DATASHEET DG408, DG409 Single 8-Channel/Differential 4-Channel, CMOS Analog Multiplexers FN3283 Rev 8.00 Jun 13, 2006 The DG408 Single 8-Channel, and DG409 Differential 4-Channel monolithic CMOS analog multiplexers are drop-in replacements for the popular DG508A and DG509A series devices. They each include an array of eight analog switches, a TTL/CMOS compatible digital decode circuit for channel selection, a voltage reference for logic thresholds and an ENABLE input for device selection when several multiplexers are present. The DG408 and DG409 feature lower signal ON resistance (<100) and faster switch transition time (tTRANS < 250ns) compared to the DG508A or DG509A. Charge injection has been reduced, simplifying sample and hold applications.
