DG406/883

The DG406/883 and DG407/883 monolithic CMOS analog multiplexers are drop-in replacements for the popular DG506A/883 and DG507A/883 series devices. They each include an array of sixteen analog switches, a TTL and CMOS compatible digital decode circuit for channel selec- tion, a voltage reference for logic thresholds, and an ENABLE input for device selection when several multiplex-ers are present.

These multiplexers feature lower signal ON resistance(<100Ω) and faster transition time (t_TRANS <250ns) compared to the DG506A/883 and DG507A/883. 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. A_n epitaxial layer prevents the latch-up associated with older CMOS technolo-gies. The 44V maximum voltage range permits controlling 30V_P-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.
