General Description
Features
■ Wide supply voltage range: 3.0V to 15V
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
■ 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
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
Applications
=
5.0V, they can drive directly two DTL/TTL loads over the
full operating temperature range.
