  RE: SN54ACT244: Looking for a buffer IC accepting +3.3V inputs running off +5V

  Although i modified my question for a +10mA or -10mA current , i think the design will still work with the 8mA SN74AHCT1G125 part. Thanks David Nyarko

  SN74AHCT1G125: About the case of using at high altitude

  TI Thinks Resolved

  Part Number: SN74AHCT1G125 Hi Are there any concern about the case of using at high altitude ? Here is the conditions - Altitude : 4000 – 5000m - Atmosphere : 600 – 900 hpa Thank you and best regards, Michikai

  RE: SN74LV1T125: Do we have an alternate solution with SN74LV1T125DCKR that have thinner packge

  Depending on the voltages used, it might be possible to use SN74AHC1G125 or SN74AHCT1G125, which are available in the SOT-5X3 (DRL) package.

  RE: TXS0108E: level shift for SPI and UART

  So you need to shift ten channels up, and two channels down? Translating from 3.3 V to 5 V could be done with shifters like the SN74LVC8T245 and SN74LVC2T45, but these particular voltages can also be handled by plain buffers with TTL-compatible inputs...

  RE: SN74LVC1G11: SN74LVC1G11 application questions

  1. No; V IH is 3.5 V. To convert from 3.3 V to 5 V, add a buffer with TTL-compatible inputs (e.g., SN74AHC125, or multiple SN74AHCT1G125). 2. Yes; LVC (and AHC) inputs are overvoltage tolerant. See [FAQ] Is the reliability of a logic device affected...

  RE: TXB0104: Trying to adapt voltage levels for an SDI-12 bus with a 3.3V MCU

  None of the translators with automatic direction sensing can drive a high level. Furthermore, none of the direction-controlled translators have a Schmitt-trigger input (which is necessary due to the low slew rate). To drive the data line, use a 5 V...

  RE: SN74LVC1G17: Is this buffer adequate for CSYNC signals?

  Thank you, that's very clarifying information. So the SN74AHCT1G125 will accept both CMOS and TTL inputs powered with 5 V, behaving as a Schmitt-trigger? What I want to do is buffer CSYNC signal that may be CMOS or TTL (and probably noisy) in a...

  RE: LSF0102: Logic Low level not zero

  These voltages imply that some other device sinks current. Is there anything else connected to these signal lines? I do not know why that table mentions four-channel devices for UART. You could use the TXS0102 (which is like the LSF0102, but with edge...
