Description
• Complementary Data Outputs
• Buffered Inputs and Outputs
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).
