GENERAL DESCRIPTION

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 VCC. 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 remains related to the VCC

and is the same as mentioned in the family characteristics.
