DESCRIPTION
The IC is intended to reduce the costs of products with a large
number of inputs and also to reduce software overhead by gen-
erating an interrupt on pin change. To decrease the system power
dissipation the external driver transistors are only active for
20
μs
of a
7
ms frame corresponding to
140
Hz polling frequency.
All inputs compare with the internal reference, will be debounced
and can be monitored by the SPI. Additionally the inputs IN
15
and
IN
14
are available on their outputs D
15
and D
14
directly without
debouncing.
