8CH GND/OPEN DISCRETE
INTERFACE IC W/ EXT HV
PROTECTION
FEATURES
• Eight discrete inputs
o Senses GND/OPEN discrete signals.
o Meet input threshold and hysteresis requirements specified per AirBus ABD0100H specification.
Thresholds: 4.5V/10.5V, Hysteresis: 3V
o 1mA input current to prevent dry relay contacts.
o Internal isolation diode.
o Uses external series 3Kohm resistors on inputs to implement lightning transient immunity of 1600V and higher.
i.e.: DO160E, Section 22, Levels 4 and 5.
o Inputs protected from Lightning Induced Transients per DO160E, Section 22, Cat A3 and B3 plus waveform 5A
to 500V.
• Serial I/O interface to read data register
o Direct interface to Serial Peripheral Interface (SPI) port.
o TTL/CMOS compatible inputs and Tristate output
o 10MHz Max Data Rate
o Serial input to expand Shift Register
• Pin compatible with DEI1066
• Logic Supply Voltage (VCC):
3.3V +/-5%
• Analog Supply Voltage (VDD):
12.0V to 16.5V
• 16L SOIC EP package
