1. General description

The 74LVT125; 74LVTH125 is a quad buffer/line driver with 3-state outputs controlled by the output

enable inputs (nOE). A HIGH on nOE causes the outputs to assume a high impedance OFF-state.

Bus hold data inputs eliminate the need for external pull-up resistors to define unused inputs. This

device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables

the output, preventing the potentially damaging backflow current through the device when it is

powered down.
