General Description

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.
