“This project describes the construction of an iPhone accessory which allows pictures of polarised light to be captured. It is based on previous work by David Prutchi which should be referred to for more details.”
Content for 74HC4052
The 74HC4052; 74HCT4052 is a dual single-pole quad-throw analog switch (2x SP4T) suitable for use in 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 switches. When 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.
