74LVC74数据手册集成电路（IC）的触发器规格书PDF

描述 Description

The 74LVC74 is a dual D-type flip-flop positive edge-triggered with set and reset. This device accepts a wide supply voltage range from 1.2V to 3.6V. nD are individual data inputs, nCP are clock inputs, nSD and nRD are set inputs, nQ and nQ are complementary outputs.
The set and reset are non-synchronous inputs (active low) and clock inputs can be operated independently. When clock pulse is in the transition of low-to-high, data at the nD inputs will be transmitted to the nQ outputs. For predictable outputs performance, prior set-up time must be required necessarily by nD inputs to the low-to-high clock transition.
Schmitt trigger action features the high tolerance of over-voltage for inputs/outputs data and control inputs and slower input rise and fall times. This device is suitable for down-translation in a mixed-voltage environment.
