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 (VDD). The input signal high
level (VIH) can exceed the VDD 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 VDD =
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 VDD
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.

DC Electrical Characteristics (Continued)
Note 4: These are peak output current capabilities. Continuous output current is rated at 12 mA maximum. The output current should not be allowed to
exceed this value for extended periods of time. IOL and IOH are tested one output at a time.
