The manufacturer is confident the part will be reliable at 70mA or less. But if it does, you’ve exceeded the specs and you can’t complain. This is completely rated for the job you have.

Thank you for telling me about it. You hc094 use the combination of an RC low pass filter and a schmitt-trigger input to protect a datasehet signal from noise pickup, but clock to a shift register is a fast signal and must be prevented from multiple triggering. A serial-input, parallel-output SIPO chip is the best way to independently control lots of output dtaasheet using only a few pins on my microcontroller, right?

The load signal is level-sensitive, rather than edge sensitive, allowing the device to be used in a “transparent” mode, where bits from the input are immediately shown on the output. Why for example, the “HC T ” version?

I hadn’t looked at the 74HC, having always used the 74HC, but the 74HC looks like it has a couple of interesting differences: Standard logic inputs will undergo multiple transitions given a slowly varying input voltage.

I’m drawing mA, the system datasjeet for already 2 Months and the shift registers still work and don’t even get hot nor warm!!! Peculiar daatasheet of component! However, how is it possible to deduce from the datasheet of a part whether it is a “super-useful part that I should always keep a few on hand” vs a “specialized part to only buy as needed” vs a “completely obsolete part that there’s no point buying — instead part YYY is cheaper and better in every way”?

Some parts may fail just slightly over that, and some may handle more current “forever”.

I need 12 channels, so plans to cascade 2 8 bit shift registers. TPIC is for when you need datasjeet output current. Use of this latter output will greatly improve sample and hold margins when feeding the output of the device into another one; the former may be useful in some situations when feeding a device which is known to receive the clock before the data.

If you understand an example, use it. My application can’t tolerate change as it clocks! Please do not even think of using the obsolete ULN2x03 series. Home Questions Tags Users Unanswered. Electronics engineer by trade, software engineer by profession. I order a heap of common anode displays by mistake dtaasheet can’t use them the MAX’s that I have due to the max being common cathode.

Post them in the forum. MarkT Brattain Member Posts: Decoupling is on the supply to keep it stable against change. But if you’re building a bridge, you’d want to leave some safety margin and maybe put no more than a 50Lb load on the bolt. It may last forever. Hc40094 pretty much a latched shift register with constant current sinking outputs. They have more advanced chips as well; some with digital brightness control and even PWM settings for each channel.

But, there are manufacturing variations. How it effects practically in application? For example, the human eye can’t notice LED flickers shorter than 10 msec.

An analogy would be a bolt rated to hold Lbs. Assuming this thing isn’t going into space or used in a medical application, it might not be a big deal if it fails.

This kind of shift register can be used for driving LEDs and similar devices where hc094 transient is irrelevant. They all can be connected in the ” daisy-chain SPI ” configuration, right? Sign up using Email and Password.

You would need a common-anode LED array, or have the anodes driven by transistors. The specs don’t mean it’s going to burn-up instantly if you go to 71mA. Do you have similar experience? A serial-input, parallel-output SIPO chip is the best way to independently control lots of output pins using only a few pins on my microcontroller, right?

Does one SIPO chip clearly have more capabilities or easier to use than another, or are they all more-or-less equivalent functionality? They all can be connected in the ” daisy-chain SPI ” configuration, right? The shift registers shown are controlled with three lines: It should hold Lbs, and some may fail at Lbs and others may fail at Lbs. So i can omit using an ULN or similar device?

Trying to get back into electronics after 15 years absence. Next time try www. There have been times I would have used the 74HC’s asynchronous clear if the load signal was level-sensitive so that asserting clear and load simultaneously would clear the outputsand times I would have used a synchronous clear wire the cascade output to synchronous clear and synchronous load signals, and reduce communications requirement to two wiresbut I don’t think the signal will be missed on the 74HC Putting 10nF load on a logic output will overload it.

Transients occur because shift register is directly connected to output lines.
