Hex inverting high-to-low level shifter74HC4049
FEATURES
• Output capability: standard
• ICC category: SSI
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.
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
. Input voltages of up to 15 V may
CC
The actual input switch level remains related to the V
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.
