Overview
The CD74HC4050PWR is a high-speed CMOS logic hex buffer produced by Texas Instruments. This component is part of the HC series, known for its high-speed silicon gate technology and modified input protection structure. It is designed to operate as logic level translators, converting high-level logic to low-level logic while running on a low-level logic supply. For instance, it can down-convert 15-V input pulse levels to 0-V to 5-V logic levels. The device also serves as simple buffers or inverters without level translation, making it versatile in various digital circuit applications.
