Nexperia 74HC4052/74HCT4052 Dual Single-Pole Quad-Throw (SP4T) Analog Switch is suitable for analog or digital 4:1 multiplexer/demultiplexer applications. Each switch features four independent inputs/outputs (nY0, nY1, nY2, and nY3) and a common input/output (nZ). A digital enable input (E) and two digital select inputs (S0 and S1) are common to both Nexperia switches. When E is HIGH, the switches are turned off. Inputs include clamp diodes. This feature enables the use of current-limiting resistors to interface inputs to voltages above VCC.
