Product details
Overview
DG9431DV-T1-E3 from Vishay Siliconix is a low-voltage single-pole/double-throw (SPDT) CMOS analog switch in TSOP-6 package, rated for 2.7 V to 12 V supply, with 20 Ω typical rDS(on) at 5 V, 35 ns turn-on time, and 1 pC charge injection - deployed in battery-powered portable test equipment and sample-and-hold circuits.
For engineers reviewing the DG9431DV-T1-E3 datasheet, DG9431DV-T1-E3 pinout, DG9431DV-T1-E3 application, or DG9431DV-T1-E3 equivalent, key selection criteria include guaranteed break-before-make timing, ±20 mA continuous current rating, RoHS-compliant matte tin terminations, and TSOP-6 footprint compatibility with space-constrained PCB layouts.
Technical Context
The DG9431DV-T1-E3 implements a monolithic CMOS SPDT switch fabricated on Vishay's BCD-15 process, supporting bidirectional analog signal routing with rail-to-rail voltage handling up to V+ and guaranteed break-before-make operation. Its logic interface accepts TTL/CMOS-compatible inputs (0.8 V low, 2.4 V high) and exhibits no latchup due to epitaxial isolation.
It delivers stable analog performance across –40 °C to +85 °C, with rDS(on) flatness of 2 Ω (typ) over 1–3 V COM voltage range at 5 V supply, and off-isolation of –74 dB at 1 MHz - enabling precision signal switching in low-noise measurement paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 12 V - supports direct integration into 3.3 V and 5 V systems without level-shifting. |
| rDS(on) (V+ = 5 V) | 20 Ω typ - minimizes signal attenuation and distortion in audio and sensor signal paths. |
| tON / tOFF | 35 ns / 20 ns - enables high-speed multiplexing in data acquisition and communication front-ends. |
| Charge Injection | 1 pC - ensures sub-LSB error in 12-bit+ sample-and-hold and ADC input conditioning. |
| ICOM(on) Max | 200 pA - preserves accuracy in high-impedance sensor interfaces and precision instrumentation. |
| ESD Rating | >2000 V HBM (Method 3015.7) - reduces need for external ESD protection in handheld devices. |
| Package | TSOP-6 - 1.5 mm × 3.0 mm footprint saves board space vs. SOIC-8 in portable designs. |
Pinout & Package
TSOP-6 package: 1.5 mm × 3.0 mm body, 0.95 mm height, 0.65 mm pitch, lead-free matte tin terminations per RoHS.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Digital control input | Accepts TTL/CMOS logic; drives internal switch matrix; low-level ≤0.8 V turns NO path ON. |
| 2 (NO) | Normally open analog terminal | Connects to COM only when IN = logic high; bidirectional, rail-to-rail capable. |
| 3 (COM) | Common analog terminal | Shared I/O node; routes signal to NO or NC based on IN state; handles ±20 mA continuous. |
| 4 (GND) | Analog/digital ground reference | Single ground pin shared by analog and digital sections; requires low-impedance PCB return path. |
| 5 (NC) | No-connect terminal | Internally unconnected; must remain floating - not to be tied to GND or V+. |
| 6 (V+) | Positive supply rail | Powers analog switch core and logic interface; decoupling capacitor required within 1 cm. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make guarantee | Eliminates signal shorting during state transition - critical for protecting downstream amplifiers and ADCs. |
| Low 1 pC charge injection | Reduces settling error and droop in sample-and-hold circuits without requiring additional correction circuitry. |
| 20 Ω rDS(on) matching (ΔrDS(on) ≤ 2 Ω) | Ensures consistent gain and phase response when used in differential or dual-path signal routing. |
| –74 dB off-isolation at 1 MHz | Suppresses crosstalk between channels in multi-signal monitoring systems operating up to RF frequencies. |
| TSOP-6 footprint | Enables compact layout in space-constrained applications like medical wearables and handheld analyzers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUT+T | SO-6 package, 35 Ω rDS(on) at 5 V, 45 ns tON, no guaranteed break-before-make | Higher on-resistance increases THD in audio paths; lacks BbM assurance for critical hold-capacitor isolation | Select when SO-6 footprint is mandatory and BbM is not required; verify leakage specs for high-Z sensor use. |
| ADG849YKSZ-REEL7 | SC-70-6 package, 0.5 Ω rDS(on), 15 ns tON, but only rated to 5.5 V max supply | Superior speed and on-resistance, but incompatible with 12 V systems or industrial 5 V rails with ripple | Prefer for ultra-low-distortion, high-speed applications below 5.5 V; avoid where V+ may exceed 5.5 V. |
Compared with MAX4617EUT+T and ADG849YKSZ-REEL7, the DG9431DV-T1-E3 uniquely balances 20 Ω rDS(on), guaranteed break-before-make, 12 V supply tolerance, and TSOP-6 size - making it optimal for portable test gear and battery-powered instrumentation requiring reliability and space efficiency.

FAQ
What is the maximum supply voltage rating for the DG9431DV-T1-E3?
The DG9431DV-T1-E3 supports a maximum supply voltage of +13 V (absolute maximum rating), with recommended operational range from 2.7 V to 12 V. Operation above 12 V is not advised for sustained use, as electrical parameters such as rDS(on) and leakage are specified only up to 12 V in the datasheet. The device's internal protection diodes clamp signals exceeding V+, but continuous overvoltage risks reliability degradation.
Does the DG9431DV-T1-E3 have guaranteed break-before-make timing?
Yes, the DG9431DV-T1-E3 guarantees break-before-make operation per its datasheet functional description and truth table. This behavior is ensured by internal design and verified across temperature and voltage ranges. It prevents momentary shorting between NO and NC paths during switching - essential for protecting sensitive downstream circuitry like ADC inputs or amplifier stages in the DG9431DV-T1-E3 application.
What is the thermal derating specification for the DG9431DV-T1-E3?
The DG9431DV-T1-E3 has a thermal derating coefficient of 6.5 mW/°C above +75 °C ambient, as specified in the Absolute Maximum Ratings table. At +85 °C, the allowable power dissipation drops to approximately 335 mW from the 400 mW rating at +75 °C. This applies to both TSOP-6 and SOIC-8 packages and must be accounted for in high-density PCB layouts where the DG9431DV-T1-E3 operates near temperature limits.
Is the DG9431DV-T1-E3 compatible with 3.3 V logic control signals?
Yes, the DG9431DV-T1-E3 is fully compatible with 3.3 V logic control signals. Its input threshold is defined as logic low ≤ 0.8 V and logic high ≥ 2.4 V, which aligns with standard 3.3 V CMOS/TTL levels. No level-shifter is needed when driven directly from 3.3 V microcontrollers or FPGAs - a key advantage confirmed in the DG9431DV-T1-E3 datasheet truth table and functional block diagram.
What does the "-E3" suffix indicate in DG9431DV-T1-E3?
The "-E3" suffix in DG9431DV-T1-E3 denotes 100 % matte tin device terminations and full RoHS compliance, as explicitly stated in the Vishay datasheet. It replaces lead-containing terminations and meets exemption requirements for Pb-free manufacturing. This suffix distinguishes the environmentally compliant version from non-RoHS variants and is critical for export-controlled and consumer electronics applications requiring DG9431DV-T1-E3 traceability and regulatory documentation.
