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 (V_DD)
The input signal high level (V_IH) can exceed the V_DD 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 V_DD 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 V_DD
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}
