SN74HC273中文资料具有清零端的八路 D 型触发器数据手册TI规格书

描述 Description

The SNx4HC273 devices are positive-edge-triggered D-type flip-flops with a direct active low clear (CLR) input.

Information at the data (D) inputs meeting the setup time requirements is transferred to the Q outputs on the positive-going edge of the clock (CLK) pulse. Clock triggering occurs at a particular voltage level and is not related directly to the transition time of the positive-going pulse. When CLK is at either the high or low level, the D input has no effect at the output.

特性 Features

• Wide Operating Voltage Range of 2 V to 6 V
• Low Power Consumption, 80-µA Maximum ICC
• ±4-mA Output Drive at 5 V
• Contain Eight Flip-Flops With Single-Rail Outputs
• Individual Data Input to Each Flip-Flop
• On Products Compliant to MIL-PRF-38535, All Parameters Are Tested Unless Otherwise Noted. On All Other Products, Production Processing Does Not Necessarily Include Testing of All Parameters.

简介

SN74HC273属于集成电路（IC）的触发器。由TI制造生产的SN74HC273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。
