DG408DJ

The DG408DJ is a single 8-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 device feature lower signal ON resistance (<lt/>250ns). Charge injection has been reduced, simplifying sample and hold applications. An epitaxial layer prevents the latch-up associated with older CMOS technologies. The analog 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.

• <lt/>11mW Low power consumption (PD)
