Part Number: SN74AUP1G07
Other Parts Discussed in Thread: SN74LVC3G07, SN74LVC2G07, SN74LVC07A, SN74LVC1G07,

Hello expert,

Could you kindly let us know the Ron value for SN74AUP1G07DCKR? We cannot find the value in datasheet or I find in the wrong way. Customer is searching for Ron<15ohm buffer. If SN74AUP1G07DCKR cannot support this requirement, please kindly help to provide a suitable device for us. Thanks a lot!

Best regards,

Ann Lien

The output impedance of a logic device can be calculated from V_OL and I_OL; see [FAQ] What is the output voltage (VOH or VOL) when the output current is X or the supply voltage is Y?

This depends on the supply voltage, which you did not specify.

You can find the strongest outputs in the LVC family, so see the SN74LVC1G07. If that is not enough, you can combine multiple outputs (SN74LVC2G07, SN74LVC3G07, or SN74LVC07A).

Hello Clemens,

Customer still have below question, could you kindly help on it?

1. Is Ron=output impedance? If no, we would like to search resistance between input and output <15ohm device.

Best regards,

Ron is a measure used for switches. The SN74AUP1G07 is a buffer, not a switch; its input is isolated from the output.

You could view the SN74AUP1G07 as a switch that connects the output to GND (not to the input). In that case, the output impedance is Ron.

What is the application?

Hello Clemens,

Thanks for reply. so it means that output and input is isolated, there is no Ron if we use this solution as a buffer. Got it and thanks for reply!
