DG508BEJ-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG508BEJ-E3 is a precision 8-channel single-ended analog multiplexer manufactured by Vishay Siliconix. It connects one of eight inputs to a common output via a 3-bit binary address (A0, A1, A2). Fabricated on an enhanced SG-II CMOS process, it features break-before-make switching and TTL-compatible control inputs. The device supports single or dual power supplies with a maximum rating of 44 V. It operates within an extended temperature range of -40 °C to +125 °C. This specific part number utilizes a 16-lead PDIP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the presence of the E3 suffix indicating lead-free compliance and RoHS standards. Ensure the ordering matches the specified 16-lead PDIP package configuration. Request official datasheets and reliability data from Vishay Siliconix prior to integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel single-ended multiplexer is required in a through-hole format. Verify that the 380 Ohm maximum on-resistance at room temperature meets circuit requirements. Ensure supply voltages remain within the 44 V absolute maximum limit. Consider the 16-lead PDIP footprint constraints during PCB layout design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the DG508B/DG509B family of precision analog multiplexers. The DG508B variant provides single-ended switching, while the DG509B offers dual 4-channel differential switching. Both share the same enhanced CMOS architecture and pinout compatibility, allowing for flexible system design choices based on channel configuration needs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Officially documented superior alternatives include ADG508A, DG508A, and HI-508. These components offer comparable functionality but may require verification of pinout compatibility and electrical parameter alignment before substitution.
