Overview
The DG507AAK/B is a dual 8-to-1 analog multiplexer switch manufactured by Rochester Electronics. It features two independent channels, each capable of switching eight input lines to a single output. The device utilizes CMOS technology for low power consumption and high-speed signal routing. It supports TTL and CMOS logic levels for control inputs. The component operates with single or split power supplies, accommodating various voltage ranges. It includes an enable input for system expansion when multiple units are integrated. The package type is TSSOP-28, suitable for surface-mount applications.
Feature Summary
- Dual configuration providing two independent 8:1 multiplexing paths
- CMOS construction ensuring low static power dissipation
- Compatible with standard TTL and CMOS digital logic families
- Integrated enable pin allows cascading multiple devices in complex systems
Applications
- Data acquisition systems requiring multi-channel signal selection
- Medical instrumentation for precise analog signal routing
- Automatic test equipment for switching test points
- Communication systems handling signal distribution
Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical characteristics and packaging variations. Ensure the source provides traceability to Analog Devices specifications as Rochester Electronics manufactures these components under license. Confirm RoHS compliance status through the provided datasheet before integration into regulated assemblies.
Selection Notes
Select this component when a dual 8-channel analog switching solution is required within a compact surface-mount footprint. Consider the on-resistance and charge injection parameters if signal integrity is critical for precision applications. Verify that the supply voltage range matches the system requirements for both logic and analog signals. Evaluate thermal performance based on the expected switching frequency and load conditions.
Part Context
Rochester Electronics specializes in extending the lifecycle of obsolete and hard-to-find semiconductors. They manufacture the DG507 series under licensed agreements from the original designer. This approach ensures availability for long-term industrial and aerospace applications where original production may have ceased. The company maintains rigorous quality standards for these legacy parts.
Replacement Considerations
The DG406 and DG407 are documented as drop-in replacements for the DG506A and DG507A series. These alternatives offer lower on-resistance and faster transition times while maintaining compatible pinouts. Verify electrical parameter compatibility before substituting to ensure system performance remains within design limits.
