DESCRIPTION:
The IDT72103/72104 are high-speed Parallel-Serial FlFOs
to be used with high-performance systems for functions such
as serial communications, laser printer engine control and
local area networks.
A serial input, a serial output and two 9-bit parallel ports
make four modes of data transfer possible: serial-to-parallel,
parallel-to-serial, serial-to-serial, and parallel-to-parallel. The
IDT72103/72104 are expandable in both depth and width for
all of these operational configurations.
