DESCRIPTION
The IC is designed for communication via bidirectional serial data
channels. In addition to the level conversion of transmit and re-
ceive signals from the micro processor’s voltage level to the
12
V
bus level, the device includes plausibility checks in order to guar-
antee undisturbed bus communication in case of corrupted data
from the micro controller.
Undefined states are avoided during low voltage conditions by
means of a Power-on-Reset which blocks the outputs. The inputs
feature internal pull-up and pull-down current sources to main-
tain defined levels.
The bus pins TRM and REC feature a wide input voltage range
from –
24
V to +
40
V independent of VS and VDD. This ensures that
in case of missing ground or power supply connection the opera-
tion of other devices using the bus is not affected.
