Overview
The DG508ABK is a monolithic CMOS analog multiplexer featuring an 8-channel (1-of-8) configuration. It operates from dual power supplies ranging from ±4.5V to ±18V and guarantees latch-up immunity even when power supplies are off while input signals remain present. The device ensures break-before-make switching, logic and enable inputs compatible with TTL and CMOS standards, and low power consumption suitable for portable equipment.
Feature Summary
- Monolithic CMOS design with guaranteed latch-up protection
- Break-before-make switching capability
- TTL and CMOS-compatible address and enable inputs
Applications
- Data acquisition systems
- Signal routing
- Control systems
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature range. Confirm RoHS compliance status as standard CERDIP packages may differ from lead-free variants. Cross-reference the part number with current distributor listings to ensure availability and authenticity before procurement.
Selection Notes
Select this component for applications requiring an 8-channel analog multiplexer with robust latch-up protection and low power consumption. Ensure the operating environment falls within the -20°C to +85°C temperature range specified for the ABK variant. Verify that the required supply voltage aligns with the ±4.5V to ±18V operational limits.
Part Context
The DG508ABK belongs to the DG508A/DG509A series of monolithic CMOS analog multiplexers manufactured by Maxim Integrated, now part of Analog Devices Inc.
