74LVT14集成電路（IC）的門反相器規(guī)格書PDF中文資料

1. General description

The 74LVT14 is a hex inverter with Schmitt-trigger inputs. 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.
