7.4.1 Minimum Input Pulse Operation
The UCC27712 device has a minimum turn-on, turn-off pulse transfer function to the output pin from the input pin. This function ensures UCC27712 is in the correct state when the input signal is very narrow. The function is summarized in Figure 36 and Figure 37. The tON which is 25 ns typical is shown in Figure 36 and tOFF which is 35ns typical is shown in Figure 37
