The IDT71V2557/59 contain address, data-in and control signal  
registers.Theoutputsareflow-through(nooutputdataregister).Output  
enable is the only asynchronous signal and can be used to disable the  
outputsatanygiventime.  
A Clock Enable (CEN) pin allows operation of the IDT71V2557/59  
to be suspended as long as necessary. All synchronous inputs are  
ignored when (CEN) is high and the internal device registers will hold  
their previous values.  
There are three chip enable pins (CE1, CE2, CE2) that allow the  
usertodeselectthedevicewhendesired.Ifanyoneofthesethreeisnot

The IDT71V2557/59 have an on-chip burst counter. In the burst  
mode, the IDT71V2557/59 can provide four cycles of data for a single  
address presented to the SRAM. The order of the burst sequence is  
defined by the LBO input pin. The LBO pin selects between linear and  
interleaved burst sequence. The ADV/LD signal is used to load a new  
external address (ADV/LD = LOW) or increment the internal burst  
counter (ADV/LD = HIGH).
