NC7SZ57集成电路（IC）的门反相器-多功能可配置规格书PDF中文资料

NC7SZ57属于集成电路（IC）的门反相器-多功能可配置。由安森美半导体制造生产的NC7SZ57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。

描述 Description

The NC7SZ57 and NC7SZ58 are universal configurable two−input

logic gates. Each device is capable of being configured for 1 of 5

unique two−input logic functions. Any possible two−input

combinatorial logic function can be implemented, as shown in the

Function Selection Table. Device functionality is selected by how the

device is wired at the board level. Figures 4 through 13 illustrate how

to connect the NC7SZ57 and NC7SZ58, respectively, for the desired

logic function. All inputs have been implemented with hysteresis.

The device is fabricated with advanced CMOS technology to

achieve ultra high speed with high output drive while maintaining low

static power dissipation over a broad VCC operating range. The device

is specified to operate over the 1.65 V to 5.5 V VCC operating range.

The input and output are high impedance when VCC is 0 V. Inputs

tolerate voltages up to 5.5 V independent of VCC operating range.
