74HC4050

The 74HC4050 is a high-speed Si-gate CMOS device and is pin compatible with the "4050" of the "4000B" series. It is specified in compliance with JEDEC standard no. 7A.

The 74HC4050 provides six non-inverting buffers with a modified input protection structure, which has no diode connected to V_CC. Input voltages of up to 15 V may therefore be used. This feature enables the non-inverting buffers to be used as logic level translators, which will convert high level logic to low level logic, while operating from a low voltage power supply. For example 15 V logic ("4000B series") can be converted down to 2 V logic.

The actual input switch level of the 74HC4050 remains related to the V_CC and is the same as mentioned in the family characteristics.
