Overview
The DG529EWN+ is an 8-channel, differential CMOS multiplexer featuring on-board address and control latches. It operates with dual supplies from ±4.5V to ±20V or a single supply from +5V to +30V. The device provides break-before-make switching to prevent momentary shorting of input signals. Electrical specifications include a maximum drain-source on-resistance (rDS(ON)) of 450Ω at TA = TMAX, with a typical value of 270Ω at +25°C. Switching times are typically 1.5µs for turn-on and 1.0µs for turn-off. The component is housed in an 18-pin Wide SO package and supports an operating temperature range of -40°C to +85°C.
Feature Summary
- On-board address and control latches simplify microprocessor-based designs
- Break-before-make switching prevents momentary shorting of input signals
- TTL and CMOS logic compatible digital inputs
Applications
- Data-acquisition systems
- Automatic test equipment
- Avionics and military systems
- Microprocessor-controlled systems
Procurement Notes
Verify the specific suffix EWN corresponds to the 18-pin Wide SO package and the -40°C to +85°C industrial temperature grade. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure power supply rails match the specified operational voltage ranges for reliable performance.
Selection Notes
Select the DG529EWN+ when differential signal routing is required within a latchable multiplexing architecture. This part is suitable for applications needing compatibility with standard TTL and CMOS logic levels across varying supply voltages. Consider the 18-pin Wide SO package constraints for PCB layout and thermal dissipation requirements.
Part Context
This component belongs to the DG528/DG529 family of monolithic CMOS multiplexers. The DG529 variant specifically handles differential signals as a 2-of-8 multiplexer, whereas the DG528 handles single-ended signals. Both share identical pinouts and electrical characteristics, differing primarily in internal channel configuration.
Replacement Considerations
Publicly confirmed substitutes include the DG528EWN+ for single-ended applications and the ADG529EWN+. Verify that replacement parts maintain the same 18-pin Wide SO package and temperature range specifications.
