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 thru P7, and inputs Q0 thru Q7, and indicates whether or not they are equal.

Key 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.
