说明

Onsemi(前身为 Fairchild)的 NC7SZ11P6X 是超高速 (UHS) TinyLogic 系列的单通道 3 输入 AND 门,采用 6 引脚 SC-70-6 (SOT-363) 封装(2.0 x 1.25 mm)。其工作电压为 1.65 V 至 5.5 V,最大静态电流为 2µA。主要规格包括:5 V 下传播延迟 2.7-ns(典型值),5 V 下最大 7.5-ns(50-pF 负载),5 V 下 ±32-mA 输出驱动,过压耐受输入高达 7 V,与 VCC 无关。当 VCC 为 0 V 时,输出为高阻抗。具有已获专利的降噪/EMI 电路。工作温度范围为 -40°C 至 +85°C。.

NC7SZ11P6X 是安森美 TinyLogic UHS(超高速)系列中的单通道 3 输入 AND 门,该器件最初由飞兆半导体公司设计,后被安森美收购。该器件采用先进的 CMOS 技术制造,可在 1.65 V 至 5.5 V 工作范围内实现高速、高输出驱动,同时保持低静态功耗。.

3 输入 AND 函数计算 Y = A AND B AND C。这对于多条件使能电路、地址解码和故障检测非常有用,因为在这些电路中,必须同时满足三个独立的条件才能采取行动。.

NC7SZ11 在 5 V 电压下的典型传播延迟为 2.7-ns(50-pF 负载时最大为 7.5-ns),因此适合高速数字逻辑。5 V 时的±32-mA 输出驱动可直接驱动 LED、继电器线圈和多个 TTL/CMOS 输入,而无需缓冲器。.

输入端可承受高达 7 V 的电压,与 VCC 无关,因此即使在 1.8 V VCC 下工作,器件也能接受 5 V 信号。这对于电压转换非常重要--即使栅极采用 1.8 V 供电,5 V 输入信号也能被正确识别为逻辑高电平,而且 1.8 V 输出与下游 1.8 V 逻辑兼容。.

当 VCC 为 0 V 时,输入和输出为高阻抗,可防止部分供电系统中出现回流电流。2µA 的最大静态电流使该器件适用于始终保持接通的逻辑。.

SC-70-6 (SOT-363) 封装仅占电路板面积 2.5 平方毫米,是目前最小的逻辑门封装之一。因此,NC7SZ11 非常适合在空间有限的设计中添加胶合逻辑,因为在这种设计中,完整的 PLD 或 CPLD 显得过于多余。.

后缀 P6X 表示 SC-70-6 卷带封装。其他封装选项包括 P5X(SOT-23-5)和 M5X(MicroPak-5)。.

**CMOS AND 逻辑门:** NC7SZ11 使用互补 CMOS 晶体管实现布尔 AND 功能(Y = A - B - C)。输入级由三个串联的 NMOS 晶体管和三个并联的 PMOS 晶体管组成。当所有三个输入都为高电平时,所有三个 NMOS 晶体管都导通(通过串联链建立一条从输出到地的通路),而所有三个 PMOS 晶体管都关断。当任何输入为低电平时,相应的 NMOS 晶体管关闭(断开串联链),相应的 PMOS 晶体管导通(建立从 VCC 到输出的通路)。.

**通过将输入保护二极管与 VCC 轨隔离,并使用浮动 n-阱结构,可实现这一功能。当输入电压超过 VCC 时,VCC 的寄生二极管会反向偏置,防止电流流入 VCC。.

**断电高阻抗:** VCC = 0 V 时,内部电路会禁用输出驱动器,使输出处于高阻抗状态。这可防止器件在无电源时产生或沉没电流,这在热插拔和多电压系统中至关重要。.

**降低电磁干扰:** 获得专利的噪声/电磁干扰降低电路可稍微减慢输出边沿速率(受控回转速率),以减少导致电磁干扰的高频频谱内容,同时保持可接受的传播延迟。.
