IR2101 cross-conduction
I think you can count on the matched output delay times within 10 ns for the IR2101 using the test circuit and test method in the datasheet.

Putting both inputs high would pull both outputs high , which is the same as shorting out your load to the same supply voltage.  ( i.e. Brake )

External drivers can then be modified to control the Dead Time to prevent shootthru with L/R decay times using non-linear Diode/R ratios with Ciss.

Measurement Thresholds  ( Note the different threshold levels)


The deadtime can be improved with the (R1//D3,R2//D2 ;)) Diode shunted 10 Ohm R to turn Off faster than On.. The diode has low resistance (~1 ohm)during rapid negative edge Vgs transitions.
