INFORMATION  
IDT7208  
CMOS ASYNCHRONOUS FIFO  
65,536 x 9  
Integrated Device Technology, Inc.  
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.  
FEATURES:  
• 65536 x 9 storage capacity  
• High-speed: 15ns access time  
• Low power consumption  
— Active: 660mW (max.)  
— Power-down: 44mW (max.)  
The device's 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.  
• 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  
The IDT7208 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.  
• High-performance CMOS technology  
• Industrial temperature range (-40oC to +85oC) is avail-  
able, tested to military electrical specifications  
DESCRIPTION:  
The IDT7208 is a monolithic dual-port memory buffer with
