CD4049UBE CMOS Hex Inverting Buffer and Converter (DIP)

The CD4049UBE is a hexagonal CMOS integrated circuit containing six inverters that function as buffers and logic-level converters. Housed in a standard 16-pin DIP package, it enables efficient logic-level conversion using a single supply voltage (VCC).

A key feature of the CD4049UBE is its ability to accept input signals whose high-level voltage (VIH) can exceed the supply voltage VCC, making it ideal for level-shifting applications. It is specifically designed to bridge CMOS and DTL/TTL technologies, capable of directly driving two DTL/TTL loads without intermediate circuitry.
