Overview

TC74HC139AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC139AP, TC74HC139AF Dual 2-to-4 Line Decoder The TC74HC139A is a high speed CMOS 2-to-4 LINE DECODER/DEMULTIPLEXER fabricated with silicon gate C2MOS technology.

It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.

The active low enable input can be used for gating or it can be used as a data input for demultiplexing applications.

Key Features

  • High speed: tpd = 16 ns (typ. ) at VCC = 5 V.
  • Low power dissipation: ICC = 4 μA (max) at Ta = 25°C.
  • High noise immunity: VNIH = VNIL = 28% VCC (min).
  • Output drive capability: 10 LSTTL loads.
  • Symmetrical output impedance: |IOH| = IOL = 4 mA (min).
  • Balanced propagation dela.
