描述 Description

CD4027B is a single monolithic chip integrated circuit containing two identical complementary-symmetry J-K flip flops. Each flip-flop has provisions for individual J, K, Set, Reset, and Clock input signals. Buffered Q and Q signals are provided as outputs. This input-output arrangement provides for compatibile operation with the RCA-CD4013B dual D-type flip-flop.

The CD4027B is useful in performing control, register, and toggle functions. Logic levels present at the J and K inputs along with internal self-steering control the state of each flip-flop; changes in the flip-flop state are synchronous with the postitive-going transition of the clock pulse. Set and reset functions are independent of the clock and are initiated when a high level signal is present at either the Set or Reset input.

The CD4027B types are supplied in 16-lead hermetic dual-in-line ceramic packages (F3A suffix), 16-lead dual-in-line plastic packages (E suffice), 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

• 100% tested for quiescent current at 20 V
• Noise margin (over full package-temperature range):
• 2 V at VDD = 10 V
• 5 V, 10 V, and 15 V parametric ratings
• Meets all requirements of JEDEC tentative standard No. 138, standard specifications for description of ’B’ series CMOS devices

简介

CD4027B属于集成电路（IC）的触发器。由TI制造生产的CD4027B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。
