description  
The SN74ABT3611 is a high-speed, low-power BiCMOS clocked FIFO memory. It supports clock frequencies  
up to 67 MHz and has read access times as fast as 10 ns. A 64 × 36 dual-port SRAM FIFO buffers data from  
port A to port B. The FIFO has flags to indicate empty and full conditions and two programmable flags (almost  
full and almost empty) to indicate when a selected number of words is stored in memory. Communication  
between each port takes place through two 36-bit mailbox registers. Each mailbox register has a flag to signal  
when new mail has been stored. Parity is checked passively on each port and can be ignored if not desired.

wider datapaths.  
The SN74ABT3611 is a clocked FIFO, which means each port employs a synchronous interface. All data  
transfers through a port are gated to the low-to-high transition of a port clock by enable signals. The clocks for  
each port are independent of one another and can be asynchronous or coincident. The enables for each port  
are arranged to provide a simple bidirectional interface between microprocessors and/or buses with  
synchronous control.  
The full flag (FF) and almost-full (AF) flag of the FIFO are two-stage synchronized to the port clock that writes  
data to its array (CLKA). The empty flag (EF) and almost-empty (AE) flag of the FIFO are two-stage  
synchronized to the port clock that reads data from its array.  
The SN74ABT3611 is characterized for operation from 0°C to 70°C.
