The DG406 monolithic CMOS analog multiplexer are drop-in replacements for the popular DG506A device. It include an array of sixteen analog switches, a TTL and 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. These multiplexers feature lower signal ON-resistance (< 300ns) compared to the DG506A and DG507A. Charge injection has been reduced, simplifying sample and hold applications. The improvements in the DG406 series are made possible by using a high voltage silicon-gate process. An epitaxial layer prevents the latch-up associated with older CMOS technologies. The 44V maximum voltage range permits controlling 30VP-P signals when operating with ±15V power supplies. The sixteen switches are bilateral, equally matched for AC or bidirectional signals. The ON-resistance variation with analog signals is quite low over a ±5V analog input range.
