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 SN74ACT2235 is arranged as two 1024 × 9-bit FIFOs for high speed and fast access times.  
It processes data at rates up to 50 MHz, with access times of 25 ns in a bit-parallel format.  
The SN74ACT2235 consists of bus-transceiver circuits, two 1024 × 9-bit FIFOs, and control circuitry arranged  
for multiplexed transmission of data directly from the data bus or from the internal FIFO memories. Enable (GAB  
and GBA) inputs are provided to control the transceiver functions. The select-control (SAB and SBA) inputs are  
provided to 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 2 shows the eight fundamental bus-management functions that can be performed with the  
SN74ACT2235.  
For more information on this device family, see the application report, 1K × 9 × 2 Asynchronous FIFO  
SN74ACT2235, literature number SCAA010.  
The SN74ACT2235 is characterized for operation from 0°C to 70°C.
