CD4049UBMꢀCD4049UBC Hex Inverting Buffer
CD4050BMꢀCD4050BC 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
Features
Y
Wide supply voltage range
30V to 15V
Y
Direct drive to 2 TTL loads at 50V over full tempera-
ture range
Y
Y
logic level conversion using only one supply voltage (V )
DD
High source and sink current capability
Special input protection permits input voltages greater
than V
The input signal high level (V ) can exceed the V
IH
