8K x 36 SyncFIFO, 5.0V

The 723673 is a 8K x 36 unidirectional Sync FIFO memory which supports clock frequencies up to 83 MHz and has read access times as fast as 8ns. 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. This device can operate in the IDT Standard mode or the First Word Fall Through mode.
