Texas Instruments CD4049UBE CMOS Hex Inverting Buffer and Converter, 16-Pin DIP

The Texas Instruments CD4049UBE is a high-performance CMOS hex inverting buffer and logic level converter, supplied in a robust 16-pin Dual Inline Package (DIP). It is engineered to facilitate seamless interfacing between different logic families, most notably converting CMOS signals to DTL or TTL levels using a single supply voltage (VCC). This makes it an indispensable component in mixed-logic system design where voltage level matching is critical.

A key feature of this device is its ability to accept input high-level signals (VIH) that can exceed the VCC supply voltage, providing greater flexibility in level-shifting applications. It is capable of directly driving two DTL or TTL loads, thanks to its high sink current capability, simplifying circuit design and reducing component count. The device is 100% tested for quiescent current, ensuring reliable and power-efficient operation.
