Overview
The DG429DW-E3 is a CMOS analog multiplexer switch manufactured by Vishay Siliconix, housed in a 16-SOIC surface-mount package. It integrates two independent 4-to-1 multiplexer circuits, providing four channels per switch with latch-up performance exceeding 1000 V per JEDEC standard JESD78. The device operates on dual supplies ranging from ±5 V to ±20 V or single supplies up to 36 V. Key electrical specifications include a maximum on-resistance of 150 Ohms, a typical on-resistance match of 10 Ohms, and propagation delays of 250 ns for turn-on and 280 ns for turn-off. It supports a continuous DC switch current of 30 mA and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates two independent 4:1 multiplexer switches in a compact 16-pin SOIC package.
- Features high reliability with latch-up performance exceeding 1000 V according to JEDEC standards.
- Supports flexible power configurations including dual supplies (±5V to ±20V) and single supplies up to 36V.
- Provides low charge injection and consistent on-resistance matching for signal integrity.
Applications
- Data acquisition systems requiring multi-channel signal routing.
- Industrial process control instrumentation.
- Medical equipment signal conditioning.
- Automotive test and measurement applications.
Procurement Notes
Verify the specific suffix DW against the official Vishay datasheet to confirm the 16-SOIC package variant. Confirm RoHS compliance status via the manufacturer's latest documentation. Check for obsolescence notices as this component series may have discontinuation updates. Ensure design-in approval aligns with current supply chain availability.
Selection Notes
Select the DG429DW-E3 when dual 4:1 multiplexing is required in a small surface-mount footprint. Compare on-resistance and leakage current requirements against lower-power alternatives like the DG411 if speed is not critical. Verify that the 150 Ohm max Ron fits the application's voltage drop constraints. Consider thermal dissipation limits in dense PCB layouts.
Part Context
This component belongs to the DG4xx series of CMOS analog switches and multiplexers from Vishay Siliconix. The series is known for high-speed operation and robust latch-up protection. The DG429 specifically offers dual multiplexer functionality, distinguishing it from single-switch variants like the DG409 or SPST switches like the DG411.
Replacement Considerations
Potential substitutes include the ADG429 from Analog Devices or the MAX429 from Maxim Integrated. Verify pin compatibility and electrical parameter equivalence before substitution. Check for updated packaging options or lead-free variants from alternative manufacturers.
