The \x92FCT480T devices are high-speed, dual, 8-bit parity generators/checkers. Each parity generator/checker accepts eight data bits and one parity bit as inputs, and generates a sum and parity-error (ERROR\) output. These devices can be used in odd-parity systems. ERROR\ is an open-drain output designed for easy expansion of the word width by a wired-OR connection of several \x92FCT480T devices. Because no additional logic is needed, the parity-generation or parity-checking times remain the same as for an individual \x92FCT480T device.

These devices are fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
