DG408, DG409, Single 8-channel/Differential 4-channel, CMOS Analog Multiplexer General Description: The DG408 Single 8-Channel and DG409 Differential 4-Channel monolithic CMOS analog multiplexers are a direct replacement for the popular DG508A and DG509A series devices. They each contain 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 multiple multiplexers are present. The DG408 and DG409 have a lower signal ON resistance (<100Ohm) and a faster switching transition time (tTRANS < 250ns) compared to the DG508A or DG509A. Charge injection has been reduced, simplifying sample-and-hold applications. The improvements in the DG408 series are made possible by the use of a high-voltage silicon gate process. An epitaxial layer prevents the latch-up that occurs with older CMOS technologies. The power supplies can be single ended from +5V to +34V or split from +/-5V to +/-20V. The analog switches are double ended and equally suitable for AC or bidirectional signals. The variation in on-resistance for analog signals is quite small over an analog input range of +/-5V.
