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

structure protects the input from negative electrostatic
discharge. These parts also can be used as simple buffers
or inverters without level translation. The ’HC4049 and
’HC4050 are enhanced versions of equivalent CMOS types.
