CD4049UBM CD4049UBC Hex Inverting Buffer
CD4050BM CD4050BC Hex Non-Inverting Buffer
General Description
These hex buffers are monolithic complementary MOS
(CMOS) integrated circuits constructed with N- and P-chan-
nel 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 conver-
sions These devices are intended for use as hex buffers
CMOS to DTL TTL converters or as CMOS current drivers
and at VDD e 5 0V they can drive directly two DTL TTL
loads over the full operating temperature range
Features
Y Wide supply voltage range
3 0V to 15V
Y Direct drive to 2 TTL loads at 5 0V over full tempera-
ture range
Y High source and sink current capability
Y Special input protection permits input voltages greater
than VDD
Applications
Y CMOS hex inverter buffer
Y CMOS to DTL TTL hex converter
Y CMOS current ‘‘sink’’ or ‘‘source’’ driver
Y CMOS high-to-low logic level converter

should be operated at these limits The table of ‘‘Recommended Operating Conditions’’ and ‘‘Electrical Characteristics’’ provides conditions for actual device
operation
