模拟多路复用器/信号分离器,带 LSTTL 兼容输入

Favorite

概览

MC74HCT4051A、MC74HCT4052A 和 MC74HCT4053A 使用硅门极 CMOS 工艺来实现快速传播延迟、低导通电阻和低关断漏电流。这些模拟多路复用器/信号分离器控制在完整电源范围(从 VCC 到 VEE)内变化的模拟电压。 HCT4051A、HCT4052A 和 HCT4053A 与金属门极 MC14051AB、MC14052AB 和 MC14053AB 的引脚输出相似。沟道选择输入通过模拟开关决定将哪个模拟输入/输出联接公共输出/输入。启用引脚为高电平时,所有模拟开关关闭。沟道选择和启用输入与标准 CMOS 和 LSTTL 输出兼容。 此类器件的设计使得基于输入电压的导通电阻 (Ron) 比金属门极 CMOS 模拟开关的 Ron 更为线性。 有关带抑制电流保护的多路复用器/信号分离器,请参见 HC4851A 和 HCT4851A。
