Hello team,

Could SN74LVC1G125 can output 5V with pull-up when Vcc is 2.5V ?

Thank you and best regards,

Michiaki

The recommended operating conditions do not allow this.

Why not use an open-drain buffer like the SN74LVC1G07?

Could SN75LVC1G125 output 5V with pull-up resister at Vcc of 2.5V in Hi-Z state ?

If I_off is implemented as shown here, then it will work:
