MC74HCT595A中文资料Shift Register 3-State, TTL数据手册ONSEMI规格书

描述 Description

The MC74HCT595A consists of an 8 bit shift register and an 8 bit D-type latch with three state parallel outputs. The shift register accepts serial data and provides a serial output. The shift register also provides parallel data to the 8 bit latch. The shift register and latch have independent clock inputs. This device also has an asynchronous reset for the shift register. The HCT595A directly interfaces with the SPI serial data port on CMOS MPUs and MCUs. The device inputs are compatible with standard CMOS or LSTTL outputs.

特性 Features

• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 4.5 to 5.5 V
• Low Input Current: 1.0 uA
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance with the Requirements Defined by JEDECStandard No. 7A
• Chip Complexity: 328 FETs or 82 Equivalent Gates

简介

MC74HCT595A属于集成电路（IC）的移位寄存器。由制造生产的MC74HCT595A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。
