  • 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...

    Saravana Prabhu Sarva Kannan
    Hi Do we require PULL UP resistor, when we are using TXS0108 for level translator operation? since it has mentioned that "VOLTAGE-LEVEL TRANSLATOR FOR OPEN-DRAIN AND PUSH-PULL APPLICATIONS". Warm Regards Saravana Prabhu

    Hey, I'm trying to interface a OMAP 3530 over serial with a Delfino TMS320F28335. The OMAP3530 is in the form of a Gumstix COM with the summit break outboard, and I am using the Spectrum Digital ezDSPf28335 kit. The OMAP processor operates on 1.8V and the Delfino operates on 3.3V logic. I was attempting...

    TXS0108 has integrated pull-up resistors to save board space and cost in open-drain applications. Please refer "Pullup or Pulldown Resistors on I/O Lines" section (page 13 of 23 in datasheet) for more information. This is the response which i have received from the support...

    Craig Neely
    Hi, I'm curious about the dynamic output control (DOC) circuit discussed in the AVC technology guide SCEA006A . My question is: do all members of the AVC family have this function? Only a few devices in the family have data sheets that mention it. For instance -- I'm trying to select a...

  • Forum Post: SN74LVC1G125 as a level shifter

    Roger Plante
    I would like to use the SN74LVC1G125 as a level shifter with 3.3V supply and 5V inputs. Preliminary testing shows that this does seem to work without problems. Will input clamps turn on and cause latent failures? There is no indication in the spec that tells me if this is possible. Thanks, Roger

    I learned that there are no problems using the LVC1G125 in this application. The LVC1G125 is designed to tolerate 5.5V at its input regardless of the Vcc voltage.

    We're looking to replace an obsolete part in a TTL system with an FPGA. This will require interfacing the FPGA's 3.3V bus with the bidirectional TTL data bus. We're considering using the TXS0108, but have a few questions: 1. We've observed that the TX B 010x is unable to drive the...

    Dan McKenna
    I realize that this has been answered and has been dormant for some time, but I wanted to make a more definative answer: The TXS0108 Does NOT need external pullup resistors. The TXS0108 is intended for high drain devices and external pullups will cause problems. Integrating the pullups into...

  • 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.

    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...
