Overview
The DG428DN is an 8-channel multiplexer switch IC manufactured by Vishay Siliconix, housed in a 20-PLCC surface-mount package. It operates with a single supply voltage up to 12 V or dual supplies of ±15 V. The device features a maximum on-resistance of 100 Ohms and supports channel-to-channel matching of 5 Ohms. Switching times are limited to 150 ns for both turn-on and turn-off periods, with a propagation delay of 250 ns. Power dissipation reaches 800 mW, while leakage current remains below 500 pA. The component functions within a temperature range of -40°C to +85°C.
Feature Summary
- Provides eight independent signal paths within a single integrated circuit
- Supports both single and dual power supply configurations for flexible system integration
- Ensures signal integrity through low charge injection and tight channel-to-channel resistance matching
Applications
- Data acquisition systems requiring multi-channel signal routing
- Industrial control circuits utilizing analog switching
- Test and measurement equipment needing precise signal selection
Procurement Notes
Verify the specific suffix requirements for the ordered part number against official datasheets to ensure correct packaging and RoHS compliance status. Confirm availability as this component may be discontinued or subject to production changes. Cross-reference manufacturer part numbers with distributor listings to validate authenticity and sourcing channels before procurement.
Selection Notes
Select this component when an eight-channel multiplexer is required in a surface-mount PLCC package. Ensure the application voltage does not exceed 12 V for single supply or ±15 V for dual supply operation. Verify that the 100 Ohm on-resistance meets the signal path requirements and that the operating temperature range aligns with environmental conditions.
Part Context
This device belongs to the DG4xx series of analog switches and multiplexers from Vishay Siliconix. It serves as a compact solution for routing multiple analog signals in space-constrained designs. The PLCC package offers a balance between pin count and board area efficiency compared to larger DIP alternatives.
Replacement Considerations
Public confirmed substitute part numbers include DG419BDY-T1-E3 and ADG428BPZ. Verify electrical compatibility and pinout alignment before substitution.
