DG417LDY-T1

Overview

The DG417LDY-T1 is a single-channel SPST analog switch IC manufactured by Vishay Siliconix. It operates within a dual supply voltage range of ±15 V and supports single supply configurations. The device features a maximum on-resistance of 18.5 Ohms, with a typical switching time of 41 ns and an off-time of 32 ns. Power dissipation is rated at 400 mW, while the maximum supply current is 1 uA. The component handles a DC switch current of 30 mA and functions reliably across an operating temperature range from -40°C to +85°C. It is housed in an SOIC-8 surface-mount package.

Feature Summary

Single-pole single-throw (SPST) configuration for precise signal routing
Low power consumption suitable for battery-operated systems
High-speed switching capabilities for data acquisition applications

Applications

Data acquisition systems requiring signal multiplexing
Instrumentation circuits needing low leakage isolation
Communication equipment for line termination or selection

Procurement Notes
