A FIFO memory is a storage device that allows data to be written into and read from its array at independent data rates. The SN54ACT7881 is organized as 1024 × 18 bits and processes data with rates up to 50 MHz and access times of 13 ns in a bit-parallel format. Data outputs are noninverting with respect to the data inputs. Expansion is accomplished easily in both word width and word depth.
The SN54ACT7881 has normal input-bus to output-bus asynchronous operation. The special enable circuitry adds the ability to synchronize independent reads and writes to their respective system clocks.
The SN54ACT7881 is characterized for operation over the full military temperature range of -55°C to 125°C
