74ALVT162821: 2.5 V / 3.3 V 20位总线接口D型触发器,正沿触发器,带 30 Ohm终端电阻(三态)

74ALVT162821高性能BiCMOS器件结合了低静态和动态功耗以及高速和高输出驱动能力。它设计用于I/O 兼容性高达5 V、在2.5 V或3.3 V电压下进行VCC操作。

74ALVT162821具有两个10位边沿触发寄存器,每个寄存器都耦合到一个三态输出缓冲器。每个寄存器的两个部分由时钟(nCP)和输出使能(nOE)控制逻辑门独立控制。

每个寄存器为完全边沿触发。在时钟从低到高转换前的某个建立时间,每个D输入的状态会被传输到相应的触发器Q输出。

三态输出缓冲器设计用于驱动重负载三态总线、MOS存储器或MOS微处理器。有源低电平输出使能(nOE)可控制所有十个不受寄存器操作影响的三态缓冲器。nOE为低电平时,寄存器内的数据会出现在输出处。nOE为高电平时,输出处于高阻抗“关断”状态,这表示这些输出既不能驱动也不能加载总线。

74ALVT162821设计在高电平或低电平输出级内使用30 Ω串联电阻。该设计可降低存储器地址驱动器、时钟驱动器以及总线接收器/发送器等应用中的线路噪声。该系列端接电阻可降低过冲和欠冲,非常适用于驱动存储器阵列。
