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-channel 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 conversions 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
