CD4049UB, CD4050B  
August 1998 - Revised May 2004  
Data sheet acquired from Harris Semiconductor

CMOS Hex Buffer/Converters  
Applications  
The CD4049UB and CD4050B devices are inverting and  
non-inverting hex buffers, respectively, and feature logic-  
• CMOS to DTL/TTL Hex Converter  
• CMOS Current “Sink” or “Source” Driver  
• CMOS High-To-Low Logic Level Converter  
level conversion using only one supply voltage (V ). The  
CC  
supply  
input-signal high level (V ) can exceed the V  
IH  
CC  
voltage when these devices are used for logic-level  
conversions. These devices are intended for use as CMOS  
to DTL/TTL converters and can drive directly two DTL/TTL

The CD4049UB and CD4050B are designated as  
replacements for CD4009UB and CD4010B, respectively.  
Because the CD4049UB and CD4050B require only one  
power supply, they are preferred over the CD4009UB and  
CD4010B and should be used in place of the CD4009UB  
and CD4010B in all inverter, current driver, or logic-level  
conversion applications. In these applications the  
CD4049UB and CD4050B are pin compatible with the  
CD4009UB and CD4010B respectively, and can be  
substituted for these devices in existing as well as in new  
designs. Terminal No. 16 is not connected internally on the  
CD4049UB or CD4050B, therefore, connection to this  
terminal is of no consequence to circuit operation. For  
applications not requiring high sink-current or voltage  
conversion, the CD4069UB Hex Inverter is recommended.
