V to V+, where V+ may be set between 1.8 V and 5.5 V. At V+ = 5 V, signals up to 5 V can pass through any channel without clipping or distortion, provided no terminal exceeds V+ + 0.3 V or falls below −0.3 V relative to GND, as defined in the absolute maximum ratings. This range is confirmed in the "Analog signal range" specification on page 3 of the datasheet.
Does the DG2034EDN-T1-GE4 require external pull-up or pull-down resistors on its digital control lines?
No, the DG2034EDN-T1-GE4 does not require external pull-up or pull-down resistors on A0, A1, or EN. Its digital inputs have leakage current limited to ±1 μA over temperature and specify valid logic thresholds (e.g., VENL ≤ 0.5 V, VENH ≥ 2 V at V+ = 5 V), allowing direct connection to microcontroller GPIOs. Internal design ensures stable state retention without external biasing, as verified in the "Digital Control" section of the specifications table.
How does power-down fault protection function in the DG2034EDN-T1-GE4 during system power loss?
When V+ drops to 0 V, the DG2034EDN-T1-GE4's internal power-down fault protection disables all channel conduction paths, limiting leakage current to ≤5 μA between any Sx pin and COM-even if analog signals remain present at those terminals. This behavior is measured under "Power down leakage" (IPD) in the V+ = 0 V test condition on page 4 of the datasheet and prevents back-driving or damage to upstream sources during brownout or hot-swap events.
Can the DG2034EDN-T1-GE4 be used in bidirectional audio signal routing applications?
Yes, the DG2034EDN-T1-GE4 supports true bidirectional analog signal routing: each channel conducts equally well from Sx to COM or COM to Sx when enabled, with matched on-resistance (<0.42 Ω mismatch) and symmetric capacitance (33 pF COM-on, 7 pF Sx-off). Its −71 dB crosstalk at 1 MHz and low THD characteristics make it suitable for line-level stereo audio switching, as validated in the "Audio and video switching" application note on page 1 of the datasheet.
What is the thermal performance of the DG2034EDN-T1-GE4 in the QFN12 package?
The DG2034EDN-T1-GE4 in the 3 mm × 3 mm QFN12 package has a maximum power dissipation rating of 1295 mW at 25 °C ambient, derating linearly above 70 °C at 16.2 mW/°C. The exposed pad enhances thermal conductivity, enabling junction temperatures to remain within safe limits (<150 °C) under typical 10 mA per channel loads. Thermal data is specified in the "Absolute Maximum Ratings" table on page 2 of the datasheet.
