These benefits are obtained without sacrificihg the lowO resistance (75n) or low leakage current (500pA), the main features of an analog switch. The AD7510DI and AD7511DI consist of four independent SPST analog switches packaged in either a 16-pin DIP or a 20- terminal surface mount package. They differ only in that the digitalcontrol logicis inverted. The AD7512DI has two inde pendent SPDT switches packaged either in a 14-pin DIP or a 20-terminal surface mount package. Very low power dissipation, overvoltage protection and TTL/ CMOS direct interfacing are achieved by combining a unique circuit design and a dielectrically isolated CMOS process. Silicon nitride passivation ensures long term stability while monolithic construction provides reliability. The AD7510 and AD7512 are no longer available.
