6 Channel CMOS Hex Inverting Buffer and Converter, 3V to 18V, CIP 16 - 

The CD4049UBE is a CMOS hex inverting buffer/converter in 16 pin DIP package. It features logic level conversion using single supply voltage (VCC). The input high level signal (VIH) can exceed VCC supply voltage when this device is used for logic level conversions. The CD4049UBE is intended for use as CMOS to DTL/TTL converters and can drive directly two DTL/TTL loads. Typical application includes CMOS to DTL/TTL hex converter, CMOS current sink or source driver and CMOS high to low logic level converter.
