IDT723614 CMOS SYNCBIFIFO™ WITH BUS-MATCHING

AND BYTE SWAPPING 64 x 36 x 2

COMMERCIAL AND INDUSTRIAL

TEMPERATURE RANGES

This device is a clocked FIFO, which means each port employs a synchro-

nous interface. All data transfers through a port are gated to the LOW-to-HIGH

transition of a continuous (free-running) 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 controlled by a

synchronous interface.

The Full Flag (FFA, FFB) and Almost-Full flag (AFA, AFB) of a FIFO are

two-stage synchronized to the port clock that writes data to its array. The Empty

Flag (EFA, EFB) and Almost-Empty (AEA, AEB) flag of a FIFO are two stage

synchronized to the port clock that reads data from its array.

The IDT723614 is characterized for operation from 0°C to 70°C.
