The 72V3641is a 1K x 36 Sync FIFO memory that is a 3.3V version of the 723641. It supports clock frequencies up to 67 MHz and has read access times as fast as 10ns. The FIFO memory has retransmit capability, which allows previously read data to be accessed again. The FIFO operates in First Word Fall Through mode. Communication between each port may take place with two 36-bit mailbox registers. The enables for each port are arranged to provide a simple interface between microprocessors and/or buses with synchronous control.

The 72V3643 is a 1K x 36 Sync FIFO that is a 3.3V version of the 723643. The clocks for each port are independent of one another and can be asynchronous or coincident. The enables for each port are arranged to provide a simple bidirectional interface between microprocessors and/or buses with synchronous control. Communication between each port may bypass the FIFO via two mailbox registers. These devices can operate in the IDT Standard mode word or First Word Fall Through mode.

The 72V3650 2K x 36 SuperSync II FIFO memory with clocked read and write controls offers flexible Bus-Matching x36/x18/x9 data flow and Asynchronous/Synchronous translation on the read or write ports ; SuperSync II FIFO's are appropriate for network, video, telecommunications, data communications and other applications that need to buffer large amounts of data and match busses of unequal sizes.

The 72V3660 4K x 36 SuperSync II FIFO memory with clocked read and write controls offers flexible bus-matching x36/x18/x9 data flow and asynchronous/synchronous translation on the read or write ports. SuperSync II FIFOs are appropriate for network, video, telecommunications, data communications, and other applications that need to buffer large amounts of data and match buses of unequal sizes.

The 72V3670 8K x 36 SuperSync II FIFO memory with clocked read and write controls offers flexible Bus-Matching x36/x18/x9 data flow and Asynchronous/Synchronous translation on the read or write ports ; SuperSync II FIFO's are appropriate for network, video, telecommunications, data communications and other applications that need to buffer large amounts of data and match busses of unequal sizes.

The 72V3672 Bidirectional SyncFIFO (clocked) memory is a 3.3V version of the 723672. Two independent 8K x 36 dual-port SRAM FIFOs on board each chip buffer data in opposite directions. The clocks for each port are independent of one another and can be asynchronous or coincident. The enables for each port are arranged to provide a simple bidirectional interface between microprocessors and/or buses with synchronous control.

The 72V3680 16K x 36 SuperSync II FIFO memory with clocked read and write controls offers flexible Bus-Matching x36/x18/x9 data flow and Asynchronous/Synchronous translation on the read or write ports ; SuperSync II FIFO's are appropriate for network, video, telecommunications, data communications and other applications that need to buffer large amounts of data and match busses of unequal sizes.

The 72V3690 32K x 36 SuperSync II FIFO memory with clocked read and write controls offers flexible Bus-Matching x36/x18/x9 data flow and Asynchronous/Synchronous translation on the read or write ports ; SuperSync II FIFO's are appropriate for network, video, telecommunications, data communications and other applications that need to buffer large amounts of data and match busses of unequal sizes.

The 72V51253 multi-queue flow-control device is a single chip within which between 1 and 4 discrete FIFO queues can be setup. All queues within the device have common data input bus, (write port) and a common data output bus, (read port). Data written into the write port is directed to a respective queue via an internal de-multiplex operation, addressed by the user. Data read from the read port is accessed from a respective queue via an internal multiplex operation, addressed by the user.
