I will probably use a timer instead. Drop me a message!

Other cd datasheet that bothers me is why it is so low? Most darlingtons have a gain over so even with under 1mA base drive you will easily be able to handle a 5A load. Typical parts will do much better.

It would be more intuitive if, instead cd datasheet, currents IoL and Ioh, let the reader think in terms of resistor and use ohm values.

The output is basically two FETs in series.

If you look at the cd datasheet slope of those points i. Ok, now I have some sort daatsheet understanding. May 31, Cd datasheet shorting the output, is the power dissipation in spec. In fact, this is what is done in their doc about standard B-series output drive. In theory, there is cd datasheet difference between theory and practice.


SeanB Super Cd datasheet Posts: In a logic family, such definitions may not be in every individual datasheet, but in a common family reference paper or application note. With this single resistor view, it should be easy to understand 1.

T3sl4co1l Super Contributor Posts: But, in practice, there is. Hero Super Contributor Posts: Whether datasheet datasheet current is positive or negative depends on the datashewt of reference.

Please login or register. If the output pin is taken as the reference then any current flowing out of it assuming cd datasheet current flow will be negative. Dqtasheet for sign, datasheets usually define that positive current is entering the pin, and negative is leaving. According to the data sheet the high level current at 5v will be cd datasheet If you want more current forget cd datasheet darlington and use a logic level MOSFET instead, lower on state power dissipation from the sub ohm on resistance, as opposed cd datasheet the darlington which will always have 1V2 to 2V drop across when fully on, irrespective of the current.


You can roughly assume that the output pin characteristic resembles: The guaranteed limits they put on performance are used to fix hard points in the V-I range that cd datasheet must meet.

Input pins can be modeled the same way, but without active drive obviouslydominant capacitance, and a softer diode clamp behavior. No idea why current is negative when the output is high though.

There was an error while thanking. I think the key point for beginners is that this is CMOS. Did you miss your activation email?
