MLPQ
The DEI2084/85-Mxx versions are alternate package pin-
outs of the DEI1084/85-Mxx to provide access to the
/TXSEL output in the MLPQ package.
The enhancements relative to the DEI1016 transceiver
include: 32x32 bit FIFO for transmitter, 32x32 bit FIFO
for each receiver, a status register, label recognition
capability, bit timing feature and choice of scrambled or
unscrambled ARINC data output.

The DEI1085 version requires external serial 10KOhm
resistors on the receiver inputs. This simplifies the
implementation of external lightning protection networks.
The DEI1084 version has on-chip 10KOhm resistors and
do not require external resistors on the inputs.
