The load signal is level-sensitive, adtasheet than edge sensitive, allowing the device to datashdet used in a “transparent” mode, where bits from the input are immediately shown on the output.

Assuming this thing isn’t going into space or used in a medical application, it might not be a big deal if it fails. At high frequencies this will cook the pad driver on the chip. I need 12 channels, so plans to cascade 2 8 bit shift registers. I hadn’t looked at the 74HC, having always used the 74HC, but the 74HC looks like it has a couple of interesting differences:. I also wouldn’t recommend going into production and selling things that exceed design specs.

It should hold Lbs, and some may fail hc4049 Lbs and others may fail at Lbs.

Please do not even think xatasheet using the obsolete ULN2x03 series. But if it does, you’ve exceeded the specs and you can’t complain. Trying to get back into electronics after 15 years absence.

This is completely rated for the job you have. It has a cascading output which triggers on the same clock edge as the input, as well as a cascading output which is delayed by half a clock. So should work for what Datasheey want I will have to look at how I am going to do it another time.

If I only have room for one kind of SIPO chip in my box of “electronics components I always have on hand”which one should it be? 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?

Why for example, the “HC T ” version? Now with Unlimited Eagle board sizes! MarkT on Dec 12, If you understand an example, use it. Non-SMT versions are also available. Standard logic inputs will undergo multiple transitions given a slowly varying input voltage. You would need a common-anode LED array, or have the anodes driven by transistors.

Transients occur because shift register is directly connected to output lines. This kind of shift register can be used for driving LEDs and similar devices where short-term transient is irrelevant. They have more advanced chips as well; some with digital brightness control and even PWM settings for each channel. Sign up or log in Sign up using Google. Peculiar choice of component! 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.

Selling HCB, HCBE, HC with HCB, HCBE, HC Datasheet PDF of these parts.

It also has 16 output channels. Home Questions Tags Users Unanswered. The 74HC does not have the asynchronous clear function of the 74HC My application can’t tolerate change as it clocks!

Please don’t PM me with technical questions.

They all can be connected in the ” daisy-chain SPI ” configuration, right?

The 74HC does not have the asynchronous clear function of the daatasheet There have been dagasheet 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 TobiasCrackz on Dec 14, Thank you for telling me about it.

If you hc44094 understand an example, don’t use it. The specs don’t mean it’s going to burn-up instantly if you go to 71mA. 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 datashfet would clear the outputsand times I would have used a synchronous clear wire the cascade output to synchronous clear and datasheeet load signals, and reduce communications requirement to two wiresbut I don’t think the signal will be missed on the 74HC TPIC is for when you need more output current.

So the question is, How critical is the application? So i can omit using an ULN or similar device?
