C to +85

C) is avail-

able, tested to military electrical specifications

DESCRIPTION:

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 ( ) 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 IDT7207 is fabricated using IDT’s high-speed CMOS

technology. It is designed for applications requiring asynchro-

nous 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.
