Datasheet
Note: The “#” as the suffix of a signal name indicates an “Active Low” signal.
Note 3.1 Buffer types per function on multiplexed pins are separated by a slash “/” Buffer types in
parenthesis represent multiple buffer types for a single pin function.
Note 3.2 This analog input is backdrive protected.

3.3V Operation, 5V Tolerance
The EMC2300 is intended to operate with a nominal 3.3V power supply. The analog voltage pins are
connected to voltage sources at their respective nominal levels. All digital signal pins are 3V switching,
but are tolerant to 5V.
