Overview
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~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 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.
4 ns (typ.
) at VCC = 5 V • Low power dissipation: ICC = 8 μA (max) at Ta = 25°C • High noise immunity: VNIH = VNIL = 28% VCC (min) • Symmetrical output impedance: |IOH| = IOL = 24 mA (min) Capability of driving 50 Ω t...
