74HC(T)160:可预置同步BCD十进制计数器;异步复位

74HC/HCT160是高速硅栅CMOS器件,与低功耗肖特基TTL (LSTTL)针脚兼容。该类器件的规格符合JEDEC标准no. 7A。

74HC/HCT160是同步可预设十进制计数器,具有内部前视进位且可用于高速计数。

通过在时钟(CP)的正边沿上同步所有触发器时钟提供同步操作。

计数器的输出(Q0至Q3)可预设为高电平或低电平。并行使能输入(PE)处的低电平可禁用计数操作并使数据输入(D0至D3)上的数据加载到时钟正边沿上的计数器中(只要符合PE的设置和保持时间要求)。无论计数使能输入(CEP和CET)上的电平如何都会发生预设。

主复位输入(MR)处的低电平会将所有四个触发器(Q0至Q3)输出设置为低电平,而无论CP、PE、CET和CEP输入上的电平如何(从而提供了异步清零功能)。

前视进位可简化计数器的串行级联。两个计数使能输入(CEP和CET)必须为高电平才能进行计数。CET输入经前馈后可使能终端计数输出(TC)。因此而被使能的TC输出会产生一个高电平输出脉冲,其持续时间约等于Q0的高电平输出。该脉冲可用于使能下一个级联级。

级联计数器的最大时钟频率由CP至TC的传播延迟和CEP至CP的设置时间确定,计算公式如下:

fmax= (1) / (tP (max)(CP至TC) + tSU(CEP至CP) )
