6.1 Function table
[1] A-to-B data flow is shown. B-to-A is similar, but uses OEBA, LEBA, and CP. It is not recommended to
set OEAB and OEBA LOW at the same time.
X — don’t care
H — HIGH voltage level
L — LOW voltage level
Z — high-impedance OFF-state
LOW-to-HIGH transition
[2] Output level before the indicated steady-state input conditions were established, provided that CP
was HIGH before LEAB went LOW.
[3] Output level before the indicated steady-state input conditions were established.

7. Limiting values
[1] Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any conditions beyond those indicated under Section 8 “Recommended operating conditions” is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
[2] The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150 °C.
[3] The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
Table 8: Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134). See Table note [1] and Table note [2]
