The capacitance bss138 datasheet the biggest impact in down-shifting on both rising and falling edges. My crystal ball is a bit cloudy this afternoon. Sign up or bss138 datasheet in Sign up using Google. Questions Tags Users Badges Unanswered.
BSS Datasheet(PDF) – Fairchild Semiconductor
The channel resistance essentially acts as a potential divider with Vss138 or R3 when the output is pulled low. For simplicity of the explanation, I’ll assume that LV is 3. I am asking this because I don’t have yet AOA to test. I’ve added a bit on bss138 datasheet the circuit works. It was also for a device datasjeet bss138 datasheet very sensitive to rounding of the signal edges it was an SPI flash device.
It is using BSS datasheet which I don’t have. As expected, the AOA performs badly oat this frequency. In fact, Bss138 datasheet don’t know exactly how this circuit works!
Junaid I’ve gotten 4MHz out of this type of level shifter before by using bss138 datasheet. A larger on-resistance will slow bss1338 the falling edge slightly, but given the rising edge is entirely driven by the pull-up resistor anyway, bss138 datasheet level shifter is no good for high-speed circuits any-way a few MHz tops depending on trace length and capacitive load.
When the input is pulled low, the source will be at 0V, bss138 datasheet the gate will remain at 3. Spehro Pefhany k 4 If you don’t care at all about speed it will work.
Sign up using Email and Password. Sign up using Bss138 datasheet. I’ll add a bit about how the circuit works for completeness. If you reduce the pullup resistor bss138 datasheet can gain some of the speed back but whatever is driving it will bss138 datasheet to sink more current and have an appropriately low output voltage to yield enough noise immunity and the power consumption will be higher. bss38
As such it bss138 datasheet be pulled up to 3. As such the output datashdet cannot exceed 3. However, as SpehroPefhany points out, this is not the full story. You can simulate it or build it and test it. TL;DR; It will work, but it will be slow. Post bss138 datasheet a guest Name. Do a simulation and see if it will exceed your exact requirements by a sufficient margin.
You may be able to get 1MHz from the transistor you want to use if you don’t mind very rounded edges. Bss138 datasheet the input is pulled low, the body diode of the MOSFET which goes from source to drain will start conducting and pull bss138 datasheet output down.
Speed is already pretty terrible because of the 10K pullup and other capacitance.
