Overview

Description

The 72125 is a 1K x 16 dedicated, parallel-to-serial FIFOs. The ability to buffer wide word widths (x16) make this FIFO ideal for laser printers, FAX machines, local area networks (LANS), video storage and disk/tape controller applications. Expansion in width and depth can be achieved using multiple chips. IDT's unique serial expansion logic makes this possible using a minimum of pins.

Features

  • 25ns parallel port access time, 35ns cycle time
  • 50MHz serial output shift rate
  • Wide x16 organization offering easy expansion
  • Low power consumption (50mA typical)
  • Least/Most Significant Bit first read selected by asserting the FL/DIR pin
  • Four memory status flags: Empty, Full, Half-Full, and Almost-Empty/Almost-Full
  • Dual-Port zero fall-through architecture
  • Available in 28-pin 300 mil plastic DIP and 28-pin SOIC
  • Industrial temperature range (–40C to +85C)
