Product details
Overview
DG9431EDV-T1-GE3 from Vishay Siliconix is a monolithic CMOS SPDT analog switch optimized for precision signal routing in low-voltage instrumentation and healthcare systems. It delivers 17 Ω typical on-resistance at 5 V, 1 pC charge injection, 100 pA max leakage at 25 °C, and operates from +2.7 V to +5.5 V single supply - enabling high-fidelity signal path switching in ADC/DAC front ends and sample-and-hold circuits.
For engineers reviewing the DG9431EDV-T1-GE3 datasheet, DG9431EDV-T1-GE3 pinout, DG9431EDV-T1-GE3 application, or DG9431EDV-T1-GE3 equivalent, key selection criteria include guaranteed break-before-make timing, TSOP-6 package compatibility, low parasitic capacitance (3.8 pF off / 7.8 pF on), and ESD robustness (8 kV HBM).
Technical Context
The DG9431EDV-T1-GE3 implements a single-pole double-throw (SPDT) topology with bidirectional analog conduction and rail-to-rail signal handling up to V+. Its CMOS architecture ensures symmetrical on-resistance across NO and NC paths and guarantees break-before-make operation to prevent signal shorting during state transitions.
Control logic accepts TTL/CMOS-compatible inputs (logic "0" ≤ 0.8 V, logic "1" ≥ 2.4 V) with overvoltage tolerance on the IN pin. Internal protection diodes clamp signals exceeding V+ or GND, and latch-up immunity exceeds 300 mA per JESD78.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUA+ | Higher RDS(on) (35 Ω typ. at 5 V), larger SO-8 package, no TSOP-6 option | Less suitable for space-constrained portable designs; higher on-resistance increases thermal drift in precision gain blocks | Select when SO-8 layout reuse is prioritized over size and leakage performance |
| ADG774BRMZ | Lower charge injection (0.3 pC), but higher leakage (500 pA max), dual SPDT in MSOP-10 | Acceptable for moderate-precision applications where dual-channel integration offsets higher leakage impact | Choose when dual-switch integration justifies trade-off in leakage-sensitive medical front ends |
Compared with MAX4617EUA+ and ADG774BRMZ, the DG9431EDV-T1-GE3 uniquely balances ultra-low charge injection, sub-100 pA leakage, and TSOP-6 compactness - making it optimal for miniaturized, high-accuracy analog signal routing where board space and signal integrity are co-constrained.

FAQ
What is the maximum analog signal voltage range supported by the DG9431EDV-T1-GE3?
The DG9431EDV-T1-GE3 supports a full rail-to-rail analog signal range from 0 V to V+, with absolute maximum ratings allowing signals up to V+ + 0.3 V due to internal clamping diodes. At V+ = 5 V, the usable analog range is 0 V to 5 V; at V+ = 3 V, it is 0 V to 3 V. Exceeding V+ + 0.3 V risks forward-biasing protection diodes and violating absolute maximum limits.
Does the DG9431EDV-T1-GE3 require dual-supply operation?
No, the DG9431EDV-T1-GE3 is designed exclusively for single-supply operation from +2.7 V to +5.5 V. It does not support dual-supply (±V) configurations. Its CMOS architecture and internal level-shifting enable full analog signal swing relative to GND without negative rails, simplifying power design in portable and low-voltage systems.
Is the DG9431EDV-T1-GE3 pin-compatible with other Vishay SPDT switches in TSOP-6?
Yes, the DG9431EDV-T1-GE3 shares identical TSOP-6 pinout and footprint with Vishay's DG9432E (dual SPDT) and DG9433E (SPST) variants. Pin assignments for V+, GND, IN, COM, NO, and NC are consistent across this family, enabling layout reuse and simplified BOM rationalization in multi-function analog interface designs.
What is the guaranteed break-before-make interval for the DG9431EDV-T1-GE3?
The DG9431EDV-T1-GE3 guarantees a minimum break-before-make interval of 3 ns and a maximum of 22 ns at 25 °C with V+ = 5 V. This timing ensures complete isolation between NO and NC paths before the alternate path closes, preventing momentary shorts that could corrupt sensitive analog measurements or damage downstream circuitry.
Can the DG9431EDV-T1-GE3 operate reliably at –40 °C?
Yes, the DG9431EDV-T1-GE3 is fully specified and tested over the industrial temperature range of –40 °C to +85 °C (D suffix). Key parameters including RDS(on), leakage, and switching times retain guaranteed limits across this range, making it suitable for outdoor instrumentation, automotive diagnostics, and cold-environment medical devices.
