M74HC112B1R集成电路（IC）的触发器规格书PDF中文资料

M74HC112B1R属于集成电路（IC）的触发器。由意法半导体集团制造生产的M74HC112B1R触发器触发器是能够存储单个逻辑状态或信息“位”的基本数字存储器件。这些器件至少有两个输入；一个或多个用于传递要存储的数据，另一个用于指示存储该数据的时间点。不同的触发器类型，例如 D（延迟）、SR（置位复位）和 JK，对提供给其输入的信号有不同的响应，可用于实现不同的逻辑功能。这些器件与锁存器的不同之处在于它们是边缘敏感器件，其保持的逻辑状态仅在接收到有效时钟信号时才会改变。

DESCRIPTION

The M54HC112 is an high speed CMOS DUAL J-K FLIP-FLOP WITH PRESET AND CLEAR fabricated with silicon gate C2MOS technology.

The M54HC112 dual JK flip-flop features individual J, K, clock, and asynchronous set and clear inputs for each flip-flop. When the clock goes high, the inputs are enabled and data will be accepted. The logic level of the J and K inputs may be allowed to change when the clock pulse is high and the bistable will function as shown in the truth table. Input data is transferred to the input on the negative going edge of the clock pulse.
