Description
The CD74HC4049 and CD74HC4050 are fabricated with
high-speed silicon gate technology. They have a modified
input protection structure that enables these parts to be
used as 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 0-V to 5-V logic levels. The modified input
protection structure protects the input from negative
electrostatic discharge. These parts also can be used as
simple buffers or inverters without level translation. The
CD74HC4049 and CD74HC4050 are enhanced versions of
equivalent CMOS types.
