Single supply voltage ranges from 3- to 12-V while dual supply operation is recommended with "3 to "6 V. as determined by a 3-bit binary address (A0, A1, A2). The DG9409 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 DG9408 is an 8-channel single-ended analog multiplexer designed to connect one of eight inputs to a common output FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATION DG9408 DG9409 QFN16 QFN16 S1 A2 V- D S1b Db V- Da 16 15 14 13 16 15 14 13 S2 1 12 S5 S2b 1 12 S1a GND 2 11 S6 GND 2 11 S2a S3 3 10 EN S3b 3 10 EN S4 4 9 S7 S4b 4 9 S3a Decoder/Driver Decoder/Driver 5 6 7 8 5 6 7 8 A0 V+ A1 S8 A0 V+ A1 S4a Top View Document Number: 71870 S-21060—Rev.
