The IDT72131/72141 are high-speed, low power parallelto-serial FIFOs. These FIFOs are ideally suited to serial communications applications, tape/disk controllers, and local area networks (LANs). The IDT72131/72141 can be configured with the IDTs serial-to-parallel FIFOs (IDT72132/72142) for bidirectional serial data buffering. The FIFO has a 9-bit parallel input port and a serial output port. Wider and deeper parallel-to-serial data buffers can be built using multiple IDT72131/72141 chips. IDTs unique Flexishift serial expansion logic (SOX, NR) makes width expansion possible with no additional components. These FIFOs will expand to a variety of word widths including 8, 9, 16, and 32 bits. The IDT72131/141 can also be directly connected for depth expansion. |
