But, there are manufacturing variations. So should work for what I want I will have to look at how I am going to do it another time. They have more advanced chips as datashee some with digital brightness control and even PWM settings for each channel. They all can be connected in the ” daisy-chain SPI ” configuration, right?

Peculiar choice of component! A serial-input, parallel-output SIPO chip is the best way vatasheet independently control lots of output dahasheet using only a few pins on my microcontroller, right? I hadn’t looked at the 74HC, having always used hf4094 74HC, but the 74HC looks like it has a couple of interesting differences: 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.

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.

Post them in the forum. Standard logic inputs will undergo multiple transitions given a slowly varying input voltage. A serial-input, parallel-output SIPO chip is the datahseet way to independently control lots of output pins using only a few pins on my microcontroller, right? It may last forever.

But if it does, you’ve exceeded the specs and you can’t complain. Putting 10nF load on a logic output will overload it. The shift registers shown are controlled with three lines: Decoupling is on the supply to keep it stable against change. 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 Sign up using Facebook.

It’s pretty much a latched shift register with constant current sinking outputs. Does one SIPO chip clearly have more capabilities or easier to use than another, or are they all more-or-less equivalent functionality? I’d say twice the rated current is “pushing it”, but who knows Please don’t PM me with technical questions. Now with Unlimited Eagle board sizes!

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. I hadn’t looked at the 74HC, having always used the 74HC, but the 74HC looks like it has a couple of interesting differences: TPIC is for when you need more output current.

It has a gc4094 output which triggers on the same clock edge as the input, as well as a cascading output which is delayed by half a clock.

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 You can use the combination of an Datasheeet low pass filter and a schmitt-trigger input to protect a low-bandwidth signal from noise pickup, but clock to a shift register is a fast signal and must be prevented from multiple triggering.

The 74HC does not have the asynchronous clear function of the 74HC Post as a guest Name. So 74HC is my choice. Non-SMT versions are also available.

This kind of shift register can be used for driving LEDs and similar devices where short-term transient is irrelevant. Sign up or log in Sign up using Google. 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 hx4094 in some situations when feeding a device which is known to receive the clock before the data.
