CD4049 Hex Inverting IC Buffer/Converter

CD4049 Hex Inverting IC Buffer/Converter is a CMOS logic-based hex inverter IC consisting of six inverters on a single package. We can use it in high voltage applications as it has a wide range of operating voltage from 3V to 18V. As it is an inverter IC and the function of an inverter is to convert the logic level HIGH to LOW and LOW to HIGH, therefore it is used in logic level conversions. More than 18V can damage the IC but the input voltage signal value can be greater than supply voltage especially in conversion of logic levels.

Pin Configuration Details

This IC has sixteen pins. The description of all these pins are mentioned in the table below
