SN74LVC1T45-EP: Input Impedance

Michael T Schneider

Part Number: SN74LVC1T45-EP

Team, can we confirm the below?

I am trying to verify that the normal operating input impedance for the ‘A’ input on the SN74LVC1T45-EP IC is above 100k ohm. Any help with resolving this would be much appreciated.

Michael,
The input impedance can be estimated from the leakage parameters in the DS.
For worst case, A port has +/-6uA of leakage with 5.5V to GND. This results in a min impedance of 916.6Kohm.
