74LVC16245A; 74LVCH16245A
16-bit bus transceiver with direction pin; 5 V tolerant; 3-state
[1]
All typical values are measured at VCC = 3.3 V (unless stated otherwise) and Tamb =25 C.
[2]
The bus hold circuit is switched off when VI >VCC allowing 5.5 V on the input terminal.
[3]
For I/O ports the parameter IOZ includes the input leakage current.
[4]
Valid for data inputs of bus hold parts only (74LVCH16245A). Note that control inputs do not have a bus hold circuit.
[5]
The specified sustaining current at the data input holds the input below the specified VI level.
[6]
The specified overdrive current at the data input forces the data input to the opposite input state.
