If you understand an example, use it. 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? Post as a guest Name. Sign up using Facebook.

TobiasCrackz on Dec 14, The manufacturer is confident the part will be reliable at 70mA or less. Sign up using Email and Password. Putting 10nF load on a logic output will overload it. So i can omit using an ULN or similar device?
You can use the combination of an RC 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. Post them in the forum.

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.

It has hc40944 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. 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 ch4094 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 So should work for what I want I will have to look at how I am going to do it another time.
Does one SIPO chip clearly have more capabilities or easier to use than another, or are they all more-or-less equivalent functionality?
I’m drawing mA, the system runs for already 2 Months and the shift registers still work and don’t even get hot nor warm!!! 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.
Decoupling is on the supply to keep it stable against change. Remember slow here means slow compared to a few nanoseconds ie a microsecond or more. I order a heap of common anode displays by mistake and can’t use datashedt the MAX’s that I have due to the max being common cathode. Trying to get back into electronics after 15 years absence.

I also wouldn’t recommend going into production and selling things that exceed design specs. The shift registers shown are controlled with three lines: You would need a common-anode LED array, or have the anodes driven by transistors.
So 74HC is my choice. Next time try www.

It’s pretty much a latched shift register with constant current sinking outputs. Please do not even think of using the obsolete ULN2x03 series. TPIC is for when you need more output current. I need 12 channels, so plans to cascade 2 8 bit shift registers. So the question is, How critical is the application? Why for example, the “HC T ” version? Does one SIPO chip clearly have more capabilities or easier to use than another, or are they all more-or-less equivalent functionality? 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.
At high frequencies this will cook the pad driver on the chip. This kind of shift register can be used for driving LEDs and similar devices where short-term transient is irrelevant. TPIC is for when you need more output current.
I’d say twice the rated current is “pushing it”, but who knows But, there are manufacturing variations.
Do you have similar experience?
