MC74HC163A集成電路（IC）的計數(shù)器除法器規(guī)格書PDF中文資料

MC74HC163A屬于集成電路（IC）的計數(shù)器除法器。由安森美半導(dǎo)體公司制造生產(chǎn)的MC74HC163A計數(shù)器，除法器計數(shù)器和除法器 IC 是數(shù)字邏輯器件，可對輸入發(fā)生的邏輯轉(zhuǎn)換進(jìn)行計數(shù)，然后使用多個并行輸出重新發(fā)送累加的計數(shù)，和/或生成單個輸出信號轉(zhuǎn)換，從而對應(yīng)用某些整數(shù)數(shù)量輸入信號轉(zhuǎn)換進(jìn)行響應(yīng)。除了簡單的事件計數(shù)，它們還可用于各種頻率合成應(yīng)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.
