Overview
The DG508ABY is a monolithic CMOS analog multiplexer manufactured by Harris Corporation. It features a single 8:1 channel configuration housed in a 16-lead CERDIP package. The device operates on dual supplies ranging from ±4.5V to ±18V or a single supply of 4.5V to 18V. Key electrical specifications include a maximum on-resistance of 400 ohms, an on-resistance matching of 24 ohms, and a leakage current of 500pA. Transition times are specified at 1µs for turn-on and 700ns for turn-off. It supports an operating temperature range from -55°C to +125°C.
Feature Summary
- CMOS technology ensures low power consumption and high input impedance.
- Monolithic construction provides reliable signal switching with minimal distortion.
- CERDIP packaging offers durability for harsh environment applications.
Applications
- Data acquisition systems
- Precision instrumentation
- Demultiplexing circuits
Procurement Notes
Verify the specific suffix 'ABY' against official Harris or successor manufacturer datasheets to confirm pinout and electrical tolerances. Check component status as legacy parts may be discontinued or available only through secondary markets. Ensure environmental compliance matches project requirements.
Selection Notes
Select this component when an 8-channel analog switch with ceramic DIP packaging is required. Compare on-resistance and leakage specs against system signal integrity needs. Verify that the ±18V supply capability aligns with the target application voltage rails.
Part Context
The DG508 series belongs to a family of CMOS analog multiplexers originally produced by Harris Corporation, later acquired by Maxim Integrated and subsequently Analog Devices. The DG508 variant specifically provides eight inputs to one output, distinguishing it from the DG506 (dual 4:1) and DG509 (dual 4:1 differential) models.
Replacement Considerations
Publicly confirmed substitute part numbers for the DG508ABY were not identified in the provided source material. Consult distributor cross-reference lists for potential equivalents such as the MPC508AP if availability is critical.
