DESCRIPTION:

load and empty data on a first-in/first-out basis. These devices are functional

and compatible to two IDT7200/7201/7202/7203/7204/7205 FIFOs in a single

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

underflow and expansion logic to allow for unlimited expansion capability in both

word size and depth.

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.

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

error checking. It also features a Retransmit (RT) capability that allows for reset

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.

They are designed for those applications requiring asynchronous and simul-

taneous read/writes in multiprocessing and rate buffer applications.

The IDT7280/7281/7282/7283/7284/7285 are dual-FIFO memories that

The reads and writes are internally sequential through the use of ring pointers,

The devices utilize a 9-bit wide data array to allow for control and parity bits

These FIFOs are fabricated using IDT’s high-speed CMOS technology.
