Overview
The DG409DY is a dual 4:1 analog multiplexer manufactured by Harris Corporation, housed in a 16-pin SOIC surface-mount package. It operates on a single supply voltage ranging from 5 V to 30 V or dual supplies up to ±20 V. The device features a maximum on-resistance of 175 Ohms and typical turn-on/turn-off times of 600 ns and 300 ns respectively. Power dissipation is rated at 696 mW, with an operating temperature range spanning -40°C to +85°C.
Feature Summary
- Dual 4:1 multiplexer configuration within a compact 16-lead SOIC package
- CMOS logic compatibility for TTL and CMOS control signals
- Wide single-supply operation capability up to 30 V
Applications
- Data acquisition systems
- Audio switching systems
- Automatic testers
Procurement Notes
Verify the manufacturer designation carefully, as the DG409 part number has been produced by multiple vendors including Maxim Integrated and Vishay. Confirm that the specific DG409DY variant matches the required electrical parameters, particularly regarding on-resistance and switching speeds, before integration into the design.
Selection Notes
Select this component when a dual 4:1 multiplexing function is required in a surface-mount format. Ensure the application signal levels remain within the specified 5 V to 30 V single-supply range. Consider the 175 Ohm on-resistance limit for signal integrity requirements in the target circuit path.
Part Context
This component belongs to the DG409 series of CMOS analog multiplexers originally developed by Harris Semiconductor. The series provides high-performance switching capabilities for various analog signal routing applications. The DG409DY specifically denotes the dual 4:1 configuration in the standard SOIC-16 package style.
Replacement Considerations
The DG409DY+ from Analog Devices/Maxim Integrated serves as a direct functional equivalent. Verify pinout compatibility and check if the replacement's on-resistance and switching speed specifications meet the original design constraints.
