Philips 74F647 74F649 Data Sheet
Summary
The 74F647 and 74F649 are high-performance octal transceivers/registers designed for reliable data transfer in digital circuits. Featuring open-collector outputs, these components enable complex bus management by multiplexing data from input buses or internal storage registers (A and B). This technical manual serves system designers and electrical engineers needing comprehensive details on functionality, pin configurations, loading specifications, and operating modes—including real-time transmission and isolated data storage—to efficiently implement advanced communication systems.

Frequently Asked Questions
What voltage must be used for these transceivers?
The device operates at a supply voltage of V = 5V ±10%.
Under what condition can I store data in the registers?
Data is stored when the Output Enable (OE) pin is High, which enables FEATURES mode.
Are these devices suitable for life support systems?
No, they are explicitly not designed for use in life support appliances or systems.
How does the chip facilitate data transfer?
It supports multiplexed transmission of data directly from either the input bus (A or B) or from the internal registers.
