DG529EWN

Analog Switches, Multiplexers, Demultiplexers Overview

The DG529EWN is an 8-channel, differential CMOS multiplexer featuring on-board address and control latches. It operates with dual supplies ranging 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 the temperature extremes, with a typical value of 270Ω at +25°C. The unit supports a maximum analog signal range of ±15V under standard conditions and maintains TTL and CMOS logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix EWN to confirm the wide SOIC-18 package and industrial temperature range (-40°C to +85°C). Ensure that the design accommodates the required power supply voltages for the intended analog signal range. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG529EWN when differential signal switching is required within a latchable multiplexer architecture. This part is suitable for applications needing break-before-make timing to avoid signal overlap. Verify that the system power supply falls within the specified single or dual voltage ranges to ensure proper logic threshold operation and on-resistance characteristics.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG529EWN belongs to the Maxim Integrated DG528/DG529 family of monolithic CMOS multiplexers. While the DG528 handles single-ended signals, the DG529 variant manages differential pairs. The EWN suffix specifically denotes the industrial temperature grade and the 18-pin Wide Small-Outline package, distinguishing it from commercial grades or alternative packaging options like DIP or CERDIP.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG529EWN is pin and electrically compatible with the industry-standard DG529 and the Analog Devices ADG529. When substituting, verify that the replacement component matches the specific temperature range and package dimensions required by the existing board layout.
