Overview

TC74HC148AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC148AP, TC74HC148AF 8-to-3 Line Priority Encoder The TC74HC148A is a high speed CMOS 8-to-3 LINE ENCODER fabricated with silicon gate C2MOS technology.

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

All data inputs and outputs of these encoders are active at the low logic level.

Key Features

  • High speed: tpd = 15 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 74LS148 Pin Assignment TC74HC148AP TC74HC148.
