General Description
SN74ACT7882 General Description
A FIFO memory is a storage device that allows data to be written into and read from its array at independent data rates. The SN74ACT7882 is organized as 2048 bits deep × 18 bits wide. The SN74ACT7882 processes data at rates up to 67 MHz and access times of 11 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 SN74ACT7882 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 SN74ACT7882 is characterized for operation from 0°C to 70°C.
