These FIFOs have 9-bit input and output ports. The input port is

controlled by a free-running clock (WCLK), and two Write Enable pins

(WEN1,WEN2). DataiswrittenintotheSynchronousFIFOoneveryrising

clock edge when the Write Enable pins are asserted. The output port is

controlledbyanotherclockpin(RCLK)andtwoReadEnable pins (REN1,

• 10 ns read/write cycle time

• 5V input tolerant

• Read and Write clocks can be independent

• Dual-Ported zero fall-through time architecture

• Empty and Full Flags signal FIFO status

• Programmable Almost-Empty and Almost-Full flags can be set to REN2). The Read Clock can be tied to the Write Clock for single clock

• Programmable Almost-Empty and Almost-Full flags default to

Empty+7, and Full-7, respectively

• Output Enable puts output data bus in high-impedance state

• Advanced submicron CMOS technology

• Available in 32-pin plastic leaded chip carrier (PLCC) and 32-pin

plastic Thin Quad FlatPack (TQFP)

The Synchronous FIFOs have twofixedflags, Empty(EF)andFull(FF).

Two programmable flags, Almost-Empty (PAE) and Almost-Full (PAF), are

provided for improved system control. The programmable flags default to

• Industrial temperature range (–40°C to +85°C) is available

These FIFOs are fabricated using IDT's high-speed submicron CMOS

technology.
