16-bit buffer/line driver; 5 V input/output tolerant; 3-state
[1]
All typical values are measured at VCC = 3.3 V and Tamb =25 C.
[2]
The bus hold circuit is switched off when VI >VCC allowing 5.5 V on the input terminal.
[3]
Valid for data inputs only. Control inputs do not have a bus hold circuit.
[4]
The specified sustaining current at the data input holds the input below the specified VI level.
[5]
The specified overdrive current at the data input forces the data input to the opposite logic input state.
