The CD4049UBC and CD4050BC hex buffers are monolithic
complementary MOS (CMOS) integrated circuits constructed
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
 Wide supply voltage range: 3.0V to 15V
 Direct drive to 2 TTL loads at 5.0V over full temperature
range
 High source and sink current capability
 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
