Overview

www.DataSheet4U.com TC74AC257,258P/F/FN TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74AC257P,TC74AC257F,TC74AC257FN TC74AC258P,TC74AC258F,TC74AC258FN TC74AC257P/F/FN 2-Channel Multiplexer (3-state) TC74AC258P/F/FN 2-Channel Multiplexer (3-state, inverting) The TC74AC257 and TC74AC258 are advanced high speed CMOS MULTIPLEXERs fabricated with silicon gate and double-layer metal wiring C2MOS technology.

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

Each is composed of four independent 2-channel multiplexers with common SELECT and OUTPUT ENABLE ( OE ).

Key Features

  • High speed: tpd = 3.6 ns (typ. ) at VCC = 5 V DataSheet4U. com 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) = 2~5.5 V Pin and function compatible with 74F257/258 TC74AC257FN, T.
