DESCRIPTION:

• First-In/First-Out Dual-Port memory

• 2048 x 9 organization (IDT7203)

• 4096 x 9 organization (IDT7204)

• 8192 x 9 organization (IDT7205)

• 16384 x 9 organization (IDT7206)

• High-speed: 12ns access time

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.

• Low power consumption

— Active: 770mW (max.)

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

the Write (W) and Read (R) pins.

— Power-down: 44mW (max.)

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

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

bilitythatallowsthereadpointertoberesettoitsinitialposition

when RT 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-

cationsrequiringasynchronousandsimultaneousread/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.

• Asynchronous and simultaneous read and write

• Fully expandable in both word depth and width

• Pin and functionally compatible with IDT720X family

• Status Flags: Empty, Half-Full, Full

• Retransmit capability

• High-performance CMOS technology

• Military product compliant to MIL-STD-883, Class B

• Standard Military Drawing for #5962-88669 (IDT7203),

5962-89567 (IDT7203), and 5962-89568 (IDT7204) are

listed on this function

• Industrial temperature range (-40^oC to +85^oC) is avail-

able, tested to military electrical specifications
