CD4049UB and CD4050B devices are inverting and non-inverting hex buffers and only one supply voltage (VCC) It has the feature of transforming at the logic level using The input signal high level (VIH) may exceed the VCC supply voltage when these devices are used for logic level conversions. These devices are designed for use as CMOS to DTL or TTL converters and can directly drive two DTL or TTL loads.
