DESCRIPTION:
versions of the IDT723624/723634/723644, designed to run off a 3.3V supply
for exceptionally low-power consumption. These devices are monolithic, high-
speed, low-power, CMOS bidirectional synchronous (clocked) FIFO memory
which supports clock frequencies up to 100 MHz and has read access times as

be input and output in 36-bit, 18-bit, or 9-bit formats with a choice of Big- or Little-
Endian configurations.
employs a synchronous interface. All data transfers through a port are gated
to the LOW-to-HIGH transition of a port clock by enable signals. The clocks for
These devices are a synchronous (clocked) FIFO, meaning each port
