The SOUT output is the end of the shift Any of the X or Y pins may serve as an input or output. Any or register, and may be connected to the SIN input of the next all of the X terminals may be programmed to connect to any or AD75019. all of the Y terminals. The switches can accommodate signals The AD75019 is fabricated in Analog Devices BiMOS II with amplitudes up to the supply rails and have a typical on- process. This epitaxial BiCMOS process features CMOS resistance of 150 W . devices for low distortion switches and bipolar devices for Data is loaded serially via the SIN input and clocked into an on- ESD protection. board 256-bit shift register via SCLK. When all the switch set- tings have been programmed, data is transferred into a set of 256 latches via PCLK. The serial shift register is dynamic, so there is a minimum clock rate of 20 kHz. The maximum clock rate of 5 MHz allows loading times as short as 52 m s. The switch control latches are static and will hold their data as long as power is applied. REV.
