CD4050BDR [Texas Instruments]

The CD4049UB and CD4050B devices are inverting and noninverting hex buffers, and feature logic-level conversion using only one supply voltage (V CC). They are intended for use as CMOS to DTL or TTL converters and can drive directly two DTL or TTL loads. The CD4049UB is inverting and the CD4050B is noninverting, with high sink current for driving 2 TTL loads, high-to-low level logic conversion, and 100% tested for quiescent current at 20 V.
