描述 Description

The MC74LCX16374 is a high performance, non-inverting 16-bit D-type flip-flop operating from a 2.3 to 3.6V 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 5.5V allows MC74LCX16374 inputs to be safely driven from 5V devices.The MC74LCX16374 consists of 16 edge-triggered flip-flops with individual D-type inputs and 5V-tolerant 3-state true outputs. The buffered clocks (CPn) and buffered Output Enables (OEnbar) are common to all flip-flops within the respective byte. The flip-flops will store the state of individual D inputs that meet the setup and hold time requirements on theLOW-to-HIGH Clock (CP) transition. With the OEbar LOW, the contents ofthe flip-flops are available at the outputs. When the OEbar is HIGH, the outputs go to the high impedance state. The OEbar input level does not affect the operation of the flip-flops.

简介

MC74LCX16374属于集成电路（IC）的触发器。由ONSEMI制造生产的MC74LCX16374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。
