DESCRIPTION The M54HC251 is an high speed CMOS 8-CHANNEL MULTIPLEXER (3-STATE) fabricated with silicon gate C2MOS technology.

This Multiplexer features both true (Y) and complement (W) outputs as well as STROBE input. When the STROBE is high, both outputs are in the high impedance state. When enabled, address information on the data select inputs determines which data input is routed to Y and W. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
