All inputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage. All floating bus terminals during High Z State don’t need external pull-up or pull-down resistor. Figure 1: Logic Diagram DESCRIPTION The 74VCXHQ163245 is a dual supply low voltage CMOS 1……
