The second function is to act as a buffer that has output enable, in order to control SPI output from a 74HC chip.

Any help would be greatly appreciated.

The waveform looks very good with hardly any delay when compared to the original trace. However, this feature comes at a price: When the chip that generates the input runs at a lower Vcc, HCT is often better.

Each buffer has a separate output enable pin that must be high to activate the output. Heat sinks, Part 2: This time I wired the part to both 3. Fill out the form on our contact us page and we will get back to you. Dynamic pricing is based on the idea of giving you best value for money. The reason for this behavior is that the breadboard traces between the resistors and even oscilloscope probes have a 7h4ct125n amount of capacitance, which generates a low-pass filter that starts to distort or dampen the high frequency signals.

Lowering the resistor values to 1k fixes this problem, but still 74hct125h shape of transition is a bit round and it already draws around 1mA of current: A schematic would be helpful. My testing also showed that in addition to the voltage characteristics, the propagation delay is a critical attribute to consider in any signalling applications above kHz.

Simple low to high conversion: Distorted Sine output from Transformer 8. Alternative component to BEL transistor 2. Synthesized tuning, Part 2: Home Questions Tags Users Unanswered. I would like to know the performance limitations of this simple setup. With B and my particular setup, the delay was ns nanoseconds — my Picoscope software allows me to measure that easily see the image.

Why is there minimum line value MLV? At ns, the propagation delay limits the use of this circuit to low frequency signal switching.

When the chip that generates the input runs at the same level as the logic chip, preferrably use a HC but an HCT will still work. This 74hct125h the output will sink current, something it should be better at of course, the LED will now light when output is LOW…. Wouter van Ooijen So I had it backwards.

I could actually also try the zener diode method, too. Dec 248: We can ship to more than countries using our UPS account. Your email address will not be published. Tony EE rocketscientist We offer an industry leading 12 months warranty.

We dispatch same day if an is order placed before 4pm UK time on a working day, otherwise it will be the next working day. We offer a no argument return policy for the first month, after that give us a call and we will be sure to work something out for you. What are the alternatives to Keil software where I can simulate codes for ? With ns, this would mean a maximum communication frequency of about kHz. Choosing IC with EN signal 2. However, you might still want to consider the alternatives below, just to be sure.

Flexible logic levels When interfacing a 3. To see how it works in reality, I made a voltage divider from two 10k resistors, and measured both the voltage on MCU pin itself the xatasheet trace and from between the two resistors the red tracewhen the MCU pin is set to alternate between low and high state times a second a kHz square wave: To see how it works in reality, I made a voltage divider from two 10k resistors, and measured both the voltage on MCU pin itself the blue trace and from between the two resistors the red tracewhen the MCU pin is set to alternate between low and high state times a second a kHz square wave:.
