description  
The SN74ACT7200L, SN74ACT7201LA, and  
SN74ACT7202LA are constructed with dual-port  
SRAM and have internal write and read address  
counters to provide data throughput on a first-in,  
first-out (FIFO) basis. Write and read operations  
are independent and can be asynchronous or  
coincident. Empty and full status flags prevent  
underflow and overflow of memory, and  
depth-expansion logic allows combining the  
storage cells of two or more devices into one  
FIFO. Word-width expansion is also possible.

Data is loaded into memory by the write-enable  
(W) input and unloaded by the read-enable (R)  
input. Read and write cycle times of 25 ns  
(40 MHz) are possible with data access times of  
15 ns.  
NC – No internal connection  
These devices are particularly suited for providing a data channel between two buses operating at  
asynchronous rates. Applications include use as rate buffers from analog-to-digital converters in data-  
acquisition systems, temporary storage elements between buses and magnetic or optical memories, and  
queues for communication systems. A 9-bit-wide data path is provided for the transmission of byte data plus  
a parity bit or packet-framing information. The read pointer can be reset independently of the write pointer for  
retransmitting previously read data when a device is not used in depth expansion.  
The SN74ACT7200L, SN74ACT7201LA, and SN74ACT7202LA are characterized for operation from 0°C  
to 70°C.
