Overview

TC74AC390P/F TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74AC390P, TC74AC390F Dual Decade Counter The TC74AC390 is an advanced high speed CMOS DUAL DECADE COUNTER 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 consists of two independent 4-bit counters, each composed of a divide-by-two and a divide-by-five counter.

Key Features

  • High speed: fmax = 160 MHz (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 74HC390 Pin Assignment . TC74AC390P TC74A.
