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.
