High-Speed CMOS Logic
Hex Buffers, Inverting and Non-Inverting
Description
The 鈥橦C4049 and 鈥橦C4050 are fabricated with high-speed
silicon gate technology. They have a modi鏗乪d 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
0-V to 5-V logic levels. The modi鏗乪d 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 鈥橦C4049 and
鈥橦C4050 are enhanced versions of equivalent CMOS types.
