Description: The 74ACT151 is a high-speed 8-input multiplexer with 3-state outputs.

Features:

High-speed performance: tPD = 8.5 ns (typical) at VCC = 5 V
Low power dissipation: ICC = 4 μA (max)
High noise immunity: VNIH = VNIL = 28% VCC (min)
Outputs source/sink 24 mA
Outputs can be connected to other open-collector outputs to implement active-low wired-OR or active-high wired-AND functions
Input clamp diodes
Balanced propagation delays
Latchup performance exceeds 250 mA per JESD 78, Class II

Applications:

Multiplexers
Data selectors/multiplexers
Address selectors/decoders
Bus-oriented systems
Memory systems
High-speed logic systems
High-speed switching systems(For reference only)
