The DEI1167 is an eight-channel parallel-output 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 a parallel 3-state output.

DEI1184 is an eight-channel discrete-to digital interface IC implemented in an HV DIMOS technology. It senses eight discrete signals of the type commonly found in avionic systems and converts them to serial logic data. Each input can be individually configured as either GND/OPEN or 28V/OPEN format input via a serial data input. The discrete 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.

DEI1188 is an eight-channel discrete-to-digital interface IC implemented in an HV DIMOS technology. It senses eight GND/OPEN discrete signals of the type commonly found in avionic systems and converts them to serial logic data. The discrete 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.
