As such the output voltage cannot exceed 3. Sign up using Email bss138 datasheet Password. When the input pin is high, there is nothing in datashwet circuit pulling the output down. This site uses cookies to deliver bss138 datasheet services and to show you relevant ads and job listings. TL;DR; It will work, but it will be slow. Up to what speed it will be safe to use?

When the input is pulled low, the source will be at 0V, but the gate will remain at 3. I am asking this because I datashewt have yet AOA to bss138 datasheet. If you don’t care at all dataxheet speed it will work. I’ll add a bss138 datasheet about how the circuit works for completeness.

I am thinking to build same circuit with AOA datasheetwhich I already ordered last week for a pack ofso I bss138 datasheet to receive it by next few days. If you reduce the pullup resistor you can gain some of the speed back but whatever is driving it will have to sink more current and have an appropriately low output voltage to yield enough noise immunity and the power consumption will be higher.

The list numbers bss138 datasheet to the number on the diagram at the bottom of the answer. My crystal ball is a bit cloudy this afternoon. The higher the capacitance, the slower the circuit. Probably no more than kHz data rate.

Do a simulation and see if it will exceed your exact requirements by a sufficient margin. However, as SpehroPefhany points out, this is not the full story. As such it will be pulled up bss138 datasheet 3.

Bss138 datasheet you guessed it was easy to understand up-shifting. You may be able to get 1MHz from the transistor you want to use if you don’t mind very rounded edges. For simplicity of the explanation, I’ll assume that LV is 3. Post as a guest Name. The channel resistance essentially acts as a potential divider with R4 or R3 when the output is pulled low. In fact, I don’t know exactly how this circuit bss138 datasheet Sign up or log in Sign up using Google.

The input pin is sinking current from bss138 datasheet R3 and R4. The capacitance has the bss138 datasheet impact in down-shifting on both rising and falling edges. It is using BSS datasheet which I don’t have. A screenshot of the results is shown below in case the URL breaks.

Junaid I’ve gotten 4MHz out of this type of level shifter before by using 2. As expected, the AOA performs bss138 datasheet oat this frequency.

A larger on-resistance will slow down the falling edge slightly, but given datqsheet rising edge is entirely driven by the pull-up resistor anyway, the level bss138 datasheet is no good for high-speed circuits any-way a few MHz tops depending on trace length and capacitive load. I’ve added a bit on how the circuit works. Once the MOSFET turns on, the output voltage will then drop towards zero as the current through R3 flows through the channel bss138 datasheet than the body diode.

These capacitors will also act to slow the circuit down. Speed is already pretty terrible because of the 10K pullup bss138 datasheet other capacitance. I found easy to build level shifter circuit bss138 datasheet SparkFun website. Spehro Pefhany k 4 bsss138 How it works I’ll add a bit about how the circuit works for completeness.

Sign up using Facebook. Questions Bss138 datasheet Users Badges Unanswered. It was also for a device that was very sensitive to rounding of the signal edges it was an SPI flash device. Thanks for detailed explanation!

Down-shifting with input high is also not bss138 datasheet to understand. When the input is pulled low, the body diode of the MOSFET which goes from source to drain will start conducting and pull the output down.
