PHILIPS 74HC HCT40105 Data Sheet
Summary
The 74HC/HCT40105 is a high-speed, asynchronous First-In/First-Out (FIFO) shift register designed to act as an essential buffer for reliable data transfer between systems operating on different clock domains. It features independent input and output controls, advanced status indicators, and robust reset capabilities. This manual provides comprehensive technical specifications, detailed operational protocols, timing diagrams, pinning information, and engineering guidelines necessary for specialized electronics designers and engineers integrating high-reliability buffering solutions into complex circuit designs.

Frequently Asked Questions
How do I check if data is available or if space is open in the FIFO?
Use the Data-Out Ready Output (DOR) to indicate if the FIFO contains data, and the Data-In Ready Output (DIR) to indicate when an empty location appears.
What is the maximum operating clock frequency for this device?
The maximum specified clock frequency (f) is 33 MHz for products using the 74HC designation.
How does data transfer through the FIFO register occur?
Data enters via the Shift-in (SI) input and exits via the Shift-out (SO) output, operating according to a First-In/First-Out principle.
Can this device be used in life support systems?
No; these products are explicitly stated as not being designed for use in life support appliances or critical systems.
