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.
Some parts may fail just slightly over that, and some may handle more current “forever”.
For example, the human eye can’t notice LED flickers shorter than 10 msec. It’s pretty much a latched shift register with constant current sinking outputs. Decoupling is on the supply to keep it stable against change. You would need a common-anode LED array, or have the anodes driven by transistors.
Peculiar choice of component! I need 12 channels, so plans to cascade 2 8 bit shift registers.

Standard logic inputs will undergo multiple transitions given a slowly varying input voltage. One is ‘shift latch register’. 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. Datassheet should work for what I want I will have to look at how I am going to do it another time.
If you don’t understand an example, don’t use it. Does one SIPO chip clearly have more capabilities or easier to use than another, or are they all more-or-less equivalent functionality? 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. You can use the combination of an RC low pass filter and a schmitt-trigger input to protect a low-bandwidth signal from yc4094 pickup, but clock to a shift register is a fast signal and must be prevented from multiple triggering.
It may last forever. There have been times I would have used the ratasheet 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 So i can omit using an ULN or similar device?
I also wouldn’t recommend going into production and selling things that exceed design specs. Next time try www. 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? They all can be connected in the ” daisy-chain SPI ” configuration, right?
This is completely rated for the job you have. MarkT Brattain Member Posts: It also has 16 output channels. Email Required, but never shown. A serial-input, parallel-output SIPO chip is the best way to independently control lots of output pins using only a few pins on uc4094 microcontroller, right?
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 How it effects practically in application?
Remember slow here means slow compared to a few nanoseconds ie a microsecond or more. Yc4094, how is it possible to deduce from the datasheet of a part whether it is a “super-useful datasheft 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”?
Why for example, the “HC T ” version? Non-SMT versions are also available. Putting 10nF load on a logic output will overload it. Now with Unlimited Eagle board sizes! They have more dataasheet chips as well; some with digital brightness control and even PWM dafasheet for each channel.
