* LVT claims, but does not specify, 5V–Tolerant outputs. LCX can be used to replace LVC; be careful when exchanging LCX with LVC as not all
LVC functions have 5V–tolerance!!
The following graph compares the 5V–tolerance capability of LCX, LVC and LVT. When LCX is not driving the bus (outputs are
disabled), the levels on that bus can exceed the LCX VCC with no adverse effect on the device or any loading on the bus. In fact,
test data shows that a disabled LCX output can “tolerate” signals over 13V on the outputs!
