DESCRIPTION:

• 256 x 18-bit organization array (IDT72V205)

• 512 x 18-bit organization array (IDT72V215)

• 1,024 x 18-bit organization array (IDT72V225)

• 2,048 x 18-bit organization array (IDT72V235)

• 4,096 x 18-bit organization array (IDT72V245)

• 10 ns read/write cycle time

TheIDT72V205/72V215/72V225/72V235/72V245arefunctionallycom-

patibleversionsoftheIDT72205LB/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)

memorieswithclockedreadandwritecontrols. TheseFIFOsareapplicable

forawidevarietyofdatabufferingneeds,suchasopticaldiskcontrollers,Local

AreaNetworks(LANs),andinterprocessorcommunication.

• 5V input tolerant

• IDT Standard or First Word Fall Through timing

• Single or double register-buffered Empty and Full flags

• Easily expandable in depth and width

• Asynchronous or coincident Read and Write Clocks

• Asynchronous or synchronous programmable Almost-Empty

and Almost-Full flags with default settings

• Half-Full flag capability

• Output enable puts output data bus in high-impedanc state

• High-performance submicron CMOS technology

• Available in a 64-lead thin quad flatpack (TQFP/STQFP)

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