Octal bus transceiver; 3-state
[1] All typical values are measured at V
CC
= 3.3 V (unless stated otherwise) and T
amb
=25C.
[2] The bus hold circuit is switched off when V

CC
allowing 5.5 V on the input terminal.
[3] For I/O ports the parameter I
OZ
includes the input leakage current.
[4] Valid for data inputs of bus hold parts only (74LVCH245A). 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 V
I
level.
[6] The specified overdrive current at the data input forces the data input to the opposite input state.
