The DG408L/409L are low voltage pin -for-pin compatible companion devices to the industry standard DG408/409 with improved performance. Using BiCMOS wafer fabrication technology allows the DG408L/409L to operate on single and dual supplies. Single supply voltage ranges from to 12-V while dual supply operation is recommended with "6 V. The an 8-channel single-ended analog multiplexer designed to connect one of eight inputs to a common output as determined a 3-bit binary address A1, A2). The 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/409L provides lower on-resistance, faster switching time, lower leakage, less power consumption and higher off-Isolation than the DG408/409.
