DG509BEJ-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG509BEJ-E3 is a dual 4-channel differential analog multiplexer manufactured by Vishay Siliconix. It connects one of four differential inputs to a common dual output via a 2-bit binary address (A0, A1). The device operates with single or dual power supplies ranging from ±5 V to ±20 V, or up to 44 V single supply. Key electrical parameters include a maximum on-resistance of 380 Ω, a -3 dB bandwidth of 250 MHz, and an enable turn-on time of 250 ns. It features TTL-compatible control inputs, break-before-make switching, and operates within a temperature range of -40 °C to +125 °C in a 16-lead PDIP package.
