Overview
The DG408DY-T1-E3 is an 8-channel single-ended analog multiplexer produced by Vishay Siliconix. This component is designed to connect one of eight inputs to a common output, making it highly versatile for various signal switching and routing applications. The DG408 series is known for its high performance, low power dissipation, and robust switching characteristics, which include break-before-make switching action to prevent crosstalk between channels. The device is controlled by a 3-bit binary address (A0, A1, A2) and features an enable (EN) function that allows all switches to be turned off, which is useful for stacking multiple devices. All control inputs are TTL compatible over the full specified operating temperature range of -40°C to 85°C.
