IDT71V547  
SRAM with ZBT™ Feature, Burst  
Counter and Flow-Through Outputs  
Features  
128K x 36 memory configuration, flow-through outputs  
TheIDT71V547containsaddress,data-inandcontrolsignalregisters.  
Theoutputsareflow-through(nooutputdataregister).Outputenableis  
theonlyasynchronoussignalandcanbeusedtodisabletheoutputsat  
anygiventime.  
Supports high performance system speed - 95 MHz  
(8ns Clock-to-Data Access)  
ZBTTM Feature - No dead cycles between write and read  
cycles  
A Clock Enable (CEN) pin allows operation of the IDT71V547 to  
be suspended as long as necessary. All synchronous inputs are  
ignored when CENis high and the internal device registers will hold  
their previous values.
