U74HC4049 - HEX INVERTING HIGH-TO-LOW LEVEL SHIFTER

General 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.

Key Features

  • S.
  • Inputs accept voltages to 15V.
  • Low power dissipation.
  • Enable to be used as a logic level translator.

UNISONIC TECHNOLOGIES CO., LTD U74HC4049 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.
