General Description

These multiplexers are digitally controlled analog switches

implemented in advanced silicon-gate CMOS technology.

These switches have low “on” resistance and low “off” leak-

VHC4051: This device connects together the outputs of 8

switches, thus achieving an 8 channel Multiplexer. The

binary code placed on the A, B, and C select lines deter-

mines which one of the eight switches is “on”, and con-

nects one of the eight inputs to the common output.
