CD4049UB, CD4050B
CMOS Hex Buffer/Converters
The CD4049UB and CD4050B devices are inverting and
non-inverting hex buffers, respectively, and feature logic-
level conversion using only one supply voltage (V
CC
). The
input-signal high level (V
IH
) can exceed the V
CC
supply
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
loads. (V
CC
= 5V, V
OL
≤ 0.4V, and I
OL
≥ 3.3mA.)
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.
