The SN74ACT7811 is a 1024 × 18-bit FIFO for high speed and fast access times. It processes data at rates up to 40 MHz and access times of 15 ns in a bit-parallel format. Data outputs are noninverting with respect to the data inputs. Expansion is easily accomplished in both word width and word depth. The SN74ACT7811 has normal input-bus-to-output-bus asynchronous operation. The special enable circuitry adds the ability to synchronize independent read and write (interrupts or requests) to their respective system clock. The SN74ACT7811 is characterized for operation from 0 °C to 70°C. |
