Cool, I had forgotten that. The input signal high level VIH can exceed the VDD supply voltage when these devices are used for logic level conversions. Oh, and I also have a real life, but lets not talk about it! datashee

Level Shifting 101

This way the output will sink current, something it should be better at of course, the LED will now light when output is LOW…. Please edit your post to include it there. In your case you want to switch the backlight on and off. Here’s a schematic of what I want to do with the chip: Flexible logic levels When interfacing a 3.

Considering I only knew how to use resistors as voltage dividers, I decided to learn a bit more about voltage level shifting. 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.

Close Your message datzsheet been sent. One waveform spends ns in high state and ns in low state — if this was a clock signal from 3. An identification of the calibration method eg. At ns, catasheet propagation delay limits the use of this circuit to low frequency signal switching. After calibration is performed, you will receive an ISO certificate from Intertek, which is valid for 12 months. Also, no actual resistor is ideal, so even the resistors themselves have a tiny amount of capacitance.

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: Hello, the LCD screen does not have a datasheet but here is a link to the product. Please contact our partner Intertek directly for a re-calibration of your device: The first level shifting part is the hex non-inverting buffer.

We will check the case and contact you datasehet soon as possible. High Level Output Current. Items which are on stock will be shipped out for calibration within 24 hours. A description model and identification eg. The pinout is also very simple: This time I wired the part to both 3. When interfacing a 3. Most likely the bi-directional logic level shifter does direction sensing in the pins, and also features the possibility to get signal from low voltage side to high voltage side.

This part is only one of datazheet many buffers that can do the shifting the other way around — from low to high, for example from 3. Leave a Reply Cancel reply Your email address will not be published.

The waveform looks very good with hardly any delay when compared to the original trace. Simple low to high conversion: This site uses cookies: I would like to know the performance limitations of this simple setup. The reading and accuracy of the instruments may change over time.
