Product specification
Hex inverting high-to-low level shifter
74HC4049
FEATURES
Output capability: standard

CC
category: SSI
GENERAL DESCRIPTION
The 74HC4049 is a high-speed Si-gate CMOS device and
is pin compatible with the “4049” of the “4000B” series. It
is specified in compliance with JEDEC standard no. 7A.
The 74HC4049 provides six 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 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 V
CC
and is the same as mentioned in the family characteristics.
At the same time each part can be used as a simple
inverter without level translation.
APPLICATIONS
Converting 15 V logic (“4000B” series) down to 2 V logic.
