32-bit bus transceiver with direction pin; 5 V tolerant; 3-state
6. Functional description
[1] H = HIGH voltage level; L = LOW voltage level; X = don’t care; Z = high-impedance OFF-state
7. Limiting values
[1] The minimum input voltage ratings may be exceeded if the input current ratings are observed.
[2] The output voltage ratings may be exceeded if the output current ratings are observed.
[3] All supply and ground pins connected externally to one voltage source.
[4] Above 70 C the value of P
tot
derates linearly with 1.8 mW/K.
