The 65,636 x 9 organization (IDT7208) device uses Full and Empty flags to prevent data overflow and underflow and High-speed: 12ns access time expansion logic to allow for unlimited expansion capability in both word size and Low power consumption depth. Active: 660mW (max.) Data is toggled in and out of the device through the use of the Write (W) and Power-down: 44mW (max.) Read (R) pins. Asynchronous and simultaneous read and write The device s 9-bit width provides a bit for a control or parity at the users Fully expandable in both word depth and width option. It also features a Retransmit (RT) capability that allows the read pointer 720x family is pin and functionally compatible from 256 x 9 to 64k x 9 to be reset to its initial position when RT is pulsed LOW. A Half-Full Flag is Status Flags: Empty, Half-Full, Full available in the single device and width expansion modes. Retransmit capability These FIFOs are fabricated using high-speed CMOS technology. They High-performance CMOS technology are designed for applications requiring asynchronous and simultaneous read/ Military product compliant to MIL-STD-883, Class B writes in multiprocessing, rate buffering and other applications. Standard Military Drawing for 5962-88669 (IDT7203), 5962-89567 Military grade product is manufactured in compliance with MIL-STD-883, (IDT7203), and 5962-89568 (IDT7204) are listed on this function Class B.
