Low−Voltage CMOS 16−Bit D−Type Flip−Flop

With 5 V−Tolerant Inputs and Outputs (3−State, Non−Inverting)

The MC74LCX16374 is a high performance, non−inverting 16−bit D−type flip−flop operating from a 2.3 V to 3.6 V supply. The device is byte controlled. Each byte has separate Output Enable and Clock Pulse inputs. These control pins can be tied together for full 16−bit operation. High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. A VI specification of 5.5 V allows MC74LCX16374 inputs to be safely driven from 5.0 V devices.

M74LCX16374DTR2G属于集成电路（IC） > 触发器。安森美半导体公司制造生产的M74LCX16374DTR2G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。
