2 / 30 page ![]() 2 COMMERCIALTEMPERATURERANGE IDT723663/723673 CMOS SyncFIFOTM WITH BUS-MATCHING 4,096 x 36 x 2 and 8,192 x 36 x 2 These devices are synchronous (clocked) FIFOs, meaning each port employs a synchronous interface. All data transfers through a port are gated totheLOW-to-HIGHtransitionofaportclockbyenablesignals.Theclocksfor each port are independent of one another and can be asynchronous or coincident. The enables for each port are arranged to provide a simple bidirectionalinterfacebetweenmicroprocessorsand/orbuseswithsynchro- nouscontrol. DESCRIPTION The IDT723663/723673 is a monolithic, high-speed, low-power, CMOS unidirectional Synchronous (clocked) FIFO memory which supports clock frequenciesupto83MHzandhasreadaccesstimesasfastas8ns.The4,096/ 8,192x36dual-portSRAMFIFObuffersdatafromPortAtoPortB.FIFOdata onPortBcanoutputin36-bit,18-bit,or9-bitformatswithachoiceofBig-orLittle- Endianconfigurations.
