TLK10232 - Input pins

Other Parts Discussed in Thread: TLK10232

Hello Team,

Please allow me to ask you about the TLK10232 input pins. There are description in the datasheet for pins below that they have internal pull-up or pull-down.

Are there any other input pins which has internal pull-up or pull-down, which is not shown in the datasheet ?

Best Regards,

Kawai

    Hi Kawai,

    If the datasheet does say that they have pull down/up resistors internally, then it should be OK to leave them floating in the application. Hence, in some cases, datasheet does not mention that some pins are pulled down/up, and in fact, the RTL code of the device indicates that they have neither pull-up or pull-down resistors and are simply connected to an input buffer. If this is the case, the pins must be externally driven high or low through a Microcontroller, FPGA or Pull-up / Pull-down resistors.

    I hope this helps.

    Best Regards!
