  • Forum Post: Using SN74LVC32244

    Jeffrey Bledsoe
    I have a design where the enable pin of this part is connected to ground (always enabled) and Vcc = 3.3V. The output is pulled up with a 5.6k resistor to 5V. I see 3.3V on the output pin, even with the pullup. Possible explanations: The 3.3 V power supply is sinking current through a body diode...

    Robert Lewis
    I thought this was a simple circuit but I am not getting correct logic. We have four gates connected to produce a single output if any one of 5 inputs goes low. This is powered at 3.3V. 1,2 are inputs from switch ( 1 & 2) --> 3 4,5 are inputs from switch ( 4 & 5) --> 6 (6 connects...

    Robert Lewis
    We need to interface between a 3.3v logic signal driven by a regulated 3.3v supply which is mated to a 3. 3v - 2.0v battery system. As the battery discharges over time we need to be maintain the logical signal connection. There are 2 signals and they are uni-directional. We have tried a mosfet but can't...

  • Forum Post: SN74LV8151 Input Voltage Tolerance

    Robert DeMott
    Could someone confirm whether the SN74LV8151 inputs are 5V tolerant when operating from a 3.3V supply? The recommended operating conditions section of the datasheet seems to imply that they are (max input voltage of 5.5V), but this isn't explicitly stated in the part description. Thanks.

  • Forum Post: Schmitt trigger output gone bad?

    Gary
    Hello, I am using a 74LVC14A inverting buffer for Vishay opto sensors, to convert 5V signal to 3.3V and feed into LPC2132 pins. The output of optosensors is fine, a good square wave but the output of schmitt trigger is distorted. Please see the scope output: The yellow trace is optosensor output...

    Dear Sir, I am using CLVCH16T245MDGGREP level translator in my project for 3.3 to 2.5V and vice versa. I want to know that what is the maximum input frequency i can operate, because data sheet it is not given. I have one more doubt. I am using virtex6 LXT in my project.i want to drive a...

  • Forum Post: Using a CBT Device as a 5V-to-3.3V Level Shifter or Voltage Translator

    Mike Combs
    The CBT logic family can interface a 5V part of a system with a 3.3V part of a system by adding a diode between the external Vcc and the output-enable terminals. Please reference application report "Flexible Voltage-Level Translation with CBT Family Devices": http://www.ti.com/lit/scda006...

    Intruppt Handlers how to add in start up file. Example timer1handler it is in source file and its prototype is in header file. I am try to add a header file in start file it showing errors. if i gave exturn also it showing error. Please let me know if any other method to solve this.

  • Forum Post: Can you operate Shift Register SN74HC595 on mixed voltages ?

    Brian Clark
    Hi- can you apply 5V to the Vcc but use 3.3V on the logic inputs on the above IC ? Secondly, the datasheet doesn't specifically describe performance with 3.3V on Vcc but can someone guide whether there would be any issues running the chip on 3.3V?
