MC74HC161ADR2集成电路（IC）的计数器除法器规格书PDF中文资料

MC74HC161ADR2属于集成电路（IC）的计数器除法器。由安森美半导体公司制造生产的MC74HC161ADR2计数器，除法器计数器和除法器 IC 是数字逻辑器件，可对输入发生的逻辑转换进行计数，然后使用多个并行输出重新发送累加的计数，和/或生成单个输出信号转换，从而对应用某些整数数量输入信号转换进行响应。除了简单的事件计数，它们还可用于各种频率合成应用。

The MC74HC161A and HC163A are identical in pinout to the LS161 and LS163. The device inputs are compatible with standard CMOS outputs; with pull–up resistors, they are compatible with LSTTL outputs. The HC161A and HC163A are programmable 4–bit binary counters with asynchronous and synchronous reset, respectively.
