Dual-bit, dual-supply voltage level translator/transceiver; 3-state
8. Limiting values
[1] The minimum input voltage rating and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] V
CCO
is the supply voltage associated with the output port.
[3] V
CCO
+ 0.5 V should not exceed 4.6 V.
[4] For VSSOP8 package: above 110 C the value of P
tot
derates linearly with 8 mW/K.
For XSON8 packages: above 118 C the value of P
tot
derates linearly with 7.8 mW/K.
9. Recommended operating conditions
