The 72403 is an asynchronous 64 x 4 First-ln/First-Out memory with an output enable pin. Reading and writing operations are completely asynchronous allowing the FIFO to be used as a buffer between two digital machines of widely varying operating frequencies. The 45MHz speed makes this FlFO ideal for high speed communication and controller applications.

Features

  • RAM-based FIFO with low fall-through time
  • Low-power consumption
  • Maximum shift rate — 45MHz
  • High data output drive capability
  • Fully expandable by bit width
  • Fully expandable by word depth
  • MlL-STD-883, Class B in 16 pin Cerdip package
