The 74HC/HCT4053 is a triple single-pole double-throw analog switch (3x $PDT) suitable for use inanalog or digital 2:1 multiplexer/demultiplexer applications. Each switch features a digital seleet input(Sn), two independent inputs/outputs (nY0 and nYl) and a common inputoutput (nZ). A digital enableinput (E) is common to all switches. When E is HlGH, the switches are turned off, lnputs include clampdiodes, This enables the use of current limiting resistors to interlace inputs to voltages in excess of Vcc.
