DESCRIPTION:

The IDT72105/72115/72125s are very high-speed, lowpower,dedicated, parallel-to-serial FIFOs. These FIFOs possess a 16-bit parallel input port and a serial output port with 256, 512 and 1K word depths, respectively.

The ability to buffer wide word widths (x16) make these FIFOs ideal for laser printers, FAX machines, local area networks (LANs), video storage and disk/tape controller applications.

FEATURES:

? 25ns parallel port access time, 35ns cycle time

? 45MHz 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 (-40oC to +85oC) is available, tested to military electrical specifications
