MC74AC161/74 ACT 161 和 MC74AC163/74 ACT 163 是高速同步模块 -16 二进制计数器。它们是同步的，可用于可编程分隔器，具有两种类型的计数启用输入和 Terminal Count 输出，可用于多种形式的同步多工位计数器。MC74AC161/74 ACT 161 具有异步 Master Reset 输入，该输入会覆盖所有其它输入并强制输出电压低。 MC74AC163/74 ACT163 具有同步重置输入，可覆盖计数和并行加载，并允许在时钟上升沿同时重置输出。
同步计数和加载
高速同步扩展
典型计数速率为 125 MHz
输出源 / 接收器 24mA
ACT 161 和 ACT 163 具有 TTL 兼容输入
这些器件以无铅封装提供。此处的规格适用于标准和无铅器件。
