DESCRIPTION
All inputs and outputs 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 must be held HIGH or LOW. December 2001 1/9 DataSheet 4 U .com 74VCHT16245A INPUT EQUIVALENT CIRCUIT IEC LOGIC SYMBOLS PIN DESCRIPTION
