Overview

TC74HC157,158AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC157AP, TC74HC157AF TC74HC158AP, TC74HC158AF TC74HC157AP/AF TC74HC158AP/AF Quad 2-Channel Multiplexer Quad 2-Channel Multiplexer (inverting) TC74HC157AP, TC74HC158AP The TC74HC157A and TC74HC158A are high speed CMOS 2-CHANNEL MULTIPLEXERs fabricated with silicon gate C2MOS technology.

They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.

The TC74HC158A is an inverting multiplexer while the TC74HC157A is a non-inverting.

Key Features

  • High speed: tpd = 10 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 delays: tpLH ∼.
  • tpHL.
  • Wide operating voltage range: VCC (opr) = 2 to 6 V.
  • Pin and function compatible with 74LS157/158 TC74HC157AF, TC74HC158AF Weight.
