CMOS IC
HEX INVERTING HIGH-TO-LOW
LEVEL SHIFTER
„
DESCRIPTION
The U74HC4049 is a high speed Si-gate CMOS device which
contains six independent inverters and they perform the function Y= A .
On the input circuit of this device has 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 inverters 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 example15-V logic
can be converted down to 2-V logic. At the same time each part can
be used as a simple inverter without level translation.
„
FEATURES
* Inputs accept voltages to 15V
* Low power dissipation
* Enable to be used as a logic level translator
