DG508BEN-T1-GE4

Analog Switches, Multiplexers, Demultiplexers Overview

The DG508BEN-T1-GE4 is an 8-channel single-ended analog multiplexer from the Vishay Siliconix DG508B/DG509B series. 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 operates with single or dual power supplies ranging from ±5 V to ±20 V, or up to 44 V absolute maximum rating. It is housed in a 16-lead miniQFN package (1.8 mm x 2.6 mm) and supports an extended operating temperature range of -40 °C to +125 °C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Enhanced SG-II CMOS process for reduced charge injection and lower leakage
• Break-before-make switching action prevents momentary crosstalk between adjacent channels
• TTL-compatible digital control inputs across the full specified temperature range
• Epitaxial layer provides latch-up protection

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the package type and temperature range. The 'EN' suffix indicates the miniQFN-16 package, while 'E3' denotes lead-free compliance. Ensure that the selected variant matches the required thermal and mechanical specifications for the target application before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel single-ended multiplexing function is required within the DG508B family. Compare performance metrics such as on-resistance and bandwidth against alternative packages like SOIC or TSSOP if space constraints differ. Confirm that the miniQFN package dimensions align with the PCB layout requirements and that the thermal dissipation characteristics are suitable for the intended operating environment.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG508B/DG509B precision analog multiplexer family. The DG508B variant specifically provides 8:1 single-ended switching, whereas the DG509B offers dual 4:1 differential switching. Both share similar fabrication processes and electrical characteristics but differ in channel configuration and pinout assignments for address and enable lines.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Officially documented superior alternatives include ADG508A, DG508A, and HI-508. Verify pin compatibility and electrical parameter alignment before substituting these parts.
