Description
The 72V3656 is a 2K x 36 x 2 Triple Bus sync FIFO memory that is a 3.3V version of the 723656. The enables for each port are arranged to provide a simple bidirectional interface between microprocessors and/or buses with synchronous control. This device can operate in the IDT Standard mode or First Word Fall Through mode. Two 72V3656 FIFO's can be combined with unidirectional FIFO's capable of First Word Fall Through timing (i.e. the SuperSync FIFO family) to form a depth expansion.
