–55oC to 125oC • Balanced Propagation Delay and Transition Times • Signiﬁcant Power Reduction Compared to LSTTL Logic ICs • HC Types - 2V to 6V Operation - High Noise Immunity: NIL = 30%, NIH = 30%of VCC at VCC = 5V Pinout 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 lowlevel 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 ’HC4049 and ’HC4050 are enhanced versions of equivalent CMOS types.
