储存器和逻辑器件

Renesas 的低电压 CMOS (LVC) 逻辑系列由专用于低压应用的高性能总线接口组件组成。 这些器件与具有类似名称的行业标准组件完全兼容，专为 3.3V 和 2.5V 操作而设计。 低电压 CMOS 组件专为具有 5V 公差的热插入应用而设计。 这些器件的输入或输出端都没有至 VDD 的钳位二极管，从而使接口耐压能力高于 VDD。 Renesas 可提供低电压 CMOS 数据缓冲器、驱动程序、锁存器、总线收发器和触发器。

低电压 CMOS 系列共有三个基本选项可供选择：高驱动、平衡驱动和总线保持。

  • 高驱动 (±24mA) 低电压 CMOS 零件适合重负载。
  • 平衡驱动低电压 CMOS 零件使用内部串联电阻控制输出波形的上升沿和下降沿。 平衡驱动通过控制输出沿速率提供卓越的低噪声性能，可在不牺牲速度性能的情况下实现所有输出信号的局部串联端接。 在大多数应用中不需要其他线路端接。 对称驱动功能将利用类似边沿速率驱动高和低传输线，解决大部分线路平衡和端接问题。
  • 总线保持低电压 CMOS 零件可在总线被禁用或没有活动驱动器时保持总线的最后活跃状态。
