LH543EP - Brand New Texas Instruments IC Chips
-
FUNCTIONAL DESCRIPTION
The LH543601 contains 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 256 by 36 bits. The LH543601 is ideal
either for wide unidirectional applications or for bidirectional data applications; component count and board area are reduced.
