the dg408 is an 8-channel single-ended analog multiplexer designed to connect one of eight inputs to a common output as determined by a 3-bit binary address (a 0 , a 1 , a 2 ). the dg409 is a dual 4-channel differential analog multiplexer designed to connect one of four differential inputs to a common dual output as determined by its 2-bit binary address (a 0 , a 1 ). break-before-make switching action protects against momentary crosstalk between adjacent channels. an on channel conducts current equally well in both directions. in the off state each channel blocks voltages up to the power supply rails. an enable (en) function allows the user to reset the multiplexer/demultiplexer to all switches off for stacking several devices. all control inputs, address (a x ) and enable (en) are ttl compatible over the full specified operating temperature range. applications for the dg408/409 include high speed data acquisition, audio signal switching and routing, ate systems, and avionics. high performance and low power dissipation make them ideal for battery operated and remote instrumentation applications. designed in the 44-v silicon-gate cmos process, the absolute maximum voltage rating is extended to 44 v. additionally, single supply operation is also allowed. an epitaxial layer prevents latchup. for additional information please see technical article ta201 (faxback number 70600).
