Notes

When IBB transitions to >100 µA.

When IBB transitions to <100 µA.

10.

Enable pin has an internal current pull-down. Pull-down current is measured with CEN pin at 0.3 VDD.

11.

Measured by ramping TX down from 0.7 VDD and noting TX value at which ISO falls below 0.2 VBB.

12.

Measured by ramping TX up from 0.3 VDD and noting the value at which ISO rises above 0.9 VBB.

13.

Tx pin has internal current pull-up. Pull-up current is measured with TX pin at 0.7 VDD.

14.

Thermal Shutdown performance (TLIM) is guaranteed by design but not production tested.
