Overview
The DG429DW is a high-speed, low distortion CMOS analog multiplexer manufactured by Vishay Siliconix. It features four independent single-pole single-throw (SPST) switches housed in an SOIC-16 surface-mount package. The device operates with a single supply voltage ranging from +4.5V to +36V or dual supplies of ±5V to ±18V. Key electrical specifications include a maximum on-resistance of 100 ohms and a typical channel-to-channel isolation of -75 dB at DC. The component supports a continuous current of 30 mA per switch and dissipates up to 600 mW of power.
Feature Summary
- Four independent SPST analog switches integrated into a single compact package
- Low on-resistance for minimal signal attenuation across the operating range
- High channel-to-channel isolation to prevent crosstalk between signals
- Compatible with standard digital logic families including TTL and CMOS
Applications
- Data acquisition systems requiring multi-channel signal routing
- Industrial process control instrumentation
- Audio signal switching and matrix routing
- Medical equipment signal conditioning
Procurement Notes
Verify the specific suffix 'DW' corresponds to the SOIC-16 narrow body package when sourcing. Confirm RoHS compliance status through official manufacturer documentation as environmental declarations may vary by production batch. Ensure the ordering part number matches the exact pin configuration required for the target PCB layout.
Selection Notes
Select this component when designing circuits that require four isolated analog paths within a limited board area. Consider the 100-ohm on-resistance limit against the source impedance of the application. Verify that the input signal levels remain within the specified supply voltage boundaries to prevent latch-up or damage to the internal protection structures.
Part Context
This part belongs to the DG4xx series of analog switches produced by Vishay Siliconix. The series is characterized by its use of CMOS technology to achieve low power consumption and high speed. The DG429DW specifically addresses applications needing multiple independent channels without the complexity of external discrete switching components.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided reference material. Engineers should consult the official Vishay datasheet for recommended alternatives or cross-reference with similar quad SPST multiplexers from other manufacturers based on pin compatibility and electrical parameters.
