CD4049UBM CD4049UBC Hex Inverting Buffer
CD4050BM CD4050BC Hex Non-Inverting Buffer
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
