概述

Description

DG408DY is an 8-channel CMOS analog switch/multiplexer. It lets you connect one of eight analog inputs to a common output (or route a common input to one of eight outputs) under control of three select lines. It provides high-impedance paths for non-selected channels and a low, defined on-resistance for the selected path. Typical uses include signal routing in data acquisition, instrumentation, sensor multiplexing, and test equipment. Key features usually include break-before-make switching, a wide supply range, and low leakage. The “DY” suffix denotes a specific packaging/variant of the device (temperature/lead form). For exact electrical specs (on-resistance, leakage, bandwidth), timing diagrams, pinout, and rail requirements, consult the official datasheet from the manufacturer.

Features

DG408DY is a CMOS analog switch (DG408 family) used as an 8-channel analog switch/multiplexer/demultiplexer. Typical features (common to DG408-type parts):
- CMOS bilateral analog switch with multiple pass channels
- Wide supply range (single or dual supply; supports rail-to-rail signaling in many ranges)
- Low on-resistance and low leakage when off
- High off-isolation and good signal integrity
- Fast switching with low charge injection
- Control inputs compatible with TTL/CMOS logic levels
- Low quiescent power
- Available in compact packages; DY suffix commonly indicates a specific package (e.g., DIP-8 or related)
Note: exact parameters (R_on, leakage, bandwidth, control voltage ranges, and package options) vary by vendor and exact DG408DY revision. For precise figures, consult the datasheet for the specific manufacturer/year.

Package

DG408DY is in a 16‑pin plastic DIP package (DIP-16).

Pinout

- Pin count: 8 (DIP-8/SO-8 package)
- Function: DG408DY is an SPDT analog switch (single-pole double-throw) used to route an analog signal between two terminals under a control input.

Manufacturer

Manufacturer: Vishay Intertechnology (Siliconix brand).
What kind of company: A global semiconductor company that designs and manufactures discrete semiconductors, integrated circuits, and passive components for the electronics industry.

Application
