Part Number: CD4049, CD4049UBE, CD4049BE, CD4049UBF

Function : CMOS Hex Buffer/Converter

Package: DIP 16 Pin type

Manufacturer: Harris, RCA, Intersil


CD4049 CMOS Hex Buffer Converter


The CD4049 is an inverting hex buffer and features logic level conversion using only one supply (voltage (VCC). The input signal high level (VIH) can exceed the VCC supply voltage when this device is 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. (VCC = 5V, VOL ≤ 0.4V, and IOL ≥ 3.3mA.
