Ic components DG408 and DG409 description introduction
The electronic components DG408 and electronic component DG409 feature lower signal ON resistance (<100Ω) and faster switch transition time (tTRANS < 250ns) compared to the DG508A or DG509A. Charge injection has been reduced, simplifying sample and hold applications.
The improvements in the DG408 series are made possible by using a high-voltage silicon-gate process. An epitaxial layer prevents the latch-up associated with older CMOS
technologies. Power supplies may be single-ended from +5V to +34V, or split from ±5V to ±20V.
The analog switches are bilateral, equally matched for AC or bidirectional signals. The ON resistance variation with analog signals is quite low over a ±5V analog input range.
Hqew.net provide you with the national ic components lm358,lm317,ne555,lm324,lm339.

The detailed description about electronic components lm358
The top ic components LM158 series consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.
Application areas include transducer amplifiers, dc gain blocks and all the conventional op amp circuits which now can be more easily implemented in single power supply systems. For example, the LM158 series can be directly operated off of the standard +5V power supply voltage which is used in digital systems and will easily provide the required interface electronics without requiring the additional ±15V power supplies.

How to solve thirty five LM358 connect in parallel
I have a question about electronic components LM358,thirty five LM358 connect in
parallel.
Any have try before use an ic components LM358 as a voltage follower/unity gain opamp to drive a
10ohm load? it is not working right? However, it seem that it will works if connected
thirty five LM358 in parallel driving the 10ohm load, the output voltage can be adjust
from the range of 0 to 10v. Any have done this experiment before kindly leave a comment
or feedback because it is working but i have no idea will such connection spoil the IC
or not.
Does anyone know how to solve the problem?
