SN74ALVC164245: Input Current Requirements for Control Pins and I/O Pins

Sahil Bhat

Part Number: SN74ALVC164245

Hi, I am using SN74ALVC164245 IC in my design. My question is what is the current requirements at control pins(OE Pin 48 and EN Pin 1) and the I/O pins as well. As per the datasheet (Section 6.6 Electrical Characteristics), there is delta Icc and Ii current listed, but I am little confused which spec to look at when trying to understand the current requirements at control and I/O pins. Please advise. FYI, My VccA ia 3.3V and VccB is 5V.

Only I_I matters; see Understanding and Interpreting Standard-Logic Data Sheets.

Thanks. The document that you mentioned has Ii mentioned for control Inputs and A B I/O ports, so that's great. But when I look at the datasheet of the IC, it only mentions Ii for control Inputs, but not nothing about I/O ports. What should be the current at I/O ports?
