DESCRIPTION:  
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-impedance state  
High-performance submicron CMOS technology  
Available in a 64-lead thin quad flatpack (TQFP/STQFP)
