SN74AUP2G07: can i pull-up the OD output of SN74AUP2G07 through Kohm to other voltage level > VCC of this part ?

hi,

i am using SN74AUP2G07 with 1.5V VCC and directly connect the OD output to input pin of other 3V device. the OD output was pull up to 3V through 10K.

since i just see in datasheet chap 6.3 ( RecommendedOperatingConditions) the Vo 's range is 0-VCC, i wonder if my design is OK or what you recommend in my application ?

thanks

The SN74AUP1G07 and SN74AUP3G07 datasheets allow 3.6 V, as expected for an open-drain output.

Apparently, the entry in the SN74AUP2G07 datasheet is just wrong. Your design is OK.

Thank you Clemens.

Polo,

As Clemens mentioned, AUP2G07 can be used for level translation using PU resistors. I will also make a note to get this corrected in the ds.

You could also consider using the SN74AXC2T45 as a 2 channel level translator for 1.5 to 3.3V level translation. There is no external pullup resistors required on this device.
