SN74ACT3651-15PQ

Logic–FIFOs Memory: SN74ACT3651-15PQ application field and working principleSN74ACT3651–15PQ, the logic–FIFO memories from Texas Instruments, is one of the most popular multiplex register circuitsanalog design is based on the principles of CMOS and TTL technology. It comprises two 8-bit registers, two 10-bit registers, two 12-bit registers and two 14-bit registers. The registers are connected to the FIFO data registers and the Address Bus. The SN74ACT3651–15PQ can be configured with a single clock signal to facilitate multiplexing of FIFOs with different byte sizes.SN74ACT3651–15PQ offers the following features: 
	
Small size and low power consumption
	
Easy set-up; each register is independently configured with its own address and data buses
	
User-friendly interface; the user is easily able to switch between multiplexing and bypass configurations
	
Power conservation; the circuit can be powered down when not in use, allowing for further savings
	
High-speed operation; the switching speed is typically <3–6 ns
	
Configurable data width; data widths of 8, 10, 12 and 14 bits are supported
The SN74ACT3651–15PQ enables the storage of data into multiple FIFO memories. The data is written into the FIFO memories through the respective data buses, and retrieved through the same data buses. Each register has separate input and output data buses and it operates with the same clock signal. By configuring the address bus, the user can control which register the data is written to and read from. The data within the FIFO memories is stored in the form of a stack, in a LIFO or FIFO configuration. This allows for increased throughput of data as multiple FIFO memories are available for read and write operations at the same time. Furthermore, the user can configure the registers to bypass each other in order to facilitate faster data processing. The SN74ACT3651–15PQ can be used in a wide range of applications, such as communications and process control. In communications, the SN74ACT3651–15PQ can be used to read and write data onto the data bus of various communication networks at high speeds. Furthermore, in process control applications, the SN74ACT3651–15PQ can be used to control the flow of data between different registers. Overall, the SN74ACT3651–15PQ is an efficient and robust multiplex register circuit for FIFO memory operations. Its small size, low power consumption, user-friendly interface and high-speed operation make it an ideal choice for applications requiring the use of FIFO memory technology.
