CMOS PARALLEL-TO-SERIAL FIFO

2,048 x 9 and 4,096 x 9

FEATURES:

•

IDT72131

IDT72141

DESCRIPTION:

The IDT72131/72141 are high-speed, low power parallel-to-serial FIFOs.

These FIFOs are ideally suited to serial communications applications, tape/

disk controllers, and local area networks (LANs). These devices 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.

These devices can also be directly connected for depth expansion.

Five flags are provided to monitor the FIFO. The full and empty flags

prevent any FIFO data overflow or underflow conditions. The Almost-Full

(7/8), Half-Full, and Almost-Empty (1/8) flags signal memory utilization

within the FIFO.

The IDT72131/72141 is fabricated using IDTs high-speed submicron

CMOS technology.

35ns parallel port access time, 45ns cycle time

50MHz serial port shift rate

Expandable in depth and width with no external components

Programmable word lengths including 7-9, 16-18, 32-36 bit using

Flexishift™ serial output without using any additional components

Multiple status flags: Full, Almost-Full (1/8 from full), Half-Full,

Almost- Empty (1/8 from empty), and Empty

Asynchronous and simultaneous read and write operations

Dual-Port zero fall-through architecture

Retransmit capability in single device mode

Produced with high-performance, low power CMOS technology

Available in 28-pin plastic DIP

Industrial temperature range (–40°C to +85°C)
