8-Channel Multiplexer

The TC74ACT151 is an advanced high speed CMOS 8-CHANNEL MULTIPLEXER fabricated with silicon gate and double-layer metal wiring C2MOS technology.

It achieves 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. The inputs are compatible with TTL, NMOS and CMOS output voltage levels.

Features

• High speed: tpd = 7.1 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 74F151
