Analog Switches - Special Purpose Procurement Notes

This component is officially listed as discontinued by the manufacturer. Availability is restricted to existing stock or surplus channels. Verify RoHS compliance status through official datasheets before procurement. Confirm package integrity and pin compatibility during sourcing due to end-of-life status.

Analog Switches - Special Purpose Selection Notes

Select this part for legacy designs requiring a single-channel multiplexer in a through-hole DIP-28 package. Ensure supply voltages remain within the 10 V to 18 V range. Consider the 90 Ohm on-resistance limit for signal path accuracy. Verify thermal management capabilities given the 625 mW power dissipation rating in enclosed environments.

Analog Switches - Special Purpose Part Context

The DG538ADJ-E3 belongs to the DG series of analog switches and multiplexers produced by Vishay Siliconix. It serves as a specific variant within the broader multiplexer switch IC category, distinguished by its single-channel architecture and PDIP-28 packaging. This model represents a specialized solution for applications requiring robust analog signal routing in industrial or test equipment contexts.

Analog Switches - Special Purpose Replacement Considerations

Official documentation recommends the DG40 as an alternative. Verify pinout compatibility and electrical specifications against the DG40 datasheet before substitution. No other public substitute part numbers are confirmed.
