The IDT72805LB, IDT72815LB, IDT72825LB, IDT72835LB, and IDT72845LB are dual-directional synchronous FIFO chips produced by Integrated Device Technology (IDT) company. They have the characteristics of large capacity, high speed, flexible design, and small size. They are suitable for network switching, two-level parallel data prioritization, bidirectional data transfer, bus-matching between 18-bit and 36-bit data paths, 36-bit/package width expansion, and 8192 words/package depth expansion.
The IDT72805LB, IDT72815LB, IDT72825LB, IDT72835LB, and IDT72845LB are dual 18-bit-wide synchronous First-In, First-Out (FIFO) memories. Each device is functionally equivalent to two independent FIFOs with all associated control, data, and flag lines assigned to independent pins.
A +5V power supply is required.
