512 X 18 X 2 Bidirectional Asynchronous FIFO Memory

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 Enable inputs (GAB and GBA) control the transceiver functions. The SAB and SBA control inputs select whether real-time or stored data is transferred. The circuitry used for select control eliminates the typical decoding glitch that occurs in a multiplexer during the transition between stored and real-time data. Figure 1 illustrates the eight fundamental bus-management functions that CAN be performed with the SN74ABT7820.
The SN74ABT7820 is characterized for operation from 0C to 70C.
