DG409DY-T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG409DY-T is a dual differential analog multiplexer switch IC manufactured by Renesas Electronics Corporation. It features two independent 4:1 multiplexing channels housed in a 16-pin SOIC-Narrow surface-mount package. The device supports single supply voltages ranging from 5 V to 36 V and dual supplies from ±5 V to ±20 V. Key electrical specifications include a maximum on-resistance of 100 Ohms, a typical charge injection of 20 pC, and a maximum leakage current of 500 pA. Switching performance is characterized by a maximum turn-on time of 180 ns and a turn-off time of 120 ns, with a propagation delay of 250 ns. The component operates within an industrial temperature range of -40°C to +85°C.
