DG412DY-T1-E3 

The Vishay DG412DY-T1-E3 is a monolithic quad analog switch IC from the DG411 series, engineered for efficient switching of precision analog signals. It combines low power consumption (0.35 μW) with high-speed performance (110 ns turn-on time), making it suitable for portable and battery-powered industrial and military applications.

Key features include a maximum supply rating of 44V and an analog signal range of ±15V. The on-resistance is typically 25 Ω for the DG411 variant and up to 80 Ω for the DG412. It operates across a temperature range of -40°C to +85°C and is compatible with TTL and CMOS logic levels.

Built using Vishay Siliconix’s high-voltage silicon gate process, this series prevents latch-up through an epitaxial layer. Each switch conducts equally well in both directions when on and blocks input voltages up to the supply levels when off. The DG411 and DG412 respond to opposite control logic, while the DG413 features two normally open and two normally closed switches.

Applications include precision automatic test equipment, data acquisition systems, communication systems, battery-powered devices, and computer peripherals. The DG412DY-T1-E3 is supplied in a surface-mount (SMD/SMT) package, typically on a reel with a factory pack quantity of 2500.
