IDT72142 Overview
The IDT72132/72142 are high-speed, low-power serial-toparallel FIFOs. These FIFOs are ideally suited to serial munications applications, tape/disk controllers, and local area networks (LANs). The IDT72132/72142 can be configured with the IDTs parallel-to-serial FIFOs (IDT72131/72141) for bidirectional serial data buffering.
