Overview
The DG507ACWI+ is a monolithic CMOS analog multiplexer featuring an 8-channel differential (2 of 16) configuration housed in a 28-pin Wide SO package. It operates with supply voltages ranging from ±4.5V to ±18V and supports symmetrical, bidirectional signal routing. The device incorporates break-before-make switching logic and TTL/CMOS compatible address inputs. Electrical specifications include a maximum on-resistance of 450Ω at ±15V supplies, off-isolation of 68dB at 500kHz, and low power consumption suitable for portable applications.
Feature Summary
- Monolithic CMOS design ensuring latch-up immunity during power-off conditions
- Break-before-make switching prevents signal shorting between channels
- Bidirectional operation with symmetrical performance characteristics
- TTL and CMOS compatible logic and enable input interfaces
Applications
- Data acquisition systems
- Signal routing networks
- Aircraft heads up displays
- Control systems
- Data logging systems
Procurement Notes
Verify the specific suffix 'ACWI+' against official manufacturer documentation to confirm lead-free/RoHS compliance status and wide SOIC packaging. Confirm that the component meets the required temperature range of 0°C to +70°C. Ensure the ordering specification matches the exact pinout and electrical tolerances defined in the current datasheet revision.
Selection Notes
Select this component when a differential 8-channel multiplexing solution is required within a single integrated circuit. Verify that the application voltage requirements fall within the ±4.5V to ±18V operational range. Consider the 28-pin Wide SO package dimensions for PCB layout compatibility. Evaluate the 450Ω maximum on-resistance against the system's signal integrity requirements.
Part Context
The DG507A belongs to the DG506A/DG507A series of monolithic CMOS analog multiplexers manufactured by Analog Devices Inc./Maxim Integrated. This series provides high-density signal switching capabilities. The DG507A specifically addresses differential channel requirements, offering two sets of eight bidirectional channels controlled by a common address bus and enable signal.
Replacement Considerations
Publicly documented drop-in replacements include Harris HI507, Siliconix DG507A, and Intersil IH6216. These components share pin compatibility and meet or exceed the original specifications.
