SN74LVC1G57DSFR集成电路（IC）的门反相器-多功能可配置规格书PDF中文资料

SN74LVC1G57DSFR属于集成电路（IC）的门反相器-多功能可配置。由德州仪器制造生产的SN74LVC1G57DSFR门和反相器 - 多功能，可配置可配置逻辑栅极系列产品能以与标准逻辑栅极类似的方式，对单个逻辑信号执行基本逻辑运算，但并非局限于一个特定功能（例如 AND、NAND 等）。它们通常在内部使用少量逻辑门来实现，经过选择和互连后，以便通过选择操作数据所应用的输入以及任何未使用的输入在驱动后的逻辑状态，来配置所实现的整体逻辑功能。

3 Description

The SN74LVC1G57 device features configurable

multiple functions. The output state is determined by

eight patterns of 3-bit input. The user can choose the

logic functions AND, OR, NAND, NOR, XNOR,

inverter, and buffer. All inputs can be connected to

VCC or GND.

This device functions as an independent gate, but

because of Schmitt action, it may have different input

threshold levels for positive-going (VT+) and negativegoing

(VT–) signals.

This configurable multiple-function gate is designed

for 1.65-V to 5.5-V VCC operation.

This device is fully specified for partial-power-down

applications using Ioff. The Ioff circuitry disables the

outputs, preventing damaging current backflow

through the device when it is powered down.

NanoFree™ package technology is a major

breakthrough in IC packaging concepts, using the die

as the package.
