Product specification

Hex high-to-low level shifter

74HC4050

FEATURES

• Output capability: standard

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

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.

and is the same as mentioned in the family characteristics.

APPLICATIONS

• Converting 15 V logic (“4000B” series) down to 2 V logic.
