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 toprevent data overflow and underflow and expansion logic toallow for unlimited expansion capability in both word size anddepth.

Data is toggled in and out of the device through the use ofthe Write (W) and Read (R) pins.

The devices 9-bit width provides a bit for a control or parityat the user’s option. It also features a Retransmit (RT) capa-bility that allows the read pointer to be reset to its initial positionwhen RT is pulsed LOW. A Half-Full Flag is available in thesingle device and width expansion modes.

The IDT7203/7204/7205/7206 are fabricated using IDT’shigh-speed CMOS technology. They are designed for appli-cations requiring asynchronous and simultaneous read/writesin multiprocessing, rate buffering, and other applications.Military grade product is manufactured in compliance withthe latest revision of MIL-STD-883, Class B.
