IDT723672
Description
The IDT723652/723662/723672 is a monolithic, high-speed, low-power, CMOS Bidirectional SyncFIFO (clocked) memories which support clock frequencies up to 83MHz and have read access times as fast as 8ns. Two independent 2,048/4,096/8,192 x 36 dual-port SRAM FIFOs on board each chip buffer data in opposite directions.
