DESCRIPTION:

The IDT7203/7204/7205/7206 are dual-port memory buff-

ers with internal pointers that load and empty data on a first-

in/first-out basis. The device uses 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.

Data is toggled in and out of the device through the use of

the Write ( ) and Read ( ) pins.

The devices 9-bit width provides a bit for a control or parity

at the user’s option. It also features a Retransmit ( ) capa-

bility that allows the read pointer to be reset to its initial position

when

is pulsed LOW. A Half-Full Flag is available in the

single device and width expansion modes.

The IDT7203/7204/7205/7206 are fabricated using IDT’s

high-speed CMOS technology. They are designed for appli-

cations requiring asynchronous and simultaneous read/writes

in multiprocessing, rate buffering, and other applications.

Military grade product is manufactured in compliance with

the latest revision of MIL-STD-883, Class B.
