TXS0104V: Pull up within device on VccB side

Mike

Part Number: TXS0104V
Other Parts Discussed in Thread: TXU0304

Tool/software:

Hi,

The device to interface with (TI TUSS44x0) has on the VccB side: internal pulldown on SCLK, SDI pins and pullup on NCS. Will that interfere with the TXS (e.g. One Shot Accelerator)?

Thanks,

The TXS has internal pull-up resistors and open-drain outputs; it must not be used with pull-down resistors.

For fixed-direction signals, the best solution is a fixed-direction translator like the TXU0304.

Good recommendation. Didn't notice that in the part search for fixed-direction the "Configuration" column selected quantity of AtoB, BtoA ports within the device.

Thanks again.
