The CD4049UBC and CD4050BC 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 =5.0V, they can drive directly two DTL/TTL loads over the full operating temperature range.
Wide supply voltage range: 3.0V to 15V
Direct drive to 2 TTL loads at 5.0V over full temperaturerange
High source and sink current capability
Special input protection permits input voltages greater than VDD
