The CD74HC40105E, manufactured by Texas Instruments, is a high-speed CMOS logic device designed as a 4-bit by 16-word FIFO (First-In, First-Out) register. This component facilitates asynchronous data handling with an architecture that accommodates 64 bits arranged in a 16 x 4 configuration. It operates efficiently over a voltage range of 2 V to 6 V. The FIFO register features integrated logic that allows for orderly data storage and retrieval, ensuring that data is outputted in the same sequence it was inputted, effectively managing data flow in electronic systems.
