DESCRIPTION:

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.

FEATURES:

• 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) is available, tested to military electrical specifications
