Renesas 的快速 CMOS 技术 (FCT) 逻辑系列专为用于标准 TTL 逻辑应用而设计。 我们的快速 CMOS 器件具有目前市面上最高的逻辑速度和业内最低的功耗。 快速 CMOS 系列由各种产品组成,其中包括总线接口、缓冲器、多路复用器、收发器和其他器件。 我们提供两种可用输出配置,即行业标准高驱动和低噪声平衡驱动。 所有器件均具有多个速度等级。
基本的 CMOS 锁存器电路拥有两个输入(SET 和 RESET)和一个输出。 器件可提供高电平或低电平两种形式,并决定了将由逻辑高电平还是逻辑低电平信号来触发 CMOS 锁存器。CMOS 锁存器的目的是监控 SET 输入,并且一旦触发就会改变并保持输出状态,直至其被 RESET 输入重置。 换句话说,CMOS 锁存器在检测到 SET 引脚的状态发生变化时(哪怕只是一小会)锁定为“开”,并将一直保持“开”状态直至检测到 RESET 引脚的状态发生变化。
CMOS 锁存器被设计为透明锁存器的原因在于,它们可在从低转至高(或高转至低,取决于架构)时允许输出参照输入。 因此,当几个透明锁存器彼此参照(使用相同的输入信号)时,这些信号可以通过所有锁存器同时传播。 Renesas 的低功耗快速 CMOS 锁存器是临时数据存储的理想之选。 它们可用于实施存储器地址锁存器、I/O 端口和总线驱动器。
请注意,CMOS 锁存器类似于触发器,但“锁存器”一词主要用于存储元件,而时钟器件则被称为“触发器”。” 此外,锁存器通常由电压电平触发,而触发器则通常由电压变化(或边缘)触发。 也就是说,锁存器在启用时变成透明,而触发器的输出则仅在单一类型(正向或负向)的时钟脉冲边沿发生变化。
八进制缓冲器是包含八个相同缓冲器的标准逻辑器件。 高阻抗输入可显著减少输入驱动程序的电流负载,而八进制缓冲器输出则提供了更出色的驱动力和交换噪声性能。 Renesas 的八进制缓冲器(线路驱动器)采用先进的双金属快速 CMOS 技术打造而成,可用作存储器、地址驱动器、时钟驱动器或总线用发射器/接收器以增加电路板密度。
