Sharp LH543620
The LH543620 is a FIFO (First-In, First-Out) memory device, based on fully-static CMOS RAM technology, capable of containing up to 1024 36-bit words. It can replace four or more nine-bit-wide FIFOs in many applications. The input port and the output port operate independently of each other.| Part No. | LH543620 |
