TC74AC521P/F TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74AC521P, TC74AC521F 8-Bit Equality Comparator The TC74AC521 is an advanced high speed CMOS 8-BIT DIGITAL COMPARATOR fabricated with silicon gate and double-layer metal wiring C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. It compares two 8-bit binary or BCD words applied inputs P0 thru P7, and inputs Q0 thru Q7, and indicates whether or not they are equal. A signal active low enable is provided to facilitate cascading of several packages to compare of words greater than 8 bits. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features • High speed: tpd = 6.
