Overview

TC74ACT257P/F TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74ACT257P, TC74ACT257F 2-Channel Multiplexer (3-state) The TC74ACT257 is an advanced high speed CMOS MULTIPLEXER fabricated with silicon gate and double-layer metal wiring C2MOS technology.

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

This device may be used as a level converter for interfacing TTL or NMOS to High Speed CMOS.

Key Features

  • High speed: tpd = 5.8 ns (typ. ) at VCC = 5 V.
  • Low power dissipation: ICC = 8 μA (max) at Ta = 25°C.
  • Compatible with TTL outputs: VIL = 0.8 V (max) VIH = 2.0 V (min).
  • Symmetrical output impedance: |IOH| = IOL = 24 mA (min) Capability of driving 50 Ω transmission lines.
  • Balanced propagation delays: tpLH ∼.
  • tpHL.
  • Pin and function compatible with 74F257 Pin Assignment TC74ACT257P TC74ACT257F Weight DIP16-P-300-2.54A SOP16-P-300-1.27A.
