Vishay DG408DY-T1-E3 Multiplexer, 1 CMOS Single 8:1, Multiplexer, 16-Pin SOIC

Vishay DG408 Series Multiplexer, 8:1 Configuration, 5V Minimum Supply Voltage - DG408DY-T1-E3

This multiplexer is an analogue switching device that selects one of eight inputs to route to a single output, designed for surface mounting. It operates across a wide supply range and is suited to applications requiring CMOS/TTL logic-level compatibility. The device is presented in a small-outline integrated circuit package and is intended for single-element signal routing tasks in electronic systems.

Features and Benefits:

• Single 8:1 switching reduces component count and wiring complexity
  Operates from 5V to 36V allowing high-voltage signal handling
  CMOS logic family input compatibility enables low-power interfacing
  125Ω maximum on-resistance preserves signal integrity under load
  -40 to 85°C operating range supports a wide temperature envelope
  16-pin SOIC package simplifies surface-mount assembly

Applications

• Suitable for multiplexing sensor signals in measurement systems
  Ideal for routing analogue audio or instrumentation lines
  Used with mixed-signal control boards requiring TTL logic levels
  Can be used for selection switching in data-acquisition modules
  Appropriate for compact surface-mount designs with limited space

What physical package should I account for when placing this component?

It comes in a 16-pin SOIC outline with a compact footprint measuring 10mm by 4mm and a profile height of 1.55mm for board layout considerations.

How does the component behave when subjected to elevated supply voltages?

It is rated to function with supply voltages up to 36V, enabling direct handling of higher-voltage analogue signals within that limit.

What thermal range can the device tolerate during operation?

The device is specified to operate from -40°C up to 85°C, allowing use across typical industrial temperature conditions.

How many elements are contained on a single chip and what is their configuration?

The chip contains one switching element configured to provide a single-channel 8-to-1 multiplex function.
