CD4010B hex buffer/converter may be used as CMOS to TTL or DTL logic-level converters or CMOS high-sink-current drivers. The CD4050B is the preferred hex buffer replacement for the CD4010B in all applications except multiplexers. For applications not requiring high sink current or voltage conversion, the CD4069UB hex inverter is recommended. The CD4010B is supplied in 16-lead hermetic dual-in-line ceramic (D) packages.
