The CD4049 is a versatile hex inverting buffer/converter integrated circuit, essentially providing six NOT gates (inverters) within a single package. This component is notable for its ability to sink significantly more current than many standard logic gates, with specific variants like the CD4049UB capable of sinking up to 48 mA. Its operating voltage range is typically between 3V and 15V, though some versions may support up to 20V.
A common application for the CD4049 is in level shifting. It can accept a higher input voltage than its supplied VDD, making it useful for interfacing between different voltage domains, such as connecting a 10V signal to a 5V microcontroller. Since the buffers are inverting, a second buffer stage can be used to restore the original logic level if needed, while maintaining the shifted voltage.
Alternatives and equivalents for the CD4049 often include different prefixes and suffixes, such as CD4049BE, NTE4049, HEF4049, TC4049BP, MC14049, or HCF4049, which denote the manufacturer or specific technology used, but maintain the same core functionality and pinout.
