74AVC16245
16-bit transceiver with direction pin; 3.6 V tolerant; 3-state
5.2 Pin description
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 input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] Above 60 C, the value of P
tot
derates linearly with 5.5 mW/K.
