SN74LVC1G125: pull up/down resistor for SN74LVC1G125 & SN74LVC1G126

Part Number: SN74LVC1G125

1.  Does the output of PIN4 need a pull up resistor?

2. Is there any internal pull up or pull down resistor for PIN2?

  • The output needs a pull-up resistor only if you want to have a defined high-level voltage while the output is in the high-impedance state.

    As shown in footnote (1) of the recommended operating conditions table, the inputs do not have pull-ups or pull-downs and must not be left open.
