Product Descriptions
A FIFO memory is a storage device that allows data to be written into and read from its array at independent data rates. The SN74ABT7820 is arranged as two 512 × 18-bit FIFOs for high speed and fast access times. It processes data at rates up to 67 MHz with access times of 12 ns in a bit-parallel format.
The SN74ABT7820 consists of bus-transceiver circuits, two 512 × 18 FIFOs, and control circuitry arranged for multiplexed transmission of data directly from the data bus or from the internal FIFO memories.
The SN74ABT7820 is characterized for operation from 0°C to 70°C.
