DG304BDJ-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG304BDJ-E3 is a dual single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It operates within a supply voltage range of ±15 V to ±20 V and supports signal voltages up to ±18 V. The device features a maximum on-resistance of 75 Ohms and a typical off-isolation of -60 dB. Switching times are specified with a maximum turn-on time of 150 ns and a maximum turn-off time of 130 ns. It functions reliably across an extended temperature range from -40°C to +85°C and is housed in a 14-pin PDIP package.
