概览

MM74HC164 使用先进的硅门极 CMOS 工艺。它具有标准 CMOS 集成电路的高抗扰性和低功耗。它还提供可与低功耗肖特基器件媲美的速度。此 8 位移位寄存器具有门极串行输入和 CLEAR。每个寄存器位都是一个 D 型主/从触发器。输入 A 和 B 可对传入数据进行完全控制。任一或两个输入的低电平均禁止新数据的进入，并在下一个时钟脉冲时将第一个触发器重置为低电平。一个输入上的高电平会启用另一个输入，然后确定第一个触发器的状态。当时钟为高电平或低电平时串行输入处的数据可能会更改，但只输入符合设置和保持时间要求的信息。在时钟脉冲正向转换期间，数据串行移位进出 8 位寄存器。“清除”与时钟无关，通过“清除”输入处的低电平完成。74HC 逻辑系列与标准 74LS 逻辑系列在功能和引脚输出方面兼容。通过将内部二极管箝位到 VCC 和接地，防止所有输入因静电放电受损。
