74HC4052D,653

74HC4052D,653 is a dual 4-channel analogue multiplexer/demultiplexer. This is a dual single-pole quad-throw analogue switch (2 × SP4T) suitable for use in analogue 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 active low (E) and two digital select inputs (S0 and S1) are common to both switches. When (active low)E is HIGH, the switches are turned off. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. Typical applications include analogue multiplexing and demultiplexing, digital multiplexing and demultiplexing and signal gating applications.
