The ’HC4049 and ’HC4050 are fabricated with high-speed  
silicon gate technology. They have a modified input  
protection structure that enables these parts to be usedas  
logic level translators which convert high-level logic to a low-  
level logic while operating off the low-level logic supply. For  
example, 15-V input pulse levels can be down-converted to  
C = 15pF, T = 25 C

or inverters without level translation. The ’HC4049 and  
’HC4050 are enhanced versions of equivalent CMOS types.
