DESCRIPTION:
The IDT72413 is a 64 x 5, high-speed First-In/First-Out (FIFO) that loads
and empties data on a first-in-first-out basis. It is expandable in bit width. All speed
versions are cascad-able in depth.
The FIFO has a Half-Full Flag, which signals when it has 32 or more words
in memory. The Almost-Full/Empty Flag is active when there are 56 or more
words in memory or when there are 8 or less words in memory.
This device is pin and functionally compatible to the MMI67413. It operates
at a shift rate of 45MHz. This makes it ideal for use in high-speed data buffering
applications. This FIFO can be used as a rate buffer, between two digital systems
of varying data rates, in high-speed tape drivers, hard disk controllers, data
communications controllers anD graphics controllers.
The IDT72413 is fabricated using IDTs high-performance CMOS process.
This process maintains the speed and high output drive capability of TTL circuits
in low-power CMOS.
