DESCRIPTION:

patible versions of the IDT72205LB/72215LB/72225LB/72235LB/72245LB,

designed to run off a 3.3V supply for exceptionally low power consumption.

These devices are very high-speed, low-power First-In, First-Out (FIFO)

memories with clocked read and write controls. These FIFOs are applicable

for a wide variety of data buffering needs, such as optical disk controllers, Local

Area Networks (LANs), and interprocessor communication.

by a free-running clock (WCLK), and an input enable pin (WEN). Data is read

into the synchronous FIFO on every clock when WEN is asserted. The output

port is controlled by another clock pin (RCLK) and another enable pin (REN).

The Read Clock(RCLK) can be tied to the Write Clock for single clock operation

or the two clocks can run asynchronous of one another for dual-clock operation.

An Output Enable pin (OE) is provided on the read port for three-state control

of the output.

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

Green parts available, see ordering information

The IDT72V205/72V215/72V225/72V235/72V245 are functionally com-

These FIFOs have 18-bit input and output ports. The input port is controlled
