CD4049UBC • CD4050BC
Hex Inverting Buffer •
Hex Non-Inverting Buffer
General Description
The CD4049UBC and CD4050BC hex buffers are mono-
lithic complementary MOS (CMOS) integrated circuits con-
structed with N- and P-channel enhancement mode
transistors. These devices feature logic level conversion
using only one supply voltage (V
DD
). The input signal high
level (V
IH
) can exceed the V
DD
supply voltage when these
devices are used for logic level conversions. These
devices are intended for use as hex buffers, CMOS to DTL/
TTL converters, or as CMOS current drivers, and at V
DD
=
5.0V, they can drive directly two DTL/TTL loads over the
full operating temperature range.
Features
s
Wide supply voltage range:
3.0V to 15V
s
Direct drive to 2 TTL loads at 5.0V over full temperature
range
s
High source and sink current capability
s
Special input protection permits input voltages greater
than V
DD
Applications
• CMOS hex inverter/buffer
• CMOS to DTL/TTL hex converter
• CMOS current “sink” or “source” driver
• CMOS HIGH-to-LOW logic level converter

Note 1:
“Absolute Maximum Ratings” are those values beyond which the
safety of the device cannot be guaranteed; they are not meant to imply that
the devices should be operated at these limits. The table of “Recom-
mended Operating Conditions” and “Electrical Characteristics” provides
conditions for actual device operation.
