DESCRIPTION:

The IDT72132/72142 are high-speed, low-power serial-toparallel FIFOs. These FIFOs are ideally suited to serial communications 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.

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 8, 9, 16-18, and 32-36 bit using Flexshift™ serial input 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 the 28-pin plastic DIP

• Industrial temperature range (-40oC to +85oC) is available, tested to military electrical specifications
