1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

The IDT7207 is a monolithic dual-port memory buffer 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 ( W) and Read ( R) pins.

The devices 9-bit width provides a bit for a control or parity at the user's option. It also features a Retransmit (RT) capability that allows the read pointer to be reset to its initial position when RT is pulsed LOW. A Half-Full Flag is available in the single device and width expansion modes.

The IDT7207 is fabricated using IDT's high-speed CMOS technology. It is designed for applications requiring asynchronous and simultaneous read/writes in multiprocessing, rate buffering, and other applications.

Military grade product of the IDT7207 is manufactured in compliance with the latest revision of MIL-STD-883, Class B.
