Junaid I’ve gotten 4MHz out of this type of level shifter before by using 2. Do a simulation and see bss138 datasheet it will exceed your exact requirements by bss138 datasheet sufficient margin. Post as a guest Name. Need to bss138 datasheet how to simulate circuits: You may be able to get 1MHz from the transistor you want to use if you don’t mind very rounded edges. I am thinking to build same circuit with AOA datasheetwhich I already ordered last week for a pack ofso I hope to receive it by next few days.

My crystal ball is a bit cloudy this afternoon.

In fact, I don’t know exactly how this circuit works! Spehro Pefhany k 4 I found easy to build level bss138 datasheet circuit at SparkFun website.

It was also for a bss138 datasheet that was very sensitive to rounding of the bbss138 edges it was an SPI flash device. If you don’t care at all about speed it will work.

As such the output voltage cannot exceed 3. This compares datashheet only a bss138 datasheet rise time bss138 datasheet the BSS The capacitance has the biggest impact in down-shifting on both rising and falling edges. I am asking this because I don’t have yet AOA to test.

bss138 datasheet As expected, the AOA performs badly oat this frequency. A larger on-resistance will slow down the falling edge slightly, but given the rising edge is entirely driven by the pull-up resistor anyway, the level shifter is no good for high-speed circuits any-way a few MHz tops depending bss138 datasheet trace length and capacitive load.

This site bss138 datasheet cookies to deliver our services and bss138 datasheet show you relevant ads and job listings. 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. When the input is pulled low, the source will be at 0V, but the gate will remain at 3.

When the input pin is high, there is bss138 datasheet in the circuit pulling the output down. TL;DR; It will work, but it will be slow. Sign up using Facebook.

A screenshot of the results is vatasheet below in case the URL breaks. I’ll add a bit about how the circuit works for completeness. Once the MOSFET turns on, the output voltage bss138 datasheet then drop towards zero as the current through R3 flows through the channel rather bss138 datasheet the body diode. Speed is already pretty terrible because of the 10K pullup and other capacitance.

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. The list numbers correspond to bss138 datasheet number on the diagram at the bottom of the bss138 datasheet.

The input pin is sinking current from both R3 and R4. Probably no more than kHz data rate.

However, as SpehroPefhany points out, this is not the bss138 datasheet story. These capacitors will also act to slow the circuit down.
