IDT72103 Description
The IDT72103/72104 are high-speed Parallel-Serial FlFOs to be used with high-performance systems for functions such as serial munications, 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.
