Hi team,

My customer is using the SN74CBTLV3245A now. As the datasheet we need to pull up/low the unused pins. Currently we set the A7pin float(unused), B7 pin to GND, whether it has risks? Thanks.

The A7/B7 pins are not control inputs, and can be left open. Connecting them to GND does not hurt, and has no risks.

HI Frank,

Since B7 is connected to GND, it will also bring A7 to GND potential when the device is enabled and all switches are ON. This will work during normal operation.

Thank you,

Regards,

Sandesh
