  • TTL compatible
  • Package: 28 pin R AD-PAK® flat package DESCRIPTION: Maxwell Technologies’ 7206F high speed FIFO microcircuit features a greater than 100 krad (Si) total dose tolerance, depending upon space mission. It is organized such that the data is read in the same sequential order that it was written. Full and Empty flags are provi ded to prevent overflow and underflow. The expansion logic allows unlimited expansion capability in work size and depth with no timing penalties. Twin address pointers automatically generate internal read and write addresses, and automatically increment with the write and read pin. The 7206F 9-bits wide data are used in data communications applications where a parity bit for error checking is necessary. The retr ansmit capability allows the read pointer to be reset to its initial position without affecting the write pointer. Maxwell Technologies' patented R AD-PAK® packaging technol- ogy incorporates radiation shie lding in the microcircuit pack- age. It eliminates the need for box shielding while providing the required radiation shielding fo r a lifetime in orbit or space mission. In a GEO orbit, R AD-PAK provides greater than 100 krad (Si) radiation dose toleranc e. This product is available with screening up to Class S. Logic Diagram
