  • 1.8V JTAG Buffers / Drivers

    Resolved
    Other Parts Discussed in Thread: SN74LVC125A , SN74AUC34 , SN74AUC244 , SN74AUC125 Dear TI, Could you please recommend buffer/driver solution for 1.8V JTAG bus? Thanks

  • RE: LSF0108: pull up resistor

    Section 9.2.3 tells you that pull-up resistors on the A side are needed. For unidirectional downconversion, a buffer with overvoltage-tolerant inputs like the SN74AUC244/SN74AUC1G126 would be simpler and more robust.

  • RE: SN74HC595: SN74HC595 Current Consumption

    1. At 2 V, the worst-case resistance is 0.1 V / 20 µA = 5 kΩ. 2. The load is a constant current sink of 20 µA. Then V OH is measured. 3. Because the load is larger than 20 µA. (For currents larger than the specified I OH , the resistance…

  • RE: Looking for Buffer/driver

    the SN74AUC244 . has only 9 mA drive capability

  • RE: SN74LV541A: Can SN74LV541A support 3m SPI with good output propagation delay mismatching.

    LV-A would require at least 2 V. Try the SN74AUC244 or SN74AUCH244. But to minimize skew, you should ensure that all signal lines have the same capacitance.

  • SN74AVC8T245: Short propagation delay time

    TI Thinks Resolved
    Part Number: SN74AVC8T245 Other Parts Discussed in Thread: SN74AXC8T245 , SN74AUC244 Hi All, Please tell me the product with short propagation delay time. The SN74AVC8T245 has a propagation delay of 1-5nsec. Is there a product with a propagation delay of…

  • RE: SN74LVC16T245: Data rate questions - FPGA 2.5V to 1.8V translation

    Unused inputs can be connected directly to GND (or V CC ). You would need a pull-down/-up only if you wanted to change the input voltage during debugging. If you're using only eight channels, consider the smaller SN74AUC244. If you do not have pull…

  • SN74LVC244A: Did we have the bi-direction buffer solution for SD card application?

    TI Thinks Resolved
    Part Number: SN74LVC244A Other Parts Discussed in Thread: SN74AUC244 , Hi Sir, Did we have any bi-direction buffer/line-driver solution for SD card application which the function same as the SN74LVC244A or SN74AUC244? Thanks, George
