DEI1066-SMB-G
The DEI1066 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 implemented as a Serial Peripheral Interface (SPI) bus, Mode 0 slave.
Features
- Eight GND/OPEN discrete inputs
- Meet electrical requirements for ABD0100F GND/OPEN discrete input.
- Hysteresis provides noise immunity
- Internal pull up resistor with 1mA source current to prevent dry relay contacts.
- Internal isolation diode
- Inputs protected from Lightning Induced Transients per DO160D, Section 22, Cat A3 and B3.
- 3-wire serial interface (/CS, CLK, DO)
- Direct interface to Serial Peripheral Interface (SPI) port.
- TTL/CMOS compatible inputs and Tristate output
- 10MHz Data Rate
- Serial input to expand Shift Register
- Logic Supply Voltage (VCC): 3.3V or 5V
- Analog Supply Voltage (VDD): 5V to 18V
- 16L NB SOIC package
