DG641DY-T1

Analog Switches, Multiplexers, Demultiplexers Overview

The DG641DY-T1-E3 is a video switch integrated circuit manufactured by Vishay / Siliconix, featuring a configuration of four single-pole single-throw (SPST) switches. It operates on a single supply voltage ranging from 10 V to 21 V, with a typical operating voltage of 15 V and a maximum switch voltage of 8 V. The device delivers a bandwidth of 500 MHz, with a maximum turn-on time of 70 ns and a maximum turn-off time of 50 ns. The maximum on-resistance is 15 Ohms, and the typical off-isolation is -60 dB. Power dissipation is rated at 600 mW. It functions within an operating temperature range of -40°C to +85°C and is housed in a surface-mount SOIC-16 package.
