Overview
The CD74HC4049M96E4 is a high-speed CMOS logic inverter produced by Texas Instruments. This component is part of the HC4049 series, which is fabricated with high-speed silicon gate technology. It is designed to operate as a logic level translator, converting high-level logic signals to low-level logic signals while operating off the low-level logic supply. Additionally, it can function as simple buffers or inverters without level translation. The device features a modified input protection structure that protects against negative electrostatic discharge and offers high noise immunity.
