产品型号74F74PC的概述

74F74PC 芯片概述 74F74PC是一款双D触发器（D Flip-Flop），其属于74系列逻辑芯片之一。D触发器广泛用于数字电路中，以存储一个单独的位（bit）信息。74F74PC具有高性能特性，特别适合用于高速数据处理和高频应用。它的主要功能是将输入信号存储在输出中，仅在时钟信号的上升沿（或下降沿）处更新输出状态。 74F74PC的详细参数 74F74PC芯片具有如下主要参数： - 工作电压范围：4.5V至5.5V，通常在5V供电下工作。 - 输入电压范围：低电平通常小于0.8V（逻辑低），而高电平则大于2.0V（逻辑高）。 - 功耗：典型功耗在逻辑高和低之间变化，特别是其静态功耗较低，使得该芯片在功耗敏感的应用中优选。 - 工作温度范围：通常在-40°C到85°C的范围内操作。 - 时钟频率：最大工作频率通常可以达到100MHz。 - 传输延迟：在50-100ns之间，取决...

Dual D-Type Positive Edge-Triggered Flip-Flop

the outputs until the next rising edge of the Clock Pulse

input.

General Description

The F74 is a dual D-type flip-flop with Direct Clear and Set

inputs and complementary (Q, Q) outputs. Information at

the input is transferred to the outputs on the positive edge

of the clock pulse. Clock triggering occurs at a voltage level

of the clock pulse and is not directly related to the transition

time of the positive-going pulse. After the Clock Pulse input

threshold voltage has been passed, the Data input is

locked out and information present will not be transferred to

Asynchronous Inputs:

LOW input to S_Dsets Q to HIGH level

LOW input to C_Dsets Q to LOW level

Clear and Set are independent of clock

Simultaneous LOW on C_Dand S_D

makes both Q and Q HIGH
