CD4049UBC • CD4050BC
Hex Inverting Buffer •
Hex Non-Inverting Buffer
General Description
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.
Features
■Wide supply voltage range: 3.0V to 15V
■Direct drive to 2 TTL loads at 5.0V over full temperature range
■High source and sink current capability
■Special input protection permits input voltages greater than VDD
Applications
•CMOS hex inverter/buffer
•CMOS to DTL/TTL hex converter
•CMOS current “sink” or “source” driver
•CMOS HIGH-to-LOW logic level converter

Note 1: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed; they are not meant to imply that the devices should be operated at these limits. The table of “Recommended Operating Conditions” and “Electrical Characteristics” provides conditions for actual device operation.
Note 2: VSS = 0V unless otherwise specified.
