CD54HC151 - High-Speed CMOS Logic 8-Input Multiplexer

The ’HC151 and ’HCT151 are single 8-channel digital multiplexers having three binary control inputs, S0, S1 and S2 and an active low enable (E)\ input. The three binary signals select 1 of 8 channels. Outputs are both inverting (Y\) and non-inverting (Y).
