SN74LS107AN集成电路（IC）的触发器规格书PDF中文资料

SN74LS107AN属于集成电路（IC）的触发器。由德州仪器制造生产的SN74LS107AN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 107 contain two independent JK flip-flops with

individual JK, clock, and direct clear inputs. The ‘107

is a positive pulse-triggered flip-flop. The J-K input data

is loaded into the master while the clock is high and

transferred to the slave and the outputs on the high-to-

low clock transistion. For these devices the J and K inputs

must be stable while the clock is high.

The 'LS107A contain two independent negative-edge-

triggered flip-flops. The J and K inputs must be stable

prior to the high-to-low clock transition for predictable

operation. When the clear is low, it overrides the clock

and data inputs forcing the Q output low and the Q

output high.

The SN54107 and the SN54LS107A are characterized

for operation over the full military temperature range of

~55°C to 125°C. The SN74107 and the SN74LS107A

are characterized for operation from 0°C to 70°C.
