The DG409L is low voltage pin-for-pin compatible companion devices to the industry standard DG409 with improved performance.Using BiCMOS wafer fabrication technology allows the DG409L to operate on single and dual supplies. Single supply voltage ranges from 3 V to 12 V while dual supply operation is recommended with ± 3 V to ± 6 V.The DG409L is a dual 4 channel differential analog multiplexer designed to connect one of four differential inputs to a common dual output as determined by its 2 bit binary address (A0, A1). Break-before-make switching action to protect against momentary crosstalk between adjacent channels.The DG408L, DG409L provides lower on-resistance, faster switching time, lower leakage, less power consumption, and higher off-isolation than the DG408, DG409.
