The LH543611 and LH543621 contain two FIFO buffers, FIFO #1 and FIFO #2. These operate in parallel, but in opposite directions, for bidirectional data buffering. FIFO #1 and FIFO #2 each are organized as 512 or 1024 by 36 bits. The LH543611 and LH543621 are ideal either for wide unidirectional applications or for bidirectional data applications; component co.
