74LVC1G57中文资料Single-gate数据手册Diodes规格书

描述 Description

The 74LVC1G57 is a single 3-input positive configurable multiple function gate with a standard totem pole output. The output state is determined by eight patterns of 3-bit input.
The user can chose the logic functions AND, OR, NAND, NOR, XNOR, inverter or non-inverting buffer. All inputs can be connected to ground or Vcc as required. The device is designed for operation with a power supply range of 1.65V to 5.5V. The inputs are tolerant to 5.5V allowing this device to be used in a mixed voltage environment. The device is fully specified for partial power down applications using IOFF.
The IOFF circuitry disables the output preventing damaging current backflow when the device is powered down. The user is reminded that the device can simulate several types of logic gates but may respond differently due to the Schmitt action at the inputs.

简介

74LVC1G57属于集成电路（IC）的门反相器-多功能可配置。由制造生产的74LVC1G57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。
