The DESCRIPTION about electronic components PCA9564
Do you know the applications about ic components pca9564?I find a website about the
information of electronic components pca9564.
DESCRIPTION
The electronic components PCA9564 is an integrated circuit designed in CMOS technology
that serves as an interface between most standard parallel-bus
microcontrollers/microprocessors and the serial I2C-bus and allows the parallel bus
system to communicate bi-directionally with the I2C-bus.
The electronic component PCA9564 can operate as a master or a slave and can be a
transmitter or receiver. Communication with the I2C-bus is carried out on a byte-wise
basis using interrupt or polled handshake.
The PCA9564 controls all the I2C-bus specific sequences, protocol, arbitration and
timing with no external timing element required. The PCA9564 is similar to the PCF8584
but operates at lower voltages and higher IC components frequencies. Other enhancements
requested by design engineers have also been incorporated.
Other famous electronic components contains lm358,lm317,ne555,lm324,lm339.

“Electronic Component” content introduction
For you recommend one said, The name of the book called” Electronic Component”, Main content abstract follows:
VDM Publishing House Ltd., 2010 - 158 pages
An electronic component is a basic electronic element usually packaged in a discrete form with two or more connecting leads or metallic pads. Components are intended to be connected together, usually by soldering to a printed circuit board, to create an electronic circuit with a particular function (for example an amplifier, radio receiver, or oscillator). Components may be packaged singly (resistor, capacitor, transistor, diode etc.) or in more or less complex groups as integrated circuits (operational amplifier, resistor array, logic gate etc.)
This is a very valuable and significance of the book about ic components industry, If you are engaged in the electronic components industry I suggest you buy. There are many popular type of recommendation such as lm358, lm317, NE555, lm324, LM339 and so on.

Someone asked me a question about ic components lm358,my own view
The electronic components lm358 or lm675 or lm675T only can have a minimum output of 5v and usually depend on the load connected. On the other hand, all 35 the lm358 connected in parallel can have a minimum output of 70mv when use as a unity gain buffer compare to lm675T. Furthermore, when connected in parallel it can have a more stable output to lm675 when driving heavy load. Oh ya, i also forget to mention how i connected those opamp in parallel. You can try it by connecting all the inverting input to the output of the opamp and all the output connected to a load. the non-inerting input all connected to a potentiometer so that all will read the same voltage value. After that, try adjust the potentiometer and observe the maximum output when connected to a 10ohm load. Repeat the step by connecting more lm358 opamp in parallel
If you want to learn more about the ic components knowledge,
recommend a few sites,such as tbf,hkin and hqew.net.
