PROGRAMMABLE GND/OPN &

28V/OPN DISCRETE INPUT

INTERFACE IC

FEATURES

The DEI1160A is an improved version of the DEI1160 with greater transient voltage immunity, which simplifies the

equipment design for lightning and RF immunity requirements.

Eight discrete inputs

Individually configurable to sense either GND/OPEN or 28V/OPEN(or 28V/GND) discrete signals

Hysteresis provides noise immunity

1mA input current to prevent dry relay contacts.

Internal isolation diode

Inputs protected from Lightning Induced Transients per DO160E, Section 22, Cat A3 and B3.

Inputs protected from Power Input Abnormal Surge per DO160E, Section 16, Cat Z.

Serial I/O interface to read data register and write configuration register

Direct interface to Serial Peripheral Interface (SPI) port.

TTL/CMOS compatible inputs and Tristate output

10MHz Data Rate

Serial input to expand Shift Register
