Resources for 723644
Description
The 723644 is a CMOS bidirectional synchronous (clocked) FIFO. Two independent 1K 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.
