储存器和逻辑器件

Renesas 的 ALVC（高级低电压 CMOS）逻辑器件系列是专用于低压应用的高性能总线接口组件。 ALVC 系列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。Renesas 可提供具有 16 位或 32 位两种总线宽度的三态缓冲器、驱动器、锁存器和收发器。

Renesas 的 ALVC 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) ALVC 零件适合重负载。
  • 平衡驱动ALVC 零件使用内部串联电阻控制输出波形的上升沿和下降沿，并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ALVC 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。
