    do we have level shifterdedicated for NAND FLASH (to use with NAND FLASH 3V, AND CPU 1.8V),or need std level shifter like SN74LVC8T245?

    Andreas Schr��ck
    Hi, i tried to use the TXB0304 for our new design... During the simulation everything seems to be ok but on the real hardware nothing happens. No output signal - on any pin or in any direction. Supplies checked, OE pin checked, ... We tried every possible combination of voltages and directions...

  • Forum Post: TXB0108 TYPICAL PERFORMANCE CHARACTERISTICS

    Lucia Stewart
    Hi, I am considering using the TXB0108 voltage level translator in my design and wanted to know what the typical values for I CCA and I CCB are at different data rates. Particularly at 1Mbps. Thanks Lucia

    Anool Mahidharia
    Hi, Junjie, Thanks for that clarification. I was confused because the suggestion I got on the Raspberry-Pi forum was to go for the TXB series device. I'll post back here after we actually test it out.

    Burkhard Kaas
    Good Day All, we investigate use of the CD40109B for level-shifting between 15V CMOS and 3.3V LVCMOS (low->high and high->low). A few questions: The datasheet only specifies DC characteristics for 5V. Are there electrical characteristics available for 3.3V supply (V-CC / V-DD)? What is...

    Hi, I was looking to use this part but it now turns I need isolation also. I am pretty sure this part will not do this. I know it has the two voltage domains but it looks like it's a single/common ground plane in the device? If I need to do level translation + isolation in an EP package are there...

    Jens Olsson
    Hi, I have a Vinculum 2 (VNC2 microprocessor with USB connectivity) ( Datasheet ) It is running on 3.3 volt and I have configured an UART using RXD TXD RTS CTS I also have a proprietary modem using a UART with 2.775 volt levels. I need to connect these and was hoping to use the TXB0104 for the task...

    Hi, In the datasheet there is a power up consideration section see below in bold - My customer had the following questions - We connected the VCCB to 5V and VCCA to 3.3V. Our power sequence has the 5V coming up before the 3.3V. Does item#2 “Power up the control side of the device (VCCA for...

    Chris Andrew
    Hi I am using a SN74LVC4245A for level shifting from 5V to 3V3 to drive a LCD. I am only using four of the 8 channels for data lines, I am not clear how to tie the remaining channels to avoid oscillation etc. The datasheet says: All unused inputs of the device must be held at the associated VCC or...

    Wen73818
    HI, I am using TSX0108 translate from 2.5V (A port) to 1.8V (B port). Since I need it power up at low level on B port, I have a 10K ohm resistor pull down on B-port. When I drive A port to high, sometimes works fine, sometimes oscillating. If I change the pull-down resistor to a smaller value, say...
