TC74AC521P 8-Bit Equality Comparator

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 maint.

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 transmission lines.
• Balanced propagation delays: tpLH ∼− tpHL
• Wide operating voltage range: VCC (opr) = 2 to 5.5 V
• Pin and function compatible with 74F521 Pin Assignment TC74AC521P TC74AC521F Weight DIP20-P-300-2.54A SOP20-P-300-1.27A : 1.30 g (typ.) : 0.22 g (typ.) Start of commercial production 1989-11 1 2014-03-01 IEC Logic Symbol Truth Table .
