Description

DG408DY is a variant in the DG408 family of CMOS analog switches/multiplexers. It acts as an analog switch array: one of several input channels can be connected to a common output (multiplexing) or the reverse (demultiplexing) under digital control. The device is used to route analog signals in instrumentation, data acquisition, signal processing, audio routing, and test equipment. It uses CMOS technology with typically low on-resistance, low leakage, and a wide supply voltage range, allowing operation from a few volts up to higher rails (exact ranges depend on the variant). The “DY” suffix designates a specific package/quality grade; pinout and packaging vary by supplier. Driving it requires digital select lines (and sometimes an enable line) compatible with TTL/CMOS logic. For precise specifications—channel count, on-resistance, leakage, switching time, break-before-make behavior, and exact supply ranges—consult the manufacturer’s datasheet for the DG408DY.

Equivalent

Please confirm DG408DY’s function and specs. If it’s the DG408 family 4-channel analog switch, typical equivalents include:
- Analog Devices: ADG408/ADG409
- Vishay Siliconix: DG408/DG409 family
- TI: 74HC4066 (quad bilateral switch) or 74HC4053 (triple 2-channel), depending on required channels and voltage
For exact pin‑for‑pin cross‑reference, provide package (DIP/SOIC) and supply voltage.

Features

DG408DY is a CMOS analog switch in the DG408 family. Key features (typical for DG408 devices; check your exact datasheet for the DY variant):
- Transmission-gate/bi-directional analog switch
- Can operate from single or dual power supplies
- Control input compatible with TTL/CMOS levels
- On-resistance in a moderate range; low leakage when off
- Break-before-make switching
- Fast switching (nanoseconds scale)
- Wide analog signal range within supply rails
- Overvoltage/ESD protection and robust I/O protection
- Available in standard packages (e.g., DIP8, SOIC) and common industrial temperature ranges
Note: exact specs (RON, leakage, supply range, temperature range) vary by manufacturer and version. Please consult the specific datasheet for DG408DY to get precise numbers.

Pinout

- Pin count: 8 pins (DIP-8/SO-8)
- Function: CMOS bilateral analog switch (DG408 family). Provides a bidirectional pass element between its input/output terminals, controlled by a digital control input to route or disconnect an analog signal.
