DG541DY-T1

Analog Switches - Special Purpose Overview

The DG541DY-T1-E3 is a wideband video switch IC manufactured by Vishay Siliconix, housed in a 16-pin Narrow SOIC package. It features four independent SPST channels with bidirectional signal paths. The device operates on dual supplies ranging from -3 V to +15 V or single supply configurations. Key electrical parameters include a maximum bandwidth of 500 MHz, a typical off-isolation of -80 dB at 5 MHz, and a maximum on-resistance of 60 Ohms. Switching times are specified with a maximum turn-on time of 70 ns and a maximum turn-off time of 50 ns. The component supports an operating temperature range from -40 °C to +85 °C.
