DESCRIPTION

The HCF4049UB is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP and SOP packages.It is an inverting Hex Buffer/Converter and feature logic level conversions using only one supply voltage (V DD ).

The input high level signal (V IH )can exceed the V DD supply voltage when these devices are used

for logic level conversions.This device is intended for use as CMOS to DTL/TTL converters and can drive directly two DTL/TTL loads (V DD =5V,V OL ≤0.4V and I OL ≤ 3.2mA.
