74HC(T)163: 可预设同步4位二进制计数器;同步复位

74HC163;74HCT163是同步可预设二进制计数器,带有内部先行进位功能。在时钟正沿(CP)上同时对所有触发器计时,即可以实现同步操作。计数器的输出(Q0至Q3)可以预设为高电平或低电平。并行使能输入(PE)为低电平会禁用计数操作。这会导致数据输入(D0至D3)处的数据在时钟的正沿上被载入到计数器中。此时,无论计数使能输入(CEP和CET)的电平是什么,均会发生预设操作。主复位输入(MR)为低电平会在时钟输入(CP)进行下一个正沿跃迁后将Q0至Q3设为低电平。无论输入引脚PE、CET和CEP的电平是什么,均会发生此操作。该同步复位特性使得设计人员能够只通过一个外部与非门修改最大计数。先行进位简化了计数器的串行级联CEP和CET必须为高电平才可以进行计数。CET输入会被前馈以使能终端计数输出(TC)。因此,使能的TC输出会产生高电平输出脉冲,其持续时间约等于Q0的高电平输出时间。此脉冲可用于使能下一个级联级。输入端包括钳位二极管。支持使用限流电阻将输入连接至超过VCC的电压。

CP至TC的传播延迟以及CEP至CP的设定时间决定级联计数器的最大时钟频率,公式如下:

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