Product Details
The ADGS1414D contains eight independent SPST switches. A serial peripheral interface (SPI) controls the switches. The SPI has robust error detection features, such as cyclic redundancy check (CRC) error detection, invalid read and write address detection, and SCLK count error detection. It is possible to daisy-chain multiple ADGS1414D devices together. Daisy-chain mode enables the configuration of multiple devices with a minimal amount of digital lines. The route of digital signals and supplies through the ADGS1414D allows for a further increase in channel density. Integrated passive components eliminate the need for external passive components. FUNCTIONAL BLOCK DIAGRAM Figure 1. The ADGS1414D is suited to high density switching applications, such as large switching matrices and fanout applications. Each switch conducts equally well in both directions when on, and each switch has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked. Multifunction pin names may be referenced by their relevant function only.
