    Can you help designing this buffer?

    I would like to make this circuit on stripboard. This is actually a buffer on the input in one of the Boss pedals, with some modification, so that the signal leaving the circuit is reduced with 50% in the end. On the photo below, on the left side, you can see the original buffer circuit from...

    what is the maximum delay that can be accomodated by SPI communication?

    Hi, Problem statement: I am using SPI communication from microcontroller to slave with quad channel buffer in between so the signal path is CONTROLLER<->BUFFER<->SLAVE MISO, MOSI, CLK, CS are passing to slave via buffer from controller. I am operating SPI at 8MHZ,2.4V, SPI mode 0. the...

    Pushing a button press from a driver to 3 different transistors with tree state logic

    I am working on a project within my company that involves a relay board used to control three different motors when an external 24V button is pressed. The existing setup works based on this principle. Now, I have been tasked with designing a new board that maintains the current logic while...

    What is the use of an 3-state octal buffer/line driver?

    Hello all, I have encountered an AHC244 chip used to drive LEDs (Something like in the attached image) so I wondered why not just drive the LEDs with the uC pins? And also I have seen this IC used with some PWM signals as inputs to it! in this case, I am guessing the output would be the same...

    Does anyone come across this semiconductor manufacturer?

    Hello, I am trying to identify this IC (see attached image), the part number is clear enough to know the chip but I couldn't figure out which chip manufacturer from the logo on the IC! The PN is AHCT244 which is an octal buffer/driver. One more question, why there are some parts that are...

    Oscillations on output of loaded LM675 for all positive voltages.

    Hello, I'm trying to use an LM675 power op-amp IC as an output buffer for a signal generator. For stability, I've configured this IC as a non-inverting amplifier with a gain of 11 as per the circuit diagram below. As also recommended in the datasheet, I routed separate ground returns for the...

    Inverter Buffers - Find CIn & CLoad, FanIn & FanOut

    Hi Community, I am currently studying delay propagation in inverter buffers and the properties of FanIn and FanOut. In the data-sheet we can find the two values of Cin and CLoad. I would like to know how to measure them in practice and determine the values FanIn and FanOut? Here the Datasheet...
