CD4049UBM/CD4049UBC Hex Inverting Buffer CD4050BM/CD4050BC Hex Non-Inverting Buffer
March 1988
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
