74LVC2G38GM集成電路（IC）的門反相器規(guī)格書PDF中文資料

1. General description

The 74LVC2G38 is a dual 2-input NAND gate with open-drain outputs. Inputs can be driven from

either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed

3.3 V and 5 V environments. Schmitt-trigger action at all inputs makes the circuit tolerant of slower

input rise and fall times.

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.
