Part Number: SN74GTL2003
Other Parts Discussed in Thread: LSF0108

Hello Team,

Let me clarify my understanding.

Can the Sx and Dx pull-up supply be used at 1V to 5V if Vsrer=1V, Vgref=Vdref=3.3V?

I want to check about the SX/Dx pull-up power supply can be used higher Vgref.

Best regards,

Sato

V_GREF/V_DREF are not directly connected to 3.3 V; the 200 kΩ resistor drops some voltage.

Anyway, you can pull up to any voltage; the only requirement is that V_SREF is the smallest voltage.

For practical purposes, this device is identical with the LSF0108; see [FAQ] How do the LSF translators work?
