74F299数据手册集成电路（IC）的移位寄存器规格书PDF

描述 Description

General Description
The 74F299 is an 8-bit universal shift/storage register with 3-STATE outputs. Four modes of operation are possible: hold (store), shift left, shift right and load data. The parallel load inputs and flip-flop outputs are multiplexed to reduce the total number of package pins. Additional outputs, Q0-Q7, are provided to allow easy serial cascading. A separate active LOW Master Reset is used to reset the register.

特性 Features

■ Common parallel I/O for reduced pin count
■ Additional serial inputs and outputs for expansion
■ Four operating modes: shift left, shift right, load and store
■ 3-STATE outputs for bus-oriented applications
■ Guaranteed 4000V minimum ESD protection

应用 Application

■ Guaranteed 4000V minimum ESD protection

简介

74F299属于集成电路（IC）的移位寄存器。由制造生产的74F299移位寄存器移位寄存器是低级逻辑器件，通常用于在串行和并行方式之间转换数字逻辑信号形式的数据，或在数字字内移动数据位的位置。移位寄存器通常使用集成到一个设备中的一组触发器来实现，常用于集成度更高的逻辑器件，但仍可用于 I/O 扩展等应用，在这些应用中离散形式的函数可能会非常有用。
