TC74AC521FW Overview
It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. It pares two 8-bit binary or BCD words applied inputs P0~P7, and inputs Q0~Q7, and indicates whether or not they are equal. A signal active low enable is provided to facilitate cascading of several packages to pare of words greater than 8 bits.
TC74AC521FW Key Features
