The DG3408/3409 uses BiCMOS wafer fabricationtechnology that allows the DG3408/3409 to operate on singleand dual supplies. Single supply voltage ranges from 3to 12 V while dual supply operation is recommended with± 3 to ± 6 V.The DG3408 is an 8-channel single-ended analogmultiplexer designed to connect one of eight inputs to acommon output as determined by a 3-bit binary address(A0, A1, A2). The DG3409 is a dual 4-channel differentialanalog multiplexer designed to connect one of fourdifferential inputs to a common dual output as determined byits 2-bit binary address (A0, A1). Break-before-makeswitching action to protect against momentary crosstalkbetween adjacent channels.
