Description
• Buffered Inputs
• Exceeds 2kV ESD Protection MIL-STD-883, Method
3015
The CD74AC151 and CD74ACT151 are 8-input digital multiplexers that utilize the Harris Advanced CMOS Logic technology. They have three binary control inputs (S0, S1, and
S2) and an active-LOW Enable (E) input. The three binary
inputs select 1 of 8 channels. The output is both inverting (Y)
and non-inverting (Y).
