1. General description

The 74ALVC374 is an octal positive-edge triggered D-type flip-flop with 3-state outputs. The

device features a clock (CP) and output enable (OE) inputs. The flip-flops will store the state of

their individual D-inputs that meet the set-up and hold time requirements on the LOW-to-HIGH

clock (CP) transition. A HIGH on OE causes the outputs to assume a high-impedance OFF-state.

Operation of the OE input does not affect the state of the flip-flops . This device is fully specified for

partial power down applications using IOFF. The IOFF circuitry disables the output, preventing the

potentially damaging backflow current through the device when it is powered down.

74ALVC374BQ属于集成电路（IC） > 触发器。安世半导体(中国)有限公司制造生产的74ALVC374BQ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。
