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= .

On the input circuit of this device has 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 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
