The 74LV4053 is a triple single-pole double-throw (SPDT) analog switch, suitable for use in 2:1 multiplexer/demultiplexer applications. Each switch features a digital select input (Sn), two independent inputs/outputs (Y0 and Y1) and a common input/output (Z). A digital enable input (E) is common to all switches. When E is HIGH, the switches are turned off.

Digital inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess VCC.
