One of our customer is planned to use SN74HC4851.
In product datasheet (Page-7) it was mentioned that ,it doesn’t require any external passive components for signal conditioning (Refer below figure).
Refer figure 2 compared to figure3 (less component).
Their application is to sense high / low switches.
Their switch maximum input voltage range is 32V.
Please clarify the following doubts.
1) Does it can sense switch status - high / low /open ?
2) Does the IC input can withstand up to 32V input without any passive components?
