CD4049UB, CD4050B

CMOS Hex Buffer/Converters

The Harris CD4049UB and CD4050B are inverting and

non-inverting hex buffers, respectively, and feature logic-

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.
