M74HC4049RM13TR Description

The M74HC4049RM13TR from STMicroelectronics is a high-performance inverting buffer IC belonging to the 74HC series, designed for 2V to 6V operation. This surface-mount device integrates six inverting buffers, each handling 1-bit data, making it ideal for logic-level conversion and signal conditioning. Packaged in a 16-pin SOIC and supplied in Tape & Reel (TR), it ensures compatibility with automated assembly processes. With a balanced output current of 5.2mA (sink/source), it supports robust signal driving in mixed-voltage systems. Though marked Obsolete, it remains relevant for legacy designs due to its ROHS3 compliance and REACH-unaffected status.
