Hi, I am working on a logic circuit will be near to a high power switching device (hundreds of Amps). I wonder level translator and logic gates in 15V logic level such as HEF4104, how much is immune to the noises and radiation. thank you.
So I can't connect it like this? 134473 I need level translator? Yes on all the lines going between the ESP8266 and the HX711. This is mentioned on the summary page for the ESP8266 device on sparkfun. Note: The ESP8266 Module is not
Sounds like you are driving FPGA SDA line not correctly as open drain. You say the I2C slave is driving SDA low but only reaches 0.7 V. What's the voltage on both sides of the level translator in this situation? What's the high level?
Hello, I'm trying to connect mcp2515 to LinkIt ONE board(compatibile with Arduino). I'm using LinkIt ONE(digital pins operates at 3.3v) + level translator(TXB0108PWR) + CAN module with MCP2515 and TJA1050 on board. I cannot fully determinate whether my initializations goes wrong or good. Each time I read register value it returns different respon
The output signal polarity (default P1.0 high level is activating the power) might re-enable the power supply during switch-off. You should change the circuit to use active low level for power on. A NPN in common base circuit can be used as non-inverting level translator.
Is there an CMOS voltage translator or level shifter that works with the input voltage outside of power supply range? My power supply is 1.2V but the input voltage ranges from -0.4V to 1.3V. I want to shift the input voltage to some level that is within the power supply range. Thank you.
Look at the required logic levels... you may need a level translator, and a separate PSU if you need to generate 3V3 for the USB board.....
Transceiver is a device that can be used for transmit and recieving of data. Thus, two components that do not have a tri-state output can be connected together and commmunicate without contention on a bus. If level translation is required since the two devices work at different power supply voltages, this must be done to prevent device damage. I
Hi I am working with TXB0106 level translator (datasheet). While doing design, I came across page 12 in which an architecture of an I/O cell is displayed as shown below. 123267 In page 14, it's stated that during output transition from high to low, and vice v
Hi all... I am working on a project which required 7"TFT screen. I found many types of tfts with parallel interface (16/8bit). and some TFT panels also. my question is > if I am using a 3.3V display , is there any level translator is necessary to interface? >>is there any available solution to plug the TFT panel directly to arduino? >>>IS
Hi All, Fairchild FDV301 has Vth(max) at 1.06V I should be able to use it to reliably convert 1.8V LVCMOS level to 3.3V. Is that correct? Thank in advance for all help.
Hello, I am looking for high-speed level shifter or level converting latch or level converting flip-flop. With high-speed operation ~ 3GHz. Please give me any suggestion. Thank you and have a nice day.
Using a logic level serial link is prone to pick up electrical noise but should basically work, at least most of the time. If it doesn't work at all, there's probably a problem in your hardware or software, not related to using logic level interface. In other words, a problem that can't be read from your posts.
1) You're going to need a level translator to go from TTL to CML 2) Your microcontroller is not going to work with 1GBPS data unless it has an internal PLL or some other way to increase its internal frequency. 3) So you don't a level translator after all.
Can the 3v3 power supply source supply enough current to the board (about 350mA bursts I think) Which version of esp8266 board do you have and what firmware does it run? Are you using a 5v to 3v3 level translator? (assuming 5v AVR) Is GPIO pin 2 pulled up? Are you able to connect to the wifi using a serial terminal commands from the PC?
I don't know about ZigBees but I have used XBee Pro. There is a configuration software which can be used to set the baudrate of XBee. XBee's work at 3.3V and hence need Voltage level translator to connect to PIC which work at 5V.
Simulation shows that input audio amplifier will work OK. Pre-emphasis cap 1.5nF will give 50us (40us now). Simulation with TL071 shows useless gain/frequency characteristics. It seems that amplifier design perfectly suits to LM741 OPA. Between 74ls390 and 4027 is level translator which enables triggering CMOS FF from 5V TTL. MPX filter has no
Any time you specify voltage, high speed and logic, one also needs to specify impedance of source, load , capacitance and current. The fanout requirements for 1 gate load are trivial compared to level translator for a clock driver with 20 loads. The slew rate of your Op Amp is probably the limiting factor in your design. CMOS is a much bet
Is it ok if I replace 5V directly to 13.6V and drive the transistor from MCU ? 0V from MCU = active. No, this doesn't work. You need a level translator, an additional NPN transistor can do the job. Either in CE configuration (inverting) or in CB configuration (non-inverting).
It would appear to be some sort of common-base level translator. 0V at the emitter input (transistor off) gives 5V at the collector output. A sufficiently negative voltage at the emitter input (transistor on) gives 0V (or a slightly negative voltage) at the collector output.
