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.
