DESCRIPTION:
The IDT72401 and IDT72403 are asynchronous high-performance
First-ln/First-Outmemoriesorganized64wordsby4bits. TheIDT72403 also
hasanOutputEnable(OE)pin.TheFlFOsaccept4-bit dataatthedatainput
(D0-D3). The stored data stack up on a first-in/first-out basis.

Ready (IR) signal acts like a flag to indicate when the input is ready for new
data (IR = HIGH) or to signal when the FIFO is full (IR = LOW). The IR signal
canalsobeusedtocascademultipledevicestogether.TheOutputReady(OR)
signal is a flag to indicate that the output remains valid data (OR = HIGH) or
to indicate that the FIFO is empty (OR = LOW). The OR can also be used to
cascademultipledevicestogether.
