DG541DJ

Analog Switches - Special Purpose Overview

The DG541DJ is a wideband/video switch IC manufactured by Vishay Siliconix, housed in a 16-pin Plastic DIP package. It features four SPST channels built on D/CMOS process technology. The device operates within a supply voltage range of -3 V to +15 V and supports an analog signal range from -5 V to +5 V. Key electrical parameters include a maximum bandwidth of 500 MHz, a maximum on-resistance of 60 Ohms, and a turn-on time of 70 ns. It provides typical off-isolation of -80 dB at 5 MHz and exhibits low crosstalk.
