Additional Details

The UPD74HC4050G-E1 operates by shifting the input voltage level down to the level of the supply voltage (VCC). The input signals can be at a higher voltage than VCC, but the output signals will never exceed VCC. The device provides a direct, non-inverting translation.

This device is commonly available in a SOIC (Small Outline Integrated Circuit) package.
