Overview
The DG407DY is a monolithic CMOS analog multiplexer manufactured by Renesas Electronics. It features two independent 8:1 multiplexing channels within a single 28-pin SOIC package. The device operates on a single supply voltage ranging from 5V to 34V or dual supplies up to ±20V. Key electrical specifications include a maximum on-resistance of 100Ω, a transition time of 300ns, and charge injection of 40pC. It supports TTL and CMOS logic levels and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Monolithic CMOS construction with integrated digital decode circuitry for channel selection
- Dual 8:1 multiplexer configuration providing sixteen bilateral analog switches
- Low power consumption design suitable for battery-operated systems
- Reduced charge injection simplifies sample and hold applications
Applications
- Data acquisition systems
- Medical instrumentation
- Automatic test equipment
- Communication systems
Procurement Notes
Verify the specific suffix 'DY' corresponds to the 28-lead plastic small outline package (SOIC) variant. Confirm RoHS compliance status as older manufacturing runs may differ from current production standards. Ensure the source document explicitly lists the DG407DY part number to avoid confusion with other package options like DIP or TSSOP.
Selection Notes
Select this component when a dual 8:1 multiplexer is required with low on-resistance and fast switching speeds. It serves as a drop-in replacement for legacy DG506A/DG507A series devices. Consider the 100Ω on-resistance limit and 300ns transition time against system signal integrity requirements.
Part Context
The DG407 belongs to the DG406/407 family of high-voltage CMOS analog multiplexers. These devices utilize a silicon-gate process to achieve improved performance over previous generations. The family includes variants with different pin counts and configurations, such as the DG406 which offers a 16-channel single-ended option.
Replacement Considerations
Public confirmed substitute part numbers include ADG407BNZ from Analog Devices Inc. and DG407CJ+ from Maxim Integrated. Verify pinout compatibility and electrical parameter alignment before substitution.
