4.Measured by ramping Tx down from 0.7 VDD to 0.3 VDD and noting Tx value at which ISO falls below 0.2 VBB.
5. Measured by ramping Tx up from 0.3 VDD to 0.7 VDD and noting the value at which ISO rises above 0.9 VBB.
6.Tx pin has internal current pull–up equivalent to greater than 50 k
. Pull–Up current measure with Tx pin at 0.7 VDD.
7.Thermal Shutdown performance (TLIM) is guaranteed by design but not production tested.

NOTES:
1.ISO ramped from 0.8 VBB to 0.4 VBB, Monitor Rx, Value of ISO voltage at which Rx transitions to 0.3 VDD.
2.ISO ramped from 0.4 VBB to 0.8 VBB, Monitor Rx, Value of ISO voltage at which Rx transitions to 0.7 VDD.
3.Input Hysteresis, VHys(ISO) = VUTP(ISO) – VLTP(ISO).
4.ISO Pull–Up has >100 k
internal pull–up to VBB.
5.ISO has internal current limit.
6.Time required ISO voltage to transition from 0.8 VBB to 0.2 VBB.
7.Changes in the value of CISO affect the rise and fall time but have minimal effect on Propagation Delay.
8.Step Tx voltage from 0.2 VDD to 0.8 VDD; Time measured from VUTP(ISO) until VISO reaches 0.3 VBB.
9.Step Tx voltage from 0.8 VDD to 0.2 VDD; Time measured from VLTP(ISO) until VISO reaches 0.7 VBB.
