Technical Specifications

The IDT7026S25J operates on a single 5V power supply. It comes in a Ceramic Leaded package. Each port has independent address, data, and control signals for asynchronous read and write operations. The on-chip arbitration logic manages conflicts when both ports attempt to access the same memory location simultaneously.
