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.
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
