DEI1067-SES-G
The DEI1067 is an eight-channel discrete-to digital interface BICMOS device. It senses eight Ground/Open discrete signals of the type commonly found in avionic systems. The data is read from the device via an eight-bit serial shift register with 3-state output. This serial interface is compatible with the industry standard Serial Peripheral Interface (SPI) bus.
