SN74LVC2G126: Pull-up resistor on output

Michele Gurrado

Part Number: SN74LVC2G126
Other Parts Discussed in Thread: SN74AUC1G126

Hi,

is it possible to use a pull-up resistor applied to the output of this device to fix the output to high value when in hi-z mode?

Thanks

Thanks,

any suggestions for optimal pull-up value?

Simulating it in p-spice for ti the output goes low when OE is disabled, whatever is the pull-up resistor value..

Last question: is this applicable to the pn SN74AUC1G126 too?

Thankyou so much

A typical value is 10 kΩ.

The model might not be correct.

Yes.
