FEATURES

Eight discrete inputs

Senses GND/OPEN discrete signals.

Meet input threshold and hysteresis requirements specified per Airbus ABD0100H specification.

Thresholds: 4.5 V / 10.5 V, Hysteresis: 3V

1 mA input current to prevent dry relay contacts.

Internal isolation diode.

Uses external series 3 kΩ resistors on inputs to implement lightning transient immunity of DO160, Section 22

Level 3, and higher levels with the addition of small TVS devices.

Inputs protected from Lightning Induced Transients per DO160E, Section 22, Cat A3 and B3 plus waveform 5A

to 500 V.

Serial I/O interface to read data register

Direct interface to Serial Peripheral Interface (SPI) port.

TTL/CMOS compatible inputs and Tristate output

10 MHZ Max Data Rate

Serial input to expand Shift Register

Pin compatible with DEI1066

Logic Supply Voltage (VCC):

Analog Supply Voltage (VDD):

16L SOIC EP package
