description  
The SN74V3640, SN74V3650, SN74V3660, SN74V3670, SN74V3680, and SN74V3690 are exceptionally  
deep, high-speed CMOS, first-in first-out (FIFO) memories, with clocked read and write controls and a flexible  
bus-matching ×36/×18/×9 data flow. These FIFOs offer several key user benefits:  
Flexible ×36/×18/×9 bus matching on both read and write ports  
The period required by the retransmit operation is fixed and short.  
The first-word data-latency period, from the time the first word is written to an empty FIFO to the time it can  
be read, is fixed and short.  
High-density offerings up to 1 Mbit  
Bus-matching synchronous FIFOs are particularly appropriate for network, video, signal processing,  
telecommunications, data communications, and other applications that need to buffer large amounts of data  
and match buses of unequal sizes.  
Each FIFO has a data input port (Dn) and a data output port (Qn), both of which can assume 36-bit, 18-bit, or  
9-bit width, as determined by the state of external control pins’ input width (IW), output width (OW), and bus  
matching (BM) during the master-reset cycle.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
