CD40174B中文资料CMOS 六路 D 类触发器数据手册TI规格书

描述 Description

Cd40174B consists of six identical ’D’-type flip-flops having independent DATA inputs. The CLOCK and CLEAR\\ inputs are common to all six units. Data are transferred to the Q outputs on the positive-going transition of the clock pulse. All sic flip-flops are simultaneously reset by a low level on the CLEAR\\ input.
The CD40174B types are supplied in 16-lead hermetic dual-in-line ceramic packages (F3A suffix), 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (M, M96, MT and NSR suffixes), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).

特性 Features

• 5-V, 10-V, and 15-V parametric ratings
• 100% tested for quiescent current at 20 V
• Noise margin (full package-temperature range) =         1 V at VDD = 5 V         2 V at VDD = 10 V      2.5 V at VDD = 15 V
• Applications:
• Buffer/Storage Registers
• Pattern Generators

简介

CD40174B属于集成电路（IC）的触发器。由TI制造生产的CD40174B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。
