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 SN54ABT7820 is arranged as two 512 × 18-bit FIFOs for high speed and fast access times.

It processes data at rates up to 40 MHz, with access times of 18 ns in a bit-parallel format.

The SN54ABT7820 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 SN54ABT7820.

The SN54ABT7820 is characterized for operation over the full military temperature range of –55°C to 125°C.
