DESCRIPTION:
The IDT7280/7281/7282/7283/7284/7285 are dual-FIFO memories that
load and empty data on a first-in/first-out basis. These devices are functional
andcompatibletotwoIDT7200/7201/7202/7203/7204/7205FIFOsinasingle
package with all associated control, data, and flag lines assigned to separate
pins. The devices use Full and Empty flags to prevent data overflow and
underflowandexpansionlogictoallowforunlimitedexpansioncapabilityinboth
word size and depth.
Thereadsandwritesareinternallysequentialthroughtheuseofringpointers,
with no address information required to load and unload data. Data is toggled
in and out of the devices through the use of the Write (
W) and Read (R) pins.
The devices utilize a 9-bit wide data array to allow for control and parity bits
at the user’s option. This feature is especially useful in data communications
applications where it is necessary to use a parity bit for transmission/reception
errorchecking.ItalsofeaturesaRetransmit(

of the read pointer to its initial position when
RT is pulsed LOW to allow for
retransmission from the beginning of data. A Half-Full Flag is available in the
single device mode and width expansion modes.
These FIFOs are fabricated using IDT’s high-speed CMOS technology.
They are designed for those applications requiring asynchronous and simul-
taneous read/writes in multiprocessing and rate buffer applications.
