The ADG508A and ADG509A are CMOS monolithic analog The devices are specified in the 10.8 V to 16.5 V range for multiplexers with eight channels and dual four channels, respec- both single and dual supplies. tively. The ADG508A switches one of eight inputs to a common 2 output, depending on the state of three binary addresses and an 2. Extended Signal Range. The enhanced LC MOS processing enable input. The ADG509A switches one of four differential results in a high breakdown and an increased analog signal inputs to a common differential output, depending on the state range of V to V . SS DD of two binary addresses and an enable input. Both devices have 3. Break-Before-Make Switching. Switches are guaranteed TTL and 5 V CMOS logic-compatible digital inputs. break-before-make so that input signals are protected against momentary shorting. The ADG508A and ADG509A are designed on an enhanced 2 LC MOS process that gives an increased signal capability of VSS 4. Low Leakage. Leakage currents in the range of 20 pA make to VDD and enables operation over a wide range of supply voltages. these multiplexers suitable for high precision circuits. The devices can comfortably operate anywhere in the 10.8 V to 16.5 V single- or dual-supply range. These multiplexers also feature high switching speeds and low R . ON Rev.
