16-bit bus transceiver with direction pin; 3-state
7. Functional description
7.1 Function table
[1] H = HIGH voltage level
L = LOW voltage level
X = don’t care
Z = high-impedance OFF-state.
8. Limiting values
[1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] Above 55 °C the value of P
tot
derates linearly with 11.3 mW/K.
[3] Above 55 °C the value of P
tot
derates linearly with 8 mW/K.
